Method of increasing coding efficiency and reducing power consumption by on-line scene change detection while encoding inter-frame

摘要: A system and method for on-the-fly detection of scene changes within a video stream through statistical analysis portion the macroblocks comprising each frame as they are processed using inter-frame coding. If selected current differs from previous by exceeding predetermined thresholds, is assumed to be change. Once change detected, remainder encoded an intra-frame, intra-macroblocks, or intra slices, implementation one more adaptively adjusted quantization parameters reduce computational complexity, decrease power consumption, increase resulting image quality. As decoding inverse encoding, these improvements similarly recognized decoder it decodes stream.
