Abstract: This disclosure is directed to systems and methods of streaming extensions for video encoding. The streaming extensions may enable the bitstream syntax for layered video data to be modified to reduce overhead for encoding. The bitstream syntax may be modified to enable variable length luma and chroma components, and enable the alignment between the layers and slice to be bit aligned to enable increased granularity in image encoding, and to minimize overhead between different elements within the layers.

Abstract: A device may include a display for displaying an image frame based on warped image data and image processing circuitry to generate the warped image data by warping input image data to account for one or more distortions associated with displaying the image. The image processing circuitry may include a two-stage cache architecture having an first cache and an second cache and warp the input image data by generating mapping data indicative of a warp between the input image space and the output image space and fetching the input image data to populate the first cache. Warping may also include populating the second cache with a grouping of pixel values from the first cache that are selected according to a sliding window that traverses the first cache based on the mapping data and interpolating between pixel values of the grouping to generate pixel values of the warped image data.

Abstract: This disclosure is directed to systems and methods of data partitioning in image encoding. A video encoder may receive a single stream of video data that includes multiple layers. The video encoder may encode the one or more layers utilizing multiple counters for each component within the layers. The multiple counters may correspond to the header bits, luma bits, and chroma bits within each slice layer. The encoded layers may then be assembled into a single slice before it is sent to a decoder for decoding of image frame.

Abstract: The present disclosure relates to systems and methods of multi-processing core processing of image frames during image encoding. The multiple processing cores may be connected via dedicated interfaces and transfer neighbor data between the processing cores to enable parallel processing of frame data. The multiple processing cores may each process quad-rows of image data for a single frame in parallel to reduce memory usage and mitigate latency in video encoding.

Abstract: A video encoding system in which pixel data is decomposed into frequency bands prior to encoding. The frequency bands are organized into blocks that are provided to a block-based encoder. The encoded frequency data is packetized and transmitted to a receiving device. On the receiving device, the encoded data is decoded to recover the frequency bands. Wavelet synthesis is then performed on the frequency bands to reconstruct the pixel data for display. The system may encode parts of frames (tiles or slices) using one or more encoders and transmit the encoded parts as they are ready. A pre-filter component may perform a lens warp on the pixel data prior to the wavelet transform.

Abstract: A video encoding system in which pixel data is decomposed into frequency bands prior to encoding. The frequency bands are organized into blocks that are provided to a block-based encoder that encodes the blocks and passes the encoded blocks to a wireless interface that packetizes the blocks for transmittal over a wireless connection.

The wireless interface may then transmit or drop packets according to the priority levels of the encoded frequency blocks in the packets and/or according to the timing information of the frequency blocks in the packets.
