Abstract:
1. An encode apparatus for encoding an input video signal and an input audio signal into a video object, the encode apparatus 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; a multiplexer operable to multiplex the generated video stream, the first audio stream, and the second audio stream to generate a video object; a controller operable to control the video stream generator, the audio stream generator, and the multiplexer, wherein the audio stream generator is operable to generate the first audio stream to include a plurality of packs having a fixed size, and to generate the second audio stream by using audio data to be contained in the packs of the first audio stream, so that the second audio stream has a same bit rate as the first audio stream and includes a same number of packs as the first audio stream, the packs of the second audio stream having the same size as the packs of the first audio stream, and each pack of the first and second audio streams has identification information for identifying which one of the first and second audio streams includes the pack.
