Distortion analyses for temporal scalability coding techniques

A temporally scalable video coding algorithm allows extraction of video of multiple frame rates from a single coded stream. This paper compares the rate-distortion performance of three temporally scalable coding techniques: temporal subband coding (TSB), motion-compensated temporal subband coding (MC-TSB), and motion compensated prediction (MCP). The distortions are derived in terms of various temporal pixel correlations and the probability of occlusion. Measured values are used to predict performances at full and lower frame rates, and a comparison with experimental quantitative performances demonstrates that the performance ranking is correctly predicted and bounds the accuracy of the analyses at high rates. MCP and MC-TSB always outperform TSB. For high bit rate full-frame-rate video, MCP and MC-TSB perform equivalently. At lower frame rates, MCP provides better performance
