1. A method for context adaptive entropy decoding, the method comprising: receiving coded data associated with a current block in a region, wherein the region corresponds to one or more rows of largest coding units (LCUs) and the coded data comprises a syntax element associated with a current luma intra mode of the current block; if a neighboring block of the current block is on an upper side of a horizontal boundary of the region or on a left side of a vertical boundary of the region, replacing block information associated with the neighboring block by DC mode; determining information for parsing the syntax element based on the block information associated with the neighboring blocks; and performing context adaptive entropy decoding of the syntax element based on the determined information.
