    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 example, 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. The processor approximates pixel values of the sub-block and determines, based at least in part on the approximated pixel values, pixel values of the enhancement layer 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: The disclosure provides a system and methods for encoding video data. The method can include storing a data structure in a memory, the data structure having a first plurality of data elements arranged corresponding to a second plurality of data elements of a first video data block, and defining a periphery, the data structure further including data related to all of a smallest prediction unit (PU) for the first video data block. The method can also include increasing a size of the data structure in the memory by adding a plurality of extended units along the periphery of the first plurality of data elements, each extended unit having data related to a smallest data element of the first video data block, the extended units being set to default values. The method can also comprise encoding the first video data block based on the data structure.

    Abstract: Systems, methods, and devices for coding video data are described herein. In some aspects, a memory is configured to store the video data associated with a base layer and an enhancement layer.
