Abstract

본 발명은 데이타의 기록효율의 증진을 도모하고, 어드레스를 가지며 랜덤 억세스가 가능한 기록매체에서 재생시의 특수기능에 따라 필요한 데이타를 쉽게 억세스할 수 있도록 한 것으로서, 영상신호의 부호화된 비트열을 프레임내 부호화하여 메모리수단에 기록하는 디지탈 영상기록장치에 있어서, 프레임내 부호화된 영상데이타 신호의 비트열과 프레임 데이타의 시작 및 끝 어드레스가 각각의 메모리에 기록되므로서, 시작 및 끝 어드레스가 기록된 메모리로부터의 어드레스신호에 의거하여 비트열 기록 메모리에 기록되어 있는 프레임 데이타가 순차적으로 판독되도록 한 것이다.The present invention aims to improve the recording efficiency of data, and to easily access necessary data according to a special function at the time of reproduction in a recording medium having an address and random access. In a digital video recording apparatus for encoding and recording in a memory means, the bit strings of intra-frame coded video data signals and the start and end addresses of frame data are recorded in respective memories, whereby the start and end addresses are recorded from the memory. Based on the address signal, frame data recorded in the bit string recording memory is read out sequentially.
