APPARATUS AND METHOD FOR MINIMIZING VIDEO MEMORY OF DIGITAL TIME LAPSE VCR

摘要

PURPOSE: An apparatus for minimizing a video memory of a digital time lapse VCR(video cassette recorder) is provided to reduce the capacity of a video memory necessary for recording/playing back a video signal by saving a compressed video signal in the video memory. CONSTITUTION: A frame memory saves a video signal per field according to a predetermined recording interval cycle. A compression unit(106) compresses the video signal read from the frame memory at a predetermined compression rate. A video memory saves the video signal saved in the frame memory sequentially. A memory control unit outputs the video signal of the frame memory to the compression unit and saves the video signal in the video memory, Then, the memory control unit records the video signal of the video memory on a video tape by reading the video signal sequentially.
