Abstract

We address the problem of robust low-delay video multicast over wireless networks and propose an MPEG/H.26x compatible receiver-driven multicast system. Distributed source coded (DSC) data and forward error correction (FEC) coded parity data are sent to different multicast groups. Heterogeneous receivers with different bandwidth and channel conditions can dynamically switch between subscribing to FEC multicast group(s) and DSC multicast group(s) to enhance the quality of decoded video based on their individual decoding status. Simulations show that this approach has advantages over pure-FEC based schemes and random intra-refresh, especially when the delay constraint is stringent and the transmission channel loss has a bursty nature, as is true in wireless channels.
