Next, viewing control processing executed by the television receiver 1 of the television system 100 will be described with reference to FIGS.
5 and 6 are flowcharts showing an example of the operation related to the viewing control process.
The viewing control process is a control process executed by the television receiver 1 under the control of the central control unit 109 when the user views the program content displayed on the television receiver 1.

As shown in FIG. 5, first, the communication control unit 107 searches for all portable terminals 2 that can be connected to the first communication network N1 (for example, a wireless PAN realized by a short-range wireless communication standard such as Zigbee). And the 1st communication network N1 is established between the 1st communication control parts 202 of the portable terminal 2 which can be connected (step S1).
Subsequently, the central control unit 109 determines whether a channel switching instruction related to the program content viewed by the user has been input based on a predetermined operation of the operation input unit 108 by the user (step S2). If it is determined that a channel switching instruction has been input (step S2; YES), the central control unit 109 switches the channel selectively received by the tuner 101 in accordance with the channel switching instruction, and corresponds to the channel. A television broadcast signal (program content) existing at a specific frequency is received by the tuner 101 (step S3).

The tuner 101 modulates the received television broadcast signal and outputs an intermediate frequency signal to the signal demodulator 102. The signal demodulator 102 outputs the intermediate frequency signal output from the tuner 101 and input thereto. Predetermined processing such as digital demodulation and error correction is performed, and the transport stream is output to the output control unit 103 (step S4). Also, if it is determined in step S2 that a channel switching instruction has not been input (step S2; NO), the central control unit 109 shifts the process to step S4.
Subsequently, the output control unit 103 decodes the transport stream input from the signal demodulating unit 102 into a plurality of streams such as video data, audio data, program identification information (PSI), and program arrangement information (SI). Separate (step S5). Then, the output control unit 103 performs predetermined processing such as decoding on the separated video data, and displays the main video on the entire display screen of the display unit 104a according to the video data (step S6). Further, the output control unit 103 performs predetermined processing such as decoding on the separated audio data and outputs it to the audio output unit 104 b of the output unit 104.

Next, the central control unit 109 determines whether or not it is a mode for displaying program-related information (step S7).
Here, whether or not it is a mode for displaying program-related information is determined based on whether or not the mode is designated in advance based on a predetermined operation of the operation input unit 108 by the user, for example. The determination is made according to whether or not an instruction to display program related information is input from the portable terminal 2 connected via the first communication network N1.

If it is determined in step S7 that the mode is a mode for displaying program-related information (step S7; YES), the central control unit 109, as shown in FIG. Mode for displaying the title of the currently viewed program, broadcast station, genre, broadcast time, performer, program content, etc.) other than the display screen (self-screen) of the display unit 104a of the television receiver 1 It is determined whether or not (step S8).
Here, the determination as to whether or not the mode is a mode for displaying program additional information on a screen other than the own screen depends on, for example, whether or not the mode is designated in advance based on a predetermined operation of the operation input unit 108 by the user. Or whether there is a mobile terminal 2 connected via the first communication network N1.

If it is determined in step S8 that the mode is not a mode for displaying program additional information other than the own screen (step S8; NO), that is, the program additional information is displayed on the display screen of the display unit 104a of the television receiver 1. Therefore, the output control unit 103 reduces the size of the main video related to the video data to a predetermined ratio with respect to the entire display screen and displays it at a predetermined position, and generates display data based on the program related information. Based on the display data, various program related information is displayed in an area (part of the own screen) other than the area where the main video is displayed on the display screen (step S9).
On the other hand, if it is determined that the mode is a mode for displaying program additional information on a screen other than the own screen (step S8; YES), that is, the mode is a mode for transmitting program-related information to the mobile terminal 2, the central control unit 109 Then, it is determined whether or not it is a mode for transmitting the program additional information to the portable terminal 2 (step S10).

