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 computer-readable medium storing a data structure for managing reproduction of at least video data having multiple reproduction paths, comprising:
- a data area storing a transport stream of the at least video data, the transport stream divided into transport packets, each of the transport packets associated with one of the multiple reproduction paths, and the transport packets of the multiple reproduction paths interleaved with each other; and
a navigation area storing navigation information for managing reproduction of the multiple reproduction paths recorded on the computer-readable medium, the navigation information including a first navigation unit and a separate map associated with each of the multiple reproduction paths, each of the separate maps providing position data for the video data associated with the corresponding reproduction path,wherein the first navigation unit includes one or more second navigation units and controls a reproduction order of the second navigation units, one of the second navigation units includes information for indicating a number of reproduction paths.

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.
