Abstract
In one embodiment, a method includes receiving at a multimedia transformation unit, media streams from a plurality of endpoints, transmitting audio components of the media streams to a multipoint conferencing unit, receiving an identifier from the multipoint conferencing unit identifying one of the media streams as an active speaker stream, processing at the multimedia transformation unit, a video component of the active speaker stream, and transmitting the active speaker stream to one or more of the endpoints without transmitting the video component to the multipoint conferencing unit. An apparatus is also disclosed.
Claims20
A method comprising:
- receiving at a multimedia transformation unit, media streams from a plurality of endpoints;
- transmitting audio components of said media streams to a multipoint conferencing unit;
- receiving an identifier from the multipoint conferencing unit identifying one of said media streams as an active speaker stream;
- processing at the multimedia transformation unit, a video component of said active speaker stream;
- and
- transmitting said active speaker stream to one or more of said plurality of endpoints without transmitting said video component to the multipoint conferencing unit.
An apparatus comprising:
- a processor configured to transmit media streams received from a plurality of endpoints to a multipoint conferencing unit, receive a plurality of redundant streams from the multipoint conferencing unit, decode two or more substreams generated from the redundant streams, identify a failure of one of said substreams, and utilize another one of said substreams in place of said failed substream;
- and
- memory for storing a redundancy parameter corresponding to a number of said substreams decoded at the apparatus.
An apparatus comprising:
- an interface for receiving media streams from a multimedia transformation unit, said media streams transmitted from a plurality of endpoints;
- and
- a processor for interconnecting said plurality of endpoints in a conference session;
- wherein the processor is configured for offsetting delivery of packets to the multimedia transformation unit to decorrelate channels at the multimedia transformation unit.
