In particular, a broadcasting station carries a recognition signal for important information (e.g., emergency news) and transmits the recognition signal. The present invention relates to an automatic recording control device for televideo when detecting important information that enables televideo to be automatically turned on to a corresponding broadcasting channel and to automatically record and record important information.

Currently, a commonly used video cassette tape recorder (hereinafter referred to as a VCR) reads image information recorded on an image information recording surface of an information recording medium such as a video tape and outputs an image on a CRT of a television as a video signal. In addition to performing an image reproducing operation for outputting, receiving a television broadcasting signal according to a television broadcasting program of a predetermined channel, processing an image signal and an audio signal, and then recording information of a recording head such as a video tape. The video recording operation for recording the video signal and the audio signal on the image is also performed.

A VCR equipped with such a video playback function and a video recording function can be viewed through a key input operation of a key matrix provided in a remote control or a control panel of the VCR when a user wants to watch a television program of a predetermined channel to be used in the absence. When the channel number, reservation date, and reservation time of the desired television broadcasting program are set, the television broadcasting signal of the desired television broadcasting program of the predetermined channel is transmitted to the tuner built into the VCR as the set reservation date and reservation time elapse. By the recording operation of the recording head so that the recording is recorded on the information recording surface of the information recording medium. My timer is showing the correct current time In view of the problem that when the time indicated by this timer does not coincide with the current time, accurate reservation recording of the TV broadcast program is impossible, the current time of the remote controller is transmitted at the time of performing the reserved recording operation. When there is a key input operation, the time recording function of the timer of the video device is automatically corrected to the correct current time.

In addition, the video tape applied to the recording of a specific video / audio program and the playback of the recorded video / audio program using magnetic properties is a reel of a hard case, commonly referred to as a 'video cassette'.
