Information recording medium a wherein stream convertible at high-speed is recorded, and recording apparatus and recording method therefor

摘要

An information recording medium wherein a stream which is recorded in a constrained format allowing format conversion from a first format (MPEG-TS) to a second format (MPEG-PS) and is seamlessly connected, can be converted into a second stream, and an apparatus and method for recording information in the information recording medium. The constrained format is provided for enabling conversion from a first format (for example, MPEG transport stream) to a second format (for example, MPEG program stream). Seamless playback is performed by using a third system stream (Bridge-VOB), which is composed of each of the parts the two seamlessly connected system streams. A video information presentation time by data management unit (Capsule) at the beginning of the third system stream is greater than or equal to 0.4 and less than or equal to 1 second, according to the constrained format.
