Abstract: Systems and methods for bandwidth-limited video transport are configured to receive (or otherwise discern) a selection of video parameter limits that correspond to a bandwidth limit and apply the video parameter limits to an input video stream to enforce the bandwidth limit while preserving video quality. Methods may include adjusting the video stream one parameter at a time until the adjusted video stream meets the bandwidth limit. Parameters to be adjusted may include image resolution, frame rate, image compression, color depth, bits per pixel, and/or color encoding. In some embodiments, the image resolution is reduced first, the frame rate is reduced next, and the image compression is increased last. The extent and/or order of the adjustments of the parameters may be selected by the user, based on the content of the video stream, and/or based on the bandwidth limit.
