    摘要: As part of a communication session, a wireless source device can transmit audio and video data to a wireless sink device, and the wireless sink device can transmit user inputs received at the wireless sink device back to the wireless source device. In this manner, a user of the wireless sink device can control the wireless source device and control the content that is being transmitted from the wireless source device to the wireless sink device. As part of transmitting user input to the source device, the sink device can generate a data packet with a data packet header that includes a timestamp flag indicating the presence of a timestamp field, and the source device can process the data packet based on a timestamp in the timestamp field.

    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.
