[Technical field to which the invention belongs]

The present invention relates to a broadcast receiving device provided in, for example, a mobile terminal unit and receiving terrestrial broadcasts such as television broadcasts and radio broadcasts.

【0002】

[Conventional technology]

FIG. 11 shows an example of a conventional broadcast receiving device that receives terrestrial broadcasts such as television broadcasts and radio broadcasts. In FIG. 11, the broadcast receiving unit 600 includes an antenna 601, a channel selection unit 602, a demodulation unit 603, a multiple separation unit 604, and a decoding unit 605.

【0003】

Antenna 601 receives broadcast waves. The channel selection unit 602 selects the reception signal of the physical channel to be viewed from the reception signals. The demodulation unit 603 demodulates a coded signal in which the coded data of a plurality of logical channels is multiplexed from the received signal of the physical channel selected by the channel selection unit 602. The multiplex separation unit 604 separates the coded signal of the required logic channel from the coded signal supplied from the demodulation unit 603. The decoding unit 605 decodes the video signal / audio signal from the coded signal of the required logic channel separated by the multiplex separation unit 604. The control unit 606 controls each unit in the broadcast receiving unit 600. The storage unit 607 stores the physical channels selected by the channel selection unit 602, and also stores information necessary for signal processing of each unit. The input unit 608 performs input operations of the broadcast receiving device such as selection of a physical channel to be selected. The display unit 609 includes a speaker (not shown) and outputs a video signal or an audio signal decoded by the decoding unit 605.

【0004】

Next, the operation of the broadcast receiving device will be described.

【0005】

The channel selection unit 602 receives the broadcast signal at the antenna 601. The channel information selected by the viewer by the input unit 608 is supplied to the control unit 606. The control unit 606 supplies a channel selection signal to the channel selection unit 602 according to the channel information, and sets the physical channel for channel selection. The channel selection unit 602 separates the reception signal of the physical channel set by the channel selection signal from the reception signal supplied from the antenna 601. Further, the channel selection unit 602 frequency-converts the separated received signal to generate a channel-selected physical channel modulation signal. This physical channel modulation signal is supplied to the demodulation unit 603. The demodulation unit 603 demodulates the multiplexed coded signal from the physical channel modulation signal supplied from the channel selection unit 602. The demodulation unit 603 has an error correction circuit, and the demodulated coded signal is corrected by the error correction circuit. The multiplexed coded signal in which the error correction is performed is supplied to the multiplex separation unit 604, and the error correction information is supplied to the control unit 606. The multiplex separation unit 604 separates the logical channel to be received according to the multiplexed coded signal supplied from the demodulation unit 603 and the logical channel selection signal supplied from the control unit 606. The coded signal of this separated logic channel is supplied to the decoding unit 605. The decoding unit 605 decodes the video signal and the audio signal from the coded signals of the separated logic channels supplied from the multiplex separation unit 604, and supplies the decoded video signal and the audio signal to the display unit 609. The display unit 609 displays a video signal and outputs an audio signal from a speaker (not shown).

【0006】

FIG. 12 shows a physical channel setting method in the broadcast receiving device.

【0007】

In the initial state of this type of broadcast receiving device, a physical channel suitable for the place where it is installed is not set. Therefore, first, in order to identify the place where the broadcast receiving device is installed, the area identification information is manually input from the input unit 608 (S71). The area identification information includes, for example, a zip code, a telephone area code, and an area code. The broadcast receiving device acquires the corresponding physical channel setting information from the supplied area identification information (S72). The acquired physical channel setting information is stored in the storage unit 605 (S73). By this processing, for example, physical channel information such as NHK on channel 1 and NHK educational broadcast on channel 3 is stored.

【0008】

In the flowchart shown in FIG. 12, the operations after step S74 show the processing when the broadcast receiving device moves from the current area to another area and sets the same physical channel as described above. That is, the physical channel setting information stored in the storage unit 605 in advance is compared with the physical channel setting information after the movement (S74). As a result, if they are equal, the physical channel setting information is not changed (S75, S76), and if they are different, the physical channel setting information stored in the storage unit is changed to the new physical channel setting information (S77). ..

