SYSTEM AND METHOD FOR PROVIDING IMPROVED RESIDUAL PREDICTION FOR SPATIAL SCALABILITY IN VIDEO CODING

摘要

: A system and method for providing improved residual prediction for spatial scalability in video coding. In order to prevent visual artifacts in residual prediction in extended spatial scalability (ESS), each enhancement layer macroblock is checked to determine if the macroblock satisfies a number of conditions. If the conditions are met for an enhancement layer macroblock, then it is likely that visual artifacts will be introduced if applying residual prediction on the macroblock. Once such locations are identified, various mechanisms may be used to avoid or remove the visual artifacts. No. of Pages : 37 No. of Claims : 19
