抜粋

Multiple description coding (MDC) is one of source coding techniques to encode realtime application source into multiple bitstreams. MDC supports multiple quality levels of decoding when transmitted over lossy channels such as packet networks. An MDC source encoder provides different representations of the source such that; when all descriptions are available at the receiver, an high-quality reconstruction of the source is possible, while if only a small number of descriptions is available, a reconstruction is still possible even though a lower quality, but acceptable is obtained. Therefore, this coding technique is expected to apply applications which prefer accepting error of data to retransmitting the lost or erroneous data over multipath noisy network. Multiple Description Correlating Transforms coding (MDCTC) is a method to realize MDC with a matrix. Based on this method, this paper proposes the three ratio configuration method for Multiple Description Correlating Transforms coding (RMDCTC), which can control the volume ratio of descriptions to source data. Therefore, RMDCTC can adjust the data size ratio among descriptions to fit the ratio of channel bandwidths and is suitable to apply error allowable communicating applications over asymmetric multipath noisy network. In addition, each three ratio configuration method has different feature. Therefore, it is possible to select suitable method as the situation demands. As a result, the proposed methods are more practical method than traditional MDCTC.
