Abstract: Embodiments of the present disclosure support a head-mounted display (HMD) wirelessly coupled to a console. The HMD includes a positional tracking system, a beam controller and a transceiver. The positional tracking system tracks position of the HMD and generates positional information describing the tracked position of the HMD. The transceiver communicates with a console via a wireless channel, in accordance with communication instructions, the communication instructions causing the transceiver to communicate over one directional beam of a plurality of directional beams. The beam controller determines a change in the positional information. Based on the change to the positional information, the beam controller determines a directional beam of the plurality of directional beams. The beam controller further generates the communication instructions identifying the determined directional beam, and provides the communication instructions to the transceiver.

Abstract: Embodiments relate to a method and a system for performing image compression and decompression of image data. In one or more embodiments, the image data is divided into one or more image data blocks, and the image compression and decompression are performed for each image data block. The image data block is compressed and includes a base value corresponding to a first image component and a compressed difference value corresponding to a second image component. For decompression, a first value of the image data block can be obtained based on the base value, and a second value of the image data block can be obtained based on the first value, the first compressed difference value and a corresponding quantization table. An output image can be presented to a user, according to the decompressed image data block.

Abstract: A method for detecting a screen tear in a display device for a given frame of video is described. The method includes retrieving an identification code associated with each pixel row of the frame of video and determining whether the retrieved identification code is same across pixel rows of the frame of video. If the identification code is found to be same across the pixel rows of the frame of video, no screen tear is found. On the other hand, a screen tear is detected if the identification code is found not to be same across the pixel rows. An indication of the detected screen tear is provided to the host machine to re-render the frame of video without such screen tear.
