在这项工作中，我们提出了一种基于分布式源编码原理的新的视频编码范式PRISM （Power-efficient Robust high-compression Syndrome-based Multimedia coding）。PRISM具有帧内（静止图像）视频编码的低编码复杂度，接近全运动帧间视频编码的高压缩效率，同时与传统视频编码架构（MPEG和H.26L）相比，对漂移问题和信道损失具有天然的鲁棒性。这些特点使其非常适合上行链路丰富的应用，如无线网络多媒体、无线视频和传感器摄像机等。
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.
