A source device comprises a memory to store video data and one or more processors, wherein the one or more processors are configured to obtain encoded video data for a frame of video data; output, via a display interface for the source device and for display at a display device, a predefined frame for the frame of video data; and send, to a sink device via a wireless communication channel, the encoded video data for display at a display device associated with the sink device.

Direct streaming for wireless display

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.

Streaming control for real-time transport protocol

In one example, a method includes, during operation of a wireless media share session between a primary source device and a sink device, transferring, from the primary source device to a secondary source device using a wireless link, transmission rights to the media share session with the sink device.
