  • Direct streaming for wireless display
    Patent number: 9665336
    Abstract: 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.
    Type: Grant
    Filed: December 22, 2014
    Date of Patent: May 30, 2017
    Assignee: QUALCOMM Incorporated
    Inventors: Sanal Kumar Karunakaran, Sanjay Kumar Agrawal, Sateesh Naidu Gorrepati, Devraj Gajraj Gupta
  • Streaming control for real-time transport protocol
    Patent number: 9648073
    Abstract: 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.
