Embedded Clock Recovery

Abstract

Systems and methods and computer program products are disclosed to determine the source data rate even in cases where the sink device is not directly coupled to the source device. A method includes, forming a logical channel from a source device to a sink device where the logical channel is configured to carry the source data stream and one or more rate parameters. The rate parameters relate a data rate of the source data stream to a data rate of the logical channel. Another method includes, detecting a logical channel in a received data stream where the logical channel includes the source data stream, recovering one or more rate parameters from the received data stream, determining a data rate of the logical channel, and determining the data rate of the source data stream based on the data rate of the logical channel and the one or more rate parameters.
