  Next, processing when the back program guide of the program information display device 1 is displayed will be described with reference to the flowchart shown in FIG.

  Here, it is assumed that program information for all channels of BS digital broadcasting and program information for all channels of CS digital broadcasting are stored in advance in the program information storage unit 5. In addition, channel scan of terrestrial digital broadcasting is performed in advance, and program information acquisition unit 9 acquires program information for all channels of terrestrial digital broadcasting in the viewing area, and is stored in program information storage unit 5 And

  First, in step 1 (hereinafter referred to as S1), a broadcast program is displayed on the display panel 7. Here, it is assumed that a broadcast program of BS digital broadcasting is displayed.

  In S2, the input receiving unit 13 determines whether or not there is a key input. If it is determined that there is a key input (input reception unit 13 receives a key input) (YES in S2), the process proceeds to S3. When it is determined that there is no key input (the input receiving unit 13 has not received a key input) (NO in S2), S2 is repeated. In other words, the display of the BS broadcast program is continued until a key is input.

  In S <b> 3, the input receiving unit 13 determines whether or not the key input is an input from the back program button 20. If the input is from the back program button 20 (YES in S3), the process proceeds to S6. If the input is not from the back program button 20 (NO in S3), the process proceeds to S4.

  In S <b> 4, the input receiving unit 13 determines whether or not the key input is an input from the network button 21. If the input is from network button 21 (YES in S4), the process proceeds to S7. If the input is not from the network button 21 (NO in S4), the process proceeds to S5. Here, it is assumed that the CS digital broadcast button 24 is selected and pressed as the network button 21.

  In S <b> 5, the input receiving unit 13 determines whether the key input is an input from the determination button 25. If the input is from enter button 25 (YES in S5), the process proceeds to S8. If the input is not from the determination button 25 (NO in S5), the process proceeds to S14.

  In S6, it is determined whether or not the back program guide is being displayed. If the back program guide is being displayed (YES in S6), the process proceeds to S9. If the back program guide is not being displayed, the process proceeds to S10.

  In S7, it is determined whether the back program guide is being displayed. If the back program guide is not being displayed, the process proceeds to S11. If the back program guide is being displayed (YES in S7), the process proceeds to S12.

  In S8, it is determined whether the back program guide is being displayed. If the back program guide is being displayed (YES in S8), the process proceeds to S13. If the back program guide is not being displayed, the process proceeds to S14.

  In S9, the display control unit 12 does not display the displayed back program guide. That is, the display of the back program guide is cleared.

  In S10, the viewable program data creation unit 10 reads out the program information of the BS digital broadcast from the program information storage unit 5 and creates back program table data. Then, the display control unit 12 superimposes and displays the back program table of the BS digital broadcast created by the viewable program data creation unit 10 on the broadcast program of the BS broadcast.

  In S11, since the CS digital broadcast button 24 is selected in S4, the digital demodulation unit 2 acquires data in synchronization with the CS digital broadcast broadcast program, and the display control unit 12 displays the CS digital broadcast broadcast program. To do.

  In S12, since the CS digital broadcast button 24 is selected in S4, the viewable program data creation unit 10 reads out the program information of the CS digital broadcast from the program information storage unit 5 and creates back program table data. Then, the display control unit 12 superimposes and displays the CS broadcast back program table created by the viewable program data creation unit 10 on the BS broadcast program. At this time, for example, the display panel 7 is configured as shown in FIG. 4, and the CS digital broadcast back program guide is displayed while the BS broadcast program is displayed.

  In S13, since any channel in the reverse program table is selected and accepted by pressing the decision button 25 in S5, the digital demodulator 2 tunes to the selected channel and broadcast signal is received. Receive. At this time, program information is acquired by the program information acquisition unit 9 and stored in the program information storage unit 5.

  In S14, other processes corresponding to the key input in S2 are performed.

  As described above, for example, by the key input using the remote controller 8, the program information display device 1 can superimpose and display the back program table of the CS digital broadcast while the broadcast program of the BS digital broadcast is displayed.

