摘要： 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.

摘要： Systems and methods of the present disclosure provide for dynamic delay equalization of related media signals in a media transport system. Methods include receiving a plurality of related media signals, transporting the related media signals along different media paths, calculating uncorrected propagation delays for the media paths, and delaying each of the related media signals by an amount related to the difference between the longest propagation delay (of the uncorrected propagation delays) and the uncorrected propagation delay of the related media signal/media path. Calculating the uncorrected propagation delays and delaying the related media signals may be performed in response to a change to the propagation delay of at least one of the related media signals/media paths. Additionally or alternatively, calculating the uncorrected propagation delays and delaying the related media signals may be performed while transporting the related media signals.
