Modem front-end apparatus and method

A method and apparatus for recovering a second transport stream included within a first transport stream and reducing timing anomaly imparted to the second transport stream within the context of a front-end device subject to random access via a data bus, illustratively a PCI bus. A first transport stream is received from a transport medium, the first transport stream having disposed therein packets associated with a second transport stream. The first medium tending to impart jitter to the first transport stream. Those packets associated with the second transport stream are extracted from the first transport stream and adapted to reduce jitter, and launched via a second transport medium, the launched adapted packets forming a jitter-reduced second transport stream.
