Title: ADDING AUDIO-VISUAL DATA TO PREVIOUSLY RECORDED AUDIO-VISUAL DATA ON DISK MEDIUM
Abstract:
A method for configuring a recordable medium to store subsequently added data to previously recorded multiplexed audio-visual data can include multiplexing original audio-visual data and navigation data into a composite data stream; recording the composite data stream to packs in a recordable medium; further recording reserved packs in the recordable medium; and, subsequently recording supplemental data corresponding to the original audio-visual data in the reserved packs. The method can further include designating the recorded reserved packs as able to accept subsequently recorded supplemental data; and, subsequent to recording supplemental audio-visual data in the reserved packs, re-designating the reserved packs according to whether the reserved packs contain supplemental sub-picture, audio or video data. Notably, the first three steps of the method can occur in an initial recording session while the fourth step can occur in an editing session. Alternatively, all of the steps can occur in a single recording session.
