Abstract: Methods and systems for video image coding are provided. Sets of filters may be selected and applied to video information at least partially based on the type of inter layer prediction implemented in coding the video information. Different filters, or filter sets, may be used for inter layer intra prediction, difference domain intra prediction, and/or difference domain inter prediction. Filter selection information may be embedded in the video bit stream.
