Each user control style is selectable by a user and is configured to change at least one of region presentation properties specified by a corresponding region style.

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 separates a multi-channel stream composed of substreams belonging to a plurality of channels into individual substreams, records the individual substreams separately by channel in a single or plural stream objects allocated in a recording medium, and creates as many files as the number of channels for the single or plural stream objects. The present method makes it possible to selectively search and reproduce each substream among a recorded multi-channel stream through file selection, thereby improving use convenience of a recording machine such as a digital video recorder.

Abstract: In the data structure, a data area of the recording medium stores a transport stream of at least video data. The transport stream is divided into transport packets, and each of the transport packets is associated with one of the multiple reproduction paths. Also, the transport packets of each reproduction path is stored in separate physical domains of the data area from one another.

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.

Abstract: In the data structure, a data area of the recording medium stores at least video data as a transport stream in more than one file. Each file is associated with a different one of the multiple reproduction paths, and the files are interleaved with one another.

Abstract: The present invention provides a recording medium, reproducing method thereof and reproducing apparatus thereof. The present invention includes a text subtitle stream including at least one dialog presentation segment (DPS) and one dialog style segment (DSS) and a clipinfo file (*,clpi) as reproduction management information to reproduce the text subtitle stream, wherein map information mapped to a dialog presentation segment (DPS) within the text subtitle stream is recorded in the clipinfo file.

Abstract: A recording medium, and a method and apparatus for reproducing data from the recording medium are disclosed. The recording medium for recording data includes: first reproduction-restriction information of the recording medium; and update information of second reproduction-restriction information of other recording medium. If the content provider (CP) desires to release reproduction-restriction of pre-introduced content data at a region or country due to the reproduction environment or other conditions associated with the data reproduction, the content provider provides reproduction-restriction release information via new recording medium including other contents. The user can buy the new recording medium and receive restriction release information from the content provider (CP) without paying the usage fee of reproduction-restricted contents, thereby freely employing desired contents having been protected from being reproduced.
