    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: Systems and methods for determining information about an enhancement layer of digital video based on information included in a base layer of digital video are described. In one innovative aspect, an apparatus for coding digital video is provided. The apparatus includes a memory for storing a base layer of digital video information and an enhancement layer of digital video information. The apparatus determines a syntax element value for a portion of the enhancement layer based on a syntax element value for a corresponding portion of the base layer. Decoding devices and methods as well as corresponding encoding devices and methods are described.

    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.
