It shows a display example when a recording reservation of a 60-minute program called "News 11" broadcast at "24:00" is requested.

That is, at the bottom of the screen, the broadcast station name "TV1000", the program name "News 11", and the broadcast time "23: 00-24" of the program for which the user has requested recording reservations.
00 ”is displayed. In addition, at the top of the screen, a title of "favorite list" indicating that this screen is the display screen of the title list is displayed.

Further, in the center of the screen, a plurality of (four in the illustrated case) titles "news digest", which are obtained by further dividing the program "news 11",
"Community News", "Special Feature" and "Weather and Stocks"
Are displayed together with the required time. Then, the user can select and set a desired title by moving the cursor K up and down on the screen.

Here, the program "News 11" is, as shown in FIG. 4, "Opening", "Top News", "CM1", "Special Feature", "CM2", "Local News", "Weather". Forecast "," CM3 "," Other News "and" Ending "are subdivided into 10 contents, and the time stamp values indicating the start time and end time of each content specify the in-program index of the content. It has become possible to be assigned.

Then, the CPU 14 causes the "news 1
When the recording reservation of the program "1" is requested, each content constituting the program is recognized from the in-program index, and based on a preset algorithm, two contents of "top news" and "other news" are recognized. The contents are included in one title called "News Digest" and displayed as a list.

The CPU 14 includes the contents of "regional news" in the title of "community-based news", the contents of "special feature" in the title of "special feature", and the content of "weather forecast" in "weather". It is included in the title "Stocks" and displayed as a list.

In such a state, the user performs step S
16. In FIG. 16, if the title "News digest" is selected and set from the list screen shown in FIG.
In step S17, the PU 14 creates a recording time table for recording reservations of two contents of “top news” and “other news”, and the recording reservation is made here for each program “news 11” in units of contents. It is completed and is ended (step S18).

In this recording time table, the recording operation is started when the time stamp value which is the start point of "Top News" becomes "10", and the time stamp value which is the end point of "Top News" is " The recording operation is stopped when "20" is reached, the recording operation is started when the time stamp value which is the start time of "other news" is "49", and the recording operation is started when "other news" is ended. The recording / reproducing apparatus 19 is instructed to stop the recording operation when a certain time stamp value becomes "57".

FIG. 5 is a flow chart summarizing the operation in which the CPU 14 controls the recording / reproducing device 19 to the recording state and the stopped state based on the recording time table created as described above.

That is, it is started (step S19),
In step S20, when the broadcast of the recording-reserved program (“News 11” in this case) is started, the CPU 14
In step S21, it is determined based on the recording time table whether or not the recording operation start time has been reached.

When it is determined that the recording / reproducing device 19 has not arrived (NO), the CPU 14 controls the recording / reproducing device 19 in the stopped state in step S22. When it is determined that the recording operation start time has been reached (YES), the CPU 14
Controls the recording / reproducing apparatus 19 to the recording operation state in step S23.

After that, the CPU 14 executes step S24.
Then, based on the recording time table, it is determined whether or not the recording operation stop time has been reached, and if it is determined that the time has not been reached (NO), the process returns to step S21.

After step S22, or when it is determined in step S24 that the recording operation stop time has been reached (YES), the CPU 14 causes step S2.
In step 5, it is determined whether or not the content to be recorded still remains in the recording-reserved program. If it is determined that the content remains (YES), the process returns to step S21 and does not remain. When it is determined that the answer is NO (NO), the process ends (step S26).

According to the above-described embodiment, a plurality of contents constituting the program for which the recording reservation is requested are sorted by title and displayed in a list, and only the contents included in the title selected and set by the user are sequentially recorded. I have to.

That is, instead of recording in program units as in the past, it is possible to edit and record the portion of the program that the user further needs, so that the convenience for the user can be improved. .

Also, by selecting and setting a desired title from the list display screen, recording reservations for a plurality of contents included in the title are automatically made, which is also convenient for the user. Becomes

Further, a time stamp value indicating the start time, end time, etc. of each content is assigned based on the in-program index broadcast together with the program data, and the recording operation for each content is performed based on this time stamp value. Since the control is performed, it is possible to effectively use the in-program index and easily perform recording in content units.

In the above embodiment, the CPU 1
4 creates a title list based on a preset algorithm, but this title list can also be created by a broadcasting station, a broadcasting service provider or the like and provided to the user.

Also, by accumulating information such as genre statistics of programs viewed or recorded by the user and search statistics in the genre search service, the user can view or record the content that the user is likely to select. It is also possible to prompt the user to automatically create a menu for editing and recording only the content the user likes.
