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 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; and
(b) creating search information for each substream contained in the recorded multi-channel stream in 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 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.

17. 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 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; and
(b) creating a single piece of search information and as many pieces of cell information as the number of channels for all substreams of the recorded multi-channel stream in the single stream object and recording the created search information and cell information on a recording medium.

18. An apparatus of recording a multi-channel on a recording medium, comprising:
-
a data receiver receiving at least one RF channel of a digital broadcast signal to output a multi-channel stream composed of substreams belonging to selected plural sub-channels; and
a recording means recording the multi-channel stream 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, creating search information for each substream contained in the recorded stream, and recording the created search information on the recording medium.

24. A recording medium for recording digital data stream, comprising:
-
a single stream object in which a multi-channel stream composed of substreams belonging to a plurality of channels has been recorded, the recorded multi-channel stream consisting of successive data blocks which are interleaved each other by channel;
plural pieces of search information created for each of the substreams contained in the stream object; and
at least one piece of program information and at least one piece of cell information created for the multi-channel stream in the single stream object.
