Abstract

A method for high efficiency video coding comprises the steps of selecting an intra-prediction mode for a high efficiency video coding prediction unit, and responsive to the selected intra­ prediction mode, selecting one of a plurality of predetermined orders of transform unit processing, and processing respective transform units in the selected predetermined order. The intra prediction mode may be selected from a Z-scan order, a vertically inverted Z-scan order or vertically and horizontally inverted Z-scan order dependent on the angle corresponding to the prediction mode selected.
