ABSTRACT:
The present invention relates to method and apparatus of recording a multi-channel data stream on a recording medium in such a manner that substreams of digital channels constituting the multi-channel data stream can be distinguished each other in reproduction. The present recording method records a multi-channel stream composed of substreams belonging to plural selected channels in a single stream object while grouping every partial stream of same channel to a data block and interleaving the data blocks of different channels each other, creates a piece of search information for each substream contained in the recorded multi-channel stream, and records the created plural pieces of search information on the recording medium. The present method makes it possible to selectively search and reproduce each substream among a multi-channel stream recorded on a recording medium, thereby improving use convenience of a recording machine such as a digital video recorder.
