摘要
A method for adaptive quantization of video frames based on bit rate prediction that includes increasing quantization (12) in sectors of a video frame where coding artifacts would be less noticeable to the human visual system and decreasing quantization (14) in sectors where coding artifacts would be more noticeable to the human visual system. In one embodiment the method reverts to uniform quantization (18) for video frames in which adaptive quantization would require extra bits.
