摘要： 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 customized buffering at the sink devices based on application awareness for the media data. The techniques include learning the type of application for the media data, and adjusting the size of buffers in the processing pipeline to achieve an appropriate balance between smoothness and latency for the application type. For example, when the media data is for a video playback application, the techniques include increasing the buffer size to increase smoothness in the video playback application.

摘要： 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.
