DIGITAL VIDEO AND DATA RECORDER

摘要

An apparatus (22) for recording one or more sessions fom one or more streams of interframe compressed audiovideo data which has been synchronized to a reference clock (23a). The invention adds special splice point indicators (23b) to recorded video material. Splice point indicators (23b) are used to determine the existence of a point of discontinuity in the recorded audiovideo data. The system enables pausing and later resuming recording of an audiovideo data stream such that the audiovideo data can be played back with proper resynchronization at each point of discontinuity. The system also allows for recording an abrupt change from one audiovideo data stream to a different audiovideo data stream having a different clock reference (23a).
