stream rate meaning in English
串流率
流式率
Examples
- In recent years , fpga was paid more and more attention because of it ' s short development cycle , development fee . we also realize this bit - stream rate by fpga . the schedule of this algorithm was presented
近年来， fpga以其开发周期短、费用低越来越受到人们的关注，我们同样也用两片fpga ( xc2s50 , xc2s200 )芯片实现了该算法。 - After a great amount of detailed computer simulations and concise qualitative and quantitative theoretical analysis , the turbo codes " parameters and fpga specific hardware implementation architecture suitable for being integrated into dtv systems are determined . furthermore , the codec is completely designed with verilog hdl , ending with an occupation of less than a 600 - thousand - gate fpga chip . at this lowest hardware cost , a white noise snr threshold of 1 . 8db at a net stream rate of 6mbps is achieved , which exceeds all other existent dtv systems " performance
经过大量详细的计算机软件仿真和简明扼要的定性与定量的理论分析，最终确定了数字电视系统中适合采用的turbo码参数及针对fpga特殊构架的硬件实现结构，并用verilog硬件描述语言完成了turbo码编译码器的完整设计，以占用不到一片60万门fpga芯片的较少的硬件资源取得了在6mbps净码率下1 . 8db的白噪声信噪比门限这一远远超过现有任何数字电视系统的性能。 - Because of the different context of program and channel , most of the bit - stream rates of programs video are different . when one tv station relays other ' s program , or when we convert program from hfc to vod , tcp / ip system , it is need to convert the bit - stream rate which could not meet the need of local channel
由于节目内容不同、信道不同，数字电视系统中节目流码率是千差万别的，当一个电视台转播其它电视台的节目之前，或者将节目转播到点播电视系统、网络电视系统中时，如果本地信道不能满足带宽要求，则必需进行码率转换。 - At the same time , popular new methods and their latest situation were described . we put forward a new method of bit - stream rate of video - low pass filter and rate control algorithm . this method is easy to be realized and to meet the need of real time comparing with those popular ones , so it has more practical value
文章首先对传统的码率转换算法进行了简单叙述，指出了其弊端，同时讨论了人们为了克服此缺点而提出的各种码率转换算法，论述了当前国内外动态,然后在此基础上提出了一种新的码率转换算法- -低通滤波法，该算法与其它算法相比易于实现，能够满足实时性要求，具有较强的实用价值。
