Abstract: An Encoder Assisted Frame Rate Up Conversion (EA-FRUC) system that utilizes video coding and pre-processing operations at the video encoder to exploit the FRUC processing that will occur in the decoder in order to improve compression efficiency and reconstructed video quality is disclosed. One operation of the EA-FRUC system involves determining whether to encode a frame in a sequence of frames of a video content by determining a spatial activity in a frame of the sequence of frames; determining a temporal activity in the frame; determining a spatio-temporal activity in the frame based on the determined spatial activity and the determined temporal activity; determining a level of a redundancy in the source frame based on at least one of the determined spatial activity, the determined temporal activity, and the determined spatio-temporal activity; and, encoding the non-redundant information in the frame if the determined redundancy is within predetermined thresholds.

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 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.

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。
