Patent ID: 7680155

Claim:
A method of receiving a signal having re-stamped program clock references in an MPEG data stream, wherein the re-stamped program clock references in the MPEG data stream comprise corresponding original program clock references re-stamped according to an amount of a delay caused by a buffer, the method comprising: recovering the MPEG data stream from the signal; reading the re-stamped program clock references in the MPEG data stream; and, processing the MPEG data stream in accordance with the re-stamped program clock references, wherein the original program clock references are designated original_PCR n , wherein the re-stamped program clock references are designated restamped_PCR n , wherein n comprises an integer, wherein a delayed_PCR n comprises the sum of the original_PCR n and the delay, wherein, for n=1, the restamped_PCR n comprises the original_PCR n , and wherein, for n>1, the restamped_PCR n comprises restamped_PCR n−1 +(delayed_PCR n −delayed_PCR n−1 ).
