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

A digital video playback apparatus to read out first and second video stream data and audio stream data which are compressed and recorded on a recording medium, the digital video playback apparatus comprising:

• a digital playback apparatus to read out the compressed first and second video steam data and the compressed audio stream data, from the recording medium and to error-correct and deinterleave the first and second video data and the audio stream data;
• a demultiplexer to separate a signal output of said digital playback apparatus into system information, the compressed first and second video stream data recorded from a plurality of different angles, and the compressed audio stream data;
• first and second video decoders to expand the first and second compressed video stream data outputs from said demultiplexer, respectively;
• an audio decoder to decode and expand said compressed audio stream data output from said demultiplexer into 4-channel audio stream data;
• a key input section to generate first and second angle selection signals;
• a controller to analyze the system information from the demultiplexer, and to generate a switching control signal indicative of one of the first and second video stream data from said first and second decoders, respectively, a plurality of delay time control signals, and a plurality of gain control signals, in response to one of the first and second angle selection signals selected by a user at said key input section;
• a switch to select one of the first and second video stream data from said first and second video decoders, respectively, according to said switching control signal;
• and
• a delay time and gain control circuit to delay the 4-channel audio stream data outputs from the audio decoder according to the plurality of delay time control signals, and to control gains of the delayed 4-channel audio stream data according to the plurality of gain control signals.