  A conventional program information display device must perform an operation for switching tuner input when displaying a program guide of another network while displaying a back program guide of a network including a currently viewed broadcast program. . Due to this operation, the broadcast program currently being viewed has disappeared in the conventional program information display device.

  In contrast to such a conventional program information display device, when the program information display device 1 displays the back program table of the CS digital broadcast while displaying the BS digital broadcast broadcast program, the program stored in the storage unit is displayed. The data of the back program guide of CS digital broadcasting created based on the information is created. Therefore, it is not necessary to perform an operation for tuning to a specific channel of CS digital broadcasting and acquiring data. That is, there is no need to perform a tuner input switching operation. Then, the back program table of the CS digital broadcast is superimposed and displayed while the BS digital broadcast broadcast program is displayed. Further, when a BS digital broadcast broadcast program is being displayed, the back program table of the digital terrestrial broadcast created based on the program information stored in the storage unit can be superimposed and displayed. Of course, the reverse program table of CS digital broadcast or the reverse program table of BS digital broadcast can be superimposed and displayed on the broadcast program of terrestrial digital broadcast. Also, a BS digital broadcast back program guide or a terrestrial digital broadcast back program guide can be superimposed on the CS digital broadcast program.

  Therefore, the program information display device 1 can superimpose and display the back program table of another broadcast network without erasing the display of the broadcast program of the currently viewed broadcast network. Since the broadcast program of the currently viewed broadcast network does not disappear, the user can watch the broadcast program of the currently viewed broadcast network and the broadcast network including the currently viewed broadcast program. Can check the back program guide of the broadcasting network with different operation rules. Therefore, the user can check all viewable program data while viewing the currently viewed broadcast program.

  Further, as described above, the program information display device 1 can switch the BS digital broadcast back program guide and the CS digital broadcast back program guide to be superimposed and displayed on the BS digital broadcast broadcast program. Of course, the BS digital broadcast back program guide and the terrestrial digital broadcast back program guide can be switched and superimposed on the BS digital broadcast program. In addition, a CS digital broadcast back program guide and a terrestrial digital broadcast back program guide can be switched and superimposed on a BS digital broadcast program. Similarly, the display of the back program table can be switched and displayed in a superimposed manner while displaying a digital terrestrial broadcast program or a CS digital broadcast program. The user can switch the superimposed display of the back program guide with the network button 21. At this time, the program information display device 1 switches and displays only the back program table without switching the broadcast program to another broadcast network. Therefore, the user can switch only viewable data to another network when viewingable program data is superimposed on the broadcast program. Therefore, the back program guide can be confirmed comfortably.

  In the program information display device 1, optimization regarding display, such as review of the font size of the back program guide and simplification of expression, may be achieved. As a result, it is possible to provide the same listability as before even in a smaller display area. In this way, by maintaining the information listing while reducing the back program display area, program information can be presented without disturbing the currently viewed program image. Conventionally, large fonts were used due to limitations of display processing chips. As a result, the station name cannot be displayed due to the limitation of the number of display characters, the number of display characters of the program title is small, the button function description column at the bottom of the screen called guidance is displayed over the entire width of the screen, etc. there were. However, it is possible to use finer fonts by improving the capability of the display processing chip, and as a result, the above-mentioned problems of the prior art can be solved. Further, a display method that gives priority to user viewing may be used, such as increasing the number of broadcast stations that can be listed while reducing the display area of the back screen table on which the screen is superimposed. Note that the optimum viewing distance for high-definition broadcasting is said to be about three times the screen height, and it is preferable to adjust the font size so that it can be recognized sufficiently from that distance.

  Each block of the program information display device 1 may be configured by hardware logic, or may be realized by software using a CPU as follows.

  That is, the program information display device 1 includes a CPU (central processing unit) that executes instructions of a control program that realizes each function, a ROM (read only memory) that stores the program, and a RAM (random access memory) that expands the program. ), And a storage device (recording medium, not shown) such as a memory for storing the program and various data.
