Abstract

PURPOSE:To facilitate to retrieve a desired scene by disposing a program searching signal recording means for successively recording the program searching signal on a video tape at every fixed time in video recording. CONSTITUTION:The program searching signal is successively and automatically recorded at intervals of 30 minutes in the video recording by the program searching signal recording means 3. By operating a program searching button when the video recording is finished, the program searching signal is detected by a program searching signal detection circuit 7 at the time of fast forwarding and rewinding in the same way as the conventional video tape recorder, and the mode is changed to a reproducing mode based on the program searching signal in a mechanical control circuit 5. Thus, the rough program searching can be performed at every 30 minutes without necessitating of any operation in the video recording, and the retrieval of the desired scene can be facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a video tape recorder, and more particularly to an improvement in the cue search thereof.

<Prior Art> Conventionally, in a video tape recorder, a cue signal is automatically recorded at the start of recording, and then the cue signal is recorded by the viewer operating a button at a desired point during recording. It is equipped with a so-called VISS (Video Index Search System) function, which records the recorded cue signal and detects this recorded cue signal when fast forwarding or rewinding and shifts to playback mode. There is.

<Problems to be Solved by the Invention> However, in such conventional video tape recorders, cue signals are automatically recorded only at the start of recording. After recording a movie program or the like, if you try to watch it again from the middle of the movie, there is a problem in that it is not easy to search unless you manually record a cue signal during recording.

The present invention has been made in view of the above points, and it is an object of the present invention to enable a cue signal to be automatically recorded at a time other than the start point of recording, and to facilitate the search for a desired scene. purpose.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention includes a cueing function that detects and plays back cueing signals recorded on a videotape during recording during fast forwarding and rewinding. The video tape recorder is provided with a cue signal recording means for sequentially recording a cue signal on the videotape at regular intervals during recording.

<Operation> According to the above configuration, the recording is performed every certain period of time, for example, 30 minutes during recording.
Since cue signals are automatically and sequentially recorded every minute, it is possible to roughly cue every 30 minutes when fast forwarding or rewinding, which makes it easy to search for a desired scene.

<Examples> Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of essential parts of an embodiment of the present invention.

This video tape recorder 1, like a conventional video tape recorder, has a cue function for detecting and reproducing a cue signal recorded on the video tape 2 during recording during fast forwarding and rewinding.

Furthermore, in the video tape recorder l of this embodiment, in order to easily search for a desired scene without manually recording a cue signal during recording as in the conventional case, A cue signal recording means 3 is provided for sequentially recording cue signals on the videotape 2 at regular intervals.

This cue signal recording means 3 includes a recording time counter 4 that measures the recording time from the start of recording, and a mode signal from the output of this counter 4 and a mechanical control circuit 5. The video tape 2 includes a cue signal recording circuit 6 that sequentially records cue signals on the control track of the videotape 2 at predetermined time intervals, for example, every 30 minutes, set by a department (not shown).

The cue signal recording means 3 automatically records cue signals sequentially at 30 minute intervals during recording.

When recording is finished and the cue search button is operated, the cue signal detection circuit 7 detects the cue signal during fast forwarding and rewinding, similar to conventional video tape recorders, and the mechanical control circuit 5 detects the cue signal. Shift to playback mode based on the cue signal.

This allows you to record up to 30 seconds without having to perform any operations during recording.
It becomes possible to perform a rough cue for each minute, which makes it easy to search for a desired scene.

Incidentally, the cue signal recording means 3 automatically records a cue signal at the start of recording, similarly to conventional video tape recorders, and allows the viewer to press a button at any desired point during recording. A cue signal is recorded in response to.

Further, in the above-described embodiment, the fixed time is set to 30 minutes, but the fixed time can be arbitrarily set by operating the operation unit.

FIG. 2 is a block diagram showing a schematic configuration of main parts of another embodiment of the present invention, and parts corresponding to the embodiment of FIG. 1 are given the same reference numerals.

In the embodiment described above, the cueing signal is recorded at fixed time intervals based on the output of the recording time counter 4, but in this embodiment, either the output of the recording time counter 4 or the built-in clock 8 is used. A cueing signal is recorded at fixed time intervals by selecting one by operating an operation section (not shown). The other configurations are the same as those in the above embodiment.

<Effects of the Invention> As described above, according to the present invention, a video tape recorder equipped with a cueing function is provided with cueing signal recording means for sequentially recording cueing signals on the videotape at fixed time intervals during recording. Therefore, it is possible to perform a rough cue at fixed time intervals without performing any operations during recording, thereby making it easier to search for a desired scene.
