Abstract
A system (and a method) are disclosed for reducing intra frame beating effect at frame level and macroblock (MB) level within a video processing system. The frame-level system includes a pre-encoding unit, a reconstruction unit, an intra-beat frame evaluation unit, an intra-beat frame selection unit and an entropy encoding unit. The pre-encoding unit identifies an intra-beat frame of current group of pictures (GOP) and its corresponding intra-beat reference frame, and predicts the intra-beat frame by its intra-beat reference frame. The intra-beat frame evaluation unit calculates an intra-beat frame score. The intra-beat frame selection unit selects an intra-beat frame for re-encoding. The macroblock-level system includes corresponding processing units as frame-level system, but configured to efficiently process MBs. The macroblock-level system allows each MB of an intra-beat frame to be selectively pre-filtered using its intra-beat reference frame.
