Methods of processing an audiovisual signal that has a video portion and an audio portion are described. One example includes detecting a video synchronization event in the video portion and, in response to the detecting, embedding a marker relating to the video synchronization event into a serial data stream carrying the audio portion. The serial data stream includes a series of packets, each packet having (A) a preamble that includes a synchronization sequence, (B) an auxiliary data field, and (C) a main data field.
