Abstract: An apparatus for coding video information according to certain aspects includes a memory unit and a processor in communication with the memory unit. The memory unit stores video information of a reference layer. The processor determines a value of a video unit based at least in part on a prediction value and an adjusted residual prediction value associated with the reference layer. The adjusted residual prediction value is equal to a residual prediction from the reference layer multiplied by a weighting factor that is different from 1.

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: A video encoding device is configured to generate a first group of syntax elements. Each syntax element in the first group indicates whether a prediction mode of a respective prediction unit (PU) is based on an index into a list of most probable modes. A second group of syntax elements is generated that correspond to respective syntax elements in the first group. The syntax elements in the second group identify either an index into the list of most probable modes or an intra-prediction mode. The first group of syntax elements are context adaptive binary arithmetic coding (CABAC) encoded, and the second group of syntax elements are bypass encoded. A video decoder is configured to receive the entropy encoded first and second groups of syntax elements. The video decoder CABAC decodes the first group of flags and bypass decodes the second group of flags.

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: In general, this disclosure describes techniques for improved inter-view residual prediction (IVRP) in three-dimensional video coding. These techniques include determining IVRP availability based on coded block flags and coding modes of residual reference blocks, disallowing IVRP coding when a block is inter-view predicted, using picture order count (POC) values to determine whether IVRP is permitted, applying IVRP to prediction units (PUs) rather than coding units (CUs), inferring values of IVRP flags when a block is skip or merge mode coded, using an IVRP flag of a neighboring block to determine context for coding an IVRP flag of a current block, and avoiding resetting of samples of a residual reference block to zeros during generation.

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.
