摘要： Methods, systems, and devices are described for service discovery and session establishment framework to enable a synchronous audio/video streaming service from a source to multiple sink devices. In accordance with the present disclosure, a plurality of sink devices (e.g., Wi-Fi speakers) may be deployed in a flexible (e.g., plug-and-play) fashion and may be discoverable by the source device. In some examples, the devices from multiple vendors may interoperate and easily connect with the source device for flexible configuration based on the media content or number of available sink devices. Thus, the present disclosure provides a method for service specific discovery associated with synchronous audio/video streaming by utilizing Application Service Platform (ASP) service discovery prior to establishment of a display service session from a source device to multiple sink devices.

摘要： The disclosure relates to a low-power co-processor subsystem that can optimize power consumption in a wireless service platform having a main wireless application datapath, wherein the low-power co-processor subsystem may offload certain service discovery tasks from the main wireless application datapath (e.g., such that components residing therein can transition to a low-power state). For example, the service discovery tasks offloaded to the low-power co-processor subsystem may be determined according to protocol-specific service descriptions associated with one or more services to be provided and/or consumed at a wireless device. Furthermore, rules to wake the components in the main wireless application datapath may be dynamically defined and redefined or otherwise tuned to maximize the time that the components in the main wireless application datapath can spend in the low-power state and to determine conditions under which to selectively wake the components in the main wireless application datapath as needed.

摘要： Methods, devices, systems, and non-transitory process-readable storage media for scalable data service distribution in a wireless network. A processor of a source computing device in a wireless network, such as a WiFi Miracast® network, may group all sink computing devices scheduled to receive a frame or packet of a service into a single multicast group and transmit a multicast frame or packet to the sink computing devices. Individual sink computing devices in the network may be configured to send error logs indicating the quality of their respective wireless connections with a source computing device to the source computing device. Operations of estimating a channel state, determining whether the estimated channel state satisfies an error threshold value, and generating an error log may be performed in one or more hardware modules of sink computing devices.

摘要： Dynamic control of transport protocols utilized in the streaming of media content based in part on the type of content, latency requirements, network conditions and/or device capabilities is described. The techniques provide a source device to dynamically switch between User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) to stream media content to a sink device. For example, during a Wi-Fi peer-to-peer remote display session associated with real-time media content (e.g., live streaming sporting event, or gaming applications), the source device may utilize Real-time Transport Protocol (RTP) over UDP to transmit the media stream to the sink device. Conversely, when the media content is not latency critical, such as playback of stored media (e.g., movie), the source device may dynamically switch to RTP over TCP in order to provide reliable data transmission.
摘要翻译：描述了部分基于内容类型，延迟要求，网络条件和/或设备能力的媒体内容流媒体中使用的传输协议的动态控制。这些技术提供了一种源设备，用于在用户数据报协议（UDP）和传输控制协议（TCP）之间动态切换流媒体内容到宿设备。例如，在与实时媒体内容（例如，直播流体育赛事或游戏应用程序）相关联的Wi-Fi点对点远程显示会话期间，源设备可以利用实时传输协议（RTP） UDP将媒体流传输到宿设备。相反，当媒体内容不是延迟至关重要时，例如播放存储的媒体（例如，电影）时，源设备可以动态地切换到TCP上的RTP，以便提供可靠的数据传输。
