[Conventional technology]

The technology disclosed in Japanese Patent Application Laid-Open No. 2000-292182 is known as a system capable of appropriately switching the presentation form of the delivered content according to the situation of the terminal device. In this conventional technique, advertising information is transmitted to a terminal device mounted on a mobile body such as an automobile. The terminal device that has received the advertisement information appropriately switches the presentation form of the advertisement information according to the situation of the terminal device (for example, whether the moving body on which the terminal device is mounted is moving or stopped). As a result, it is possible to notify the driver of the moving body of the advertising information in a safe state that does not interfere with the driving.

【0003】

[Problems to be Solved by the Invention]

Senders of content such as advertising information often want to specify a form in which the terminal device presents the content according to the content as well as the situation of the terminal device. For example, if the sender thinks that the content has characteristics in the image and the characteristics of the content cannot be sufficiently transmitted depending on the form of sound, even if the moving body equipped with the terminal device is moving. Even so, it is desirable to present the content at least in the form of a still image or a moving image in which frames are thinned out.

【0004】

However, according to the above-mentioned prior art, the form in which the terminal device presents the content such as advertisement information is predetermined for each situation of the terminal device and reflects the intention of the sender (for example, depending on the content). I couldn't change it. According to the prior art, when the moving body is moving, the advertising information is presented in the form of voice regardless of the content of the advertising information, and when the moving body is stopped, the advertising information is voiced. And presented in the form of images.

【0005】

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1. Outline of the present invention FIG. 1 shows the configuration of the content distribution service system 1 of the present invention.

【0026】

The content distribution service system 1 includes a service center 201 and a terminal device 100. The service center 201 and the terminal device 100 are connected by a communication path 250.

【0027】

The terminal device 100 is mounted on the mobile body 110. The mobile 110 is typically an automobile.

【0028】

The communication path 250 may include any network such as various LANs including wireless LAN, WAN, telephone line, wireless telephone line and the like. Considering that the terminal device 100 can be mounted on the mobile body 110 and moved, the communication path 250 preferably includes a wireless network. As a medium for transmitting information in a wireless network, for example, electromagnetic waves or infrared rays can be used.

【0029】

The service center 201 includes a content database 205, a CPU 204, and a transmitter 202. The service center 201 transmits the distribution data 251 to the terminal device 100 through the communication path 250. The service center 201 can be any processing device, for example a server computer. The service center 201 is managed, for example, by a sender 211 who wishes to deliver the content. In addition, in this specification, a "sender" means a provider of a content distribution service, and it does not matter whether or not it is a person who created the content.

【0030】

FIG. 2 shows an example of the structure of the distribution data 251. The distribution data 251 includes the attribute data 252 and the content data 253. The delivery data 251 has, for example, a packet form in which the attribute data 252 is included in the packet header and the content data 253 is included in the data packet. The attribute data 252 specifies a condition related to the situation of the terminal device 100 (FIG. 1) and a content presentation form corresponding to the condition. The content data 253 is data representing a predetermined content. In the example shown in FIG. 2, the content data 253 includes video data and audio data.

【0031】

Line 261 specifies the condition condition => = 20km / h "" and the content presentation form method = sound, video / frame1 corresponding to the condition. In line 261, if the situation of the terminal device 100 satisfies that the moving speed of the mobile body 110 on which the terminal device 100 is mounted is 20 km / h or more, the terminal device 100 is the first frame of audio and video ( Indicates that the content represented by the content data 253 should be presented in the form of presenting only frame1). In this case, the content is presented as audio and still images.

【0032】

Similarly, in line 262, if the situation of the terminal device 100 satisfies that the moving speed of the mobile body 110 on which the terminal device 100 is mounted is less than 20 km / h, the terminal device 100 is voiced and one frame per second. Indicates that the content should be presented in the form of a video that has been decimated (ie, in a form of reduced quality). In this case, the content is presented as audio and poor quality video.

【0033】

Line 263 indicates that the terminal device 100 is in the form of audio and undecimated video (ie, degraded quality) if the condition of the terminal device 100 satisfies that the mobile body 110 on which the terminal device 100 is mounted is stopped. Indicates that the content should be presented in a form that does not allow it. In this case, the content is presented as audio and video that does not degrade quality.

【0034】

In the example shown in FIG. 2, the attribute data 252 uses the type of media (for example, still image, moving image, and / or audio) for presenting the content as the content presenting form corresponding to the condition regarding the situation of the terminal device 100. Specifies the quality of the media (for example, the number of frames per second of the video).

【0035】

The type of media may include, for example, text (a form in which content is presented by a character string). Alternatively, the number of audio playback channels may be specified as the quality of the media.

【0036】

In this way, by designating the type of media for presenting the content and the quality of the media as the content presentation form corresponding to the conditions related to the situation of the terminal device 100, the optimum content according to the situation of the terminal device 100 is specified. Content can be presented in the form.

