Abstract: A method, an apparatus, and a computer program product provide feedback to a user of an augmented reality (AR) device having an optical see-through head mounted display (HMD). The apparatus obtains a location on the HMD corresponding to a user interaction with an object displayed on the HMD. The object may be an icon on the HMD and the user interaction may be an attempt by the user to select the icon through an eye gaze or gesture. The apparatus determines whether a spatial relationship between the location of user interaction and the object satisfies a criterion, and outputs a sensory indication, e.g., visual display, sound, vibration, when the criterion is satisfied. The apparatus may be configured to output a sensory indication when user interaction is successful, e.g., the icon was selected. Alternatively, the apparatus may be configured to output a sensory indication when the user interaction fails.

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.

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.

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.

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.

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.

The second key is transmitted via a unicast protocol and is encrypted is based upon a point-to-point security framework (e.g., IPSec). The media presentation device(s) each decrypt the first key using the second key, and then decrypt the media using the decrypted first key. The media presentation device(s) then present at least a portion of the decrypted media.

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.
