Abstract

본 발명은 디지탈 비디오 카세트 레코더(digital video cassette recoder)에 있어서, 특히 시간 압축되어 기록된 비디오 신호를 재생한 후 이를 시간 신장하는 시간 압축 주문형 비디오 카세트 레코더의 시간 신장 장치에 관한 것으로, 시간 압축된 비디오데이타를 시간 신장하여 MPEG 비트율로 변환하여 전송하는 시간 압축 주문형 비디오 카세트 레코더에 있어서; 상기 시간 압축된 비디오 데이터를 수신하여 이를 저장하기 위해 병렬로 구성된 다수개의 FIFO, 상기 다수개의 FIFO의 총 데이터 저장율에 따라 시간 압축된 비디오 데이터의 저장을 제어하고, 상기 다수개의 FIFO에 저장된 시간 압축된 비디오 데이터가 MPEG 비트율에 맞추어 출력되도록 제어하는 제어부(24)를 구비하여 구성함을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a time-decompression device of a time compression video cassette recorder, in which a digital video cassette recorder records a time-compressed video signal after reproducing a time-compressed video signal. A time compression on-demand video cassette recorder for time-expanding data, converting the data to an MPEG bit rate, and transmitting the data; A plurality of FIFOs configured in parallel to receive and store the time-compressed video data, controlling the storage of time-compressed video data according to the total data storage rate of the plurality of FIFOs, and time compression stored in the plurality of FIFOs And a control unit 24 for controlling the video data to be output in accordance with the MPEG bit rate.
