Abstract
In one embodiment, an apparatus configured to encode video information includes a memory unit and a processor. The memory unit is configured to store an inter-layer reference picture comprising video information. The processor is operationally coupled to the memory unit. In addition, the processor is configured to partition the inter-layer reference picture into a quadtree structure having a plurality of leafs; determine inter-component filter parameters specific to each individual leaf based upon the video information in each individual leaf and signal the inter-component filter parameters for each of the leafs.

An apparatus configured to encode video information, the apparatus comprising:
- a memory unit configured to store an inter-layer reference picture comprising video information;
- and
- a processor operationally coupled to the memory and configured to:
- partition the inter-layer reference picture into a quadtree structure having a plurality of leafs;
- determine inter-component filter parameters specific to each individual leaf based upon the video information in each individual leaf, wherein the inter-component filter parameters comprise at least one of a high-pass filter coefficient, a quantization parameter, or a shift parameter;
- and
- signal the inter-component filter parameters for each of the leafs.
A method of encoding video information, the method comprising:
- storing an inter-layer reference picture comprising video information;
- partitioning the inter-layer reference picture into a quadtree structure having a plurality of leafs;
- determining inter-component filter parameters specific to each individual leaf based upon the video information in each individual leaf, wherein the inter-component filter parameters comprise at least one of a high-pass filter coefficient, a quantization parameter, or a shift parameter;
- and
- signaling the inter-component filter parameters for each of the leafs.
An apparatus configured to decode video information, the apparatus comprising:
- a memory unit configured to store an inter-layer reference picture comprising video information;
- and
- a processor operationally coupled to the memory and configured to:
- determine partition information indicating a quadtree structure having a plurality of leafs into which the inter-layer reference picture is partitioned;
- determine inter-component filter parameters specific to each individual leaf, wherein the inter-component filter parameters for each individual leaf are based upon the video information in the individual leaf and comprise at least one of a high-pass filter coefficient, a quantization parameter, or a shift parameter;
- and
- decode the inter-layer reference picture using the partition information and the inter-component filter parameters.
