Abstract

PURPOSE:To facilitate the retrieving program by recording the date of picture recording into a video tape and displaying it to a reproducing picture. CONSTITUTION:A picture recording date data processing part 12 sends the picture recording date data into a cassette video tape recorder main body 11 through a picture recording date data writing part 13 and writes the picture recording date data into the tape. The processing part 12 reads the picture recording date data through a picture recording date data reading part 14 and displays them in a displaying part 15 such as a TV.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a video tape recorder for recording television programs and the like.

[Conventional technology]

Video tape recorders have become rapidly popular, and many households now record television programs. Additionally, many video tape recorders have a mode that allows long-term recording. Therefore, by using relatively long video tapes, series, programs, etc. can be recorded continuously.

[Problem to be solved by the invention]

However, when several programs are recorded on one videotape, it becomes unclear which part of the tape contains what kind of program.

For example, if you are trying to find a program that was recorded on a certain day, you can load the videotape into a videotape recorder, set it to fast-forward mode or rewind mode, and then play a predetermined amount of tape. It was necessary to run the machine, play it in playback mode, and repeat the same operation until the desired program appeared. In this case, for example, if the same drama series is recorded continuously on videotape, the characters appearing on each broadcast date are often the same, and even if the videotape is played for a short time, parts of the tape will be In many cases, it was not possible to determine whether the recorded portion corresponded to the desired broadcast date. That is, there is a problem in that finding a desired program requires a considerable amount of time and patient search work.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a video system that allows users to search for a program on a desired broadcast date in a short time even when the screens on each broadcast date are similar, such as when a series of programs is recorded. Its purpose is to provide a tape recorder.

[Means to solve the problem]

In the present invention, (i) a date and time recording means for recording the recording date and time on a videotape; (ii) a date and time reproduction means for reading the recording date and time from the videotape during image playback;
ii) The video tape recorder is provided with date and time display means for displaying the date and time reproduced by the date and time reproduction means on the screen.

That is, in the present invention, the recording date and time are recorded on the videotape, and this is displayed on the screen when the video is played back, so that it is possible to know when the video is being broadcast, and based on this, it is possible to easily search for a desired program. be able to do so.

〔Example〕

The present invention will be described in detail with reference to Examples below.

FIG. 1 shows an outline of the configuration of a video tape recorder according to an embodiment of the present invention.

This video tape recorder has a configuration in which a recording date and time data processing section 12 is added to a cassette video tape recorder main body 11. Here, the cassette video tape recorder main body 11 refers to a device part that has a function of recording images on a videotape (not shown) and a function of playing back recorded images, and is the same as a conventional conventional video tape recorder. . The cassette video tape recorder body is
It may also include a tuner function for selecting and tuning a television station.

The recording date and time data processing section 12 includes the recording date and time data writing section 1.
3, the recording date and time data is sent to the cassette video tape recorder main body 11, and the recording date and time data is written on a videotape (not shown). Further, the recording date and time data processing unit 12 reads the recording date and time data written on the videotape through the recording date and time data succession unit 14, and displays it on the screen of a television or the like connected to this video tape recorder, ie, the display unit 15. It has become.

The operation of the video tape recorder configured as above will be explained next.

(Writing date and time data) As shown in FIG. 2, the recording date and time data writing section 13 is equipped with a clock mechanism 21, and when this video tape recorder is purchased, a clock mechanism 21 for specifying the recording date and time is placed on the cassette video tape recorder body 11. The button switch 22 is used to set the current time. The current date and time data 23 outputted by the clock mechanism 21 is sent to the recording date and time data processing product 12 together with the output signal 27 of the recording date and time data writing designation switch 26 provided in the recording date and time data writing section 13.
is man-powered.

In the recording date and time data processing unit 12, when the recording date and time data writing designation switch 26 is in the on state, the recording date and time data 23
is supplied to the recording head 29 in the cassette video tape recorder main body 11, and the recording date and time data 23 is recorded in the recording state. In this way, the recording date and time are recorded on the videotape 31 in addition to recording images and audio.

(Reading date and time data) When the user of the video tape recorder presses the playback button 32 in the cassette video tape recorder main body 11, the playback head 33 reads the signal recorded on the videotape 31 and reproduces the image and audio. Also recording date and time data 2
3 is read.

Recording date and time data 23 represented by code information among these
is separated by the recording date and time data processing section 12 and supplied to the pattern generator 35 in the recording date and time data succession section 14.

The pattern generator 35 generates a dot pattern for numerically displaying the date and time indicated by the recording date and time data 23. This dot pattern data 36 is transmitted to the video signal synthesis circuit 37.
A composite video signal 38 that is combined with a video signal such as a television program is output. However, since some users of the video tape recorder do not wish to display the recording date and time data, a readout designation switch 39 is provided in the recording date and time data reading section 14, and when this switch is turned off, the recording date and time will be displayed. The displayed dot pattern data 36 is not combined with the video signal.

The composite video signal 38 is transmitted to the television display section 15 (the first
Figure). As a result, when the program is played back, the date and time of recording will be displayed at a desired position, such as a corner of the screen. In other words, the user of the video tape recorder can display the recording date and time on the display screen even when the video tape 31 is fast forwarding or rewinding, and even if it is a series program, the desired broadcast date can be used as a key. Programs can be selected quickly.

In addition, in the embodiment described above, the recording 1 data writing section 1
3 outputs a character code indicating the recording date and time and records this on the videotape 31. However, a pattern generator is provided in the recording date and time data writing unit 13 itself or in the recording date and time data processing unit, and recording The date and time may be recorded on the video tape as a video signal.

Further, in the embodiment, the recording date and time data is displayed on the television screen, but it may also be displayed on the display section of the video tape recorder main body.

〔Effect of the invention〕

According to the present invention, since the recording date and time are recorded on the videotape, it is not only possible to quickly and easily search for a program by the user's operation, but also to provide an automatic recording date and time search circuit. You can automatically search for programs. In addition, since the recorded time is displayed on the screen, the user can predict the time when the program will be finished, making it possible to more ideally manage time for viewing TV programs using a video tape recorder. Can be done.
