dc.description.abstract	H.264/AVC是一個可以達到比現在最被廣泛使用的MPEG-2視訊壓縮標準更高效率的視訊編碼，在這篇論文，我們提出了一個快速的演算法，以加快MPEG-2到H.264/AVC的轉換編碼的速度，這演算法包括了一個針對H.264提供的不同區塊大小的有效選擇方法以及快速決定這些區塊的移動向量的方法，實驗結果顯示所提出的演算法在與完整的MPEG-2到H.264的轉換標碼比較時，可以降低大量的計算時間且保持相同的影像品質。	zh_TW
dc.description.abstract	The H.264/AVC standard can achieve much higher coding efficiency than the widely available MPEG-2 video standard. In this thesis, we proposed a fast algorithm in order to speed up MPEG-2 to H.264/AVC transcoding time. The proposed algorithm includes a fast mode decision method for the variable-sizes blocks in H.264 and a fast motion vector decision method for these blocks. The Experiment results show the proposed algorithm can reduce much computational cost with keeping similar video quality while compared with full MPEG-2 to H.264 transcoder.	en_US
