Abstract:
A method for coding a transform block of coefficients includes generating a new scan order from the original scan order such that a maximum scan distance of the new scan order is smaller than or equal to a predetermined distance, and coding the coefficients based on the new scan order. An apparatus for decoding a transform block of coefficients. The apparatus includes a memory and a processor. The memory includes instructions executable by the processor to identify an original scan order for encoding the coefficients, generate a new scan order from the original scan order such that a maximum scan distance of the new scan order is less than or equal to a predetermined distance, and decode, from an encoded bitstream, the coefficients based on the new scan order.

Claim (Index 10):
The apparatus of  claim 8 , wherein to generate the new scan order comprises to:\n assign a new scan index to a current coefficient,\n the current coefficient being immediately followed by a next coefficient in the original scan order, and \n the current coefficient being a context coefficient for entropy coding another coefficient; and \n on condition that a scan distance of the other coefficient is greater than or equal to a conservative maximum distance, assign a next scan index to the other coefficient before assigning the next scan index to the next coefficient.
