Abstract: An apparatus for coding video data according to certain aspects includes a memory and a processor in communication with the memory. The memory stores the video data. The video data may include a base layer and an enhancement layer, the base layer including a base layer block and the enhancement layer including an enhancement layer block. The base layer block may be located at a position in the base layer corresponding to a position of the enhancement layer block in the enhancement layer. The processor determines, based on information associated with the base layer block, a partitioning mode of the enhancement layer block. The partitioning mode may indicate that the enhancement layer block is to be partitioned into a first partition and a second partition. The processor further performs motion compensation for the first partition and the second partition of the enhancement layer block.

Abstract: This disclosure pertains to video coding. Prediction information for a current block in an enhancement layer may be determined based at least in part on base layer information obtained by coding a base block in a base layer beneath the enhancement layer. This base block may occur in a position in the base layer such that it is co-located with a non-causal block in the enhancement layer (e.g., a block that occurs after the current block in the coding order of the enhancement layer). The prediction information determined for the current block may be used to code the current block (e.g., encoding or decoding the current block).

Abstract: In an example, aspects of this disclosure relate to a method for decoding a reference index syntax element in a video decoding process that includes decoding at least one bin of a reference index value with a context coding mode of a context-adaptive binary arithmetic coding (CABAC) process. The method also includes decoding, when the reference index value comprises more bins than the at least one bin coded with the context coded mode, at least another bin of the reference index value with a bypass coding mode of the CABAC process, and binarizing the reference index value.

Abstract: An apparatus for coding video information according to certain aspects is disclosed. Multi-layer video steams including a base layer and an enhancement layer can be coded. Predictors generated for the base layer and the enhancement layer can be combined to form a final predictor of the enhancement layer. Each predictor can be weighted such that those predictors which are more likely to produce high quality results can be factored more heavily in the final predictor. The conditions upon which the respective weights for enhancement layer predictors and base layer predictors are determined may be implicitly derived from the predictors or characteristics thereof. Alternatively, data may be generated explicating indicating the weights or providing information from which the weights can be determined.

Abstract: Techniques and systems are provided for compressing data in a neural network. For example, output data can be obtained from a node of the neural network. Re-arranged output data having a re-arranged scanning pattern can be generated. The re-arranged output data can be generated by re-arranging the output data into the re-arranged scanning pattern. One or more residual values can be determined for the re-arranged output data by applying a prediction mode to the re-arranged output data. The one or more residual values can then be compressed using a coding mode.

Abstract: Techniques are described for providing continuous control of a deblocking filter for a video block using a beta offset parameter. Deblocking filters are defined based on one or more deblocking decisions. Conventionally, a quantization parameter and a beta offset parameter are used to identify a beta parameter (“β”) value that determines threshold values of the deblocking decisions. The value of the beta offset parameter results in a change or increment of the β value. For small increments of the β value, rounding of the threshold values may result in no change and discontinuous control of the deblocking decisions. The techniques include calculating at least one deblocking decision for the deblocking filter according to a threshold value that has been modified based on a multiplier value of the beta offset parameter. The multiplier value applied to the beta offset parameter causes an integer change in the modified threshold value.

Abstract: In some embodiments of a video coder, if some prediction information is not available for a first block in a current layer, the video coder uses corresponding information (e.g., intra prediction direction and motion information), if available, from the first block's co-located second block in the base layer as if it were the prediction information for the first block. The corresponding information can then be used in the current layer to determine the prediction information of succeeding blocks in the current layer.
