    • 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.
    • 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。
