Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video tape recorder (hereinafter referred to as VTR) having a recording function,
This is effective for simultaneously recording the reduced version of the program and the entire program from the start to the end in order to grasp the contents of the program in a short time.

[0002]

2. Description of the Related Art In recent years, media such as satellite broadcasting and cable television have become widespread, and the frequency of use of VTRs has increased accordingly. On the other hand, reflecting the busy society, there are some voices of VTR users saying that there is no time to watch a broadcast even if it is recorded. Therefore, recently, there is a tendency that a program of interest is recorded by a timer recording function for the time being, and a program recorded later is selectively viewed. At this time, as a method of confirming the content of the recorded program in a short time when selecting a program to be watched, firstly, the recorded content is quickly viewed without audio in fast-forward reproduction (hereinafter abbreviated as CUE). Secondly, if the VTR is capable of audio reproduction at a speed such as 2x speed, these functions can be utilized by repeating fast-forwarding (hereinafter abbreviated as FF) and reproduction to watch the program fragmentarily. to see,
The method such as is conceivable. Fourthly, in a VTR having a time-lapse shooting function, there is a method of time-lapse shooting of a program and reproducing it later to watch it in a short time. As for the time-lapse function,
There are one that repeats the operation of recording a television signal for several frames and then stopping and recording several frames, and another called time-lapse video that intermittently records the television signal one frame or one field at a time.

[0003]

The problem with the conventional method for confirming the contents of a program recorded in a short time is that the first method using the CUE does not reproduce the audio signal, and thus the fast-forward video is not reproduced. Can only be confirmed visually. Also, there is a limit to the CUE speed, and it takes 12 minutes to check a program for 1 hour at 5 times speed, for example, and it is hard to say that it can be checked in a short time. In the method in which the second user repeatedly performs the FF operation and the reproduction operation, the signal is normally reproduced in both video and audio, but the repetition operation is troublesome. Third
With the method of using a VTR equipped with a high-speed playback function such as 2 × speed playback, it is still unnatural to the normal sense of human being, although no noise is found in the image and the voice is easily heard. Further, as in the case of the first method, it takes 30 minutes to confirm a program of 1 hour at double speed. In the fourth method, the sound is recorded only in pieces, so that it is difficult to confirm auditorily. Also, if the user confirms the contents, there is no tape that records everything at a normal speed, so that there is a big problem that he cannot do it even if he wants to watch the whole program.

An object of the present invention is to solve the above-mentioned problems, and when confirming the contents of a program in a short time, a reduced plate tape in which the program is fragmentally recorded is reproduced in a good state of video and audio. However, if the program is a favorite, a VTR that allows the user to watch the program by playing back a tape recording the beginning to the end of the program is provided.

[0005]

In order to achieve the above-mentioned object, the present invention provides a first video tape recorder having an information sending means for sending information regarding the operating state of recording and stopping of the video tape recorder to the outside. A second video tape recorder comprising: an information receiving means for receiving information sent from the first video tape recorder by the information sending means; and a system control means for controlling the operation of the video tape recorder such as recording and stopping. The first video tape recorder operates by the information sending means to send the information of the recording operation state at the start of recording and the information of the stop state at the end of the recording, and the second video tape recorder has the system controlling means. Receives the information of the recording operation state of the first video tape recorder and then the information of the stop state by the information receiving means. Until then, the recording / stopping operation is repeated at a preset time interval, and the second videotape recorder further comprises an input means for inputting the recording / stopping time interval, which is input by the input means. The recording and stopping operations are repeated at a set time interval.

[0006]

With the above structure, the VTR of the present invention records all the programs in the first VTR in order to improve the problem when confirming the contents of the programs recorded in the conventional VTR in a short time. The second VTR detects the start and end of recording of the first VTR, and during the recording period of the first VTR, recording and stopping operations are repeated at preset time intervals or at intervals set by the user. When checking the contents of the program by time, play the tape recorded on the second VTR,
If the user likes the program, the tape recorded by the first VTR can be reproduced to watch the entire program.
