Multi-angle digital and audio synchronization recording and playback apparatus and method

Abstract

A digital video playback apparatus selectively reproduces video signals which are recorded by using a plurality of cameras each at different angles and method therefor. A digital playback apparatus reads out first and second video steam data and first and second audio stream data, which are compressed and recorded on a recording medium. A demultiplexer separates a signal output of the digital playback apparatus into system information, the first and second video stream data, and the audio stream data. First and second video decoders expand the first and second compressed video stream data outputs. An audio decoder decodes and expands the audio stream data outputs from the demultiplexer. A key input section generates first and second angle selection signals. A controller analyzes the system information, and generates a switching control signal and a plurality of delay time and gain control signals. A switch selects the first and second video stream data according to the switching control signal. A delay time and gain control circuit delays the audio stream data outputs from the audio decoder according to the delay time control signals, and controls gains of the delayed audio stream data according to the gain control signals.
