The method maximizes the average PSNR of the whole video sequence or minimizes the overall distortion, subject to the bit rate constraint.
该法是在给定的速率限制下，使整个视频序列的平均峰值信噪比（PSNR）最大，也就是使序列的总体失真最小。
Multiple sub-layers of texture information are generated based on their rate distortion function, the number of which is adjusted dynamically by the encoder according to the feedback information to minimize the overall distortion.
编码器根据反映信道状态的反馈信息动态地调整传输的子层数目和每个子层的纠错强度（信道编码速率），使得系统失真最小。人物形象发生了严重的扭曲和变形；
This paper presents overall discussion on the key elements in the optical fiber AM CATV externally modulated transmitter, including demand on light source, choice of modulator, nonlinearity and compensation, clipping distortion and compensation, close loop control on CSO. CTB etc.
就光纤AMCATV外调制发射机的关键问题，即光源的选择、调制器的选择、非线性补偿、限幅失真抑制及CSO和CTB的闭环控制进行了较全面的论述。
