Multiple-description video coding based on JPEG 2000 MQ-coder registers

Wireless channels are more prone to transmission errors than wired communications counterparts, leading to excessive packet retransmission that is very inconvenient on media streaming. The multiple-description-coding (MDC) has proven to be very effective against transmission errors, thus providing a solution for that problem. What is presented is a method for MDC using the highly optimized and scalable JPEG 2000. Descriptions are encoded by our modified version of JPEG 2000 which produces compatible codestreams provided with key-error detection registers. The multiple-description JPEG 2000 decoder is then capable of precisely detecting transmission errors and to efficiently choose between available description-information, achieved by a clever exploitation of the EBCOT system. To test the potential of the proposed method, it is integrated as a spatial MD-Coder in a state-of-the-art joint-source channel video coder framework capable of an efficient bit-allocation between descriptions. A comprehensive set of experimental results is presented.
