BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, some embodiments of the client terminal according to the present invention will be described. The first embodiment is a portable information terminal (PDA) 7,11, a portable audio playback device 8,10, or a mobile phone device 9 incorporated in the information providing system shown in FIG.
【0036】
These client terminals are mobile devices that are carried and moved by the user, and are streaming data of provided information transmitted as RF signals from a plurality of content servers 1, 2, 3, and 4 via the window server 3 and the antenna 6. Is received and displayed on the built-in liquid crystal display (LCD), or the sound is output through a speaker or headphones.
【0037】
The information providing system shown in FIG. 1 distributes streaming data such as provided information to the mobile device having a high-speed communication function. The communication protocol adopted in this system is based on UDP (User Datagram Protocol). UDP is an Internet transport protocol that supports connectionless IP datagram communication. It does not have a retransmission function at the transport layer. Therefore, packet loss affects video and audio as it is.
【0038】
Next, a specific example of the client terminal will be described with reference to FIG. For example, as shown in FIG. 2, the PDA 7 has a RAM 23, a ROM 24, a decoder 25, a touch panel controller 26, a graphic control 28, a VRAM 29, and a communication interface 31 in the semiconductor integrated circuit 20 via an internal bus 21 in the CPU 22. Is connected. The PDA7 of k connects the CPU 22 to an audio codec including an audio data decoder and an audio data encoder, which is not shown, via an internal bus 21. The audio data decoded by the audio codec under the control of the CPU 22 is converted into an analog signal by the audio D / A and supplied to the output terminal.
【0039】
Outside the semiconductor integrated circuit 20, a touch panel 27 is arranged by connecting to the touch panel controller 26, and a display device 30 such as an LCD is arranged by connecting to the graphic controller 28.
【0040】
RAM23 stores a time stamp, which is time information, when a session with the content server is interrupted and the delivered provided information is disconnected. This time stamp is added to the provided information. The progress of the provided information is managed based on this time stamp.
【0041】
When establishing a new session with the content server, the CPU 22 reads the time stamp information when the provided information is disconnected from the RAM 23, and requests the content server to deliver the provided information up to the type stamp.
【0042】
The ROM 24 stores an information processing program based on the client-side information processing method according to the present invention. This information processing program will be described later.
【0043】
Communication interface 31 is a standard protocol for bluetooth Bluetooth, W-CDMA (Wideband Code Division Multiple Access), CDMA2000, HDR, PIAFS (PHS Interner Access Forum Standard) capable of high-speed data transmission of 2 Mbps, and wireless LAN, 2 Mbps, improved. IEEE802.11 for high-speed data transmission of 11 Mbps, IrDA (Infrared Data Associaton), USB (Universal Serial Bus), IEEE1394, analog modem (Analog Modem), cable modem (Cable Modem), which are standards for infrared data communication. It is an interface that enables streaming data communication via optical fiber.
【0044】
The data packet input from the communication interface 31 is analyzed by the CPU 22 or the like, and the compressed stream data is taken out and sent to the decoder 25.
【0045】
The decoder 25 decodes the video signal from the compressed stream data and sends it to the graphic controller 28. The graphic controller 28 sends an image based on the video signal to the LCD 30 via the video RAM 29.
【0046】
The user's operation input by the pen or finger is performed via the touch panel controller displayed on the touch panel 27, and the touch panel controller 26 generates a control signal and sends it to the CPU 22.
【0047】
The CPU 22 decodes the control signal from the touch panel controller 26 and controls the functions of the respective parts as needed. For example, take out the operating system and various application programs from ROM24 and execute them.
【0048】
Next, the window server 5 will be described. The window server 5 is a server that performs connection authentication processing with a client terminal, selects an information providing server based on a distribution request from the client terminal, and relays information provided by the information providing server.
【0049】
The window server 5 first performs a connection process, performs an authentication process based on the authentication information and the like sent from the client terminal, selects an information providing server, and establishes a session between the client terminal and the information providing server.
