Abstract
This paper proposes a SNR scalability method based on the H.264/AVC video coding standard. The method partitions the compressed video data into layers with different quantization precisions. The base layer contains more important parts of the video data while the enhancement layer delivers the additional data to improve the video SNR quality. Therefore, it can be considered as an alternative method to the data partitioning technique that is already supported by the standard. By applying better error protection methods to the base layer, the delivered video is guaranteed to meet a minimum quality when transmitted over error prone environments. Simulation results show that the bitstreams generated by our layering method have better quality when transmitted in high erroneous channels compared to data partitioning.
