Abstract

A set top box can be connected to a DVD Streamer via an IEEE1394 interface which contains means to timestamp data and to strip off these timestamps again, using them for timing regeneration. The DVD stream also must regenerate the timing of data packets as it was upon recording, when these packets are played back. The streamer could also use its own timestamps and strip them off again when replaying. So, in total, there is an in-series connection between two time stamping and time regeneration mechanism which introduces jitter accumulation.