【0037】

For example, assuming that the content data 253 includes still image data, moving image data, and audio data, when the moving body 110 equipped with the terminal device 100 is in the stopped state, only the moving image data and the audio data can be reproduced. , The content is presented as video and audio, and when the moving object 110 is in a low-speed running state, the content is presented as still image and audio by playing back only the still image data and the audio data, and the moving object 110 presents the content. In the high-speed running state, the content can be presented as voice by reproducing only the voice data. As a result, the content can be presented to the driver 111 in an appropriate form while minimizing the risk of an accident caused by the driver 111 of the moving body 110 driving aside.

【0038】

In order to reduce the risk of accidents caused by the driver 111, it is also effective to reduce the number of voice reproduction channels (decrease the voice quality) when the moving body 110 is in a high-speed driving state. Compared to monaural audio (audio with 1 playback channel), stereo audio (audio with 2 or more playback channels) is more likely to be confused by the driving operation performed by driver 111 due to the stereo sound effect. Because.

【0039】

In the example shown in FIG. 2, the attribute data 252 is described in text format. However, the attribute data 252 may be described in the form of binary data.

【0040】

The operation of the terminal device 100 that has received the distribution data 251 will be described with reference to FIG. 1 again.

【0041】

The terminal device 100 receives the distribution data 251 transmitted from the service center 201 and outputs the data output unit 101 to the determination unit 103 described later, the acquisition unit 102 for acquiring the status of the terminal device 100, and the determination unit 103. , The presentation unit 104 and the like.

【0042】

The data output unit 101 may have a memory (not shown) for temporarily storing the distribution data 251 transmitted to the data output unit 101.

【0043】

In the example shown in FIG. 1, the acquisition unit 102 acquires the moving speed of the moving body 110 on which the terminal device 100 is mounted as the situation of the terminal device 100. The moving speed of the moving body 110 can be obtained, for example, by measuring the number of rotations of the wheels of the moving body 110 per unit time. In this way, when the acquisition unit 102 acquires the moving speed of the moving body 110, it is possible to acquire whether the moving body 110 is in the high-speed traveling state or the stopped state. However, the situation of the terminal device 100 acquired by the acquisition unit 102 is not limited to the moving speed of the moving body 110 on which the terminal device 100 is mounted.

【0044】

The acquisition unit 102 may acquire, for example, the presence or absence of a passenger of the moving body 110 (a person other than the driver 111 of the moving body 110). The presence or absence of a passenger on the moving body 110 can be obtained, for example, by arranging a weight sensor, an infrared sensor, an image sensor, or the like on the seat of the moving body 110.

【0045】

Alternatively, the acquisition unit 102 may acquire the duration of the state in which the moving speed of the moving body 110 is equal to or less than a predetermined value. If the duration of the moving speed of the moving body 110 is equal to or less than a predetermined value and exceeds a certain value, the moving body 110 can be considered to be involved in a traffic jam.

【0046】

Further, when the acquisition unit 102 includes a GPS (Grobal Positioning System), the acquisition unit 102 can detect the position of the terminal device 100. By detecting a change in the position of the terminal device 100 over time, it is possible to acquire the moving direction of the moving body 110 on which the terminal device 100 is mounted. When the acquisition unit 102 has a clock function, the terminal device 100 can acquire the time when the content is presented.

【0047】

The determination unit 103 determines whether or not the status of the terminal device 100 acquired by the acquisition unit 102 satisfies the condition specified by the attribute data 252 included in the distribution data 251.

【0048】

When the determination unit 103 determines in the determination unit 103 that the status of the terminal device 100 acquired by the acquisition unit 102 satisfies the condition specified by the attribute data 252 included in the distribution data 251, the presentation unit 104 attributes the content. Present in the presentation format specified by data 252. The presentation unit 104 includes, for example, a speaker for presenting the content as audio and a display for presenting the content as a still image, moving image, or text.

【0049】

The content distribution service is realized by the service center 201 executing a process of transmitting distribution data 251 to the terminal device 100 (content distribution process).

【0050】

FIG. 3 shows a procedure in which the service center 201 executes the content distribution process. The content distribution process is performed by the CPU 204 (Fig. 1) executing a program that expresses the content distribution process. This process is started, for example, by giving a predetermined command to the service center 201 (processing device) by the sender 211 (FIG. 1) who wants to deliver the content.

【0051】

The procedure of the content distribution process will be described in detail below.

【0052】

Step S301: Content data 253 representing a predetermined content is read from the content database 205. Content data 253 is stored in advance in the content database 205. The predetermined content is, for example, the content that the sender 211 desires to deliver. Such content can be, for example, an advertisement. Alternatively, such content can be a movie.

【0053】

The content data 253 is not limited to being acquired by reading from the content database 205. For example, the content data 253 may be acquired by the service center 201 receiving from the creator of the content via any network.

【0054】

Step S302: The attribute data 252 that specifies the condition regarding the status of the terminal device 100 to which the data (attribute data 252 and the content data 253) is sent and the content presentation form corresponding to the condition is acquired. The attribute data 252 can be acquired, for example, by reading the content data 253 together with the content database 205. Alternatively, it may be acquired by appropriately creating the content data 253 acquired in step S301.

【0055】

As described above, in step S301 and step S302, the CPU 204 (FIG. 1) of the service center 201 functions as an acquisition unit for acquiring the content data 253 and the attribute data 252.