【0009】

[Problems to be Solved by the Invention]

By the way, in the above-mentioned conventional broadcast receiving device, the setting of physical channel information is a method of manually inputting a postal code, a telephone area code, an area code, and the like. Therefore, every time the broadcast receiving device leaves the service area of a specific broadcasting station and enters the service area of another broadcasting station, it is necessary to manually change the physical channel setting information. In particular, in recent years, this type of broadcast receiving device may be moved by a car or the like, and may frequently enter and exit the service area of a broadcasting station. In such a case, the work of changing the physical channel setting information becomes complicated, which is a problem.

【0010】

The present invention has been made to solve the above problems, and an object of the present invention is to provide a broadcast receiving device capable of automatically setting a channel.

【0011】

[Means for solving problems]

In order to solve the above problems, the broadcast receiving device of the present invention is based on a broadcast receiving unit that receives a broadcast wave, a detection unit that detects a position where the broadcast receiving unit exists, and a position detected by the detection unit. , It is provided with a setting unit for setting channel information corresponding to the service area of the broadcasting station in the broadcast receiving unit.

【0012】

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

【0013】

(First Embodiment) FIG. 1 shows an example in which the present invention is applied to a mobile terminal device such as a PDA (Personal Digital Assistant). The mobile terminal device 30 includes, for example, a mobile phone device 31 and a broadcast receiving device 32.

【0014】

The first control unit 220 constituting the mobile phone device 31 includes a mobile phone transmission / reception unit 200, a first storage unit 250, an input unit 260, a display unit 230, and area identification information / broadcast channel information (AID-CH). The conversion unit 310 is connected.

【0015】

The mobile phone transmitter / receiver 200 has an antenna 201 for a mobile phone. The mobile phone transmitter / receiver 200 communicates with the base station of the mobile phone via radio waves. The first control unit 220 can control the entire mobile phone device and instruct the display of, for example, a message, a warning, or an error of an application program. The first storage unit 250 stores application programs and databases of mobile phone devices, and also stores information necessary for signal processing. The display unit 230 displays a telephone number, an email, a message, a warning, or an error in the mobile phone device. Further, the display unit 230 displays a video signal supplied from the broadcast receiving device 32. The input unit 260 is composed of, for example, a numeric keypad or the like, and is used for inputting operation instructions and data to an application program by a user.

【0016】

On the other hand, in the broadcast receiving device 32, the second control unit 320 includes the area identification information / broadcast channel information (AID / CH) conversion unit 310, the broadcast receiving unit 300, the second storage unit 330, and the display unit 230. And the input unit 260 are connected.

【0017】

The broadcast receiving unit 300 has the same configuration as the broadcast receiving unit 600 shown in FIG. 11, and includes an antenna 601, a channel selection unit 602, a demodulation unit 603, a multiplex separation unit 604, and a decoding unit 605. The AID / CH conversion unit 310 converts the area identification information acquired via the mobile phone transmission / reception unit 200 into the physical channel information of the broadcasting station group. The second storage unit 330 stores the converted physical channel information of the broadcasting station group, and also stores the application program of the broadcasting receiving device 32 and the information necessary for signal processing. The second control unit 320 controls the entire broadcast receiving device 32.

【0018】

FIG. 2 shows an example of the AID / CH conversion unit 310. The AID / CH conversion unit 310 is composed of, for example, a read-only memory (ROM) or a rewritable non-volatile memory such as EEPROM. The physical channel information of the broadcasting station group is stored in this memory 311 corresponding to the area identification information, and it is possible to read out the physical channel information of the corresponding broadcasting station group based on the area identification information. ..

【0019】

The operation of the mobile terminal device 30 will be described with reference to FIGS. 3 and 4.

【0020】

FIG. 3 is a diagram illustrating the operation of the mobile phone device 31 and the broadcast receiving device 32. In FIG. 3, for example, mobile phone base stations 11, 12, and 13 are provided corresponding to mobile phone service areas 1, 2, and 3. In a normal mobile phone system, there are many service areas like a mesh, and each service area has many base stations. In this example, for convenience of explanation, each service area has one base station.

