Abstract
In one example, an apparatus is disclosed for coding coefficients associated with a block of video data during a video coding process, the apparatus comprising a video coder configured to code information that identifies a scanning order associated with the block, wherein to code the information that identifies the scanning order associated with the block, the video coder is configured to determine a most probable scanning order for the block, and code an indication of whether the scanning order associated with the block is the most probable scanning order. In another example, to code the information that identifies the scanning order associated with the block, the video coder is further configured to, in the event the scanning order associated with the block is not the most probable scanning order, code an indication of the scanning order associated with the block.