【0056】

Step S303: The content data 253 acquired in step S301 and the attribute data 252 acquired in step S302 are transmitted to the terminal device 100. In such transmission, for example, as described above with reference to FIG. 2, the transmission unit 202 distributes data as one (same) packet containing the attribute data 252 in the header and the content data 253 in the data packet. This is done by transmitting 251 to the terminal device 100.

【0057】

As described above, in the present invention, the content data and the attribute data are transmitted to the terminal device 100. Therefore, the attribute data can be configured according to the intention of the content distribution service provider (content sender). For example, attribute data can be created depending on the content. As a result, the intention of the sender can be reflected in the form in which the terminal device presents the content according to the situation of the terminal device.

【0058】

In the example described above with reference to FIGS. 1 and 3, distribution data 251 is transmitted in one direction from the service center 201 (FIG. 1) to one terminal device 100 (FIG. 1). However, the number of terminal devices 100 to which the distribution data 251 is transmitted is not limited to one. The service center 201 may simultaneously transmit (broadcast) the distribution data 251 to an unspecified number of terminal devices 100. The form of transmitting the distribution data 251 from the service center 201 to one terminal device 100 (Fig. 1) in one direction and the form of broadcasting the distribution data 251 to an unspecified number of terminal devices 100 all at once are available. It is preferably used when the communication path 250 is unidirectional.

【0059】

Alternatively, when the communication path 250 is bidirectional, the service center 201 may transmit the distribution data 251 in response to a request from the terminal device 100.

【0060】

Further, the application of the present invention is not limited to the content data 253 and the attribute data 252 being included in one distribution data 251 and transmitted. The content data 253 and the attribute data 252 may be transmitted as separate data and received by the terminal device 100 via different networks. For example, the terminal device 100 may receive the content data 253 corresponding to the attribute data 252 via the wireless network after receiving the attribute data 252 via the Internet.

【0061】

The terminal device 100 may adopt a method (download method) in which the presentation of the content is started after the reception of the entire content data 253 is completed, or the content data 253 starts from the portion where the reception is completed. A method of starting the presentation (stream method) may be adopted. However, in any case, it goes without saying that the reception of the attribute data 252 must be completed in order to determine the presentation form prior to the start of the presentation of the content.

【0062】

Further, the communication between the service center 201 and the terminal device 100 is not limited to packet communication, and any communication protocol may be used. 2. Example of data structure of distribution data Hereinafter, a specific example of the data structure of the distribution data 251 will be described with reference to FIGS. 4 to 7. FIG. 4, FIG. 5 and FIG. 7 all show an example in which the distribution data 251 is described in the XML format. FIG. 6 shows an example in which the attribute data 252 included in the distribution data 251 is described in the XML format. However, the format for describing the distribution data 251 and the attribute data 252 is not limited to this. The delivery data 251 can be described in any format that can be interpreted by the terminal device 100. XML is a format standardized by the World Wide Web Consortium (W3C) for describing the structure of documents. The World Wide Web Consortium is described, for example, on the web page http://www.w3.org. In addition, XML is described in Reference: "Complete Explanation of Standard XML" (Technical Review Co., Ltd.).

【0063】

XML Schema is defined as a method for describing the structure of an XML document. XML Schema can be found on the W3C web page http://www.w3.org.

【0064】

The distribution data 251 can be described in the MPEG-7 format by using the MPEG-7 Description Definition Language which is an extension of the above XML Schema. MPEG-7 is a standard for keywords that describe the characteristics and contents of multimedia contents, established by the International Organization Standardization (ISO) and the International Electrotechnical Commission (IEC), and is a web page. It is described at http://www.cselt.it/mpeg/standards.htm.

【0065】

In the examples shown in FIGS. 4-7, the terms "condition" and "location" are used to specify conditions relating to the status of the terminal device 100.

【0066】

The term "method" is used to specify the quality at which the terminal device 100 reproduces the content data.

【0067】

The word "type" is used to specify the type of content data (ie, the type of media). The fact that the "type" is "sound", "video", "image" and "text" indicates that the types of content data are audio, video, still image and text, respectively. The terminal device 100 performs a reproduction process according to the type of these content data.

【0068】

FIG. 4 shows an example of distribution data 251 described in XML format.

【0069】

The distribution data 251 includes a part 351 to a part 355.

【0070】

Part 351 indicates that the audio data defined in the [audio data] section (line 2351) is reproduced when the condition of the terminal device 100 satisfies the condition all. Whether or not the condition of the terminal device 100 satisfies the condition of "all" is determined by the determination unit 103 (FIG. 1). The condition "condition =" all "" is a condition that is always satisfied regardless of the situation of the terminal device 100. Therefore, part 351 indicates that the audio data is always reproduced.

【0071】

Part 351 does not specify the quality of playing audio data. If no quality for reproducing the audio data is specified, the terminal device 100 reproduces the audio data at the default quality (eg, the highest quality available).

【0072】

Part 352 indicates that if the situation of the terminal device 100 satisfies the condition of "stop", the data labeled "videodata" is reproduced with the quality of "all". The data labeled "videodata" is defined in part 355 (line 2355).

