Abstract:
A data transmission system comprising:data supply means operable with a first recording medium for storing source audio data, source video data and time code information attached to the source video data, wherein the time code information is associated with each video frame of said source video data; encoding means for generating an encoded stream having a first audio stream encoded in accordance with a moving pictures expert group (MPEG) standard, a second audio stream encoded in accordance with a standard different from the MPEG standard, and a plurality of layers generated by encoding the source video data, and for describing the time code information attached to each frame of the source video data into a picture layer among said plurality of layers; transmission means for transmitting the encoded stream; decoding means for decoding the encoded stream transmitted through the transmission means and extracting the time code information from the picture layer of the encoded stream by parsing the syntax of the encoded stream; and data recording means for recording the data decoded by the decoding means and the time code information extracted by the decoding means in a manner associated with each other onto a second recording medium so as to obtain the same data as on the first recording medium.
