Method and system for using motion prediction to equalize video quality across intra-coded frames

摘要

In a video processing system, a method and system for using motion estimation to equalize video quality across intra frames are provided. Inter-prediction processing may be enabled for macroblocks in an “I” frame to generate temporal statistics. The inter-prediction processing may comprise motion estimation and motion compensation. Spatial statistics may be generated from the macroblocks in the “I” frame. A rate control may be determined based on the inter-prediction processing and spatial statistics.

1. A method for encoding a video sequence, the method comprising:
selecting a frame of a group of pictures (GOP) that has been designated as an intra-coded frame; inter-prediction processing of at least one current macroblock of the intra-coded frame; generating spatial statistics of the at least one current macroblock of the intra-coded frame; determining a rate control for video encoding based on temporal statistics from the inter-prediction processing and the spatial statistics of the at least one current macroblock of the intra-coded frame; and allocating a number of bits to the intra-coded frame from a total number of bits allocated to the GOP based on the determined rate control.