【0073】

The condition of "stop" is satisfied when the terminal device 100 is stopped (that is, the mobile body 110 on which the terminal device 100 is mounted is stopped).

【0074】

A quality of "all" indicates that the data will be played with the highest quality available. This means that when the data is moving image data, the data is played back without thinning out the moving image frames at all. The number of frames per second when the video frames are played back without being thinned out is, for example, 30 frames.

【0075】

Part 353 indicates that the data labeled "videodata" is reproduced with a quality of "1frameps" when the condition of the terminal device 100 satisfies the condition "<20km / h". The data labeled "videodata" is defined in part 355. In this way, the moving image data defined in part 355 is played back in common when the status of the terminal device 100 satisfies the condition of "stop" and the condition of "<20km". To.

【0076】

The condition "<20km / h" is satisfied when the moving speed of the terminal device 100 is less than 20km / h (that is, the moving body 110 is moving at less than 20km / h).

【0077】

The quality of "1frameps" indicates that the video is displayed by thinning out the frames of the video (decreasing the quality) so that one frame is displayed per second.

【0078】

In part 354, if the condition of the terminal device 100 satisfies the condition "> = 20km / h", the image data defined in the "[Still image data]" section (line 2354) is reproduced. Show that. The condition "> = 20km / h" is satisfied when the moving speed of the terminal device 100 is 20km / h or more (that is, the moving body 110 is moving at 20km / h or more).

【0079】

In the example shown in FIG. 4, the content is presented in the form of audio and non-thinned video when the mobile 110 is stationary, and when the mobile 110 is moving at less than 20 km / h. The content is presented in the form of audio and moving images thinned to one frame per second, and when the moving speed of the moving body 110 is 20 km / h or more, the content is presented in the form of audio and still images.

【0080】

If the situation of the terminal device 100 changes during the presentation of the content, the content may be presented according to the presentation form according to the changed situation. For example, in the example shown in FIG. 4, if the moving body 110 is stopped at the time when the presentation of the content is started, the content is presented in the form of audio and undecimated moving image. After that, when the moving body 110 starts moving and the moving speed becomes 20 km / h or more, the content may be presented in the form of audio and still images. In order to enable such processing, when the terminal device 100 receives the distribution data 251, the terminal device 100 transfers the image data defined in the [Still image data] section (line 2354) to the terminal device 100. It is stored in the internal memory (not shown) of the data output unit 101.

【0081】

In the example shown in FIG. 4, of the distribution data 251, the row 1351, the portion 352, the portion 353 and the row 1354 correspond to the attribute data 252, and the row 2351, the row 2354 and the row 2355 correspond to the content data 253. ..

【0082】

FIG. 5 shows another example of delivery data 251 written in XML format.

【0083】

In the example shown in FIG. 5, the delivery data 251 includes parts 361 to 363.

【0084】

Part 361 is identical to part 351 described above with reference to FIG.

【0085】

Part 362 indicates that when the condition of the terminal device 100 satisfies the condition of "<20km / h", the moving image data defined in the "[video data]" section is reproduced.

【0086】

Part 363 indicates that the text data defined in the "[text data]" section is reproduced when the condition of the terminal device 100 satisfies the condition "=> 20 km / h".

【0087】

In the example shown in FIG. 5, the specification of the quality for reproducing the data is omitted.

【0088】

The attention distribution paid by the driver 111 of the moving body 110 to the still image is smaller than the attention distribution paid to the moving image. Further, by lowering the quality of displaying the moving image, it is possible to reduce the attention distribution paid to the moving body 110 by the driver of the moving body 110. Therefore, from the viewpoint of accident prevention, as the situation of the moving body 110 changes from a stopped state to a low-speed running state to a high-speed running state, the image to be reproduced generally changes from a high-quality moving image to a low-quality moving image to a still image. It is preferable to let it. However, such changes in image quality and media type are preferably specified depending on the content to be delivered.

【0089】

Further, the image quality and media type (ie, content presentation form) specified by the attribute data 252 is further determined by the user of the terminal device 100 (eg, the driver 111 of the mobile 110 carrying the terminal device 100). It may be possible to change. For example, if the driver 111 is not very proficient in driving a moving body 110 (for example, a car), the image is not displayed while the moving body 110 is running, regardless of the moving speed. The terminal device 100 may be set in advance. When the user specifies the content presentation form by such a setting, the specification takes precedence over the specification of the content presentation form by the attribute data 252.

【0090】

Such a setting can be achieved by providing the presentation unit 104 with an interface capable of user input so that the acquisition unit 102 acquires the user input as the status of the terminal device 100. Alternatively, the above setting can be achieved by providing a separate input device in the terminal device 100 so that the acquisition unit 102 acquires the user input as the status of the terminal device 100.

【0091】

As a condition relating to the situation of the terminal device 100, a condition other than the moving speed of the mobile body 110 on which the terminal device 100 is mounted may be specified.

【0092】

FIG. 6 shows an example of attribute data 252 described in XML format. In the example shown in FIG. 6, the position of the terminal device 100 is specified as a condition relating to the situation of the terminal device 100.

