METHOD FOR GENERATING ADDITIONAL INFORMATION FOR SECURING CONTINUOUS REPRODUCTION BETWEEN DATA STREAMS

摘要

PURPOSE: A method for generating additional information is provided to secure continuous reproduction between data streams after recording plural data streams of packet data type in a recording medium. CONSTITUTION: SOBI(stream object information) includes a continuous playback information and a continuous time control information. The continuous playback information contains a value representing a seamless playback or a seamy playback. And, the continuous time control information includes a reference time, an offset, and a gap length. When the continuous playback information represents the seamless playback, the continuous time control information is effective. Herein, the continuous time control information represents the precise output time of an SOB2 ensuring the seamless playback at the boundary of an SOB1 and the SOB2. The continuous time control information uses the reference time or the offset between an ATS(arrival time stamp) corresponding to the reference time and an original ATS. The continuous time control information uses the gap length resetting a counter after outputting the last packet of the SOB1 as the arrival time of the first packet in the SOB2.
