Abstract: This disclosure describes techniques to improve a user experience in a Wireless Display (WD) system. The WD system includes a source device that provides media data to one or more sink devices. The techniques are directed toward reducing end-to-end latency in the WD system while improving video playback quality at the sink devices. More specifically, the techniques include low latency screen capture and buffering at the source device. For example, a processing pipeline of the source device may be configured to include minimum-size buffers between processing steps to reduce latency. The techniques include buffering a most recent frame update captured from the media data in the minimum-size buffers and dropping older frame updates when the minimum-size buffers are full. In addition, the processing pipeline may be configured to use hardware acceleration to retrieve the frame updates from the buffers for processing.
Abstract translation: 本公开描述了在无线显示（WD）系统中改善用户体验的技术。 WD系统包括向一个或多个宿设备提供媒体数据的源设备。 这些技术旨在减少WD系统中的端到端延迟，同时提高信宿设备的视频播放质量。 更具体地，这些技术包括在源设备处的低延迟屏幕捕获和缓冲。 例如，源设备的处理流水线可以被配置为在处理步骤之间包括最小大小的缓冲器以减少等待时间。 这些技术包括缓冲从最小尺寸缓冲器中的媒体数据捕获的最新帧更新，并在最小大小缓冲区已满时丢弃较旧的帧更新。 此外，处理管线可以被配置为使用硬件加速来从缓冲器检索帧更新以进行处理。

Abstract: Aspects of the present disclosure provide improved image resizing techniques including seam craving and seam lining that consider image content in addition to geometric constraints. In one aspect of the disclosure, the energy for each of the pixels of an image is determined in accordance with an energy function. A line energy is determined for each straight line of the image, and the line energy corresponds to a sum of the energy of the pixels in each straight line. A plurality of starting points are identified for a plurality of seams corresponding to the straight lines having the lowest line energy. Further, the paths for each of the seams are determined. The image may be resized by removing the seams from the image.

Abstract: Aspects of the present disclosure provide for efficient streaming of video sequences in such a way that multiple receiving devices can simultaneously display the video sequence at their full resolution. For example, some aspects of the disclosure combine seam carving, for retargeting a video sequence, with multiple description coding, for transmission of two or more streams corresponding to descriptions of the video sequence. At the receiving end, the descriptions can be aggregated and decoded, and optionally, resized to full HD resolution utilizing seam lining.
