PROBLEM TO BE SOLVED: To provide desirable scalable codec solutions in videoconferencing by enabling zero-delay MCU architectures that allow cascading of MCUs in electronic networks with no or minimal end-to-end delay penalties.SOLUTION: Scalable video codecs are provided for use in videoconferencing systems and applications hosted on heterogeneous endpoints/receivers and network environments. The scalable video codecs provide a coded representation of a source video signal at multiple temporal, quality, and spatial resolutions. |
