Abstract：

The　AVS　video　coding　schemes,　which　is　developed　by　china,　uses　a　different　transform　(ICT)　than　before.　The　recently　completed　video　coding　standard,　H.264-AVC,　also　uses　an　integer　transform,　(HT).　In　this　paper,　we　propose　an　efficient　entirely　in　the　transform　domain.　We　show　that　the　conversion　is　essentially　a　2D　transform.　We　derive　the　transform　kernel　matrix　and　provide　a　fast　algorithm.　We　show　that　the　proposed　transform　domain　conversion　outperforms　the　conventional　pixel　domain　approach.　It　is　expected　to　have　applications　in　transform　domain　video　transcoding.　©2008　IEEE.
