[TV broadcasting viewing function]
The mobile phone according to such an embodiment has a total of five televisions including a “background recording function”, a “multi-program display function”, a “high-speed program switching function”, a “tunerless function”, and a “shared reception function”. It has a broadcast viewing function.

  When the television broadcast viewing function is executed, the control unit 17 of each mobile phone, based on the TV control program and the short-range wireless communication program stored in the memory 16, allows each mobile phone capable of short-range wireless communication. “Tuning information” including information such as the channel currently being received, the reception level, and the recording status is transmitted to and received from the telephone. Then, based on the tuning information, the channel to be viewed, and the channel to be recorded, a channel to be selected by the mobile phone is determined according to the “tuning determination routine” shown in the flowchart of FIG.

  That is, when the television broadcast viewing function is executed, the control unit 17 of each mobile phone determines whether or not there is a program designated to be recorded by the user in step S1 of the flowchart of FIG. If there is a program designated for recording by the user, in step S4, the TV control unit 12 is subjected to channel selection control so that the channel of the program designated for recording by the user is selected.

  On the other hand, when there is no program designated to be recorded by the user, the control unit 17 advances the process to step S2, and performs the above-mentioned “tuning information” in which short-range wireless communication is performed with another mobile phone. Based on the above, it is determined whether or not the channel of the program to be viewed is being selected in any other mobile phone in short-range wireless communication. If the channel of the program to be viewed is not selected on any other mobile phone that is performing short-range wireless communication, the control unit 17 advances the process to step S5 to view the view designated by the user. The TV control unit 12 is controlled to select the channel of the program to be selected.

  On the other hand, when the channel of the program to be viewed is selected in any other mobile phone that is in short-range wireless communication, the control unit 17 advances the process to step S3, and between the other mobile phones. Based on the above-mentioned “tuning information” in which short-range wireless communication is performed, the reception level and remaining battery level of other mobile phones are detected, and these are compared with the reception level and remaining battery level of the terminal itself. If the reception level of the own terminal is better than the reception level of other mobile phones and / or the remaining battery level of the own terminal is higher than the remaining battery level of other mobile phones, the channel to be viewed Therefore, the control unit 17 advances the processing to step S6, and controls the TV control unit 12 to select a channel to be viewed.

  On the other hand, the reception level of the own terminal is lower than the reception level of other mobile phones, and / or the battery level of the own terminal is less than the remaining battery level of other mobile phones. In this case, since it is better to select the channel to be viewed with another mobile phone, the control unit 17 advances the processing to step S7. When the “high-speed program switching function” is set, the control unit 17 selects the TV control unit 12 so as to select “peripheral channels” of the channel to be viewed in step S7. Control.

Based on such a tuning determination routine, the control unit 17 determines a channel to be selected by the own terminal, and then performs recording control and / or viewing control for each function described below.

[Background recording function]
FIG. 5 is a schematic diagram of the background recording function, and FIG. 6 is a sequence diagram when the background recording function is executed. When executing this background recording function, the control unit 17 of the first mobile phone 31 exchanges tuning information with the second mobile phone 32 through the short-range wireless communication unit 14 and The channel for recording (in this example, 2 channels) and the channel for viewing (in this example, 1 channel) designated by the above are respectively recognized. In addition, the control unit 17 of the second mobile phone 32 recognizes the channel to be viewed (in this example, 2 channels).

  Next, the control unit 17 of each of the mobile phones 31 and 32 determines a channel to be selected based on the above “tuning determination routine”. In this case, since one channel is recorded on the first mobile phone 31 side, the control unit 17 selects a channel for performing the recording as described in step S1 and step S4 of the flowchart of FIG. Thus, the TV control unit 12 is subjected to channel selection control. Further, since the first mobile phone 31 side views two channels, the control unit 17 of the second mobile phone 32 performs the viewing 2 as described in step S2 and step S5 of the flowchart of FIG. The TV control unit 12 is controlled to select a channel, and the short-range wireless communication unit 14 is controlled so that the stream data of the two channels is used as the first mobile phone 31.

