CLOCK RECOVERY IN TRANSPONDER-BONDED SYSTEMS USING BCRs AND MARKER PACKETS AT A SET-TOP BOX

摘要

A transponder-bonded receiver system with clock recovery may include memory an and one or more processors coupled to the memory and configured to execute one or more program modules to perform: receiving multiple data streams each including a number of data packets, and a number of marker packets with embedded bonding clock references (BCRs) and including marker packet information; adjusting arrival-time-stamps (ATSs) of the marker packets by using the BCRs and including capturing timing between the marker packets based on a local free running counter of the receiver; and determining an adjusted ATS corresponding to an ATS at the receiver for each of the plurality of packets using the ATS and a delta-ATS.

1. A method for clock recovery in a transponder-bonded system, the method comprising:
receiving, at a receiver, a plurality of data streams, each data stream comprising a plurality of marker packets including marker packet information, wherein bonding clock references (BCRs) are embedded in the marker packet information; and adjusting arrival-time-stamps (ATSs) of the plurality of marker packets using the BCRs, wherein adjusting the ATSs of the plurality of marker packets include capturing timing between the plurality of marker packets based on a local free running counter of the receiver.