【0050】
As shown in FIG. 3, the window server 5 inputs the memory 43, the external storage device 44, and the video to the CPU 42 that performs the connection authentication processing and the distribution request processing from the client terminal according to the application program via the internal bus 41. The device 45 and the network interface 46 are connected. Then, the CPU 42 sequentially executes the application program stored in the memory 43 or the external storage device 44.
【0051】
Information provided by the content server is supplied to the video input device 45. In addition, the network interface 46 communicates with the communication interface 31 of the client terminal via Bluetooth Bluetooth, W-CDMA, CDMA2000, HDR, PIAFS, IEEE802.11, IrDA, USB, IEEE1394, Analog Modem, Cable Modem, and optical fiber. Enables all streaming data communication.
【0052】
Next, a content server, which is an information providing server, will be described. Each content server also has almost the same configuration as shown in Fig. 3. The video providing information is supplied to the video input device 45 from a database that stores the video providing information. Further, a network connecting to the window server 5 is connected to the network interface 46.
【0053】
Next, the outline of the operation of the information providing system will be described. The feature of this information providing system is that when the session between the client terminal and the content server is disconnected due to communication conditions, etc., the client terminal becomes the main and after the session is recovered. It is for processing.
【0054】
Specifically, the client terminal periodically records the time stamp of the place where the session is interrupted during the streaming playback in RAM23. Then, when the communication conditions are restored and the session is restored, the connection to the content server is attempted again via the window server 5, and when the connection is made, the time previously recorded in the RAM 23 is recorded. Instruct the content server to proceed with the content up to the stamp.
【0055】
Figure 4 is a transition diagram showing the outline of the operation of the information providing system. First, a session is established between one of the content servers and the client terminal via the window server 5 (step S1).
【0056】
Content is transmitted from the content server to the client terminal via the window server (step S2), and the client terminal performs packet acquisition processing (step S3).
【0057】
The client terminal assembles data from the acquired packet (step S4), and performs data reproduction processing in step S5. At this time, the time stamp is stored in RAM23 (step S6). The time stamps related to the normally played data are updated one after another.
【0058】
Here, when the session is interrupted due to deterioration of communication conditions (step S7), the time stamp of the place where the session is interrupted remains in RAM23.
【0059】
Then, when the communication conditions are restored again, an attempt is made to connect to the window server, and when the connection is made (step S8), the time stamp previously recorded in RAM23 is read (step S9), and that type. Send the stamp to the content server (step S10). At this time, the content server is instructed to fast-forward the content to the time stamp. Regarding fast-forwarding content, especially if it is a server that normally streams, it is possible to issue control instructions through a protocol such as RTSP (Real Time Streaming Protocol), so after establishing a session, it is possible to issue control instructions. The client terminal side may do it uniquely.
【0060】
When the content server receives the time stamp and the instruction (step S11), the content server fast-forwards the content for the time stamp and sends it to the client terminal (step S12).
【0061】
The client terminal performs packet acquisition processing in step S13, assembles data from the packet in step S14, and reproduces the data in step S15. At this time, the time stamp is stored in RAM23 (step S16).
【0062】
The information processing program executed by the client terminal in the information providing system will be described with reference to FIG. This information processing program is stored in ROM 24. CPU22 takes out from ROM24 and executes using RAM23.
【0063】
First, in step S21, it is determined whether or not there is resume information. Since the resume information is the work information immediately before when the power is turned off or the session is interrupted, any of the resume information is generated when there is the resume information.
【0064】
This resume information includes the information immediately before the interruption of the session in step S7 shown in FIG. 4, and here, the time stamp information stored in RAM 23 in step S6.
【0065】
If it is determined in step S21 that NO, that is, no resume information remains, the reproduction process is performed from the first data (step S22). If YES, proceed to step S30 and send the time stamp information to the content server.
【0066】
In step S22, since the session is still established, the client terminal performs the reproduction process from the first data. In step S23, the packet is acquired, and in step S24, data is assembled from the packet.
