N2 - The main hindrance to the development of efficient low-latency multiple description (MD) video coders are the problem of predictive mismatch. In this paper, we present a two-channel predictive MD video codec architecture based on the recently proposed WYZE-PMD framework. The proposed codec transmits coset information to curtail error-propagation caused by predictive mismatch, without requiring high latency or restrictive channel assumptions. MD scalar quantizers are used to generate multiple descriptions, low-density parity check (LDPC) codes are used to generate coset information, and the H.263 video coding standard is used for efficient motion compensation. The proposed codec is used to code descriptions of CIF video for communication over two erasure channels with independent failure probabilities. Results indicate that the proposed codec provides efficient, drift-free predictive MD coding.
