1. A method comprising:
transmitting, by a first device to a second device, a video stream in a video chain;
receiving, by the first device from the second device, a request for video information, wherein the request includes a plurality of fields associated with a first priority of a first region of interest (ROI) and a second priority of a second ROI, and wherein the request is based on statistical information collected about a plurality of users for the first ROI and statistical information collected about the plurality of users for the second ROI, wherein the plurality of users access the video stream on a set of third devices;
modulating, by the first device, a first quantization step size of the first ROI in the video stream based on the first priority; and
modulating, by the first device, a second quantization step size of the second ROI in the video stream based on the second priority, wherein the first quantization step size is different from the second quantization step size, and wherein the first quantization step size and second quantization step size are different from a third quantization step size of a region of the video stream outside of a ROI.
