For video codec, after analyzing and researching the newest standard h. 264, an efficiency algorithm was proposed in this paper using self - feature, spatial correlation and temporal correlation to judge the encoding mode of one macro - block. through this method, the best prediction mode can be obtain before encoding, then, the coding time can be reduced dramatically with a little expense of bit - rate. for video transmission, in this paper, a transmit method was proposed using tcp / ip protocol under the environment of local networks
首先，在分析及研究最新的視頻編碼標準h . 264的基礎上，利用宏塊自身的特點和其時間、空間的相關性來判斷宏塊應該採用的編碼模式，從而提前得到該宏塊的最佳編碼模式，新方法有效地克服了原標準演算法中窮舉式的復雜演算法，在壓縮碼流只有少許增加的情況下，大幅度地提高了幀內及幀間編碼的速度。 -