  The control unit 17 of the first mobile phone 31 controls the recording of the large-capacity memory 15 so as to perform recording of one channel selected by the own terminal, and is transmitted from the second mobile phone 32 by short-range wireless transmission. Further, the output of the stream data of two channels is controlled via the display unit 5 and the speaker unit 3. The control unit 17 of the second mobile phone 32 controls the output of the two-channel stream data selected by the own terminal via the display unit 5 and the speaker unit 3.

  As a result, even if the first mobile phone 31 has only one tuner function, the second mobile phone 32 selects a channel while recording one channel on the first mobile phone 31 side. The two-channel television broadcast can be viewed (= the two channels can be viewed in the foreground while receiving and recording one channel in the background).

In this example, the first portable terminal device 31 performs recording of one channel selected by the own terminal and views two channels transmitted from the second portable terminal device 32 by short-range wireless transmission. However, on the contrary, it is also possible to record one channel that is transmitted from the second mobile terminal device 32 by short-range wireless transmission and view two channels selected by the terminal itself.

[Multi program display function]
Next, FIG. 7 shows a schematic diagram of the multi-program display function, and FIG. 8 shows a sequence diagram when the multi-program display function is executed. When executing this multi-program display function, the control unit 17 of the first mobile phone 31 exchanges tuning information between the second to fourth mobile phones 32 to 34 via the short-range wireless communication unit 14. Do. And the control part 17 of each mobile telephone 31-34 determines the channel selected by a self terminal based on this tuning information.

  Next, for example, channel 1 is selected by the first mobile phone 31, channel 2 is selected by the second mobile phone 32, channel 3 is selected by the third mobile phone 33, and the fourth mobile phone is selected. Assuming that the channel 34 is selected by the telephone 34, the control unit 17 of each of the mobile phones 31 to 34 transmits the stream data of the channel selected by the own terminal to another mobile phone via the short-range wireless communication unit 14. Send to phone.

  The control unit 17 of the first mobile phone 31 decodes the stream data of one channel selected by its own terminal via the TV control unit 12 and also from the second to fourth mobile phones 32 to 34. The 2-channel, 3-channel, and 4-channel stream data received via the distance wireless communication unit 14 is decoded via the TV control unit 12. Then, the display area of the display unit 5 is divided into four equal parts, and stream data of 1 channel to 4 channels are output controlled to each of the divided display areas.

  As a result, even if the first mobile phone 31 has only one tuner function, the other mobile phones 32 to 34 can select the channel other than the one channel selected on the first mobile phone 31 side. It is possible to view the broadcasted 2-channel to 4-channel television broadcasts. When displaying stream data of a plurality of channels in this way, the stream data of each channel may be down-decoded.

Further, like the third mobile phone 33 shown in FIGS. 7 and 8, the own terminal selects 3 channels, and the second mobile phone 32 and the fourth mobile phone 34 respectively select 2 channels and 4 respectively. The channel stream data may be received by short-range wireless communication, and the stream data of channels 2 to 4 may be recorded in the large capacity memory 15.

[High-speed program switching function]
Next, FIG. 9 shows a schematic diagram of the high-speed program switching function, and FIG. 10 shows a sequence diagram when the high-speed program switching function is executed. When this high-speed program switching function is executed, each control unit 17 of the first mobile phone 31 to the third mobile phone 33 exchanges tuning information with other mobile phones via the short-range wireless communication unit 14. Exchange. Then, the control unit 17 of each of the mobile phones 31 to 33 recognizes the viewing channel designated by the user and determines the channel to be selected by the own terminal based on the tuning information.

  For example, when watching a two-channel television broadcast on each of the mobile phones 31 to 33, the control unit 17 of the first mobile phone 31 controls the TV control unit 12 to select these two channels, The 2-channel stream data is transmitted to the second and third mobile phones 32 and 33 via the short-range wireless communication unit 14.

  The control unit 17 of the second mobile phone 32 controls the output of the 2-channel stream data received from the first mobile phone 31 via the short-range wireless communication via the display unit 5 and the speaker unit 3 and the periphery of the two channels. For example, the TV control unit 12 is controlled so as to select one channel, which is one of the channels. The 1-channel stream data is transmitted to the first and third mobile phones 31 and 33 via the short-range wireless communication unit 14.

