由於近年來科技的發達導致人類社會結構的變遷，視訊這個名詞已經不再陌生。多媒體相關研究的蓬勃發展亦帶動許多3C產業活動的顛峰，並且結合學術的探討與業界的技術應用在人們的日常生活裡。

本論文在研究H.264視訊串流之相關技術與應用，技術方面使用HARQ、重傳機制等方法將其應用在嵌入式系統裡，並以無線通訊來做為傳輸環境。文中提出兩種方法將其optimizatized，分別是最大權重分配和動態規劃。

視訊串流的主要突破在於速率-失真技術的最佳化，亦即考慮速率-失真函數時，同時考慮資料封包的重要性以及傳輸通道的通道情況。

The video is not unknown,because the devolop of technology changes human society. Research and development of multimedia also to push the 3C industy,it joint research of science and application of industy with people life.
The paper is to discuss technology and application of H.264 vedio streaming, method of HARQ we used to apply in embedded system,and transmit in wireless communications.Maximum weight matching and multipath are the ways to arrive optimizatized.
Vedio streaming is focus on Rate-Distortion optimizatized,it means consider the importance of data packet and the condition of wireless channel.
