Abstract

A video coder associates a first boundary strength value with an edge in response to determining that a first video block or a second video block is associated with an intra predicted coding unit (CU) where the edge occurs at a boundary between the first video block and the second video block. The video coder may associate a second or a third boundary strength value with the edge when neither the first video block nor the second video block is associated with an intra predicted CU. The video coder may apply 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. The third boundary strength value indicates that the deblocking filters are turned off for the samples associated with the edge.
