Claim Text:
1. A method of coding transform coefficients associated with a first block of video data during a video coding process, wherein the first block has a non-square shape defined by a width and a height, and wherein one of the width or height of the block equals “1” block position, the method comprising: coding, with a video coder, one or more of x- or y-coordinates that indicate a position of a last non-zero coefficient within the first block according to a scanning order associated with the block determining, with the video coder, that the one of the width or the height comprises a single block position; determining, with the video coder, one or more contexts used to code a respective x- or y-coordinate based at least in part on one of the width or the height of the block not having the single block position that corresponds to the respective x- or y-coordinate; coding the respective x- or y-coordinate by performing a context adaptive entropy coding process based at least in part on the determined one or more contexts; and not coding, with the video coder, the respective x- or y-coordinate corresponding to the width or height of the block having the single block position.