【0093】

The attribute data 252 includes a portion 501 and a portion 502.

【0094】

Part 501 indicates that if the status of the terminal device 100 satisfies the condition location = A town, the data having the label Atown.mpg (for example, the file name) is reproduced. The condition of location = Atown is satisfied when the position of the terminal device 100 is inside the town A.

【0095】

Similarly, part 502 indicates that the data labeled "Btown.mpg" is regenerated if the status of the terminal device 100 satisfies the condition location = "Btown". The condition of location = B town is satisfied when the position of the terminal device 100 is inside B town. Hereinafter, the data having the labels "Atown.mpg" and "Btown.mpg" are simply referred to as data "Atown.mpg" and data "Btown.mpg", respectively.

【0096】

The data "Atown.mpg" and the data "Btown.mpg" can be, for example, moving image data (content data) representing guidance information of A town and B town, respectively. These content data have not yet been received by the terminal device 100 when the attribute data 252 is received by the terminal device 100. There are the following two procedures for the terminal device 100 to receive "Atown.mpg" and "Btown.mpg" after the attribute data 252 is received by the terminal device 100.

【0097】

In one procedure, the terminal device 100 requests the required data of the data "Atown.mpg" and the data "Btown.mpg" toward the service center 201 (Fig. 1), and the service center 201 requests the required data. This is a procedure for transmitting the data requested to the terminal device 100 as the content data 253 in response to. In this case, of the data "Atown.mpg" and the data "Btown.mpg", only the data required for the terminal device 100 is transmitted on the communication path 250 (FIG. 1). Therefore, the bandwidth required for transmission can be saved as compared with the case of transmitting both the data "Atown.mpg" and the data "Btown.mpg". In order to realize such a procedure, the communication path 250 needs to be bidirectional.

【0098】

Another procedure is a procedure in which the service center 201 subsequently transmits the data "Atown.mpg" and the data "Btown.mpg" to the terminal device 100 as the content data 253 after the transmission of the attribute data 252 is completed. In this case, both the data "Atown.mpg" and the data "Btown.mpg" are transmitted on the communication path 250. However, in the terminal device 100, of these data, only the one required by the terminal device 100 (for example, when the position of the terminal device 100 is inside the town A, the data "Atown.mpg") is stored in the memory. do it. Such a procedure can be preferably used when the communication path 250 is unidirectional.

【0099】

A plurality of conditions may be specified in combination as conditions relating to the status of the terminal device 100.

【0100】

FIG. 7 shows yet another example of delivery data 251 written in XML format. In the example shown in FIG. 7, as the condition relating to the situation of the terminal device 100, the condition of the moving speed of the terminal device 100 and the condition of the presence or absence of a passenger of the mobile body 110 on which the terminal device 100 is mounted are specified in combination. ..

【0101】

The distribution data 251 includes a part 601 to a part 604.

【0102】

Part 601 is identical to part 351 described above with reference to FIG.

【0103】

Part 602 indicates that when the condition of the terminal device 100 satisfies the condition of "<20km / h", the moving image data defined in the "[data of moving image A]" section is reproduced.

【0104】

Part 603 indicates that the video data defined in the "[Video B data]" section is played when the condition of the terminal device 100 satisfies the condition "> = 20km / h and guest". Shown. The condition "> = 20km / h and guest" is satisfied when the moving speed of the terminal device 100 is 20km / h or more and the moving body 110 equipped with the terminal device 100 has a passenger.

【0105】

In part 604, if the condition of the terminal device 100 satisfies the condition "> = 20km / h and noguest", the still image data defined in the "[Still image data]" section is reproduced. Is shown. The condition "> = 20km / h andnoguest" is satisfied when the moving speed of the terminal device 100 is 20km / h or more and there is no passenger in the moving body 110 on which the terminal device 100 is mounted.

【0106】

Since the passenger is not involved in the driving of the moving body 110, presenting the content as a video for the passenger regardless of the moving speed of the terminal device 100 (that is, the moving speed of the moving body 110) is not possible. There is no problem from the viewpoint of accident prevention.

【0107】

As a condition relating to the situation of the terminal device 100, for example, a time or a time zone in which the terminal device 100 presents the content may be specified in addition to the examples shown in FIGS. 4 to 7. As a result, the presentation form of the content can be changed according to the time zone in which the content is presented. For example, if the content is a restaurant advertisement, the terminal device 100 may only present the lunch or dinner menu at an appropriate time. 3. Application example of content distribution service 1 Next, an application example of the content distribution service will be described when the situation of the terminal device 1000 is that there is a passenger of the mobile body 110.

【0108】

FIG. 8 shows an application example of the method of providing the content distribution service of the present invention.

【0109】

The terminal device 1000 according to the present invention is the same as the terminal device 100 shown in FIG. 1 except that it has a second presentation unit 1101 in addition to the first presentation unit 104 (corresponding to the presentation unit 104 in FIG. 1). .. Similar components are designated by the same reference numerals, and the description thereof will be omitted. The number of presentation units may be arbitrary and may be greater than 2. As shown in FIG. 8, when the moving body 110 is an automobile, the first presentation unit 104 may be a front seat display and the second presentation unit 1101 may be a rear seat display.