【0021】

The mobile terminal device 30 can move within the service areas 1, 2, and 3 of the base stations 11, 12, and 13, and receives the area identification information from the base station of the service area when entering each service area. .. For example, when the mobile terminal device 30 enters the service area 3 of the base station 13, the mobile terminal device 30 receives the area identification information set in the base station 13.

【0022】

Further, as shown by arrows A or B in FIG. 3, when the mobile terminal device 30 enters the service area 1 of the base station 11 or the service area 2 of the base station 12 from the service area 3 of the base station 13, the mobile terminal The device 30 receives the area identification information set in the base station 11. As described above, when the service area changes as the mobile terminal device 30 moves, the received area identification information also changes. The mobile phone device 31 recognizes the service area using this area identification information, registers the mobile station number in the base station, and performs a calling operation.

【0023】

There is a service area of the terrestrial broadcasting station group corresponding to the service area of the base station of the mobile phone. Figure 3 illustrates the service areas of broadcaster group A and broadcaster group B. Here, a broadcasting station group is a collection of physical channels of broadcasting stations that can be received within the service area, and one service area has at least one VHF broadcasting station or UHF station. For example, in the case of the Kanto region, VHF stations such as NHK, NHK Education, NTV, TBS, and Fuji TV (all are trademarks), and UHF stations are included. As shown by the arrow A in FIG. 3, when the mobile terminal device 30 moves from the service area 3 to the service area 1 of the base station 11, the service area of the broadcasting station also changes. Therefore, it is necessary to change the setting of the physical channel in the broadcast receiving unit 300. Further, as shown by arrow B in FIG. 3, when the service area 3 is moved to the service area 2 of the base station 12, the service area of the broadcasting station does not change. Therefore, it is not necessary to change the setting of the physical channel in the broadcast receiving unit 300.

【0024】

Next, the operation of the mobile terminal device 30 will be further described with reference to FIG.

【0025】

The mobile terminal device 30 receives the area identification information at predetermined time intervals by the mobile phone transmission / reception unit 200 (S11). The operation of receiving the area identification information is a well-known mobile phone function originally possessed by the mobile phone transmission / reception unit 200, and is usually executed during the standby operation. By receiving the area identification information, the mobile phone transmitter / receiver 200 recognizes the service area of the base station and registers the mobile station number in the base station.

【0026】

When the mobile phone transmission / reception unit 200 receives the area identification information, the area identification information is supplied from the mobile phone transmission / reception unit 200 to the first control unit 220. The first control unit 220 compares the area identification information supplied from the mobile phone transmission / reception unit 200 with the area identification information registered in advance in the first storage unit 250 (S12, S13). As a result, when they match, that is, when the same area identification information as the previous time is received, the first control unit 220 supplies the match signal to the AID / CH conversion unit 310. The AID / CH conversion unit 310 does not change the physical channel according to the matching signal. Therefore, the second control unit 320 does not change the physical channel setting of the broadcast reception unit 300 due to the non-conversion operation of the AID / CH conversion unit 310 (S14, S15).

【0027】

On the other hand, as a result of comparing the two area identification information in step S13, if they do not match, the first control unit 220 supplies new area identification information to the first storage unit 250, and the area identification information Update (S16). At the same time, the first control unit 220 outputs the mismatch signal and new area identification information to the AID / CH conversion unit 310. The AID / CH conversion unit 310 changes the physical channel information of the broadcasting station group according to the new area identification information. That is, the broadcast channel information corresponding to the newly supplied area identification information is read from the memory (S17). The second control unit 320 stores the physical channel information of the new broadcasting group supplied from the AID / CH conversion unit 310 in the second storage unit 330 (S18).

