This Recommendation specifies a packet-oriented multiplexing protocol for low bit rate multimedia communication. This protocol can be used between two low bit rate multimedia terminals, or between a low bit rate multimedia terminal and a multipoint control unit or an interworking adapter. The protocol allows the transfer of any combination of digital voice/audio, digital video/image and data information over a single communication link. This protocol provides low delay and low overhead by using segmentation and reassembly and by combining information from different logical channels in a single packet. The control procedures necessary to implement this multiplexing protocol are specified in Recommendation H.245.
