Abstract
A method for video stream processing in a video chain is provided that includes transmitting a video stream in the video chain, receiving, by a first video node in the video chain, a region of interest (ROI) command from a second video node in the video chain, wherein the ROI command includes an ROI type indicator, and performing, by the first video node, the ROI command according to the ROI type indicator.
Claims18
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 region of interest (ROI) request, wherein the ROI request comprises a first ROI type indicator that indicates a type of a first ROI, a second ROI type indicator that indicates a type of a second ROI, a first ROI priority field that indicates a first priority of the first ROI, and a second ROI priority field that indicates a second priority of the second ROI, wherein the first ROI priority field indicates a higher priority than the second ROI priority field, wherein the type of the first ROI is different than the type of the second ROI, and wherein the first ROI request is based on statistical information collected about a set of third devices;
- modulating, by the first device, a quantization step size of the first ROI in the video stream based on the first ROI type indicator and the first ROI priority field;
- and
- modulating, by the first device, a quantization step size of the second ROI in the video stream based on with the second ROI type indicator and the second ROI priority field.

A system comprising:
- a first device;
- and
- a second device communicatively coupled to the first device;
- and
- wherein the first device comprises:
- at least one first processor;
- and
- a first non-transitory computer readable storage medium storing a first program for execution by the at least one first processor, the first program including first instructions to:
- transmit a video stream to the second device;
- receive a region of interest (ROI) inquiry from the second device, wherein the ROI inquiry comprises a first ROI type indicator that indicates a first ROI type and a second ROI type indicator that indicates a second ROI type, wherein the first ROI type is different than the second ROI type, and wherein the first ROI inquiry is based on statistical information collected about a set of third devices;
- identify a first ROI of the first ROI type in the video stream;
- identify a second ROI of the second ROI type in the video stream;
- and
- modulate a quantization step size of the first ROI in the video stream based on the first ROI type indicator and the first ROI priority field;
- and
- modulate a quantization step size of the second ROI in the video stream based on with the second ROI type indicator and the second ROI priority field.

A first device, comprising:
- at least one processor;
- and
- a non-transitory computer readable storage medium storing a program for execution by the at least one processor, the program including instructions to:

- receive, from the second device, a region of interest (ROI) inquiry, wherein the ROI comprises a first ROI type indicator that indicates a first ROI type and a second ROI type indicator that indicates a second ROI type, wherein the first ROI type is different than the second ROI type, and wherein the ROI inquiry is based on statistical information collected about a set of third devices;
- identify a first ROI of the first ROI type in the video stream;
- identify a second ROI of the second ROI type in the video stream;
- and
- modulate a quantization step size of the first ROI in the video stream based on the first ROI type indicator and the first ROI priority field;
- and
- modulate a quantization step size of the second ROI in the video stream based on with the second ROI type indicator and the second ROI priority field.
