A system and method for video coding. Energy-concentrating transform operations are performed on video data to obtain transformed data. Nested scalar quantization is performed on the transformed data to generate blocks of coset indices. Bit planes of the blocks of coset indices are encoded using irregular repeat accumulate (IRA) encoders to generate corresponding bit streams. The bit streams are transmitted to a destination device over a channel. A decoder of the destination device receives input data, corresponding to transmitted bit streams, from the channel. The input data is decoded, using side information, to obtain estimates for the blocks of coset indices. Output video data (i.e., an estimate of the original video data) is generated using the estimated blocks of coset indices and the side information.