【0067】
Then, the necessary information and data are obtained in step S25 (YES), and if it is End of data (YES in step S26), the reproduction process is terminated.
【0068】
If the necessary information and data are not obtained in step S25 (NO), the process from step S23 is repeated. If the data is not end-of-data (NO) in step S26, the data reproduction is continued in step S27.
【0069】
Following step S27, step S28 is a process of determining whether or not the information acquisition interval for resume has been reached. If the predetermined information acquisition interval is reached (YES), the process proceeds to step S29 and the time stamp information is obtained. Is stored in RAM23. If the predetermined information acquisition interval has not been reached (NO), the process from step S23 is repeated.
【0070】
When it is determined (YES) that there is resume information in step S21, the session is interrupted as shown in step S7 in FIG. 4, so the client terminal reads the time stamp from RAM23 (in FIG. 4). Step S9), this is sent to the content server in step S30. The system as a whole sends the time stamp shown in step S10 in FIG.
【0071】
Then, the processing of the entire system shifts to the server side, the time stamp is received in step S11 of FIG. 4, and the content for the time stamp is fast-forwarded on the server side in step S12.
【0072】
As described above, the information processing program is a program for causing the client terminal to process the content of the provided information delivered from the information providing server side by establishing a session between the information providing server and the client terminal. The time stamp storage process (step S29 and the provided information stored in RAM23 by the time stamp storage process) when the session with the server is interrupted and the delivered content is disconnected, the time stamp is stored in RAM23. A delivery request process is provided in which the time stamp at the time of disconnection is read (step S9 in FIG. 4), and when a new session is established with the server side, the server side is requested to deliver the content advanced to the time stamp. The delivery requesting process includes steps S9 and S10 of FIG. 4 or step S30 of FIG.
【0073】
As described above, the client terminals such as PDA7 and mobile phone device 9 incorporated in the information providing system shown in FIG. 1 will be connected when the connection is established next after the communication is disconnected. Without imposing a burden on the server side, it is possible to display the video and audio from the disconnected part on the LCD and output the audio from the speaker and headphones, focusing on its own processing.
【0074】
Next, the second embodiment will be described. This second embodiment is also a PDA 7, 11 incorporated in the information providing system shown in FIG. 1, a portable audio playback device 8, 10, or a mobile phone device 9.
【0075】
The configuration of these client terminals is the same as that of PDA7 shown in FIG. However, since the provided information is transmitted in real time using RTP (Real Time Transport Protocol) on UDP from the server side, the contents of the information processing program stored in ROM23 can be changed to RTP (RTP Control Protocol) of RTP. It is the one used. RTCP is a control protocol for confirming delivery and monitoring. The information processing program uses RTCP to evaluate the communication quality. The details of the information processing program will be described later.
【0076】
The information providing system in which the mobile client terminal of the second implementation is incorporated reflects the deterioration of communication quality in the billing. Even if the communication is not disconnected, due to changes in the call status, packet drops may occur partially, and in the case of video, the frame rate may drop significantly or the resolution may drop partially. With regard to sound, noise may be mixed with the sound, or the sound may be interrupted in a part. In particular, in the case of content such as video or music in which copyright is generated and charges are made, this kind of situation causes dissatisfaction to the user.
【0077】
Therefore, in this information providing system, the client terminal has a function to evaluate the communication quality, and after using this to finish viewing the content, the overall communication quality is measured and the communication quality is measured. The processing is done to reduce the billing.

Content is transmitted from the content server to the client terminal via the window server (step S42), and the client terminal performs packet acquisition processing (step S43).
【0080】
The client terminal assembles data from the acquired packet (step S44), and performs data reproduction processing in step S45.
【0081】
At this time, the client terminal evaluates the communication quality in step S46. In RTP-based streaming, the communication quality can be measured by using RTCP, which controls the communication quality. With RTSC, the number of received packets in the total number of packets can be known, and packet loss can be counted. If the packet loss is large, it can be determined that the communication quality has deteriorated. By using this, it is possible to measure the overall communication quality after watching music or video. Then, the client terminal sends the evaluation result of the communication quality to the server side.
