Abstract
Deblocking filters used in video coding systems (e.g., single layer video coding systems or multi-layer video coding systems) may be enhanced. Inter layer prediction for scalable video coding (SVC) may be implemented using enhanced deblocking filters. Enhanced deblocking filters may be configured to be adapted, for example by adjusting a deblocking filter boundary strength calculation process. A deblocking filter boundary strength parameter may be assigned in accordance with, for example, a video block partition size of an input video block or a neighboring video block, whether an input video block or a neighboring video block was predicted using an inter layer reference, and/or whether at least one of an input video block or a neighboring video block have one or more corresponding base layer blocks that were coded using intra mode.
