PROVISION OF VIDEO CONFERENCING SERVICES USING REFLECTOR MULTIPOINT CONTROL UNITS (MCU) AND TRANSCODER MCU COMBINATIONS

摘要

Embodiments are described for provision of video conferencing with reflector MCUs, transcoder MCUs, and/or combinations thereof. In some embodiments, a protocol connector module of a video conference system receives information on multi-data stream composition capabilities of a client application for a participant endpoint device of a video conference, session state information is received for creation of a composite of received video conference data streams for presentation at the client application, and instructions are selectively sent for handling media processing for each of the received video conference data stream from other participant devices based on the received multi-data stream composition capabilities information of the client application

主权项

1. A method comprising:
receiving, at a protocol connector module of a video conference system, information on multi-data stream composition capabilities of a client application for a participant endpoint device of a video conference; receiving session state information for creation of a composite of received video conference data streams for presentation at the client application; and selectively sending instructions for handling media processing for each of the received video conference data streams from other participant devices based on the received multi-data stream composition capabilities information of the client application, wherein the selective sending of instruction for a received data stream comprises:
(1) if the client application is capable of multi-data stream composition for a communication protocol of the received data stream, the protocol connector module sends state information to a protocol connector module receiving the data stream from the other participant device; and
the protocol connector module sends instructions to the reflector multipoint control unit to forward the received data stream to the client application for creation of the composite of video conference data streams;(2) Otherwise, the protocol connector module sends instructions to the transcoder multipoint control unit, the transcoding instruction comprising at least one of:
a) transcode the received data stream in accordance with the state information and transcode the received data stream into a communication protocol the client application is capable of processing for creation of the composite; and send the transcoded data stream to the client application; andb) transcode the received data stream for creation of the composite of video data streams by the video conference system in accordance with state information that is sent to the client application.
