In　the　latest　video　coding　standard　H.264,　intra　frame　prediction　is　employed　to　reduce　the　blocks＇　spatial　correlation.　In　this　paper,　a　new　algorithm　is　proposed　to　improve　the　performance　of　intra　prediction　of　H.264/AVC.　It　changes　mode　2　of　H.264＇s　standard　prediction　methods　into　a　BMA　(block-matching　algorithm)-DC　hydrid　mode.　Experiment　results　show　that　with　the　proposed　algorithm,　significant　improvement　of　coding　performance　can　be　gained　compared　to　the　performance　of　H.264　algorithm.