【0028】

After that, the second control unit 320 determines whether to change the setting of the broadcast reception unit 300 (S19). That is, the second control unit 320 determines whether or not the area identification information has been changed and the broadcast channel information has changed. As a result, when both change (when the mobile terminal device 30 moves in the direction of the arrow indicated by A in FIG. 3), the second control unit 320 changes the physical channel information of the broadcasting station group of the broadcast receiving unit 300. Will be (S20). Further, as a result of the above determination, if the broadcast channel information does not change (when the mobile terminal device 30 moves in the direction of the arrow shown by B in FIG. 3), the physical channel information of the broadcast station group of the broadcast receiver 300 is not changed (the physical channel information of the broadcast station group of the broadcast receiver 300 is not changed). S15).

【0029】

The second control unit 320 is, for example, when the power of the mobile terminal device 30 is turned on, or when the power of the mobile terminal device 30 is turned on and the area identification information is changed during movement, in step S19. In the judgment, for example, it is determined as YES.

【0030】

For example, there are two possible ways to set the channel for the numeric keypad that constitutes the input unit 260. The first method assigns the physical channels to the lowest number on the numeric keypad in ascending order of frequency. In this case, when the service area of the broadcasting station changes, the relationship between the numeric keypad number as the channel selection means and the physical channel changes. On the other hand, the second is to set the physical channel of the broadcasting station broadcasting the same program and the numeric keypad number in different service areas without changing them. Since the operation after setting the physical channel is the same as the process described with reference to FIG. 11, the description thereof will be omitted.

【0031】

According to the first embodiment, the mobile terminal device 30 has a mobile phone device 31 and a broadcast receiving device 32, and when the acquired area identification information is changed by the mobile phone device 31, AID / CH conversion is performed. The unit 310 generates the physical channel information of the broadcasting station corresponding to the new area identification information. Therefore, the physical channel information of the broadcast receiving unit 300 can be automatically changed by using the generated physical channel information. Therefore, even when the service area of the broadcasting station changes frequently, there is an advantage that the complicated change work as in the conventional case is not required.

【0032】

(Second Embodiment) FIG. 5 shows a second embodiment of the present invention, and the same parts as those of the first embodiment are designated by the same reference numerals.

【0033】

In the first embodiment, it is necessary that the mobile terminal device 30 does not know where to move and can receive the broadcast no matter where it moves. Therefore, the AID / CH conversion unit 310 needs to store all the area identification information and the broadcast channel information. Therefore, it requires a memory 311 having a large storage capacity. On the other hand, the second embodiment makes it possible to reduce the storage capacity of the memory.

【0034】

That is, as shown in FIG. 5, the host computer (server) 420 is connected to the base station 400 constituting the mobile phone system via the public telephone line network 410. For example, a hard disk device 430 is connected to the host computer 420. A database is stored in the hard disk device 430. This database stores all the area identification information and broadcast channel information as shown in FIG. 2, for example, and also stores application programs and various databases.

【0035】

The operation of the apparatus shown in FIG. 5 will be described with reference to FIG.

【0036】

For example, the mobile terminal device 30 on the move receives the area identification information from the base station 400 via the mobile phone transmission / reception unit 200 (S21). The first control unit 220 compares the received area identification information with the area identification information stored in the first storage unit 250 (S22, S23). As a result, when these match, the physical channel information of the broadcast receiving unit 300 is not changed as in the first embodiment (S24, S25).

【0037】

On the other hand, if there is a discrepancy as a result of the comparison, the new area identification information is supplied to the first storage unit 250, and the area identification information is updated (S26). At the same time, the new area identification information is supplied to the AID / CH conversion unit 310. The AID / CH conversion unit 310 searches for whether or not the physical channel information of the broadcasting station group corresponding to the supplied area identification information exists in the memory (S27, S28). As a result, when there is physical channel information of the corresponding broadcasting station group, the physical channel information of the corresponding broadcasting station group is transmitted to the second storage unit via the second control unit 320 as in the first embodiment. It is stored in (S31, S32).

【0038】

As a result of the above comparison, if there is no physical channel information of the corresponding broadcasting station group, or if the mobile terminal device 30 does not have the physical channel information of the broadcasting station group corresponding to the area identification information from the beginning, the first control unit 220 causes the mobile phone transmitter / receiver 200 to perform dial-up processing (S29). That is, the mobile phone transmission / reception unit 200 sets a call channel between the mobile terminal device 30 and the host computer 420 via the base station 400 and the public telephone line network 410. In this state, the first control unit 220 transfers the area identification information stored in the hard disk device 430 and the physical channel information of the broadcasting station group corresponding to the area identification information to the mobile terminal device 30 via the host computer 420. Download (S30).

