Abstract:
An optical disc recording apparatus for recording an input video signal and an input audio signal onto an optical disc, comprising:a video stream generator operable to generate a video stream by encoding the video signal; an audio stream generator operable to generate a first audio stream by encoding the audio signal, and to generate a second audio stream for dubbing based on the generated first audio stream, such that the second audio stream is capable of being subsequently dubbed with audio data whose contents differ from the first audio stream; a multiplexer operable to multiplex the generated video stream, first audio stream, and second audio stream to generate a video object; a recording means for recording the video object onto the optical disc; and a controller operable to control the video stream generator, the audio stream generator, the multiplexer and the recording means, wherein the audio stream generator generates the first audio stream so as to include a plurality of packs having a fixed size, and generates the second audio stream so as to have the same bit rate as the first audio stream and so as to include the same number of packs as the first audio stream, and such that each pack has the same size as a pack of the first audio stream, and the controller respectively provides the first audio stream and the second audio stream with identification flags for identifying the associated audio streams and controls the recording means to record the identification flags onto the optical disc.
