Abstract
In order to loop MPEG2 bitstreams without violating buffer occupancy constraints of downstream decoders, the replay bit rate is modified so the time taken to replay the looped sequence is made equal to the decode time. Looping of a sequence of compressed video bitstream is used for the purpose of testing MPEG2 decoders.
