Abstract
A video signal processor is provided, having an inverse quantizer, an inverse transform processor, an in-loop filter; and a decoded picture buffer. The video signal processor is configured to receive a video signal including a picture comprising quantized pixels, wherein the picture includes a first region and a second region. The first region comprising a first plurality of blocks and having a first quantization parameter based on a first average measure of spatial activity information of the first plurality of blocks; and a second region comprising a second plurality of blocks and having a second quantization parameter based on a second average measure of information of the second plurality of blocks. The inverse quantizer being configured to inverse quantize the pixels of the blocks comprising the first region using the first quantization parameter and inverse quantize the pixels of the blocks comprising the second region using the second quantization parameter.
