rate distortion model

基本解释

We then present a simple but effective rate-distortion model for video transcoder.
接下来，本文提出了一种初步但有效的转码率失真模型。
Generally, the rate distortion model is employed to compute quantization parameter for the controlling bit rate.
通常码率控制算法使用一定的率失真模型来决策量化参数从而控制码率。
The multi-resolution motion estimation scheme and an efficient rate-distortion model are adopted with early termination rules to accelerate the search process.
此算法基于多分辨率运动估计方案和新率失真模型进行预测模式快速选择，并结合带提前退出准则的快速搜索算法来加速搜索过程。
