Abstract: Compression techniques are described. In an embodiment, a first plane of sensor data is accessed, the first plane of sensor data is divided into a plurality of slices, each sample is encoded in each slice from the plurality of slices, where encoding a sample include computing a median based prediction for the sample, computing an error for the sample comprising a difference between the sample and the computed median based prediction, determining a context for the sample, selecting a model for the sample by using the determined context, and encoding the computed error by using the selected model.

Abstract: A source electronic device may include first interface circuitry that transmits a data packet over a wireless link to a sink electronic device to present the data packet as part of a video stream. The source electronic device may also include encoder circuitry that encodes the data packet for transmission through the wireless link and a feedback path communicatively coupling the encoder circuitry directly to the first interface circuitry. The feedback path may transmit one or more feedback signals from the first interface circuitry to the encoder circuitry, bypassing a network layer, an encoder driver, or both. The encoder circuitry, the first interface circuitry, or both may adjust one or more transmission parameters associated with transmitting the data packet over the wireless link, based on the one or more feedback signals.

Abstract: In one implementation, a method of encoding an image is performed at a device including one or more processors and non-transitory memory. The method includes determining a category of a spatial portion of an image based on a relation between a plurality of thresholds associated with a plurality of quantization scaling parameters and a bit rate of the spatial portion of the image at the plurality of quantization scaling parameters. The method includes quantizing the spatial portion of the image based on the categorization.

Abstract: Systems and methods of parallel image parsing and processing for video decoding are provided. Video decoder circuitry may enable an incoming encoded bitstream to be split into multiple bitstreams corresponding to the bitstream compression scheme and processed by multiple parsers corresponding to the bitstream compression scheme in parallel. This enables parallel decoding of the incoming bitstream and, thus, more efficient decoder processing.
