Method and apparatus of recording a multi-channel stream, and a recording medium containing a multi-channel stream recorded by said method
First Claim
1. A method of recording a multi-channel on a recording medium, comprising the steps of:
- (a) recording a multi-channel stream composed of substreams belonging to a plurality of channels and unitizing the recorded stream to a single stream object; and
(b) creating search information for each substream contained in the recorded multi-channel stream unitized to the single stream object and recording the created search information on a recording medium.

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 on a recording medium, unitizes the recorded stream to a single stream object, 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.