  Similarly, the control unit 17 of the third mobile phone 33 controls the output of the 2-channel stream data received from the first mobile phone 31 via the short-range wireless communication via the display unit 5 and the speaker unit 3, and The TV control unit 12 is controlled to select, for example, three channels which are peripheral channels. The three-channel stream data is transmitted to the first and third mobile phones 31 and 33 via the short-range wireless communication unit 14.

  The control unit 17 of the first mobile phone 31 decodes the 2-channel stream data selected by the own terminal and performs output control via the display unit 5 and the speaker unit 3, as well as the second and third channels. The 1-channel and 3-channel stream data transmitted from the mobile telephones 32 and 33 in the short distance are respectively decoded and stored in the large-capacity memory 15.

  In addition, the control unit 17 of the second mobile phone 32 decodes the 2-channel stream data received from the first mobile phone 31 by short-distance wireless transmission and controls the output via the display unit 5 and the speaker unit 3. The 1-channel stream data selected by the own terminal and the 3-channel stream data received from the third mobile phone 33 by short-distance radio are respectively decoded and stored in the large-capacity memory 15.

  Similarly, the control unit 17 of the third mobile phone 33 decodes the 2-channel stream data received from the first mobile phone 31 by short-distance wireless transmission and controls the output via the display unit 5 and the speaker unit 3. At the same time, the stream data of 3 channels selected by the own terminal and the stream data of 1 channel received by the short-distance wireless transmission from the second mobile phone 32 are respectively decoded and stored in the large-capacity memory 15.

  Thereby, in each of the mobile phones 31 to 33, the stream data of 1 channel and 3 channels, which are the peripheral channels of the currently viewed 2 channels, are decoded in advance and stored in the large capacity memory 15. Therefore, when a channel switching instruction operation is performed by the user, the stream data of the channel corresponding to the switching instruction operation is read from the large-capacity memory 15 and output via the display unit 5 and the speaker unit 3. The channel (program) can be switched at high speed.

  In the case of this example, when the same two channels are viewed on each of the mobile phones 31 to 33, the first mobile phone 31 selects the two channels and the other second and third mobile phones 32 and 33 are selected. Then, it was decided that the 1 channel and the 3 channel, which are the peripheral channels of the 2 channels to be viewed, are selected, respectively, but the second and third mobile phones 32 and 33 have a channel around the channel to be viewed. In addition to the channel, a channel of a broadcasting station that broadcasts a broadcast program with a high audience rating may be selected.

Further, when the stream data received from another mobile phone via the short-range wireless communication unit 14 is decoded data (see FIG. 3), the above-described decoding processes can be made unnecessary.

[Tunerless function]
Next, FIG. 11 shows a schematic diagram of the tunerless function, and FIG. 12 shows a sequence diagram when the tunerless function is executed. Note that the first mobile phone 31 shown in FIGS. 11 and 12 does not have a tuner function, and the second mobile phone 32 has a tuner function.

  In this case, the first and second mobile phones 31 and 32 exchange the tuning information via the short-range wireless communication unit 14. Then, the control unit 17 of the second mobile phone 32 controls the output of, for example, 1-channel stream data selected by the own terminal via the display unit 5 and the speaker unit 3 and the 1-channel stream data. Then, short-range wireless transmission is performed to the first mobile phone 31 side via the short-range wireless communication unit 14.

  The control unit 17 of the first mobile phone 31 receives the stream data of one channel transmitted from the second mobile phone 32 side via the short-range wireless communication via the short-range wireless communication unit 14, and displays the stream data on the display unit. 5 and output control through the speaker unit 3. Thereby, even when the first mobile phone 31 does not have a tuner function, the television broadcast can be viewed.

  In this example, the first mobile phone 31 does not have the tuner function. However, even if the tuner function of the first mobile phone 31 is turned off, the second mobile phone 31 does not have the tuner function. Based on the stream data transmitted from the mobile phone 32 at a short distance, the television broadcast can be viewed in the same manner as described above.

