  The memory 33 stores the second program guide data included in the data decoded by the demodulator 32. The second program guide data stored in the memory 33 is SI data for all broadcast channels that can be received by the one-segment tuner 31. Specifically, on the display 34, based on the second program guide data stored in the memory 33, the EPG screen, the TV program with the program name in the EPG screen, and further displayed on the display 24 of the TV 2 are displayed. A TV EPG screen having the same content as the EPG screen based on the first program guide data is displayed. The operation unit 37 includes an EPG display button 37 a for displaying an EPG screen based on the second program guide data on the display 34, and a TV EPG display button 37 b for displaying the TV EPG screen on the display 34. A selection key 37c for performing various selection operations is provided.

  The CPU 39 has a function of creating an EPG screen based on the second program guide data and displaying it on the display 34 when the EPG display button 37a of the operation unit 37 is pressed by the user. When the TV EPG display button 37b of the operation unit 37 is pressed by the user, the CPU 39 transmits / receives a program guide data request command for requesting the first program guide data stored in the memory 23 to the television 2. 38. In addition, the CPU 39 creates a television EPG screen based on the first program guide data transmitted from the television 2 and displays it on the display 34. When creating the EPG screen for television, the display format used for the EPG screen based on the second program guide data is referred to. Further, when the user selects a predetermined program name from the television EPG screen displayed on the display 34 by using the selection key 37c, the CPU 39 displays a television program with the selected program name on the television 2. A television program display command for instructing to be displayed on the screen 24 is transmitted from the transmission / reception unit 38.

  Next, in the present system 1, an operation of displaying a television EPG screen on the display 34 of the mobile phone 3 and displaying a predetermined television program on the display 24 of the television 2 using the television EPG screen will be described. FIG. 3 shows the procedure of the above operation in time series. When the TV EPG display button 37b of the operation unit 37 is pressed by the user (S101), the CPU 39 of the mobile phone 3 requests the TV 2 to request the first program guide data stored in the memory 23. A table data request command is transmitted from the transmission / reception unit 38 (S102). When the transmission / reception unit 27 of the television 2 receives the program guide data request command from the mobile phone 3 (S103), the CPU 28 of the television 2 sends the first program guide data stored in the memory 23 from the transmission / reception unit 27 to the mobile phone 3. Transmit (S104). When the transmitting / receiving unit 38 of the mobile phone 3 receives the first program guide data from the television 2 (S105), the CPU 39 of the mobile phone 3 creates a television EPG screen based on the received first program guide data. Is displayed on the display 34 (S106).

  When the TV EPG screen is displayed on the display 34, the user selects a predetermined program name from the TV EPG screen using the selection key 37c of the operation unit 37 (S107). Transmits a television program display command for instructing the television 2 to display the television program having the selected program name on the display 24 from the transmission / reception unit 38 (S108). At this time, the user can select a plurality of predetermined program names, and the television program display command is transmitted each time the user selects a program name. This television program display command includes information such as the broadcast start time, broadcast end time, and broadcast channel of the television program. When the transmission / reception unit 27 of the television 2 receives a television program display command from the mobile phone 3 (S109), the CPU 28 of the television 2 determines whether or not broadcasting of the television program is started based on the content of the command ( S110). When the broadcast is started (YES in S111), the CPU 28 of the television 2 immediately displays the television program based on the content of the television program display command on the display 24 (S112). On the other hand, if the broadcast has not been started (NO in S111), the CPU 28 of the television 2 makes a viewing reservation for the television program based on the content of the television program display command (S113).

  As described above, according to the television system 1 according to this embodiment, when the television EPG display button 37b of the operation unit 37 is pressed by the user, the television content having the same content as the EPG screen displayed on the display 24 of the television 2 is displayed. Since the EPG screen is displayed on the display 34 of the mobile phone 3, the convenience of the EPG function of the television 2 is improved. At this time, the user cannot obtain the TV program information from the EPG screen based on the second program guide data, specifically, the TV program information of the channel that cannot be received by the one-segment tuner 31 or the future TV. Program information and the like can be acquired from the mobile phone 3. When a predetermined program name is selected by the user from the TV EPG screen displayed on the display 34 of the mobile phone 3, the TV program having the selected program name is displayed on the display 24 of the TV 2. A TV program display instruction to instruct is transmitted. Thereby, since the user can view a desired television program on the display 24 of the television 2, the convenience of the EPG function of the television 2 is further improved.

  In addition, this invention is not restricted to the structure of the said embodiment, A various deformation | transformation is possible in the range which does not change the meaning of invention. For example, in the above-described embodiment, the mobile phone 3 is illustrated as a mobile terminal that can communicate with the television 2, but the present invention is not limited to this, and the terminal may be a portable game machine with a built-in one-segment tuner 31. Further, the TV 2 may be provided with a recorder function so that when the TV program with the program name based on the content of the TV program display command is not started, the TV program is recorded. .
