  Next, normal reservation recording / playback processing and latest program recording / playback processing by the digital television receiver 11 will be described.

  First, an example of normal reserved recording / playback processing will be described. The user instructs display of an electronic program guide (EPG) via the remote controller 17 (program guide key 17h). In response to this instruction, the control module 65 controls the display of the electronic program guide. That is, the signal processing module 51 outputs the electronic program guide included in the broadcast signal, and thereby the electronic program guide is displayed on the video display 14. Further, the user selects a program to be recorded from the electronic program guide via the remote controller 17 (direction key 17i, determination key 17g), and instructs the recording reservation of the selected program (ordinary recording reservation instruction). . The non-volatile memory 68 of the control module 65 registers recording reservation information for the selected program (regular recording recording registration). By repeating selection of a program to be recorded and designation of recording reservation for the selected program, recording reservation information for a plurality of programs can be registered.

  The control module 65 controls the recording of the plurality of programs based on the recording reservation information of the plurality of registered programs. That is, the control module 65 instructs the selection of the broadcast channel of the scheduled recording program when the scheduled recording time included in the scheduled recording information is reached (or when a predetermined time before the broadcast time is reached). In response to this instruction, the tuner 49, 54, or 52 selects the broadcast channel of the scheduled recording program. As a result, the signal of the broadcast channel of the scheduled recording program is input to the signal processing module 51. Further, the control module 65 inputs the broadcast channel signal of the scheduled recording program input to the signal processing module 51 to the HDD 78. The HDD 78 records the broadcast channel signal of the input scheduled recording program. By repeating the selection of the broadcast channel of the scheduled recording program and the recording of the broadcast channel signal of the scheduled recording program, all the scheduled recording programs included in the scheduled recording information can be recorded. In addition, the control module 65 generates a recording list corresponding to the recording of the recording reservation program described above, and the HDD 78 records the recording list.

  When the user instructs the recording list display via the remote controller 17, the control module 65 controls the recording list display. That is, the control module 61 receives the recording list from the HDD 78 and supplies the recording list to the OSD signal generation module 61. The OSD signal generation module 61 generates an OSD signal based on the recording list and supplies the OSD signal to the graphic processing module 58. The graphic processing module 58 superimposes and outputs the OSD signal on the video signal supplied from the signal processing module 51. Alternatively, the graphic processing module 58 switches the video signal supplied from the signal processing module 51 to the OSD signal and outputs it. As a result, the video display 14 displays a recording list based on the OSD signal.

  The control module 65 manages the recording state and viewing history of each recorded program, and controls the display of the recording state and viewing history on the recording list. For example, the control module 65 records the recording state information including the recording information in association with the recording data of the program A corresponding to the recording of the program A, and records the recording state information corresponding to the completion of the recording of the program A. The recording in-progress information included in is updated to the recording completion information. Further, the control module 65 records the reproduction history information including unreproduced information in association with the recording data of the program A corresponding to the recording of the program A, and reproduces the program A being recorded or the recorded program A. In response to this, the unreproduced information included in the reproduction history information is updated to the reproduced information. As a result, on-recording information is displayed on the recording list corresponding to the title of program A being recorded. Further, unreproduced information is displayed on the recording list corresponding to the title of the unreproduced program A. Further, reproduced information is displayed on the recording list corresponding to the title of the reproduced program A.

  When the user selects a recording title in the recording list via the remote controller 17 (direction key 17i, determination key 17g), the control module 65 controls the reproduction of the selected recording title. That is, the control module 65 receives the audio data and video data of the selected recording title from the HDD 78 and supplies them to the signal processing module 51. The signal processing module 51 supplies the audio data of the selected recording title to the audio processing module 59, and supplies the video data of the selected recording title to the graphic processing module 58. As a result, the selected recorded title is reproduced.

  Next, an example of the latest program recording / playback process (always news) will be described. The user instructs display of an electronic program guide (EPG) via the remote controller 17 (program guide key 17h). In response to this instruction, the control module 65 controls the display of the electronic program guide. In other words, the signal processing module 51 outputs the electronic program guide included in the terrestrial digital television broadcast signal, whereby the electronic program guide is displayed on the video display 14. Furthermore, the user selects a program to be recorded from the electronic program guide via the remote controller 17 (direction key 17i, determination key 17g), and instructs grouping of recording reservations of the selected program (at any time, news recording). Reservation instructions).

  Here, the recording reservation grouping will be described with a specific example. For example, the user selects a news program A to be recorded from the electronic program guide, reserves daily recording of the selected news program A or recording from Monday to Friday, and instructs grouping. Thereby, the daily recording of the selected news program A or the recording from Monday to Friday is registered in one group. Thereby, the recording / playback processing of the news program A registered as a group is distinguished from the normal reserved recording / playback processing.

