Abstract:
1. A method for video encoding, the method comprising: inter-prediction processing of at least one current macroblock of an intra-coded frame in a video sequence; generating temporal statistics based on said inter-predicted at least one current macroblock of said intra-coded frame; generating spatial statistics based on said at least one current macroblock of said intra-coded frame and reference pixels that are from the same frame as said current macroblock; determining a rate control based on said generated temporal statistics and said generated spatial statistics; determining quantization parameters for said at least one current macroblock of said intra-coded frame based on said determined rate control; and intra-prediction encoding said at least one current macroblock that was inter-prediction processed of said intra-coded frame, wherein intra-prediction encoding said at least one current macroblock of said intra-coded frame that was inter-prediction processed further comprises: generating prediction residuals based on said determined quantization parameters and said at least one current macroblock of said intra-coded frame; and encoding said prediction residuals based on said quantization parameters.