【0039】

The downloaded area identification information and the physical channel information of the broadcasting station group are stored in the first storage unit 250. The area identification information stored in the first storage unit 250 and the physical channel information of the broadcasting station group are read out by the first control unit 220 and supplied to the second control unit 320. After that, the same processing as in the first embodiment is performed (S31 to S34, S25).

【0040】

According to the second embodiment, the broadcast channel information corresponding to all the area identification information is stored in the database of the hard disk device 430 connected to the host computer 420, and the area identification information is stored in the AID / CH conversion unit 310. If there is no corresponding broadcast channel information, the database can be accessed using the mobile phone function, and the physical channel information of the broadcasting station group corresponding to the area identification information can be downloaded. Therefore, the AID / CH conversion unit 310 does not need to store the broadcast channel information corresponding to all the area identification information. Therefore, the storage capacity of the memory can be reduced.

【0041】

Even if the service area described in the first embodiment changes in the database, for example, a ten-key number as a channel selection means of the mobile terminal device 30 and a program having the same contents in each service area are always broadcast. Information for setting the physical channel of a broadcasting station may be stored, and this information may be downloaded together with the physical channel information of the broadcasting station group.

【0042】

Further, it is more convenient to store incidental information such as program information and advertisement information in the broadcasting station in the area in the database so that the incidental information can also be downloaded. In this case, for example, when the power of the broadcast receiving device 32 is turned on, the acquired program information and advertisement information can be displayed on the display unit 230 and presented to the viewer. Further, the display of the incidental information can be displayed when the viewer specifies the display, or can be automatically displayed when the reception state of the broadcast wave deteriorates.

【0043】

(Third Embodiment) FIG. 7 shows a third embodiment of the present invention, and shows an example in which the present invention is applied to, for example, a car navigation system. In the third embodiment, the same parts as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

【0044】

In FIG. 7, the car navigation system 33 includes a GPS (Global Positioning Systems) antenna 501, a GPS receiver 500, a current position detection unit 510, a current position information / broadcast channel information (PP / CH) conversion unit 530, and a third. It has a storage unit 550.

【0045】

The GPS receiving unit 500 detects a position information signal from the GPS signal received by the GPS antenna 501. That is, the GPS receiver 500 receives signals from a plurality of GPS satellites and measures the absolute position of the vehicle. The current position detection unit 510 includes a speed sensor for measuring the relative position of the vehicle, a direction sensor for measuring the direction, and the like. The current position information / broadcast channel information (PP / CH) conversion unit 530 converts the current position information into the physical channel information of the broadcasting station group. Like the AID / CH conversion unit 310, the PP / CH conversion unit 530 is composed of, for example, ROM or EEPROM, and stores the physical channel information of the broadcasting station group corresponding to the current position information. The third storage unit 550 stores map information, destination information, travel route, current position information, and the like.

【0046】

Next, the operation of the part shown in FIG. 7 will be described with reference to FIG.

【0047】

The GPS antenna 501 and the GPS unit 500 receive GPS signals including position information transmitted from GPS satellites. This received GPS signal is supplied to the first control unit 220. The current position detection unit 510 calculates information indicating the current position of the car navigation system 33 based on the output signals of the speed sensor and the direction sensor and the GPS signal supplied from the first control unit 220 (S41). The calculated current position information is supplied to the first control circuit 220. The first control unit 220 reads out the previous current position information in which the supplied current position information is stored in the first storage unit 250 (S42). The read previous current position information is compared with the calculated current position information (S43). As a result, when they match, the first control unit 220 supplies the matching signal to the PP / CH conversion unit 530. Therefore, as in the first and second embodiments, the physical channel information of the broadcast receiving unit 300 is not changed (S44, S45).

