1. A video decoding method comprising:
obtaining information identifying a first partitioning of a current block into a plurality of prediction units including at least one non-square, non-rectangular prediction unit, each prediction unit having an associated intra prediction mode;
determining a second partitioning of the current block into a plurality of transform units, wherein each transform unit is completely spatially contained within a respective one of the prediction units; and
decoding the current block according to the first partitioning and the second partitioning;
further comprising determining a scan order of the plurality of transform units, the scan order of the plurality of transform units being based on the first partitioning of the current block into the plurality of prediction units, such that a plurality of transform units that are spatially contained in a same one of the prediction units are all scanned before starting to scan transform units which are spatially contained in another one of the prediction units.
