Abstract :
The paper proposes a video communication scheme combing multiple description coding (MDC) using scalar quantizers with matching pursuit (MP) to transmit video over the Internet. The parameters obtained after MP, called atoms, are encoded into two balanced descriptions, which are transmitted over two separate channels. Simulation results show that our proposed method surpasses MP single description coding (SDC) and H.263 with FEC as well as MP MDC using shared atoms.
