Abstract
A method for recovering clock signals includes generating a media sync signal to synchronize processing of digital media, and generating a transmission reference clock signal to define a duration of a transaction through a packet-based data network. The media sync and transmission clock signals may have different frequency and phase. The media is sent to a slave node of the network. The media sync and transmission clock signals are correlated to generate phase correlation information, and the phase correlation information is also sent to the slave node. Accordingly, a relatively low cost and reliable clock recovery technique suitable for synchronizing media streams across a packet-based data network is disclosed.
