SYSTEM AND METHOD FOR A CONFERENCE SERVER ARCHITECTURE FOR LOW DELAY AND DISTRIBUTED CONFERENCING APPLICATIONS |
摘要 |
Systems and methods for conducting a multi-endpoint video signal conference are provided. Conferencing endpoints are linked by pairs of a reliable and a less reliable communication channel. Conference video signals are scaleable coded in base layer and enhancement layers format. Video signal base layers, which correspond to a minimum picture quality, are communicated over reliable channels. The video signal enhancements layers may be communicated over the less reliable channels. A conference server mediates the switching of video layer information from transmitting endpoints to receiving endpoints without any intermediate coding or re-coding operations. The video conference can be integrated with an audio conference using either scalable coded audio signals or non-scaleable coded audio signals.
