By evaluating the channel distortion and source distortion of all macroblock modes, the optimal macroblock mode is selected adaptively to minimize transmission distortion.
通过估算不同宏块模式的信源失真和信道失真,自适应地选择最佳编码模式,使得视频序列的整体传输失真最小。

In this mode, four bottom pixels from the block above are copied vertically into part of an intra-coded macroblock.
在这种模式中,上方像素块中的四个底部像素被垂直拷贝至经过帧内编码的宏块中。
In order to gain the optimal mode, H. 264 adopts Rate Distortion Optimization (RDO) technique to compute the cost of every mode for each macroblock, but it increases computational complexity.
为了得到最优模式,H . 264采用了率失真优化(rdo)技术计算宏块的每种模式的代价,但是这样增加了计算复杂度。
In this mode, eight bottom pixels from the blocks above are copied diagonally into part of an intra-coded macroblock.
在这种模式中,上方像素块中的八个底部像素被沿对角线方向拷贝至经过帧内编码的宏块中。
