Multiple-description coding (MDC) is a source coding technique which provides an effective way to mitigate the effects of packet errors/loses by making use of multiple channels. The most attractive application of MDC is perhaps the multiple-description video coding (MDVC) in the peer-to-peer (P2P) scenario so as to support simultaneous video streaming to a large population of clients. To this end,...
Multiple-description coding (MDC) encodes a source image or video into several distinct descriptions. Each description can be decoded independently and more than one description can also be decoded jointly so as to deliver a higher quality. One typical design of an MDC encoder is based on the so-called multiple description scalar quantization (MDSQ). A simple MDSQ system is to choose different step-sizes...
