Abstract

See full text

A method of de-blocking video data is disclosed. The video data encoding color channels in a 4:2:2 format is received. The video data is encoded in a quad-tree. A plurality of transform units is generated for one of the color channels, each of the transform units including at least one transform. A distance from an edge of one of the transform units to a boundary of a transform of the transform unit is determined. An edge flag for the transform unit is determined, the edge flag indicating the determined distance. De-blocking is applied to the transform units of the video data according to the determined edge flag.
