    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.

    Abstract: This disclosure provides systems, methods, and apparatuses for providing multi-view (MV) video data via a wireless network. For example, the apparatus may include a processor configured to determine at least a first channel quality estimate of a communication channel of the wireless network used to transmit first MV video data. The apparatus may include an input/output (I/O) controller configured to receive a binocular disparity error estimate indicative of a rendering of the first MV video data. The processor may be configured to determine whether to continue to at least one of capture, encode, and/or transmit MV video data based at least in part on the first channel quality estimate and/or the binocular disparity error estimate.

    Abstract: Techniques are described for tunneling high definition multimedia interface (HDMI) data over a wireless connection from an HDMI-capable source device to a client device that is physically connected to an HDMI-capable sink device via an HDMI connector. The techniques enable wireless transmission of HDMI data without video compression by using an encapsulation scheme that maps HDMI audio and video channels into a transport stream format and maps HDMI side channels into an IP datagram for transmission over the wireless connection. The source device may operate as an HDMI controller and perform HDMI-based data, control, and security processing required for HDMI connectivity with the sink device via the client device. The client device, therefore, may be a “dummy” client device that does not perform HDMI-based processing, but acts as a wireless HDMI bridge to pass the HDMI data between the source device and the sink device.

    Abstract translation: 描述了通过无线连接将HDMI高清晰度多媒体接口（HDMI）数据从支持HDMI的源设备隧道传送到通过HDMI连接器物理连接到具有HDMI能力的宿设备的客户端设备的技术。 这些技术通过使用将HDMI音频和视频信道映射成传输流格式并将HDMI侧信道映射到IP数据报中以通过无线连接进行传输的封装方案，实现HDMI数据的无线传输而无需视频压缩。 源设备可以作为HDMI控制器操作，并且经由客户端设备执行与宿设备的HDMI连接所需的基于HDMI的数据，控制和安全处理。 因此，客户端设备可以是不执行基于HDMI的处理的“虚拟”客户端设备，而是用作无线HDMI桥接器以在源设备和宿设备之间传递HDMI数据。

    Abstract: 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.

    Abstract: Methods, systems, apparatuses, and devices are described for reverse channel audio (RCA) session establishment and management. A sink device may identify a unidirectional communication channel with a source device. The sink device may determine that a trigger is present, where the trigger is associated with a RCA transmission to the source device, and establish a RCA session for transmitting the RCA transmission to the source device based at least in part on the identified trigger. A source device may identify a unidirectional communication channel with a sink device and receive an indication that a sink device supports RCA transmissions, such as via the unidirectional communication channel. The source device may transmit a trigger to the sink device to initiate the RCA transmission, such as via the unidirectional communication channel, and receive the RCA transmission from the sink device based at least in part on the trigger.
