摘要： A sink device in a Wireless Display (WD) system may send performance information feedback to a source device to adjust media data processing at the source device. The performance information feedback may include performance indicators of the WD system that are capable of being measured or calculated at the sink device based on received media data or request to adjust the transmission of media data. For example, the performance information feedback may include one or more of round trip delay, delay jitter, packet loss ratio, error distribution, and received signal strength indication (RSSI). The feedback channel may be piggybacked on a reverse channel architecture referred to as the User Input Back Channel (UIBC) implemented between the source device and the sink device.

摘要： This disclosure describes techniques that can improve the generation of a decomposed multi-stream (DMS) by a host device of a video display system and the display of a DMS by a client device of the video display system. The techniques may apply different frame rates to different streams within a DMS, and the frame rates may depend on the content. For example, one stream within a DMS may comprise a sequence of full-motion video information, which may be rendered at a relatively high frame rate. However, another stream within the DMS may be associated with a background of the display, various graphic user interface control windows or elements, or a display window that includes non-video content (such as e-mail or a document). The second stream in the DMS may be rendered at a much slower frame rate than that used for the sequence of full-motion video information.
摘要翻译： 本公开描述了可以通过视频显示系统的主机设备改进生成分解的多流（DMS）的技术，以及由视频显示系统的客户端设备显示DMS。 这些技术可以对DMS内的不同流应用不同的帧速率，并且帧速率可以取决于内容。 例如，DMS内的一个流可以包括可以以相对高的帧速率呈现的全运动视频信息的序列。 然而，DMS内的另一个流可以与显示器的背景，各种图形用户界面控制窗口或元件或包括非视频内容（诸如电子邮件或文档）的显示窗口相关联。 DMS中的第二个流可以以比用于全动态视频信息序列的帧速率慢得多的帧速率来渲染。

摘要： This disclosure relates to techniques to establish a multicast communication session between a source device and multiple sink devices in a Wireless Display (WD) system. Two or more sink devices may be interested in receiving the same media data from the source device. According to the techniques, the source device establishes a multicast session with the sink devices in the WD system, and sends a single copy of multicast media data for the multicast session to the interested sink devices using a receiving multicast port. The source device selects a receiving multicast port number as a destination identifier for each multicast session. The sink devices interested in receiving the media data of a given multicast session bind on the receiving multicast port for the multicast session. This disclosure describes several exemplary multicast subscription procedures to ensure correct binding on the receiving multicast port at each of the sink devices.