【0082】
Then, the content server reflects the evaluation result of the communication quality in the billing (step S47). As a result, in the information providing system, it is possible to reduce the charge depending on the quality of communication.
【0083】
The information processing program executed by the client terminal, which is the second embodiment in the information providing system, will be described with reference to FIG. This information processing program is also stored in ROM 24. CPU22 takes out from ROM24 and executes using RAM23.
【0084】
In step S51, the packet is acquired, and in step S52, data is assembled from the packet.
【0085】
Then, if the necessary information and data are obtained in step S53 (YES), and if it is End of data (YES in step S54), the reproduction process is terminated and the communication quality is improved in step S55. evaluate. The method of evaluating the communication quality has already been described in step S46 in the operation of the entire system shown in FIG.
【0086】
After step S55, the client terminal transmits the evaluation result to the server side in step S56. In response to this, on the server side, the communication quality is reflected in the billing in step S47 shown in FIG.
【0087】
If it is not end-of-data (NO) in step S54, the data reproduction is continued in step S57.
【0088】
As described above, the information processing program is a program for causing the client terminal to process the provided information delivered from the server side by establishing a session between the server side and the client terminal, and is delivered from the server side. The client terminal is provided with an evaluation step (step S55) for evaluating the communication quality related to the provided information and an evaluation notification step (step s56) for notifying the information providing server of the communication quality evaluated by the evaluation process. Is executed.
【0089】

【0092】
The configuration of these client terminals is the same as that of PDA7 shown in FIG. However, since the provided information is transmitted in real time using RTP (Real Time Transport Protocol) on UDP from the server side, the contents of the information processing program stored in ROM23 can be changed to RTP (RTP Control Protocol) of RTP. It is the one used. RTCP is a control protocol for confirming delivery and monitoring. The information processing program uses RTCP to evaluate the communication quality. The details of the information processing program will be described later.
【0093】
In the built-in information providing system, the mobile client terminal of this third implementation stores the time stamp of the point where the communication quality has deteriorated in RAM23, and after the viewing is completed, the user can watch again. It has a function to ask whether or not it is desired, and if so, to display or output video and / or audio following the point of the time stamp in which the communication quality has deteriorated.
【0094】
FIG. 9 is a transition diagram showing an outline of the operation of the information providing system including the client terminal of the third embodiment. First, a session is established between one of the content servers and the client terminal via the window server 5 (step S61).
【0095】
Content is transmitted from the content server to the client terminal via the window server (step S62), and the client terminal performs packet acquisition processing (step S63).
【0096】
The client terminal assembles data from the acquired packet (step S64), and performs data reproduction processing in step S65. At this time, the time stamp is stored in RAM23 (step S66). The time stamps related to the normally played data are updated one after another.
【0097】
Further, the client terminal evaluates the communication quality in step S67. Here, when the communication quality deteriorates due to deterioration of communication conditions or the like (step S68), a time stamp of the place where the communication quality has deteriorated remains in the RAM 23.
【0098】
Then, after outputting music, video, etc., the time stamp recorded in RAM23 is read out (step S69). At this time, in step S70, based on the type stamp, as shown in FIG. 10, there is a point on the LCD30 where the communication quality has deteriorated, so an indication as to whether or not to see it is displayed.
【0099】
When the user wishes to re-view in step S70, a request signal and a time stamp indicating that fact are transmitted to the content server side, and the content server side receives it (step S71). On the content server side, the content from the time stamp is transmitted to the client side terminal (step S72).
【0100】
The client terminal performs packet acquisition processing in step S73, assembles data from the packet in step S74, and reproduces the data in step S75. At this time, it goes without saying that the time stamp is stored in the RAM 23.
【0101】
A specific example of the display on the LCD 30 in the client terminal (PDA7) shown in FIG. 10 will be described. It shows the type stamp of the section where the communication quality was not sufficient, and guides whether you want to watch it again.
