Abstract

PURPOSE:To simply retrieve an arbitrary program and to reproduce it by providing an external memory capable of recording the contents of the broadcasting of a specific channel received by a television receiver for a prescribed time, adding an index to the contents of the broadcasting and updating and recording them by said external memory. CONSTITUTION:The channel of the television receiver 1 is fixed to one specific channel and the external memory 3 is set to a recording mode, and then, the data of the picture and the sound of the broadcasting of said channel is recorded on the external memory 3 together with a data and time inputted from a clock 4. In case of reproducing, after the external memory 3 is set to a reading mode, for instance, the television program column of or the like such as a newspaper is viewed to input the data of the data and the time (data at the time of starting the program) when a desired program is broadcasted from a date and time setting part 5, and then the data of said date and time is transferred to the external memory 3 as a retrieving code to start the reading of a succeeding part from the part corresponding to said data. Thereby, a reproduction is carried out in the television receiver 1 based thereon.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device that can arbitrarily reproduce the contents of a television broadcast after the broadcast ends.

[Conventional technology]

VTR is a device that can record the contents of television broadcast programs.
(video tape recorder), which can be played back at any time and is extremely convenient.

[Problem to be solved by the invention]

However, these VTRs only record the contents of broadcasts, and therefore, if a plurality of program contents are recorded, it often takes time to search for a desired program when playing back later.

SUMMARY OF THE INVENTION An object of the present invention is to provide a television broadcast recording device that greatly simplifies program searches.

[Means to solve the problem]

To this end, the present invention comprises a television receiver and an external memory capable of recording broadcast content of a specific channel received by the television receiver for a predetermined period of time, and updates the broadcast content by adding an index to the external memory. I made it record.

〔Example〕

Examples of the present invention will be described below. FIG. 1 is a block diagram of one embodiment. Reference numeral 1 denotes a television receiver, which has a function of reproducing the contents of television broadcast programs taken in from an antenna 2.

Reference numeral 3 denotes an external memory that can be erased and re-recorded and endlessly recorded. A VTR is used as this external memory.

Perpendicular magnetization VTR1, rewritable optical disks, and others can be used. Reference numeral 4 denotes a clock, which is used to add date and time data to the recorded image data in the external memory 3. 5 is a date/time setting section, which functions as a search section.

Now, in this embodiment, the channel of the television receiver 1 is fixed to one specific channel, and the external memory 3
If you set it to recording mode, the image and audio data of the broadcast of that channel will be stored in the external memory 3 on the clock 4.
It is then recorded along with date and time data manually generated.

When the external memory 3 has been recorded to its full capacity, new recording is performed while erasing the previously recorded contents from the first recording area. This allows endless recording. Therefore, for example, if the capacity of the external memory 3 is set to one week's worth, the latest one will always be stored in the external memory 3.
This means that the contents of a week's worth of television programs are recorded.

To playback, after setting the external memory 3 to read mode, look at the TV program section of a newspaper, etc., and set the date and time when the desired program was broadcast from the date/time setting section 5.
When you enter time data (data at the time the program starts),
The date/time data becomes a search code and is transferred to the external memory 3, and reading of the subsequent parts starts from the part corresponding to the data. Therefore, reproduction is performed on the television receiver 1 based on this.

FIG. 2 is a diagram showing the pattern of this reproduction. For example, time T
When the data for a is entered manually from the date/time setting section 5, playback starts from the beginning of program a, when the data for time Tb is entered in the same way, playback starts from the beginning of the program, and the data for time Tc is entered in the same way. When input, playback starts from the beginning of program C.

Note that in the above, since the date/time data does not need to be reproduced, the data is appropriately removed by a processing circuit before being reproduced.

In addition, although the date/time data is used as an index for program search in the above example, if the title of the program is sent as data from the broadcasting station, record that title as an index and use it during playback. You can search for the title and play the desired program.

In this case, it is possible to intensively reproduce only the title and search using a menu without looking at the program section of the newspaper.

Figure 3 is an explanatory diagram of this example, and in the first menu "
By keying in ``8#'', the menu changes to the ``Music'' menu. Then, if you key in the chord of the desired singer, for example "*5#", r Mills.
Brothers' program (30 minutes) will be played.

Although the above explanation deals with only one channel, the TV receiver is equipped with multiple tuners and signal processing units so that it can receive multiple channels simultaneously, and the external memory also stores multiple channels. If the capacity is set to the maximum possible, post-mortem examination and playback of multiple channels will be possible.

[Effects of the Invention] As described above, according to the present invention, an arbitrary program can be easily searched and reproduced from the contents of a plurality of programs broadcast over a relatively long period of time.
