A timing synchronization method and apparatus for processing a compressed information stream comprising a plurality of information segments representative of a sequence of information frames. Information segments representative of information frames are deleted in response to an indicium of buffer overutilization.

[ What is claimed is:] [10.] A method of processing at least one compressed image stream to produce a compressed output information stream, each compressed information stream representing a respective sequence of compressed image frames, said output information stream being processed in a manner tending to avoid decoder buffer underflow and overflow conditions, said method comprising the steps of:receiving, via an input buffer, a first compressed information stream and providing a buffered information stream therefrom, said buffered information stream being further processed by a frame sequence adjuster to form a processed information stream;deleting, from said input buffer, at least one information frame in response to an input buffer utilization level exceeding a first threshold level;calculating a utilization level of a decoder buffer receiving said buffered information stream to provide a first calculated utilization level;deleting, using said frame sequence adjuster, at least one information frame from said buffered information stream in response to said calculated utilization level exceeding a second threshold level; andadding, using said frame sequence adjuster, at least one information frame to said buffered information stream in response to said calculated utilization level being below a third threshold level.
