Abstract
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.
Claims3
A method for encoding a sequence of video pictures to generate an encoded digital video bit stream comprising the steps of:
- (a) encoding each picture in said sequence to generate a portion of said digital video bit stream,
- (b) for each picture in said sequence, determining a minimum decoder buffer fullness needed by a decoder before removing said portion of said digital video bit stream corresponding to the picture from a decoder buffer so as to avoid said decoder buffer underflowing, and
- (c) storing in a storage medium each of said minimum decoder buffer fullness determined in step (b).
An encoding system for encoding a sequence of video pictures to generate an encoded digital video bit stream comprising:
- (a) an encoder for encoding each picture in said sequence to generate a portion of said digital video bit stream,
- (b) a processor for determining for each of a plurality of pictures in said sequence a minimum decoder buffer fullness needed by a decoder before removing said portion of said digital video bit stream corresponding to the picture from a decoder buffer so as to avoid said decoder buffer underflowing, and
- (c) a storage medium for storing each of said minimum decoder buffer fullnesses.