If it is determined in step S10 that the mode is the mode for transmitting the program additional information (step S10; YES), the central control unit 109 sends the information generation unit 106 based on the EPG information G stored in the memory 105. After the program additional information related to the currently viewed program is generated, it is determined whether or not the content of the program additional information has changed since the previous transmission (step S11). The program additional information may be stored in the memory 105 each time it is generated, for example, and the central control unit 109 may acquire the program additional information transmitted last time.
Here, if it is determined that the content of the program additional information has not changed since the previous transmission (step S11; NO), the central control unit 109 determines a predetermined time from the previous transmission (transmission timing) of the program additional information. It is determined whether or not elapses (step S12). For example, the transmission timing of the program additional information may be stored in the memory 105 every time it is transmitted, and the central control unit 109 may acquire the previous transmission timing. .

If it is determined in step S12 that a predetermined time has elapsed since the previous transmission timing of the program additional information (step S12; YES), the communication control unit 107 transmits the program additional information to the mobile terminal 2 in the first communication. Transmission is performed via the network N1 (step S13).
If it is determined in step S11 that the content of the program additional information has changed since the previous transmission (step S11; YES), the central control unit 109 shifts the process to step S13 to control communication. Unit 107 transmits the program additional information to mobile terminal 2 via first communication network N1 (step S13).

Thereafter, the central control unit 109 determines whether an instruction to turn off the power of the television receiver 1 is input based on a predetermined operation of the operation input unit 108 by the user (step S14).
Moreover, also when it determines with predetermined time not having passed since the last transmission timing of program additional information in step S12 (step S12; NO), the central control part 109 transfers a process to step S14. . In step S9, the output control unit 103 displays various program-related information in an area (part of the own screen) other than the area where the main video is displayed on the display screen, or in FIG. As shown, the central control unit 109 also shifts the process to step S14 when it is determined in step S7 that the mode is not a mode for displaying program-related information (step S7; NO).

When it is determined in step S14 that an instruction to turn off the power of the television receiver 1 is not input (step S14; NO), as shown in FIG. The process proceeds to step S2, and in the same manner as described above, it is determined whether or not a channel switching instruction related to the program content viewed by the user has been input (step S2).
On the other hand, if it is determined that an instruction to turn off the power of the television receiver 1 is input (step S14; YES), the central control unit 109 turns off the power of the television receiver 1. Then, the viewing control process is terminated.

On the other hand, if it is determined in step S10 that the mode is not a mode for transmitting program additional information (step S10; NO), that is, the mode is a mode for transmitting channel information to the mobile terminal 2, the central control unit 109 Based on the EPG information G stored in the memory 105, the information generation unit 106 generates channel information related to the currently viewed program, and then determines whether there is a channel change since the previous transmission. (Step S15). The channel information may be stored in the memory 105 each time it is generated, for example, and the central control unit 109 may acquire the channel information transmitted last time.
If it is determined that the channel has not changed since the previous transmission (step S15; NO), the central control unit 109 determines whether or not a predetermined time has elapsed since the previous transmission (transmission timing) of the channel information. Is determined (step S16). For example, the transmission timing of the channel information may be stored in the memory 105 every time it is transmitted, and the central control unit 109 may acquire the previous transmission timing.

If it is determined in step S16 that a predetermined time has elapsed since the previous transmission timing of the channel information (step S16; YES), the communication control unit 107 transmits the channel information to the mobile terminal 2 in the first communication network N1. (Step S17).
If it is determined in step S15 that there is a change in the content of the channel information from the previous transmission (step S15; YES), the central control unit 109 moves the process to step S17, and the communication control unit 107 transmits the channel information to the portable terminal 2 via the first communication network N1 (step S17).

Thereafter, the central control unit 109 shifts the processing to step S14 and determines whether or not an instruction to turn off the power of the television receiver 1 is input (step S14). Moreover, also when it determines with predetermined time not having passed since the last transmission timing of channel information in step S16 (step S16; NO), the central control part 109 transfers a process to step S14.
When it is determined in step S14 that an instruction to turn off the power of the television receiver 1 is input (step S14; YES), the central control unit 109 determines that the television receiver 1 The power is turned off to end the viewing control process.

Next, viewing control processing executed by the mobile terminal 2 of the television system 100 will be described with reference to FIG.

