This includes improvement of the clock reference stream format, enlargement of the AVTP sequence number to increase rollover time for high-speed streams, enlargement of the CAN and LIN bus IDs to support more buses, enhancement for tracking grandmaster clock changes, larger presentation time intervals, clarification of clock stability information, and guidance on how to handle the out-of-order arrival of AVTP PDUs that often occurs when transmitting data on redundant paths.
