Abstract

A system and method is provided for revising the time stamp information in an MPEG-2 transport stream after content in the transport stream is modified. According to one method, successive PCR time stamps previously added to the transport stream are used to determine PCR.sub.SYNC time stamps for synchronization points in the transport stream by interpolation. The PCR.sub.SYNC time stamps are substituted into transport packets within the transport stream. The PCR.sub.SYNC is also used to determine modified time of arrival (TOA) stamps to be added to transport packets. According to a second method, PCR interpolation is used to determine the values of PCR.sub.SYNC. TOA interpolation of TOA stamps previously added to the transport stream are used to determine modified TOA stamps to be substituted into the transport stream for the previously added TOA stamps.
