  1. H.264 Motion Estimation Implement in Equator DSPShu-Fan Chang2003/10/29 音 視 訊 專 題

  2. H.264 Motion Estimation Implement in Equator DSP • 在既有的Euqator DSP的H.263程式中，將原本H.263的Motion Estimation (移動預估)方式，置換成H.264的Motion Estimation 。 • What’s the Motion Estimation ?

  3. Motion Estimation • 主要的目的，是要消除視訊畫面在時間上的相關性，移動預估演算法的好壞，對整個視訊壓縮品質有極大的影響。 motion vector Best-matched candidate block 待編碼區塊 search area previous frame time current frame

  4. Tools • 硬體部分 採用美國Equator公司和日本日立公司聯合開發的寬帶高速媒體處理器Equator MAP-CA DSP。 • 軟體方面 MAP-CA可以完全用C語言編程，不需要任何低階語言。

  5. 人 員 需 求 • Video Codeing 有深厚興趣者 • C語言有相當基礎者或肯下工夫學習C語言者 • 對於閱讀英文文件無恐懼症者
