Recently, ITU-T VCEG and ISO/IEC MPEG have started a new joint standardization activity on video coding, called High Efficiency Video Coding (HEVC). In this paper, the new transform coding techniques in the HEVC Test Model are de- scribed, including the residual quadtree (RQT) approach and coded block pattern signaling. Experimental results showing the advantage of using larger block size transforms, especially for high resolution video material, are presented. Furthermore, the trade-off between coding gain and encoder complexity in terms of the maximum RQT depth is discussed.