【0110】

In the example shown in FIG. 8, as passengers other than the driver (not shown), an adult passenger 1111 located in the front seat (passenger seat) next to the driver and a child located in the back seat. The passenger 1102 and the passenger 1102 are located in the moving body 110. In this case, the service center 201 transmits the distribution data 251 including the content data representing the event information (content) of the × department store. The transmitted distribution data 251 is received by the data output unit 101 of the terminal device 1000 mounted on the mobile body 110.

【0111】

Distribution data 251, attribute data 252 and the near point and a Tsudeta 253.

【0112】

The acquisition unit 102 has a passenger in the front seat and the passenger is an adult 1111 in the terminal device 1000, and has a passenger other than the driver in the rear seat and is on board. Get the situation of the terminal device 1000 that the person is a child 1102. The acquisition of the status of the terminal device 1000 may be achieved by sensing using, for example, a weight sensor provided under each seat, an image sensor provided in the vehicle of the moving body 110, or the like, as described above. As described above, a separate user input device may be provided to acquire input by the user (for example, the driver 111 (FIG. 1), passengers 1102 and 1111 of the mobile body 110 equipped with the terminal device 1000). The status of the terminal device 1000 acquired by the acquisition unit 102 (that is, the adult passenger 1111 is located in the front seat and the child passenger 1102 is located in the back seat) is sent to the determination unit 103.

【0113】

The determination unit 103 determines whether or not the status of the terminal device 1000 satisfies the condition included in the attribute data 252. As a result of the determination, if the condition is satisfied, the content is displayed in the first presentation unit 104 and the second presentation unit 1101.

【0114】

【0118】

FIG. 10 shows the structure of the distribution data 251 shown in FIG.

【0119】

The distribution data 251 includes a part 1301 to a part 1304.

【0120】

In part 1301, if the condition of the terminal device 1000 satisfies the condition = guest, position = front (first condition), [ × Department store 9th floor event information video data] is displayed. It is shown that it is displayed on the first presentation unit 104 (first presentation form). The condition condition = guest, position = front is satisfied when the passenger is an adult and the passenger is located in the front seat. That is, the terminal device 1000 shown in FIG. 8 satisfies this condition.

【0121】

Part 1302 is a video for children of the event information on the 7th floor of the [ × department store] when the condition of the terminal device 1000 satisfies the condition = guest, is_child, position = rear (second condition). Data] is displayed on the second presentation unit 1102 (second presentation form). The condition = guest, is_child, position = rear is satisfied when the passenger is a child and the passenger is located in the back seat. Similarly, the terminal device 1000 shown in FIG. 8 satisfies this condition.

【0122】

In part 1303, if the condition of the terminal device 1000 satisfies the condition condition = guest, position = front preference = child, [ × Department store 7th floor event information video data for adults] is displayed. It is shown that it is displayed on the first presentation unit 104. The condition = guest, position = front preference = child is satisfied when the passenger is an adult, the passenger's position is the front seat, and the preference is a child. For example, in the terminal device 100 of FIG. 8, the passenger 1111 is satisfied when he / she inputs that his / her preference is a child. "Preference is a child" means that when the user is an adult, the user wants to obtain information about the child, such as an event for children.

【0123】

In part 1304, if the condition of the terminal device 1000 satisfies the condition condition = guest, position = front preference = foods sex = female, [ × Department store basement 1st floor event information Video data] is displayed on the first presentation unit 104. The condition = guest, position = front preference = foods sex = female is when the passenger is an adult female, the passenger's position is the front seat, and the preference is food. Is filled with. For example, in the terminal device 1000 of FIG. 8, the passenger 1111 is satisfied when he / she inputs that the gender is female and the preference is food. "Preference is grocery" indicates that the user wants to obtain information about the grocery.

【0124】

By configuring the terminal device 1000 and the distribution data 251 in this way, the service center 201 has several presentation units (first presentation unit 104 and second presentation unit 1101) of the same mobile body 110, respectively. Content containing information on the type XX department store can be provided in a presentation form (FIGS. 9 (a)-(d)) selected according to the passenger's location and / or the passenger's profile. The passenger position is selected from the group consisting of front seats, front and rear seats, and rear seats. At least one passenger profile is selected from the group consisting of gender, adult or child, age, hobbies, and preferences.

【0125】

In addition, referring to FIGS. 8 to 10, the attribute data specifies the position of the passenger (that is, the presentation destination of the content) as a condition regarding the situation of the terminal device 1000 in advance, whereby the first presentation unit 104 And although the example of presenting the content to at least one of the second presentation unit 1101 has been described, the present invention can be applied even when the attribute data does not specify the position of the passenger as a condition regarding the situation of the terminal device. is there.

【0126】

When there is a passenger of the mobile body 110 on which the terminal device 1000 is mounted, the attribute data does not specify the position of the passenger as a condition regarding the situation of the terminal device 1000, and the first presenting unit 104 and the first presenting unit 104 and the first. An example in which at least one of the presentation units 1101 of 2 presents the content will be described.

