Abstract: A device and method for processing Virtual Reality (VR) data is disclosed. The method comprises transmitting feedback information from the device to a server, wherein the feedback information is captured in the device, receiving data from the server to be presented on the device based on the feedback information, wherein the data includes video data and audio data where the video data is a frame of video data in a sequence of frames and the audio data is the corresponding audio data of the frame, decoding the video data and corresponding audio data of the frame, and controlling the presentation of the video data and corresponding audio data on the device such that the video data is synchronized with the corresponding audio data.

Abstract: Virtual Reality (VR) processing devices and methods are provided for transmitting user feedback information comprising at least one of user position information and user orientation information, receiving encoded audio-video (AN) data, which is generated based on the transmitted user feedback information, separating the A/V data into video data and audio data corresponding to a portion of a next frame of a sequence of frames of the video data to be displayed, decoding the portion of a next frame of the video data and the corresponding audio data, providing the audio data for aural presentation and controlling the portion of the next frame of the video data to be displayed in synchronization with the corresponding audio data.

Abstract: A method and system for directing image rendering, implemented in a computer system including a plurality of processors includes determining one or more processors in the system on which to execute one or more commands. A graphics processing unit (GPU) control application program interface (API) determines one or more processors in the system on which to execute one or more commands. A signal is transmitted to each of the one or more processors indicating which of the one or more commands are to be executed by that processor. The one or more processors execute their respective command. A request is transmitted to each of the one or more processors to transfer information to one another once processing is complete, and an image is rendered based upon the processed information by at least one processor and the received transferred information from at least another processor.

Abstract: Virtual Reality (VR) systems, apparatuses and methods of processing data are provided which include predicting, at a server, a user viewpoint of a next frame of video data based on received user feedback information sensed at a client, rendering a portion of the next frame using the prediction, encoding the portion, formatting the encoded portion into packets and transmitting the video data. At a client, the encoded and packetized A/V data is received and depacketized. The portion of video data and corresponding audio data is decoded and controlled to be displayed and aurally provided in synchronization. Latency may be minimized by utilizing handshaking between hardware components and/or software components such as a 3D server engine, one or more client processors, one or more client processors, a video encoder, a server NIC, a video decoder, a client NIC; and a 3D client engine.

Abstract: Described is a method and system to efficiently compress and stream texture-space rendered content that enables low latency wireless virtual reality applications. In particular, camera motion, object motion/deformation, and shading information are decoupled and each type of information is then compressed as needed and streamed separately, while taking into account its tolerance to delays.
