<p>A digital video playback apparatus (42) selectively reproduces video signals which are recorded by using a plurality of cameras at different angles. A digital playback apparatus (42) reads out first and second video stream data and first and second audio stream data, which are compressed and recorded on a recording medium. A demultiplexer (44) separates a signal output of the digital playback apparatus (42) into system information, the first and second video stream data and the first and second audio stream data. First and second video decoders (46,48) expand the first and second compressed video stream data outputs. First and second audio decoders (50,52) decode the first and second audio stream data outputs from the demultiplexer (44) and expand the first and second audio stream data decoded into original 4-channel audio signals, respectively. A key input section (64) generates first and second angle selection signals. A controller (62) analyzes the system information and generates a switching control signal. First and second switches (54,56) selects the first and second video and audio stream data according to the switching control signal.</p> |