  Alternatively, the user selects news program A, news program B, and news program C to be recorded from the electronic program guide, reserves recording of the selected news programs A, B, and C, and instructs grouping. Thereby, the recordings of the selected news programs A, B, and C are registered in one group. Thereby, the recording / playback processing of the news programs A, B, and C registered as a group is distinguished from the normal reserved recording / playback processing.

  Alternatively, the user selects a news program A to be recorded from the electronic program guide, reserves daily recording of the selected news program A or recording from Monday to Friday, and instructs grouping. Thereby, the daily recording of the selected news program A or the recording from Monday to Friday is registered in one group. Further, the user selects news program B and news program C to be recorded from the electronic program guide, reserves recording of the selected news programs B and C, and instructs grouping. Thereby, the daily recording of the selected news program A or the recording of Monday to Friday and the recording of the selected news programs B and C are registered in one group. Thereby, the recording / playback processing of the news programs A, B, and C registered as a group is distinguished from the normal reserved recording / playback processing.

  Corresponding to the above selection operation and grouping instruction operation by the user, the non-volatile memory 68 of the control module 65 groups and registers the recording reservation information of the selected program (registration of news recording reservation at any time). By repeating the selection of the program to be recorded and the designation of the recording reservation grouping of the selected program, the recording reservation information of the programs can be grouped and registered. That is, it is possible to distinguish the recording / playback processing of a group-registered program from normal reserved recording / playback processing.

  The control module 65 controls the recording of the program based on the grouped recording reservation information. That is, the control module 65 instructs the selection of the broadcast channel of the scheduled recording program when the scheduled recording time included in the scheduled recording information is reached (or when a predetermined time before the broadcast time is reached). In response to this instruction, the tuner 49, 54, or 52 selects the broadcast channel of the scheduled recording program. As a result, the signal of the broadcast channel of the scheduled recording program is input to the signal processing module 51. Further, the control module 65 inputs the broadcast channel signal of the scheduled recording program input to the signal processing module 51 to the HDD 78. The HDD 78 records the broadcast channel signal of the input scheduled recording program.

  At this time, the control module 65 leaves only the latest recorded program among the recorded programs recorded based on the recording reservation information of the grouped programs, and deletes recorded programs other than the latest recorded program. As a result, the recorded program recorded based on the recording reservation information of the grouped programs is always only the latest recorded program. Therefore, the recording list of the recorded programs recorded based on the recording reservation information of the grouped programs may not be displayed. Note that a recorded program other than the latest recorded program may be left without being deleted, and a recording list of the recorded programs may be displayed. As a result, by selecting a recorded program other than the latest one that was missed from the recording list of the recorded program, it is possible to view the recorded program other than the latest one that was missed.

  When the user instructs playback (special playback) via the remote controller 17 (special playback key 17q), the control module 65 controls playback of the latest recorded program that remains. That is, the control module 65 receives the remaining audio data and video data of the latest recorded program from the HDD 78 and supplies them to the signal processing module 51. The signal processing module 51 supplies the audio data of the latest recorded program remaining to the audio processing module 59 and supplies the video data of the latest recorded program remaining to the graphic processing module 58. As a result, the latest recorded program remaining is reproduced.

  According to the normal reservation recording / playback processing described above, a plurality of various programs such as movies, dramas, and sports can be recorded, and a favorite program can be selected from a plurality of recorded programs (in a recording list). You can select and play. That is, a favorite program can be selected and reproduced from a program recorded today, a program recorded yesterday, and a program recorded one week ago.

  On the other hand, the latest program recording / playback process is suitable for recording a program in which the latest information such as news and weather forecast is regarded as important. Therefore, in the latest program recording / playback process, only the latest program is left and programs other than the latest program are deleted. Therefore, the recording list display can be omitted, and the latest program can be reproduced in response to the special reproduction instruction.

  Note that the digital television receiver 11 can perform both the normal reserved recording / playback processing and the latest program recording / playback processing separately. In other words, normal scheduled recording / playback processing is suitable for processing programs that are worth watching even after a considerable amount of time has elapsed after recording, and the latest program recording / playback processing is processing for programs that emphasize newness. Suitable for

  Further, when the recording time of the normal reserved recording / playback process and the recording time of the latest program recording / playback process overlap, for example, the recording of the normal reserved recording / playback process is given priority.

  Next, with reference to FIG. 4, the guidance display of the recording state and the reproduction history in the latest program recording / reproducing process will be described. As described above, the recording list display can be omitted in the latest program recording / playback processing. For this reason, it may not be possible to check the recording status (recording / recording complete) and playback history (unplayed / played) of the program to be played back using the recording list.

  Therefore, in the latest program recording / reproducing process, the recording state is displayed before reproduction or the reproduction history is displayed. Therefore, in the latest program recording / playback process, the recording state, playback history, and recording information (recording date information, etc.) are acquired and stored (step S41).

