Abstract
A method of processing a video transport stream includes receiving a video transport stream and identifying at least one portion of the video transport stream that is not to undergo modification when processed by a rate shaping device. An indicator is inserted into the video transport stream. The indicator is used to signal the statistical multiplexer that the at least one portion of the video transport stream is not to be modified when the video transport stream is processed by the rate shaping device.
