Abstract
A digital recording and playback apparatus adopting an MPEG encoder and decoder, and a method thereof. The digital recording and playback apparatus includes: a first encoder for coding input video data in picture units, and outputting coded video data; a second encoder for coding input audio data and outputting coded audio data; a packetized elementary stream (PES) packetizer for packetizing the coded video data and audio data and user data into each PES, and outputting a video PES, audio PES and user PES; and a transport stream (TS) packetizer for multiplexing the video PES, audio PES and user PES into a TS. The digital recording and playback apparatus can be compatible with a digital television or multimedia applications adopting the MPEG standard, and can perform editing in picture units as well as high-speed search.
