Abstract:
1. A method of coding video data, the method comprising: associating, without determining whether an edge between a first video block and a second video block is a coding unit (CU) edge, a first boundary strength value with the edge in response to determining that the first video block or the second video block is associated with an intra-predicted CU; associating a second boundary strength value with the edge in response to determining that the first video block and the second video block are not associated with an intra-predicted CU and that the first video block or the second video block is associated with a transform unit (TU) with a non-zero transform coefficient level; associating either the second boundary strength value or a third boundary strength value with the edge when the first video block and the second video block are not associated with an intra-predicted CU and the first video block and the second video block are not associated with a TU with a non-zero transform coefficient level, wherein the second boundary strength value is associated with the edge when one or more of the following additional conditions are satisfied: applying one or more deblocking filters to samples associated with the edge when the edge is associated with the first boundary strength value or the second boundary strength value, but not the third boundary strength value.