On the other hand, if it is determined in step S51 that the mode for viewing the television receiver 1 is selected (step S51; YES), the first communication control unit 202 determines the first communication network N1 (for example, Zigbee). All the television receivers 1 that can be connected to a wireless PAN or the like realized by a short-range wireless communication standard such as the first communication with the communication control unit 107 of the connectable television receiver 1 are searched. A network N1 is established (step S53).
Subsequently, the display control unit 205 causes the display unit 204 to display information (for example, various information such as manufacturer name and model) of all the television receivers 1 for which the first communication network N1 has been established (step S54). ).

Thereafter, the central control unit 208 accepts a selection instruction for any one of the television receivers 1 that receive the program related information, and determines whether or not the selection instruction is input (step S55).
Here, if it is determined that the selection instruction for any one of the television receivers 1 has not been input (step S55; NO), the central control unit 208 moves the process to step S54, and thereafter. Execute the process.
On the other hand, if it is determined that an instruction to select any one of the television receivers 1 has been input (step S55; YES), the first communication control unit 202 is transmitted from the selected television receiver 1. The program related information is received and it is determined whether or not the program related information is received (step S56). Even if it is determined in step S56 that program related information has not been received (step S56; NO), the determination in step S56 is sequentially performed with a predetermined interval until the time limit has elapsed.

If it is determined in step S56 that the program related information transmitted from the selected one television receiver 1 has been received (step S56; YES), the central control unit 208 determines that the received program related information is a program. It is determined whether it is additional information (step S57).
Here, if it is determined that it is not program additional information (step S57; NO), that is, since the program-related information is channel information, the second communication control unit 203 uses the second communication network N2 based on the channel information. The content information corresponding to the channel is acquired from the storage unit 302 of the server 3 (step S58).

  Subsequently, the display control unit 205 generates display data based on the content information acquired by the second communication control unit 203 and displays the content information in a predetermined area of the display screen based on the display data ( Step S59). Also, when it is determined in step S57 that the program additional information is included (step S57; YES), the central control unit 208 proceeds to step S59, and the display control unit 205 performs the first communication. Display data based on the program additional information received by the control unit 202 is generated, and various program additional information is displayed in a predetermined area of the display screen based on the display data (step S59).

Next, the central control unit 208 determines whether or not the content information received by the second communication control unit 203 includes address information (for example, a URI or URL) indicating the storage location of various types of content (for example, URI). Step S60).
Here, if it is determined that the address information is included (step S60; YES), the second communication control unit 203 accesses the content providing page on the Internet based on the address information, and the content providing page Various types of content provided in (1) are acquired (step S61). Then, the display control unit 205 generates display data for various contents acquired by the second communication control unit 203, and displays the various contents in a predetermined area of the display screen based on the display data (step S62). ).

Next, the central control unit 208 determines whether a switching instruction for any one of the television receivers 1 that receive program-related information is input based on a predetermined operation of the operation input unit 207 by the user ( Step S63). Also, when it is determined in step S60 that the address information is not included (step S60; NO), the central control unit 208 moves the process to step S63 and switches the television receiver 1. It is determined whether or not an instruction has been input (step S63).
Here, if it is determined that the switching instruction of the television receiver 1 has not been input (step S63; NO), the central control unit 208 performs the television based on a predetermined operation of the operation input unit 207 by the user. It is determined whether or not an instruction to turn off the power of the receiver 1 has been input (step S64).
On the other hand, when it is determined in step S63 that a switching instruction for the television receiver 1 has been input (step S63; YES), the central control unit 208 proceeds to step S55 to receive program-related information. A selection instruction for any one of the television receivers 1 is received, and it is determined whether or not the selection instruction is input (step S55).

If it is determined in step S64 that an instruction to turn off the power of the television receiver 1 has not been input (step S64; NO), the central control unit 208 proceeds to step S56. Similarly to the above, the first communication control unit 202 receives the program related information transmitted from the selected one television receiver 1 and determines whether or not the program related information is received (step). S56).
On the other hand, if it is determined that an instruction to turn off the power of the television receiver 1 is input (step S64; YES), the central control unit 208 turns off the power of the television receiver 1. Then, the viewing control process is terminated.

