<p>C:NRPonbl/DCC/KXANW45371_.DOC-12/12/2011 Systems and methods for error resilient transmission, rate control, and random access in video communication systems that use scalable video coding are provided. Error resilience 5 is obtained by using information from low resolution layers to conceal or compensate loss of high resolution layer information. The same mechanism is used for rate control by selectively eliminating high resolution layer information from transmitted signals, which elimination can be compensated at the receiver using information from low resolution layers. Further, random access or switching between low and high resolutions is also 10 achieved by using information from low resolution layers to compensate for high resolution spatial layer packets that may have not been received prior to the switching time.
