1. A process comprising receiving a first representation of a video stream that includes video frames, the representation expressing the video frames at a high pixel resolution, automatically generating a second representation of the video stream that expresses the video frames at a pixel resolution lower than the high pixel resolution, detecting that at least one of the video frames includes a region of interest that is static for a period of time in the video stream, creating a still image of the static region of interest, broadcasting over a broadcast channel to a population of mobile video playing devices the second representation of the video stream that expresses the video frames at the pixel resolution lower than the high pixel resolution, and information, embedded in the video stream having the lower resolution, that represents the region of interest as the still image at a resolution level that is higher than the low pixel resolution.
