Systems and Methods for Multi-Pipe Scheduling During Image Decoding
20230079090 · 2023-03-16 ·

The present disclosure relates to systems and methods of multi-pipe scheduling for image decoding. For example, a bitstream may include compressed slices that are scheduled to each of the multiple decoding pipelines present in the image processing circuitry of an electronic device. The bitstream may include image data that was encoded using variable-length coding. This results in some bits of the image data containing denser and/or sparser syntax elements and result in variable processing times. The scheduling circuitry may be able to monitor each of the multiple decoder pipelines rate of bit consumption and the number of bits initially scheduled to each of the multiple pipelines and the number of bits consumed by each of the multiple pipelines over time so that incoming compressed slices may be scheduled to the pipe that will be able to process the compressed slice the fastest.

Device with dynamic transcode throttling

Dynamic transcode throttling methods and devices for processing resource management and thermal mitigation in electronic devices such as eyewear devices. An electronic device monitors its temperature and, responsive to the temperature, configures a transcoding service to operate at different rates. A frame delay module is configured to add a delay between read frames prior to the transcoding service. This enables the electronic device to consume less power when temperatures are too high in order to provide thermal mitigation and can be performed without powering down the electronic device.

Systems and methods for enhanced video encoding
11606562 · 2023-03-14 · ·

Systems and methods for enhanced video encoding identify patterns in sequences of raw digital video frames to extract features and identify the type of content represented by the extracted features. The system simulates many outcomes of encoding the sequence of digital video frames by using various different encoding strategies to find the relative best encoding strategy for each sequence of frames. As the encoder processes video, it passes digital video frames to a modeling system which determines whether the video, or video having that same type of content, has been previously observed by the system. The system then selectively applies a saved encoding strategy that had been determined by the system to be particularly suitable for encoding the same sequence of video frames or that same type of content.

Directed interpolation and data post-processing

An encoding device evaluates a plurality of processing and/or post-processing algorithms and/or methods to be applied to a video stream, and signals a selected method, algorithm, class or category of methods/algorithms either in an encoded bitstream or as side information related to the encoded bitstream. A decoding device or post-processor utilizes the signaled algorithm or selects an algorithm/method based on the signaled method or algorithm. The selection is based, for example, on availability of the algorithm/method at the decoder/post-processor and/or cost of implementation. The video stream may comprise, for example, downsampled multiplexed stereoscopic images and the selected algorithm may include any of upconversion and/or error correction techniques that contribute to a restoration of the downsampled images.
