    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.

  • Patent number: 10129839
    Abstract: Methods, systems, apparatuses, and devices are described for synchronizing timing of wireless streaming transmissions to multiple sink devices. A source device may identify timing information associated with a common timing source, e.g., a media timing source at Multimedia layer or a Wi-Fi timing source, and send the timing information to the sink devices. The sink devices may receive the timing information and determine a composite timing delay, e.g., a wireless transmission link delay, an internal interface link delay, or combinations thereof. The source device may stream the content to the sink devices which may use a locally adjusted timing signal to synchronize the presentation of the content.

  • Patent number: 9939869
    Abstract: The various aspects provide methods, systems, and devices for coordinating the operating states of multiple SOCs within a computing device. Such coordination may be implemented through communication of information by the SOCs that represent advance notice of impending interactions between each other. The communicated information may be used by a recipient SOC for setting its operating state in advance of the potential impending interaction with another SOC. Accordingly, this technical improvement enables individual SOCs to preemptively influence the operating states of the other SOCs. For example, in the context of power management, the various aspects may coordinate the power states of multiple SOCs, thereby effectively implementing a monolithic power management state machine that improves overall power consumption of the computing device.

  • Patent number: 9749682
    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.

  • Patent number: 9668204
    Abstract: The disclosure relates to a collaborative demand-based dual-mode Wi-Fi network control framework that may optimize wireless power and performance on wireless devices that may support multiple Wi-Fi networking technologies. In particular, a high performance Wi-Fi link may be reserved to services or applications that have substantial quality of service (QoS) requirements and conventional Wi-Fi links may be utilized to transfer data for services or applications that have typical performance requirements. For example, bandwidth requirements associated with forward traffic may be measured according to sizes and latency requirements associated with the forward traffic and the appropriate Wi-Fi networking mode may be controlled according to the forward traffic bandwidth requirements in combination with the average bandwidth and average retransmission rate associated with the conventional Wi-Fi links, among other factors.

  • 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.