【0127】

In this case, the acquisition unit 102 acquires a situation in which an adult passenger and a child passenger are present in the mobile body 110 on which the terminal device 1000 is mounted, as the situation of the terminal device 1000 (FIG. 8). The acquisition unit 102 further acquires the presentation destination designation information that designates at least one of the first presentation unit 104 and the second presentation unit 1101 as the content presentation destination, which is associated with the acquired situation. In this example, the presentation destination designation information is in the form of presenting content corresponding to the situation of the terminal device 1000 in which the adult passenger is located in the front seat (that is, the adult passenger is present). Information that the content should be presented to the presentation unit 104 of 1 and information that the child's passenger is located in the back seat (that is, the situation of the terminal device 1000 that the child's passenger is present). The content should be presented to the second presentation unit 1101 in the form of presenting the content corresponding to). The presentation destination designation information can be acquired, for example, by arranging a weight sensor, an infrared sensor, an image sensor, or the like in the seat of the moving body 110. The status acquired by the acquisition unit 102 and the presentation destination designation information are sent to the determination unit 103.

【0128】

As described above, the determination unit 103 determines whether or not the status of the terminal device 1000 satisfies the condition included in the attribute data 252. As a result of the determination, if the condition is satisfied, the content is presented to at least one of the first presentation unit 104 and the second presentation unit 1101 specified by the presentation destination designation information associated with the situation satisfying the condition. ..

【0129】

FIG. 11 shows another structure of the distribution data shown in FIG.

【0130】

In this case, delivery data 251 includes parts 1110, 1120, 1130 and 1140.

【0131】

Part 1110 is the same except that the condition regarding the position of the passenger has been removed from part 1301 in FIG. The presentation that the situation of the terminal device 1000 satisfies the condition condition = guest (that is, the adult passenger 1111 is present) and that this situation is that the adult passenger 1111 is located in the front seat. When associated with the designated information, "[ × video data of event information on the 9th floor of the department store]" is displayed in the first presentation unit 104. That is, the screen 9001 of FIG. 9A is displayed on the first presentation unit 104.

【0132】

Part 1120 is the same except that the condition regarding the position of the passenger has been removed from part 1302 in FIG. The situation of the terminal device 1000 satisfies the condition condition = guest, is_child (that is, the child passenger 1102 is present), and this situation states that the child passenger 1102 is located in the back seat. When it is associated with the presentation destination designation information, "[ × video data for children of the event information on the 7th floor of the department store]" is displayed in the second presentation unit 1101. That is, the screen 9002 of FIG. 9B is displayed on the second presentation unit 1101.

【0133】

Part 1130 is the same except that the condition regarding the position of the passenger has been removed from part 1303 in FIG. The situation of the terminal device 1000 satisfies the condition condition = guest preference = child (that is, an adult passenger 1111 is present and the preference is a child), and this situation is an adult passenger 1111. When associated with the presentation destination designation information that is located in the front seat, "[ × Department store 7th floor event information adult video data]" is displayed in the first presentation section 104. That is, the screen 9003 of FIG. 9 (c) is displayed on the first presentation unit 104.

【0134】

Part 1140 is the same except that the condition regarding the position of the passenger has been removed from part 1304 in FIG. The condition of the terminal device 1000 satisfies the condition condition = guest preference = foods sex = female (that is, an adult female passenger 1111 is present and the preference is food). If this situation is associated with the destination designation information that the adult female passenger 1111 is located in the front seat, "[ × Video data of the event information on the first basement floor of the department store]" is the first. Is displayed on the presentation unit 104 of. That is, the screen 9004 of FIG. 9 (d) is displayed on the first presentation unit 104.

【0135】

The distribution data 251 in FIGS. 10 and 11 is merely an example. The delivery data 251 can be arbitrarily configured according to the intention of the sender 211 (Fig. 1).

【0136】

In this way, since the terminal device 1000 determines to which presentation unit (first presentation unit 104 or second presentation unit 1101) the content should be presented, the attribute data relates to the status of the terminal device 100 in advance. It is not necessary to specify the position of the passenger (that is, the destination of the content) as a condition. Further, since the sender 211 does not need to prepare the content presentation form according to the position of the passenger, the bandwidth required for transmission can be saved. 4. Application example of content distribution service 2 FIG. 12 shows an application example of the method of providing the content distribution service of the present invention.

【0137】

The service center 201 transmits (broadcasts) distribution data 251 including content data representing the advertisement (content) of the restaurant 801. The distribution data 251 is received by the terminal device 100a mounted on the mobile body 110a and the terminal device 100b mounted on the mobile body 110b. The terminal device 100a and the terminal device 100b may each have the same configuration as the terminal device 100 described with reference to FIG.

【0138】

The mobile 110a is moving east and the mobile 110b is moving north.

【0139】

The distribution data 251 includes attribute data 252 and content data 253.

【0140】

FIG. 13 (a) shows a still image 951a presented to the presentation unit 104 (not shown in FIG. 12, see FIG. 1) of the terminal device 100a. Still image 951a represents restaurant 801 as seen from the west.

