本文的第二个贡献是，针对SVC的编码模式选择，我们考察了在具有丢失感知的率失真优化中拉格朗日乘子的选择方法。
In the second contribution, we formulate mode decision of loss-aware rate distortion optimization (LA-RDO) with Lagrange multiplier selection in SVC scenarios.
突然之间所有的事物都变成了一种模式，从持有一个编码标准到支持代码走查以及选择一个程序设计的语言。
Suddenly everything is a pattern, from having a coding standard to holding code reviews and selecting a programming language.
首先，它有两种模式(即可以由编码器选择)：快速模式和普通模式。
First, it has two modes (which can be chosen by the encoder) : a fast mode and a normal mode.
“自上而下”和“自下而上”宏块划分模式选择算法首先作为编码器的快速算法被提出。
The top-down and bottom-up mode selection schemes were first introduced as fast mode decision algorithms for video encoders.
提出一种H . 264编码中帧间模式选择的算法，利用帧与帧之间的时间相关性并提出通过模式识别中统计分类的方法对帧间宏块模式进行分类。
In this paper, we have proposed an inter-mode selection algorithm for H. 264, which is based on the time-relativity of the neighboring frames and adopts the idea of statistic classification.
同时，本文还分析了利用率失真优化选择算法在各种编码、预测模式中进行选择的基本原理和实施。
The so called rate-distortion optimization selection method being applied in H. 264 for selecting the best mode between many choices is also discussed in this paper.
实验表明，与全模式选择算法相比，采用该算法编码速度可以提高2 ~4倍，而且重建质量和编码效率损失极小。
Experimental results show that the speed of the proposed method is about 2 -4 times faster than the full-mode decision algorithm without any noticeable loss of image quality and coding efficiency.
