PCR jitter reduction in a VSB and/or EVSB multiplexer system

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 recovered MPEG data stream comprises first and second MPEG data streams, wherein the recovering of the MPEG data stream from the signal comprises recovering the first and second MPEG data streams from the signal, wherein the reading of the re-stamped program clock references in the MPEG data stream comprises reading re-stamped program clock references in the first and second MPEG data streams, and wherein the processing of the MPEG data stream in accordance with the re-stamped program clock references comprises processing of the first and second MPEG data streams in accordance with the re-stamped program clock references,
• wherein the original program clock references are designated original_PCRn, wherein the re-stamped program clock references are designated restamped_PCRn, wherein n comprises an integer, wherein a delayed_PCRn comprises the sum of the original_PCRn and the delay, wherein, for n=1, the restamped_PCRn comprises the original_PCRn, and wherein, for n>1, the restamped_PCRn comprises restamped_PCRn−1+(delayed_PCRn−delayed_PCRn−1).

A method of receiving first and second MPEG data streams, wherein the first MPEG data stream includes first re-stamped program clock references, wherein the first re-stamped program clock references in the first MPEG data stream comprise corresponding first original program clock references re-stamped in accordance with a first variable delay, wherein the second MPEG data stream includes corrected program clock references, wherein the corrected program clock references in second MPEG data stream comprise corresponding second re-stamped program clock references corrected in accordance with a fixed delay, wherein the second re-stamped program clock references comprise corresponding second original program clock references re-stamped in accordance with a second variable delay, the method comprising:

• recovering the first and second MPEG data streams from the signal;
• reading the first re-stamped program clock references in the first MPEG data stream;
• processing the first MPEG data stream in accordance with the first re-stamped program clock references;
• reading the corrected program clock references in the second MPEG data stream;
• and,
• processing the second MPEG data stream in accordance with the corrected program clock references.
