ITU-T H.239 (10/2014)

عربي | 中文 | English | Español | Français | Русский
Role management and additional media channels for ITU-T H.300-series terminals
Recommendation ITU-T H.239 defines the procedures for use of more than one video channel in ITU T H.320 based systems, and for labelling individual channels with a "role", which indicates requirements for processing the channel and the role of the channel content in the call. Role labels are applicable to both ITU T H.320 and ITU T H.245 signalling-based systems. The defined procedures include control, indication and capability exchange mechanisms
This revised version introduces a number of typographical corrections and clarifications to the previous version, primarily the description of MCU procedures.
