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 playback at the sink devices based on the type of media data received from the source device. If the media data only includes video data and does not include audio data, a processing pipeline of the sink device is configured to render the video data without waiting to synchronize with non-existent audio data. If the media data includes both video data and audio data, an audio rendering start-up timer is reduced and the processing pipeline renders synchronized audio and video data according to the reduced start-up timer.
摘要翻译：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，这些技术包括基于从源设备接收的媒体数据的类型在宿设备处定制回放。如果媒体数据仅包括视频数据并且不包括音频数据，则宿设备的处理流水线被配置为呈现视频数据而不等待与不存在的音频数据同步。如果媒体数据包括视频数据和音频数据，则减少音频再现启动定时器，并且处理流水线根据减少的启动定时器呈现同步的音频和视频数据。
