Abstract: An apparatus for coding video data using a single-loop decoding approach may include a memory unit and a processor in communication with the memory unit. In an embodiment, the memory unit stores the video data, the video data including a base layer and an enhancement layer. The base layer includes a base layer block, a non-constrained INTRA mode block, and an INTER mode block. The base layer block includes a sub-block located at least partially within one of the non-constrained INTRA mode block or the INTER mode block. The enhancement layer includes an enhancement layer block located at a position in the enhancement layer corresponding to a position of the base layer block in the base layer.

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 one embodiment, a video coder for coding video data includes a processor and a memory. The processor selects a filter set from a multiple filter sets for upsampling reference layer video data based at least on a prediction operation mode for enhanced layer video data and upsamples the reference layer video data using the selected filter set. Some of the multiple filter sets have some different filter characteristics from one another, and the upsampled reference layer video data has the same spatial resolution as the enhanced layer video data. The processor further codes the enhanced layer video data based at least on the upsampled reference layer video data and the prediction operation mode. The memory stores the upsampled reference layer video data.

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.