As described above, according to the television system 100 of the present embodiment, the television receiver 1 receives a broadcast signal including program content corresponding to at least one channel and program information of the program content, Based on the broadcast signal, one program content selected for viewing is displayed on the display unit 104a, and among the program information included in the broadcast signal, a program related to the program content displayed on the display unit 104a The related information is transmitted to the portable terminal 2 via the predetermined first communication network N1. The portable terminal 2 receives the program related information transmitted from the television receiver 1 and causes the display unit 204 to display the program related information.
Accordingly, when the viewer wants to confirm the program related information of the program content currently being viewed using the television receiver 1, the program related information is transmitted from the television receiver 1 to the portable terminal 2. When the viewer visually recognizes the display unit 204 of the mobile terminal 2, the viewer can confirm the program related information. Therefore, it is not necessary to reduce the main video displayed on the display screen of the television receiver 1 or display the program related information superimposed on the main video for displaying the program related information.
Thus, even when there are a plurality of viewers, desired information is individually provided to each viewer without affecting the main video displayed on the display screen of the television receiver 1. Can do.
In particular, even when display of program related information related to the program content being displayed on the television receiver 1 is prohibited on the display unit 104a, the program related information is transmitted via the predetermined first communication network N1. Can be transmitted to the mobile terminal 2 and displayed on the display unit 204 of the mobile terminal 2, so that the viewer who wants to view the main video of the program content displayed on the display screen of the television receiver 1 or the program Desired information can be individually provided to each viewer who wants to confirm program-related information related to the content.

In addition, the television receiver 1 is configured so that the output control unit 103 switches the channel corresponding to the program content displayed on the display unit 104a, changes the program content, or changes the predetermined time. Every time it passes or every time there is a transmission request from the mobile terminal 2 side, the program related information is transmitted to the mobile terminal 2, so it is possible to sufficiently ensure the provision timing of the program related information to the viewer, A television system that is easy to use for the viewer can be provided.
Further, when the television receiver 1 is connected to a plurality of portable terminals 2,..., Program related information is transmitted to all of the plurality of portable terminals 2,. On the other hand, program related information can be provided.
At this time, the display control unit 205 of each of the plurality of mobile terminals 2,... Switches whether to display the program related information received by each first communication control unit 202 based on a predetermined operation by the user. Therefore, the information can be individually provided only to the viewer who desires the program related information without affecting the main video displayed on the display screen of the television receiver 1.

  In addition, by designating one television receiver 1 that receives program-related information from among the plurality of television receivers 1... Based on a predetermined operation by the user, the television receiver from which program-related information is desired to be acquired. The viewer can select whether to acquire the program-related information related to the program content displayed on the device 1, that is, which television receiver 1. Thereby, even if there are a plurality of television receivers 1 that can be connected to one portable terminal 2 via the predetermined first communication network N1, a viewer who confirms the display contents of each television receiver 1 can surely Desired program related information can be acquired.

Furthermore, the mobile terminal 2 acquires content information related to the program content displayed on the display unit 104 a from the storage unit 302 of the server 3 by the output control unit 103 of the television receiver 1 based on the program related information. Can do. Specifically, the content information is acquired from the storage unit 302 of the server 3 based on instruction information (for example, channel information) that instructs content information included in the program-related information. More specifically, the storage unit 302 of the server 3 stores a plurality of content information corresponding to each of the plurality of program contents, and the mobile terminal 2 stores the content information based on the instruction information included in the program related information. The content information related to the program content displayed on the display unit 104 a is acquired from the plurality of pieces of content information stored in the unit 302 by the output control unit 103 of the television receiver 1. Then, the mobile terminal 2 causes the display control unit 205 to display the acquired content information.
Accordingly, even when various pieces of content information are not included in the program-related information acquired from the television receiver 1, various types of content information related to the desired program content can be acquired from the server 3 and viewed. Desired content information can be provided to the user.

  Even if the storage unit 302 of the server 3 stores address information indicating the storage location of the various contents in a predetermined third communication network (for example, the Internet) instead of the various contents, The terminal 2 acquires address information associated with the instruction information included in the program-related information from the server 3, and acquires content information by accessing a predetermined third communication network based on the address information. Therefore, the viewer can provide various content information related to the desired program content.
