Abstract: A video coding device (e.g., a video encoder or a video decoder) is configured to perform various transformations on video data. The video coding device applies a primary transform to a block of the video data, the primary transform having a first size, and the sub-block being at least a portion of the block. The video coding device determines whether application of a secondary transform, having a second size, to a sub-block of the block is allowed. Application of the secondary transform is disallowed when the first size is equal to the second size. Based on the application of the secondary transform being allowed, the video coding device applies the secondary transform to the sub-block. Application of the primary transform and the secondary transform construct a residual block in a pixel domain.

Abstract: A method of decoding a bitstream by an electronic device is provided. An image frame is received from the bitstream, and a block unit is determined from the image frame. A prediction index of the block unit is determined from the bitstream. A plurality of reference mode indices is determined based on a plurality of neighboring blocks of the block unit. The electronic device determines whether the reference mode indices are greater than a specific one of a plurality of non-angular mode indices. When the reference mode indices are greater than the specific non-angular mode index, the electronic device determines whether a difference between the reference mode indices is equal to two. When the difference is equal to two, a prediction mode is selected according to the prediction index and based on a first candidate list. Then, the block unit is reconstructed based on the prediction mode.

Abstract: Techniques are disclosed for managing memory allocations when coding video data according to multiple codec configurations. According to these techniques, devices may negotiate parameters of a coding session that include parameters of a plurality of different codec configurations that may be used during the coding session. A device may estimate sizes of decoded picture buffers for each of the negotiated codec configurations and allocate in its memory a portion of memory sized according to a largest size of the estimated decoded picture buffers. Thereafter, the devices may exchange coded video data. The exchange may involve decoding coded data of reference pictures and storing the decoded reference pictures in the allocated memory. During the coding session, the devices may toggle among the different negotiated codec configurations. As they do, reallocations of memory may be avoided.

Abstract: Consistent distributed edge models via controlled dropout model training are described. According to some embodiments, a machine learning model is trained using multiple sensor data streams. During the training process, ones of the sensor data streams are dropped to cause the model to be generated to be robust in that it can tolerate missing input data from sensor data sources yet still maintain high accuracy. The model can be deployed to multiple sensor devices within an environment. The sensor devices generate sensor data and exchange a variety of types of data to ultimately result in a distributed, consistent model result being generated that remains accurate despite communication faults that may occur between ones of the sensor devices.
