Abstract
Techniques for video with dynamic pixel update rates are described. A first video frame is received from a video source, the first video frame having a first pixel value at a first frame location of a plurality of frame locations, wherein the first frame location includes a horizontal pixel location and a vertical pixel location. A second video frame is received from the video source, the second video frame having a second pixel value at the first frame location. The first frame location is identified based at least in part on determining a difference between the first pixel value and the second pixel value. A package including a pixel update value and an indication of the first frame location is sent to a video destination, wherein the pixel update value is based at least in part on the second pixel value.
