变长编码 meaning in Chinese
variable-length encoding
Examples
- 4 marpe d , schwarz h , wiegand t . context - based adaptive binary arithmetic coding in the h . 264 avc video compression standard . ieee trans
变长编码实现简单计算复杂性低，因此在视频编码标准及消费电子产品中被广泛采用。 - Joint video team of iso iec jtc1 sc29 wg11 itu - t sg16 q . 6 doc . , klagenfurt , austria , july 2002 , jvt - d034 . 12 final draft of information technology - advanced coding of audio and video - part 2 : video
本文的基于上下文的变长编码方法c2dvlc获得了更高的编码效率，相比于mpeg - 2的2d - vlc熵编码器，在一些典型的高清标清测试序列上，编码效率平均提高0 . 34db ，与h . 264的cavlc相比，编码效率相当。 - Based on the specialty of flexible processing enterprise , we designed and developed production planning system of processing err at last , a genetic algorithm based on variable length coding for the scroll cutting problem in production planning system is proposed
针对柔性流程企业生产计划的特点，设计实现流程erp的排产计划系统，并提出了一种基于变长编码遗传算法以解决生产计划中的纸卷切割问题。 - Then some key techniques in mpeg - 2 and mpeg - 4 recommendations are studied and compared in detail , including motion estimation , motion compensation , discrete cosine transform , inverse discrete cosine transform , variable length coding and layered description of picture and code stream
然后深入研究了mpeg - 2建议的视频编码标准，包括ts流、 ps流、时钟恢复、视频与音频的同步、基于场的运动补偿、 dct及变长编码。 - The characteristic of h . 264 standard can be concluded mainly into three aspects . it is more practicable , more adaptive to ip net and mobile system and it improves the key components of coding structure based on hybrid video coding framework . for example , it adds coding mode decision , multi frame prediction , context - based adaptive variable length coding ( cavlc ) , 4x4 integer transform , loopfilter , etc . the improvement in performance leads to higher computational complexity in the new standard
H . 264的技术特点可以归纳为三个方面，一是注重实用；二是注重对移动和ip网络的适应；三是在混合编码器的基本框架下，对其主要关键部件都做了重大改进，如多模式运动估计、帧内预测、多帧预测、基于内容的变长编码、 4 4二维整数变换等。
