Abstract: Various embodiments include methods, systems, and devices for streaming a compressed media stream between a source computing device and a sink computing device. In some embodiments, the source computing device and the sink computing device may be operating in Wi-Fi Miracast® direct mode. Various embodiments may enable a sink computing device to indicate a pre-transmitted data maximum buffer size and/or an indication of an access unit drop capability to a source computing device. Various embodiments may provide a priority-based transmission scheme for use by a source computing device sending access unit meta data of a compressed media stream, such as presentation time stamps, render statuses, etc., to a sink computing device. Various embodiments may enable a sink computing device to drop access units that were dropped by a source computing device.

Abstract: A source device may transmit video frames of a video stream over a communication link to a sink device, where each video frame corresponds to a presentation timestamp (PTS) frame comprising a frame capture time and a frame transmit start time associated with the corresponding video frame. The sink device may determine a latency metric for the video frame based at least in part on the PTS frame and a size of the video frame and generate frame latency statistics comprising frame latency information categorized by frame size into one or more categories. The source device may receive the frame latency statistics from the sink device. The source device may adjust at least one media processing parameter for the video stream based at least in part on the frame latency statistics.

Abstract: Systems, methods, and devices enabling scalability to be incorporated into a media presentation such that the media presentation at a client end may be continuous or at least substantially continuous in the presence of missing segment files. In an embodiment, the loss of one or more segment file may not require a media presentation interval associated with the missing segment file to be skipped at the client end. Systems, methods, and devices enable scalability in live streaming and/or on-demand presentations.

Abstract: Systems, methods, and devices of the various embodiments enable HTTP streaming that downloads different layers of the same media interval at different points of time before the play out time of that media interval. The various embodiments provide a download sequence that enables downloads of portions of a media interval to continue at different points in time until the play out position of the media presentation reaches a certain point with respect to the media interval. In an embodiment, the download sequence may rapidly adapt to changing network bandwidth conditions and may help ensure no stall occurs in media play out under minimum conditions. In an embodiment, the download sequence may provide an increased smoothing effect to reduce the rate of adaptation to changes in bandwidth, which may reduce the fluctuations in quality in the presence of repeated abrupt network changes.
