Abstract
Synchronization of related packet data network streams is provided. Synchronization is achieved by inserting synchronization packets into data streams that are to be aligned with one another after transmission of those data streams across a network. More particularly, corresponding synchronization packets are inserted into the corresponding data streams at the same time, to serve as markers for performing synchronization of the data at the receiving end. The corresponding data streams may comprise an audio data stream and a corresponding video data stream.
