A method and system for splicing a first and a second compressed digital video bit stream, the first having a plurality of entry points, includes associating with each entry point an associated threshold buffer fullness such that if an actual video buffer verifier (vbv) fullness, just before removal of the bits of a first picture following the entry point equals or exceeds the associated threshold fullness, the portion of the first compressed digital bit stream following the entry point may be decoded without causing the vbv to underflow. Using an encoder, the second compressed digital video bit stream is generated. The second compressed digital video bit stream results in an ending fullness of a vbv one picture time after removal of the bits corresponding to a last picture of the second compressed digital video bit stream. This ending fullness equals or exceeds the threshold fullness associated with one of the entry points.

This application is a divisional of U.S. patent application Ser. No. 08/987,495, entitled "COMPRESSED VIDEO EDITOR WITH TRANSITION BUFFER MATCHER" by Elliot N. Linzer, filed on Dec. 9, 1997, now U.S. Pat. No. 6,301,428.
An optical disc, as an information recording medium for storing map audio object recorded on the optical disc in a constant bit rate format or a variable bit rate format and a recording position on the disc, can reduce a size of the map information. The map information stored in the optical disc records a playback duration for only first and last units of a plurality of audio object units (AOBU) comprised in an audio object (AOB) for each AOB when audio data in the variable bit rate mode is to be recorded, and records the sizes and playback duration of the AOBU for the last one of AOBUs comprised in AOB and for any one of the AOBUs except for the last AOBU.
A method and system for determining and recording a minimal ending video buffer verifier fullness at each of a plurality of entry points in a compressed variable bit rate video bit stream.