Also, since the stream data of the channel selected by another mobile phone can be short-range wirelessly communicated, it is possible to select stream data with high reception strength from one's own mobile phone and another mobile phone, By transmitting the stream data of the channel selected by one mobile phone to the other mobile phones by short-range wireless transmission, the other mobile phones can be operated with low power consumption.

[Shared reception function]
Next, FIG. 13 shows a schematic diagram of the shared reception function, and FIG. 14 shows a sequence diagram when the shared reception function is executed. As shown in FIG. 13, for example, when a 5-channel television broadcast is composed of stream data of a total of three segments from the first to the third, a mobile phone having only one antenna and a tuner function is provided. All the stream data of the three segments cannot be received. For this reason, each control part 17 of the 1st-3rd mobile telephones 31-33 determines the segment to select a channel by an own terminal by exchanging tuning information via the short-range wireless communication part 14, respectively. .

  Thereby, for example, the control unit 17 of the first mobile phone 31 selects the stream data of the first segment of the five channels via the TV control unit 12 and selects the stream data of the first segment at a short distance. Short-distance wireless transmission is performed to the second and third mobile phones 32 and 33 via the wireless communication unit 14.

  Similarly, the control unit 17 of the second mobile phone 32 selects the stream data of the second segment of the five channels via the TV control unit 12, and uses the stream data of the second segment as a short-range wireless communication. Short-distance wireless transmission is performed to the first and third mobile phones 31 and 33 via the communication unit 14.

  Similarly, the control unit 17 of the third mobile phone 33 selects the stream data of the third segment of the five channels via the TV control unit 12, and uses the short-distance wireless communication for the stream data of the third segment. Short-distance wireless transmission is performed to the first and second mobile phones 31 and 32 via the unit 14.

As a result, even when each mobile phone 31 to 33 is provided with only one antenna and tuner function, it is possible to receive and view all the stream data of a plurality of segments forming a television broadcast of one channel. can do.

[Operation when the TV broadcast viewing function is executed]
Next, the flowchart of FIG. 15 shows the flow of the operation of the control unit 17 when such a television broadcast viewing function is executed. This flowchart is started by the control unit 17 based on the TV control program stored in the memory 16 when the execution of the television broadcast viewing function is designated by the user via the operation unit 6.

  First, in step S11, the control unit 17 controls the short-range wireless communication unit 14 to exchange “tuning information” with another mobile phone, and proceeds to step S12.

  In step S12, the control unit 17 recognizes a channel (program) that can be viewed and recorded based on the tuning information of the terminal itself and the tuning information received from another mobile phone, and the process proceeds to step S13.

  In step S13, the control unit 17 recognizes the presence / absence of a channel designated for recording according to the presence / absence of an input operation from the user, and advances the processing to step S14. In step S14, the control unit 17 recognizes the presence / absence of a channel designated for viewing according to the presence / absence of an input operation from the user, and advances the processing to step S15.

  In step S15, the control unit 17 determines whether or not the tuner function in the TV control unit 12 of the terminal itself is activated (= whether or not the tuner function is valid), and if the tuner function is valid. The process proceeds to step S16, and if the tuner function is not provided or the tuner function is invalid, the process proceeds to step S18.

  In step S <b> 16, the control unit 17 determines whether or not to execute the “shared reception function” described with reference to FIGS. 13 and 14. If the “shared reception function” is to be executed, the process proceeds to step S26. If the “shared reception function” is not to be executed, the process proceeds to step S17.

  In step S17, the tuner function of the own terminal is valid, and since the “shared reception function” is not executed, the control unit 17 performs recording according to the “tuning determination routine” described with reference to the flowchart of FIG. Alternatively, the TV control unit 12 is subjected to channel selection control so as to select a channel to be viewed, and the process proceeds to step S18.

  On the other hand, when the process is advanced to step S26 when the “shared reception function” is executed, the control unit 17 is close to another mobile phone as described with reference to FIGS. By performing distance wireless communication, each segment to be received is determined, and stream data of this segment is short-range wirelessly communicated with each other. Thereby, in each mobile phone, viewing of the television broadcast by the “shared reception function” is started.

