Abstract

본 발명은 VCR의 영상/음성정보 신호의 히스토리장치 및 제어방법에 관한 것으로 현재 시각을 전후한 일정시각 동안의 영상/음성 정보를 효율적으로 코드화하여 E2PROM에 저장하고 저장된 정보를 원래의 신호로 역부호화함으로써 현재 시각을 전후한 일정 시각동안, 즉 과거와 미래의 영상/음성정보를 저장하고 복원하는 히스토리장치 및 제어방법을 제공함에 그 목적이 있다. 본 발명은 상기 목적을 달성하기 위해 영상신호와 음성신호를 양자화하는 양자부(5), 양자화된 신호를 압축시키는 인코더(6), 압축된 영상/음성정보를 저장하는 메모리(7), 메모리(7)에 저장된 압축 영상/음성정보를 복원시키는 디코더(8), 압축 복원된 영상/음성정보를 역양자화시키는 역양자부(9), 역양자부(9)의 출력을 제어하는 스위치(S1,S2), 히스토리 영상/음성정보를 릴레이할 수 있는 히스토리 지정키(K1), 상기 메모리(7)에 저장된 영상/음성정보를 영구적으로 저장할 수 있는 히스토리 저장키(K2), 시스템을 제어하는 마이콤(10)으로 구성하고, 영상신호와 음성신호를 양자화하고 압축하여 저장하는 제 1 단계(100,101,102), 저장된 영상/음성정보를 압축 복원하고 역양자화시켜 출력하는 제 2 단계(103,104,105,106)로 이루어짐을 특징으로 한다.The present invention stores video / audio information for a predetermined time before and after the current time by efficiently encoded in the E 2 PROM on the history device and a control method of a video / audio information signal from the VCR, and the stored information back to the original signal It is an object of the present invention to provide a history apparatus and a control method for storing and restoring video / audio information of a past and future time, that is, before and after the current time by decoding. The present invention provides a quantum unit 5 for quantizing a video signal and an audio signal, an encoder 6 for compressing a quantized signal, a memory 7 for storing compressed video / audio information, and a memory ( Decoder 8 for restoring compressed video / audio information stored in 7), inverse quantum unit 9 for inverse quantization of decompressed video / audio information, and switch for controlling output of inverse quantum unit 9 (S 1). , S 2 ), a history designation key (K 1 ) capable of relaying history video / audio information, a history storage key (K 2 ) capable of permanently storing video / audio information stored in the memory 7, and a system. A first step (100, 101, 102) for quantizing, compressing and storing the video signal and the audio signal, and a second step (103, 104, 105, 106) for compressing, restoring and inversely quantizing and outputting the stored video / audio information. Characterized in that made.
