  Next, a procedure for displaying an electronic program guide whose display content has been changed in the reception recording / playback apparatus according to the first embodiment will be described with reference to the flowchart shown in FIG.

  First, when an instruction to display an electronic program guide is input via the operation input unit 13, in step S110, the control unit 14 acquires time information indicating the current time from the digital broadcast wave being received. Next, in step S120, the control unit 14 controls the program information management unit 10 to acquire the electronic program guide information included in the digital broadcast wave being received.

  Next, in step S130, the control unit 14 uses the electronic program guide information, the viewing history histogram, and the preference information, and the non-viewing program frame that is assumed to have a low viewing priority among the programs scheduled to be broadcast. It is determined whether or not exists.

  As shown in FIG. 5, the preference information includes a plurality of genres and the user's preference (evaluation) for each genre. The control unit 14 generates preference information as shown in FIG. 5 according to the operation of the operation input unit 13 by the user in advance and stores it in the memory 15.

  Based on the viewing history histogram and the preference information, the control unit 14 determines the viewing priority (rank A to F) of each genre as shown in FIG. 6, and is a program frame of a genre with a low viewing priority. The non-viewing program frame is searched from the electronic program guide information. For example, in FIG. 6, a non-viewing program frame is searched from a genre of rank F (period drama, home drama, western painting, classic, western music, enka). When the non-viewing program frame exists (step S130: YES), the process proceeds to step S140. When the non-viewing program frame does not exist (step S130: NO), the normal electronic program guide is displayed and the process ends.

  In step S140, based on the recorded program list and the preference information, the control unit 14 selects a non-viewed recorded program recorded in the information recording / playback processing unit 12 in order from the genre having the highest user preference. A recorded program that is completed within the broadcast time of the viewing program frame is formulated as a playback candidate program.

  Next, in step S150, the control unit 14 causes the OSD unit 16 to generate a display screen for replacing the program content display of the non-viewing program frame in the electronic program guide with the program content display of the reproduction candidate program. Then, the electronic program guide whose display content has been changed is displayed on the video output unit 9 via the video processing unit 7.

  Through the above processing, the program content display of the non-viewing program 21 in the electronic program guide shown in FIG. 7 can be replaced with the program content display of the reproduction candidate program 22 shown in FIG.

  Next, the procedure for selecting a viewing program will be described with reference to the flowchart shown in FIG.

  In the state where the electronic program guide after the display content change as shown in FIG. 8 is displayed, in step S210, an instruction to select the program column of the reproduction candidate program 22 according to the user operation is given via the operation input unit 13. When input, in step S220, the control unit 14 causes the OSD unit 16 to generate a selection screen for displaying both the program content of the non-viewing program 21 and the program content of the reproduction candidate program 22. Then, a selection screen as shown in FIG. 10 is displayed on the video output unit 9 via the video processing unit 7. The user can select which of the non-viewing program 21 and the reproduction candidate program 22 to view on the selection screen shown in FIG.

  Next, in step S230, when the control unit 14 receives from the operation input unit 13 operation information that the user has selected either the non-viewing program 21 or the reproduction candidate program 22, the non-viewing program 21 is based on this operation information. It is determined whether or not is selected.

  When the non-viewing program 21 is selected (step S230: YES), in step S240, the control unit 14 executes a reproduction reservation for the non-viewing program 21. When the non-viewing program 21 is not selected (step S230: NO), in step S250, the control unit 14 executes a playback reservation for the playback candidate program 22.

  In step S260, the control unit 14 causes the OSD unit 16 to generate a display screen of the electronic program guide that displays the program content of the selected program among the non-viewing program 21 and the reproduction candidate program 22, and the video output unit 9 And the electronic program guide in which the reproduction reservation of the selected program is registered is stored in the memory 15. FIG. 11 shows an example of an electronic program guide when the reproduction candidate program 22 is selected and reserved for reproduction.

  As described above, according to the first embodiment, the display content of the non-viewing program 21 that is assumed to have a low viewing priority of the user in the electronic program guide is displayed based on the user's preference level among the recorded non-viewing programs. Since the program contents of the playback candidate programs 22 selected in descending order are displayed instead of being displayed, the user remains unaware of a large number of recorded programs without being aware of the presence or absence of a favorite time period. A stored program can be preferentially viewed, and viewing of an unviewed recorded program can be promoted.

  When the program column of the playback candidate program 22 is selected in the electronic program guide after the display content is changed, a selection screen displaying both the program content of the non-viewing program 21 and the program content of the playback candidate program 22 is displayed. The user can easily compare and select which of the program being broadcast and the recorded unviewed program is to be viewed.

  In the above description, the electronic program guide information is acquired from the digital broadcast radio wave. However, the method of acquiring the electronic program guide information is not limited to this, and may be acquired from the broadcast signal of the EPG dedicated channel. You may get it from the internet.

(Second Embodiment)

  Next, in step S350, the control unit 14 determines whether or not an instruction to make a playback reservation for the playback candidate program 24 according to the user operation is input from the operation input unit 13. When an instruction to make a playback reservation is input (step S350: YES), in step S360, the control unit 14 executes playback reservation for the playback candidate program 24, and then proceeds to step S370. If an instruction to make a playback reservation is not input (step S350: NO), the process proceeds to step S370.

  In step S370, the control unit 14 determines whether to select a new non-viewing program based on the operation information corresponding to the user operation. When a new non-viewing program is selected (step S370: YES), the process returns to step S320, and the subsequent processing is repeated. When a new non-viewing program is not selected (step S370: NO), in step S380, the control unit 14 displays the electronic program guide by replacing the program content display of the non-viewing program 23 with the program content display of the reproduction candidate program 24. The screen is generated in the OSD unit 16 and displayed on the video output unit 9, and the electronic program guide in which the playback reservation of the playback candidate program 24 is registered is stored in the memory 15.

  As described above, according to the second embodiment, the display candidate program 24 selected from the recorded unviewed programs is selected as the display content of the non-viewed program 23 selected as having no intention to view in the electronic program guide. Therefore, the viewing of the recorded program that has not been viewed can be promoted without hindering the viewing of the program to be viewed.