  Next, when channel selection control of the TV control unit 12 is performed according to the “tuning determination routine”, the control unit 17 transmits the stream data of the selected channel, and is transmitted from another mobile phone. The short-range wireless communication unit 14 is controlled to receive stream data, and the process proceeds to step S19.

  In step S19, the control unit 17 determines the presence / absence of a channel designated for recording by the user based on the recognition result in step S13. If there is a channel designated for recording, the process proceeds to step S20. If there is no channel designated for recording, the process proceeds to step S21.

  In step S20, since there is a channel designated for recording, the control unit 17 controls recording of the stream data of the channel designated for recording selected by the tuner function of the own terminal in the large capacity memory 15. Then, the process proceeds to step S21.

  Next, in step S21, the control unit 17 determines whether or not the execution of the “multi-program display function” described with reference to FIGS. 7 and 8 is designated by the user, and executes the multi-program display function. Is designated by the user, the process proceeds to step S27. If execution of the multi-program display function is not designated by the user, the process proceeds to step S22.

  In step S27, since the execution of the multi-program display function is designated by the user, as described with reference to FIG. 7 and FIG. Stream data of other channels transmitted from the mobile phone by short-distance wireless transmission are controlled to be displayed in the divided areas of the display unit 5 respectively. Thereby, even when only one tuner function is provided, moving image data of a plurality of channels can be displayed on one display screen.

  Next, in step S22, the control unit 17 determines whether or not the execution of the “high-speed program switching function” described with reference to FIGS. 9 and 10 is specified by the user, and executes the high-speed program switching function. Is designated by the user, the process proceeds to step S24. If execution of the high-speed program switching function is not designated by the user, the process proceeds to step S25.

  In step S24, since the execution of the high-speed program switching function is designated by the user, as described with reference to FIGS. 9 and 10, the control unit 17 displays the stream data of the channel being viewed on the display unit 5 and While controlling the output via the speaker unit 3, the stream data of other channels is controlled to be stored in the large capacity memory 15, and the process proceeds to step S25. As a result, when channel switching is designated by the user, stream data of other channels recorded in the large-capacity memory 15 can be immediately read out and output via the display unit 5 and the speaker unit 3.

Next, in step S25, the control unit 17 monitors the operation state of the operation unit 6 to determine whether or not the television broadcast viewing end operation has been performed by the user, and while the viewing end operation is not detected. Then, the process is returned to step S11, the processes in steps S11 to S25 are repeatedly executed, and the process shown in the flowchart of FIG. 15 is terminated at the timing when the viewing end operation is detected.

[Effect of the embodiment]
As is clear from the above description, the mobile phone according to the present embodiment uses the “background recording function” to record the channel selected by the own terminal even though it has only one tuner function. It is possible to view a television broadcast of another channel transmitted from another mobile phone by distance wireless communication.

  In addition, by using the “multi-program display function”, a plurality of mobile phones can select different channels, and the stream data of each channel can be communicated with each other via short-range wireless communication, so that one display screen can be displayed in multiple display areas. The television broadcast of each channel can be displayed on each divided screen. For this reason, television broadcasts of a plurality of channels can be displayed as a list, and the user can easily select a desired channel.

  In addition, the “high-speed program switching function” allows a user to view a television broadcast of a desired channel and capture stream data of a channel other than the currently viewed channel from another mobile phone via the short-range wireless communication unit 14. When the user performs a channel switching operation, the decoded stream data of the other channels recorded in the large-capacity memory 15 is immediately recorded. And can be displayed on the display unit 5 or the like. For this reason, it is possible to perform channel switching at high speed while omitting the time required for channel selection of other channels and decoding processing of stream data of other channels.

  In addition, by using the “tunerless function” to capture stream data of a channel selected by another mobile phone via the short-range wireless communication unit 14, a mobile phone that does not have a tuner function can also be used as desired. The television broadcast of the channel can be viewed.

In addition, when a television broadcast of one channel is formed by stream data of a plurality of segments, the “sharing reception function” receives the stream data of each segment by sharing with other mobile phones. By receiving the stream data of the segments with each mobile phone via the short-range wireless communication unit 14, it is possible to view a television broadcast formed by the stream data of a plurality of segments.
