[Component] H.225.0 [Description] 
This standard defines a layer that formats the transmitted video, audio, data, and control streams for output to the network and retrieves the received video, audio, data, and control streams from the network. H.225.0 uses the packet format specified by IETF RTP and RTCP specifications for logical framing, sequence numbering, and error detection as part of audio and video transmissions. Support for RTP and RTCP enables the receiving node to synchronize the received packets in the proper order so the user hears or sees the information correctly.
