Claim:
1. A method for decoding video data, the method comprising: receiving a serialized one-dimensional array of transform coefficients associated with a block of video data; determining a number of transform coefficients that are included in the serialized one-dimensional array and associated with the block of video data, wherein the number of transform coefficients is a quantity of the transform coefficients that are included in the serialized one-dimensional array; comparing the number of transform coefficients to a predetermined threshold number of transform coefficients; decoding, based on the number of transform coefficients exceeding the predetermined threshold number, at least one syntax element, separate from the transform coefficients, that indicates a scan order from a plurality of scan orders, wherein the scan order indicates an order in which the transform coefficients have been serialized from a two-dimensional array to the serialized one-dimensional array; determining the scan order based on the at least one syntax element; and inverse scanning the serialized one-dimensional array of transform coefficients to reconstruct the two-dimensional array of transform coefficients according to the determined scan order.
