摘要:
A method and apparatus for creating and recording management information for digital data streams by grouping transport stream units of a received transport stream into stream object units so that the maximum search time required for locating a specific position within a stream object unit is uniform among a plurality of stream object units. An example embodying the present invention varies the time length of each stream object unit depending upon the bit rate of the received transport stream and keeps the size of each stream object unit constant irrespective of the transfer rate of the data stream, thereby guaranteeing the maximum search time required for locating a transport stream packet within a stream object unit to be uniform.

According to an embodiment, a method of recording a digital stream on a recording medium, includes determining one of at least two recording modes to record a transmitted digital stream, wherein a first recording mode is to record data based on entry point information present in the digital stream and a second recording mode is to record data on a basis of a predetermined time; and recording the digital stream based on the determined recording mode, and recording a mode information indicating the determined recording mode.
摘要:
A method and apparatus for recording received digital data streams on a recording medium such as a digital video disk and creating and recording management information pertaining to the recorded digital data streams. Random access information contained in the received digital data streams is detected and stream object units are created based upon the detected random access information, which enables reproduction of recorded data to start from the transport stream packet having the random access information and prevents imperfect data reproduction after track seek or time seek operations.
