Abstract
In one embodiment, a method includes synchronizing to a common reference timeframe between a sender node and a plurality of receiver nodes connected over a packet-based network. The sender node sends Real-Time Protocol (RTP) frames to the receiver nodes, and also sends a RTP Control Protocol (RTCP) sender report to each receiver node that contains a rendering offset value, each receiver node rendering the RTP frames at a render time equal to a sampling time in units of the common reference timeframe plus the rendering offset value. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.
