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 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.
摘要翻译：本公开涉及在无线显示（WD）系统中在源设备和多个宿设备之间建立组播通信会话的技术。两个或多个宿设备可能感兴趣从源设备接收相同的媒体数据。根据这些技术，源设备与WD系统中的宿设备建立组播会话，并使用接收组播端口将多播会话的组播媒体数据的单一副本发送给感兴趣的宿设备。源设备选择接收多播端口号作为每个多播会话的目的地标识符。对接收给定组播会话的媒体数据有兴趣的接收设备在组播会话的接收组播端口上进行绑定。本公开描述了几种示例性多播订购过程，以确保在每个宿设备处的接收多播端口上的正确绑定。

摘要： In one example, this disclosure describes a method that includes, in an example, determining, by a source device, that display data rendered by the source device comprises one or more displayable graphical objects. The method also includes in response to determining an event, selecting, by the source device, a set of the one or more graphical objects for rendering at a sink device. The method also includes generating, by the source device, configuration data based at least in part on the set of the one or more graphical objects, wherein the configuration data is usable by the sink device to render representations of graphical objects in the set of one or more graphical objects based at least in part on one or more display parameters associated with the sink device. The method also includes sending, by the source device, the configuration data to the sink device.

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.
