Claim Text:
1. A method of decoding video data, the method comprising: decoding data indicating whether tile boundaries of different layers of video data are aligned and whether inter-layer prediction is allowed along or across tile boundaries of enhancement layer blocks, wherein the tile boundaries occur between tiles of the different layers, wherein each of the tiles comprises a respective integer number of coding tree blocks co-occurring in one column and one row, ordered consecutively in coding tree block raster scan of the corresponding tile, and wherein pictures of the different layers include at least two tiles; decoding one of the enhancement layer blocks in an enhancement layer tile of the video data, wherein when the data indicates that tile boundaries of different layers are aligned and that inter-layer prediction is allowed, decoding the enhancement layer block comprises decoding the enhancement layer block without using inter-layer prediction from a collocated base layer block for which inter-layer filtering or reference layer filtering across tile boundaries in a reference layer picture in an access unit including both the enhancement layer tile and the base layer block is enabled; and decoding the collocated base layer block, wherein decoding the collocated base layer block comprises decoding the collocated base layer block in parallel with decoding the enhancement layer block when inter-layer filtering or reference layer filtering across tile boundaries in the reference layer picture is enabled.
