摘要： 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.

摘要： 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.

摘要： Adaptive decoder-drive encoder reconfiguration techniques are described. In one example, techniques include detecting an operational condition at a consumer using a sensor, the consumer receiving a communication of digital content from an encoder; generating an adaptation instruction by the decoder based on the detecting; transmitting the adaptation instruction by the decoder for receipt by the encoder; and receiving an adapted communication of the digital content generated by the encoder, the adapted communication caused by reconfiguration of the encoder based on the adaptation instruction received from the decoder.

摘要： 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.
