A client device for use in processing reality technology content is provided. The client device comprises memory configured to store data and a processor in communication with the memory. The processor is configured to receive, from a server device via network communication channel, a video stream comprising encoded video frames and motion vector information and extract, at the client device, the motion vector information. The processor is also configured to decode the video frames, determine whether to at least one of time warp the video frames and space warp the video frames using the extracted motion vector information. The processor is also configured to display the warped video frame data.

Frame reprojection for virtual reality and augmented reality

A method and apparatus for reducing latency in a virtual reality system including a plurality of devices comprises capturing and transmitting, by a first device, a first batch of data to a second device. The second device renders and encodes a second data based upon the first batch of data, and transmits the first encoded image to the first device. Based upon a determination of a likelihood of collision between a transmission of a second batch of data from the first device and the transmission of the second data, the first device adjusts a frequency of capturing and transmitting the second batch of data.

Method and apparatus for reducing latency and collisions in a virtual reality/alternate reality system

Systems, apparatuses, and methods for reducing latency for wireless virtual and augmented reality applications are disclosed. A virtual reality (VR) or augmented reality (AR) system includes a transmitter rendering, encoding, and sending video frames to a receiver coupled to a head-mounted display (HMD). In one scenario, rather than waiting until the entire frame is encoded before sending the frame to the receiver, the transmitter sends an encoded left-eye portion to the receiver while the right-eye portion is being encoded. In another scenario, the frame is partitioned into a plurality of slices, and each slice is encoded and then sent to the receiver while the next slice is being encoded. In a further scenario, each slice is being encoded while the next slice is being rendered. In a still further scenario, each slice is prepared for presentation by the receiver while the next slice is being decoded by the receiver.

Reducing latency in wireless virtual and augmented reality systems

A method and system for producing a single view video signal based on a multiview video coding (MVC) signal stream. A MVC signal stream representing multiple spatially related views of a scene, including a base view and at least one dependent view, is decoded to provide multiple decoded video signals representing the spatially related views, with respective portions of the MVC signal stream representing one of multiple temporally adjacent video frames, and the MVC signal stream representing multiple sequences of spatially adjacent video frames. The decoded video signals are processed to provide a processed video signal representing one of the spatially related views using image information from more than one of the decoded video signals. As a result, more image data is used during processing, thereby improving the spatial and temporal image quality.
