Abstract:
Coding a transform block using level maps is disclosed. A method includes determining a lower plane of values, processing the lower plane in a backward scan order, and selecting a template for entropy-coding the values of the lower plane. The method also includes, for a current value of the lower plane, selecting, based on the template anti-diagonal lines, two or more line buffers, each of the two or more line buffers corresponding to a respective scan-order anti-diagonal line, determining a context using the two or more line buffers, and entropy encoding the current value using the context. Each value is a respective “up-to” value of a transform coefficient. The backward scan order visits the values of the lower plane along scan-order anti-diagonal lines. The template indicates scan positions of coded values of the lower plane, the scan positions are arranged, in the template, along template anti-diagonal lines.

Claim (Index 4):
The apparatus of  claim 1 , wherein the template comprises seven scan positions arranged along three template anti-diagonal lines,\n wherein a first template anti-diagonal line includes at least two scan positions of the seven scan positions, a second template anti-diagonal line includes at least three scan positions of the seven scan positions, and a third template anti-diagonal line includes at least four scan positions of the seven scan positions, and wherein each of the at least two scan positions, the at least three scan positions, and the at least four scan positions being a different scan position.
