Abstract -
This paper extends the current concept of multiple description coding (MDC) to our proposed domain, by proposing efficient splitting of standard single description coded (SDC) video into a multi-stream representation. The multiple description video splitting (MDVS) scheme is proposed to operate at network edge, which increase robustness in path diversity video streaming across heterogeneous communications chains. Then It shows that poor performance of existing methods is mainly due to distortion accumulation, i.e., drift, when decoding is performed with missing descriptions. The proposed system is able to effectively control drift distortion in both intra and inter expecting coding, even when only one description reaches the decoder. This is performed by generating a controlled amount of relevant side information to compensate for drift accumulation, whenever any data is lost in its path. The analysis result show that any individual description can be decoded on its own without producing drift, getting significant quality improvement at reduced redundancy cost. The total performance evaluation, removed out by simulating video streaming over loss networks with path diversity, and also demonstrates that MDVS enables higher quality video in such heterogeneous networking environments, for a wide range of data loss rates.
