Abstract
The invention is a method and apparatus for processing an MPEG-like bitstream comprising information frames having associated timing parameters. The method and apparatus identify one or more non-referential information frames containing at least a threshold number of bits, remove one or more of the identified non-referential information frames and modify the timing information associated with each information frame following the one or more removed information frames.