  For example, the control module 65 records the recording state information including the recording information in association with the video signal and the audio signal of the program A in response to the recording of the program A, and responds to the completion of the recording of the program A. The recording in-progress information included in the recording status information is updated to the recording completion information. The control module 65 records the reproduction history information including unreproduced information in association with the video signal and audio signal of the program A corresponding to the recording of the program A, and the program A being recorded or the recorded program is recorded. Corresponding to the reproduction of A, the unreproduced information included in the reproduction history information is updated to the reproduced information.

  In addition, the control module 65 generates recording information based on the program information included in the broadcast signal of the program A, and records the recording information together with the video signal and the audio signal of the program A. For example, the recording information includes a channel number, a title, and broadcast date / time information (recording date / time information). Note that the recording date / time information may be generated from current time information held by the digital television receiver 11.

  When the user instructs the latest recorded program playback via the remote controller 17 (special playback key 17q), the control module 65 determines that the recording status information of the latest recorded program (for example, program A) includes information being recorded. In addition, the in-recording information is supplied to the OSD signal generation module 61, and the recording date and time information included in the recording information of the latest recorded program (for example, program A) is also supplied to the OSD signal generation module 61. The OSD signal generation module 61 generates an OSD signal based on the recording information and the recording date / time information, and supplies the OSD signal to the graphic processing module 58. The graphic processing module 58 superimposes and outputs the OSD signal on the video signal supplied from the signal processing module 51. As a result, as shown in FIG. 5, the video display device 14 displays the recording information and the recording date / time information (step S42).

  Alternatively, if the recording state information of the latest recorded program (for example, program A) includes recording completion information and the reproduction history information includes unreproduced information, the control module 65 sends the unreproduced information to the OSD signal generation module 61. The recording date and time information included in the recording information of the latest recorded program (for example, program A) is also supplied to the OSD signal generation module 61. The OSD signal generation module 61 generates an OSD signal based on the unplayed information and the recording date / time information, and supplies the OSD signal to the graphic processing module 58. The graphic processing module 58 superimposes and outputs the OSD signal on the video signal supplied from the signal processing module 51. Thereby, as shown in FIG. 6, unreproduced information (for example, “new”) and recording date and time information are displayed on the video display 14 (step S42).

  Alternatively, when the recording status information of the latest recorded program (for example, program A) includes recording completion information and the reproduction history information includes reproduced information, the control module 65 determines the latest recorded program (for example, program A). The recording date / time information included in the recording information is supplied to the OSD signal generation module 61. The OSD signal generation module 61 generates an OSD signal based on the recording date and time information, and supplies the OSD signal to the graphic processing module 58. The graphic processing module 58 superimposes and outputs the OSD signal on the video signal supplied from the signal processing module 51. Thereby, as shown in FIG. 7, only the recording date and time information is displayed on the video display 14 (step S42).

  Alternatively, the control module 65 sends the reproduced information to the OSD signal generation module 61 when the recording state information of the latest recorded program (for example, program A) includes recording completion information and the reproduction history information includes reproduced information. The recording date and time information included in the recording information of the latest recorded program (for example, program A) is also supplied to the OSD signal generation module 61. The OSD signal generation module 61 generates an OSD signal based on the reproduced information and the recording date / time information, and supplies the OSD signal to the graphic processing module 58. The graphic processing module 58 superimposes and outputs the OSD signal on the video signal supplied from the signal processing module 51. Thereby, as shown in FIG. 8, the reproduced information (for example, “viewed”) and the recording date / time information are displayed on the video display 14 (step S42). Note that the control module 65 can display the reproduction date and time as shown in FIG. 8 by managing the reproduction date and time information.

  Thereafter, the control module 65 supplies the recorded data of the latest recorded program (for example, program A) to the signal processing module 51. The signal processing module 51 supplies audio data of the latest recorded program to the audio processing module 59 and supplies video data of the latest recorded program to the graphic processing module 58. Thereby, the latest recorded program is reproduced (step S43).

  As described above, after the recording state or the reproduction history is reproduced, the latest recorded program (main part) is reproduced. As a result, the user knows whether the latest recorded program to be played back is a recorded program, an unplayed program, a played program, and when it has been played, when it was played. be able to.

  In addition to the recording date and time described above, the channel number of the recorded program and the title of the recorded program may be displayed. Thereby, various information regarding the program can be known before reproduction.

  When the recorded information is played back (displayed), the main part of the recorded program is played back, and when playback of the main part is paused or stopped and then restarted, the recorded information is played back again (displayed) and then the main part is played back. Resume playback of. This makes it possible to distinguish between playback of a recorded program and playback of a program broadcast in real time even when time has elapsed since playback of the main story was paused or stopped.

  The module described above may be realized by hardware, or may be realized by software using a CPU or the like.

  Note that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention in the implementation stage.
