Abstract: A first representation of a video stream is received that includes video frames, the representation expressing the video frames at a relatively high pixel resolution. At least one of the video frames is detected to include a region of interest. A second representation of the video stream that expresses the video frames at a relatively low pixel resolution is provided to a video playing device. Included with the second representation is additional information that represents at least a portion of the region of interest at a resolution level that is higher than the relatively low pixel resolution.