【0048】

On the other hand, if the result of the comparison is inconsistent, the calculated new current position information is supplied to the third storage unit 550, and the current position information is updated (S46). At the same time, the first control unit 220 supplies the mismatch signal and the new current position information to the PP / CH conversion unit 530. The PP / CH conversion unit 530 changes the physical channel information of the broadcasting station group according to the new current position information. That is, the broadcast channel information corresponding to the newly supplied current position information is read from the memory (S47). The second control unit 320 stores the physical channel information of the new broadcasting group supplied from the PP / CH conversion unit 530 in the second storage unit 330 (S48). Hereinafter, the physical channel information of the broadcast receiving unit 300 is changed by the same processing as in the first embodiment (S49, S50, S45).

【0049】

According to the third embodiment, the car navigation system 33 detects the current position information, and the physical channel information of the broadcasting station group can be changed based on the detected current position information. Therefore, when the broadcast receiving device 32 moves between the service areas of the broadcasting station group, the physical channel information of the broadcasting receiving device 32 is automatically changed, which has the advantages of complicated change work and unnecessary change. There is.

【0050】

In addition, since the current position information is detected using GPS signals, there is an advantage that the physical channel information of the broadcasting station group can be automatically changed even in areas other than the service area of the mobile phone.

【0051】

(Fourth Embodiment) FIG. 9 shows a fourth embodiment of the present invention. The fourth embodiment is a combination of the second embodiment and the third embodiment, and the same parts as those of the second and third embodiments are designated by the same reference numerals.

【0052】

In FIG. 9, a mobile phone transmission / reception unit 200 is connected to the first control unit 220. In the database of the hard disk device 430, for example, broadcast channel information indicating the physical address information of the broadcast song group corresponding to all the current position information is stored.

【0053】

The operation of the part shown in FIG. 9 will be described with reference to FIG. In FIG. 9, the same parts as those in FIG. 8 are designated by the same reference numerals.

【0054】

In the fourth embodiment, the operation when the current position information calculated by using the GPS signal and the output signal of the speed sensor or the direction sensor and the current position information stored in the third storage unit 550 are equal to each other is It is the same as the third embodiment (S41 to S45).

【0055】

On the other hand, as a result of comparison in step S43, if the calculated new current position information and the current position information stored in the third storage unit 550 do not match, the new current position information is the third storage unit. It is supplied to the 550 and the current location information is updated (S46). After that, the PP / CH conversion unit 530 is accessed, and it is detected whether or not there is the calculated current position information in the memory (S51, S52). As a result, when the PP / CH conversion unit 530 has the same current position information as the new current position information, the physical channel information of the broadcast receiving unit 300 is changed by the same operation as in the third embodiment. (S48 ~ S50).

【0056】

On the other hand, when the PP / CH conversion unit 530 does not have the same current position information as the new current position information, the first control unit 220 activates the mobile phone transmission / reception unit 200 to access the external database. (S53). That is, the mobile phone transmission / reception unit 200 sets a call channel between the mobile terminal device 30 and the host computer 420 via the base station 400 and the public telephone line network 410. In this state, the first control unit 220 downloads the current position information stored in the hard disk device 430 and the physical channel information of the broadcasting station group corresponding to the current position information via the computer 420 (S54). ).

【0057】

The downloaded current location information and the physical channel information of the broadcasting station group are stored in the third storage unit 550. The current position information stored in the third storage unit 550 and the physical channel information of the broadcasting station group are read out by the first control unit 220 and supplied to the second control unit 320. Hereinafter, the physical channel information of the broadcast receiving unit 300 is changed by the same processing as in the third embodiment (S47 to S50, S45).

【0058】

According to the fourth embodiment, when the newly acquired current position information is not in the PP / CH conversion unit 530, the mobile phone transmission / reception unit 200 is used to access the database connected to the host computer 420. The current location information and the physical channel information of the broadcasting station group are downloaded from this database. Therefore, since the PP / CH conversion unit 530 only needs to have a capacity capable of storing the minimum necessary current position information and the physical channel information of the broadcasting station group, the storage capacity of the memory can be reduced. ..

【0059】

In addition, it goes without saying that various modifications can be carried out without changing the gist of the present invention.

【0060】
