1. A method of encoding video data, the method comprising:
- dividing an input picture into a first picture corresponding to a region of interest (ROI) and a second picture corresponding to a non-region of interest (non-ROI);
generating a third picture by down-scaling the second picture;
determining a quantization parameter for the ROI based on the first picture;
determining a quantization parameter for the non-ROI based on the third picture; and
generating a compressed picture by encoding the input picture based on the quantization parameter for the ROI and the quantization parameter for the non-ROI.

Abstract
In a method of encoding video data, an input picture is divided into a first picture corresponding to a region of interest (ROI) and a second picture corresponding to a non-region of interest (non-ROI). A third picture is generated by down-scaling the second picture. A quantization parameter for the ROI is determined based on the first picture. A quantization parameter for the non-ROI is determined based on the third picture. A compressed picture is generated by encoding the input picture based on the quantization parameter for the ROI and the quantization parameter for the non-ROI.

31. A method of encoding video data, the method comprising:
-
dividing an input picture into a plurality of pictures comprising a first picture corresponding to a region of interest (ROI) and a second picture corresponding to a non-region of interest (non-ROI); generating a third picture based on the second picture, the third picture having a bit-depth that is less than a bit-depth of the second picture; and encoding the input picture based on the first picture and the third picture. - View Dependent Claims (32, 36)