【0141】

FIG. 13 (b) shows a still image 951b presented to the presentation unit 104 (not shown in FIG. 12, see FIG. 1) of the terminal device 100b. Still image 951b represents restaurant 801 as seen from the south side.

【0142】

FIG. 14 shows the structure of the attribute data 252 shown in FIG.

【0143】

The condition "direction = north" shown in line 1051 is satisfied when the moving direction of the terminal device is northward. That is, the terminal device 100b shown in FIG. 12 satisfies this condition.

【0144】

The condition "direction = east" shown in line 1052 is satisfied when the moving direction of the terminal device is eastward. That is, the terminal device 100a shown in FIG. 12 satisfies this condition.

【0145】

The data southview.jpg shown in line 1053 is data representing a still image 951b (FIG. 13 (b)). The format of the data "southview.jpg" is, for example, the JPEG format.

【0146】

The data "westview.jpg" shown in line 1054 is data representing a still image 951a (FIG. 13 (a)). The format of the data "westview.jpg" is, for example, the JPEG format.

【0147】

The data "westview.jpg" and the data "southview.jpg" are transmitted (broadcast) to the terminal device 100a and the terminal device 100b as the content data 253. The terminal device 100a accumulates and displays only the data "westview.jpg" among the received content data 253 as necessary data. The terminal device 100b accumulates and displays only the data "southview.jpg" among the received content data 253 as necessary data.

【0148】

In FIG. 14, rows 1051 to 1054 correspond to the attribute data that specifies the conditions related to the status of the terminal devices 100a and 100b and the presentation form of the content (advertisement) corresponding to the conditions, and the data "westview.jpg" and The data "southview.jpg" corresponds to the content data representing the content.

【0149】

By configuring the distribution data 251 in this way, the service center 201 (FIG. 12) is presented differently to the driver of the mobile 110a and the driver of the mobile 110b (shown in FIG. 13 (a)). It is possible to provide an advertisement for the restaurant 801 presented in the form and the form shown in FIG. 13 (b). Such a presentation form is highly preferred for the driver to identify the restaurant 801 while driving the moving object. This is because the driver of the mobile 110a and the driver of the mobile 110b are shown the appearance of the restaurant 801 in the same manner as the scenery seen while driving.

【0150】

In this example, images of the restaurant 801 viewed from different directions were presented to the respective terminal devices based on the moving directions of the terminal device 100a and the terminal device 100b. However, images of the restaurant 801 as viewed from different directions may be presented based on the positions of the terminal device 100a and the terminal device 100b. For example, a terminal device located on the west side of the restaurant 801 (terminal device 100a in the example shown in FIG. 12) is presented with an image of the restaurant 801 viewed from the west side and is located on the south side of the restaurant 801. The terminal device (terminal device 100b in the example shown in FIG. 12) may be presented with an image of restaurant 801 as viewed from the south side.

【0151】

In the example described with reference to FIGS. 12, 13 (a) and 13 (b), and FIG. 14, the attribute data 252 is created as the content (this example) by creating the attribute data 252 according to the intention of the content sender. Then, it is an example showing that it is preferable to make it dependent on advertisement).

【0152】

In the embodiment described in relation to FIGS. 1 to 14, the content distribution representing the content is distributed from the service center 201 (FIG. 1) managed by the sender 211 (FIG. 1). I have explained the service. However, the present invention is not limited to the content data being broadcast via the communication path 250 (FIG. 1). For example, the content data and the attribute data reflecting the sender's intention may be recorded in advance on the information recording medium. The information recording medium may be, for example, an optical disk, a magnetic disk, or the like. When the content data and the attribute data are recorded in advance on the information recording medium, the data output unit 101 of the terminal device 100 (FIG. 1) and the terminal device 1000 (FIG. 8) reproduces the information recording medium and reproduces the data output unit 101. It functions to output the content data and the attribute data to the determination unit 102. In this case, the same components as those in FIG. 1 can be used as the components other than the data output unit 101.

【0153】

In the embodiment described above, it is assumed that the terminal device 100 (or 1000, 100a, 100b) is mounted on the mobile body 110 (or 110a, 110b). It is for the purpose of demonstrating an example in which the situation of the terminal device 100 may change, and should not be construed as intending to limit the present invention to this. The principle of the present invention is applicable to any terminal device 100 provided with an acquisition unit for acquiring the status of the terminal device 100.

【0154】

According to the principle of the present invention, a content distribution service for the visually impaired or the hearing impaired can be easily realized. For example, as the acquisition unit 102 (FIG. 1) of the terminal device 100, use any device capable of inputting whether or not the user of the terminal device 100 is a visually impaired person or a hearing impaired person as the situation of the terminal device 100. As a result, auxiliary voice for the visually impaired, subtitles for the hearing impaired, and the like can be presented to the presentation unit 104.

【0155】

[Effect of the invention]

According to the present invention, data representing a predetermined content and attribute data are transmitted to the terminal device. The attribute data specifies a condition relating to the status of the terminal device and a form of presenting the content according to the condition. By configuring the attribute data according to the intention of the content distribution service provider (content sender), the terminal device reflects the sender's intention in the form of presenting the content according to the situation of the terminal device. be able to.
