          <dc:description>放送基盤向け HDTV 対応 H.264／AVC High422 プロファイル符号化 LSI ， ”SARA／E” を開発した． SARA／E は，現在，放送素材伝送で用いられている MPEG-2 422 プロファイルにも対応している．独自の 3 つの動き検出／動き補償エンジンにより， -217.75 から＋199.75 (水平方向) ／-109.75から＋145.75 (垂直方向) という広範囲の探索範囲を実現するとともに，Ｈ.264／AVC で規定されているほとんどすべての ME／MC 符号化ツールを利用可能である．実験によると，動きの速いシーンにおいて 1.2 dB から 1.7 dB の画質向上を達成している． SARA／E は90 nm プロセスで 1 億 4 千万トランジスタを集積している．</dc:description>
          <dc:description>An H.264/AVC encoder LSI (named "SARA/E") that supports High422 profile, as well as 422 profile of MPEG-2, has been developed for HDTV broadcasting infrastructures. It contains three motion estimation and compensation (ME/MC) engines with search ranges of -217.75 to +199.75 (H) / -109.75 to +145.75 (V), which can utilize almost all H.264/AVC ME/MC tools, multiple reference frame, variable block size, 0.25-pel prediction, macroblock adaptive field/frame prediction (MBAFF), temporal/spatial direct mode, and weighted prediction. Our evaluations show that it can encode fast moving scenes with 1.2 dB to 1.7 dB higher than the JM. It was successfully fabricated in a 90 nm technology. It integrates 140 million transisters.</dc:description>
