Video cassette recorder for and method of performing high-speed searching of important information, such as desired time or alarm data
A VCR for performing a high-speed searching process includes: a video signal input for outputting a video signal sent from a plurality of photographing sections; an encoder for encoding channel information and time information relative to the video signal, and for adding the encoded information to the vertical blanking interval of the video signal; a recording/reproducing section for recording the signal composed by the encoder and reproducing the recorded video signal; a decoder for extracting the channel information and time information inserted by the encoder from video signals outputted from the reproducing section, and for decoding them; a controller for inverting a control pulse at predetermined time intervals when the video signal is recorded to record a point in time within the predetermined time intervals, for searching the recorded point in time within the predetermined time intervals in a high-speed mode based on the channel information and time information transmitted from the decoder when automatic searching is performed during reproduction, and for converting the mode of the VCR into a standard mode, starting from the searched point in time, when a desired point in time has been searched; and a video signal output for externally outputting the video signal sent from the reproducing section.
