This report presents a layer-optimized streaming technique for delivering video content over the Internet using quality-scalable motion-compensated orthogonal video. We use Motion-Compensated Orthogonal Transforms (MCOT) to remove temporal and spatial redundancy. The resulting subbands are quantized and entropy coded by Embedded Block Coding with Optimized Truncations (EBCOT). Therefore, we are able to encode the input video into multiple quality layers with sequential decoding dependency. A layer-distortion model is constructed to measure the trade-off between expected streaming layer and expected distortion. Due to the sequential dependency among streaming layers, we build a cost function with concave properties. With that, we develop a fast algorithm to find the optimal trans-mission policy at low computational complexity. The experiments demonstrate the advantages of expected distortion and computational complexity for challenging streaming scenarios.
