Terminal for low bit-rate multimedia communication
|Publication Date:||1 April 2009|
This Recommendation covers the technical requirements for very low bit-rate multimedia telephone terminals operating over the general switched telephone network (GSTN).
ITU-T H.324 terminals provide real-time video audio or data, or any combination, between two multimedia telephone terminals over a GSTN voice band network connection. Communication may be either 1-way or 2-way. Multipoint communication using a separate multipoint control unit (MCU) among more than two ITU-T H.324 terminals is possible. MCUs and other non-terminal devices are not bound by the requirements in this Recommendation, but they should comply where practical.
The multimedia telephone terminals defined in this Recommendation can be integrated into personal computers (PCs) or workstations, or be stand-alone units.
Interworking with visual telephone systems on the integrated services digital network (ISDN) (known as the ITU-T H.320-series of Recommendations) and on mobile radio networks are also covered.
