Abstract :
In this work, we present PRISM (Power-efficient Robust high-compression Syndrome-based Multimedia coding), a new video coding paradigm based on the principles of distributed source coding. Incurring the low encoding complexity of intra-frame (still-image) video coding, PRISM approaches the high compression efficiency of full-motion inter-frame video coding, while simultaneously offering natural robustness to the drift problem and channel loss in direct contrast to conventional video coding architectures (MPEG and H.26L). These traits make it well-matched to uplink-rich applications such as multimedia over wireless networks, wireless video and sensor cameras, etc.
