EAC3 bit stream syntax允许在single bitstream中存在time-multiplexed substreams. 在EAC3的signle bitstream中,允许signle program大于5.1 channel,最大5.1ch的multi-program,或者5.1ch program和大于5.1ch program的混合. 一个EAC3的bitstream,必须包含至少一个independent substream. EAC3 bitstream可以o…

1.Spectral extension简介 Spectral extension是通过低频的transform coefficients合成高频transform coefficients的过程. spectral extension的实现与channel coupling类似,但是由于只需要transmit一些用于合成高频transform coefficients的metadat,因此比coupling更能减少datarate. 而且spectral extension能用于mono si…

Asterisk控制接口(AMI)允许管理客户端程序连接到一个asterisk实例并且可以通过TCP/IP流发送命令或读取事件.这在试图跟踪asterisk的状态或其中的电话客户端状态时很有用,AMI说明了客户端基于的一般(可能是动态的)规则.一种简单的"key: value"协议用于已连接的管理客户端和asteriskPBX之间的信息传递.每行都用回车换行(/r/n)来结束. 协议特点:        在发送命令前,你必须建立一个连接.在认证后,数据包任何时间都可以在两个方向上互相传…

  JCL: What is EXCP ?   EXCP stands for EXecute Channel Program. These are the I/O subsystem hardware driverprograms that do the actual data transfer between the DASD (Hard disk) and the system memory(core/RAM). Channels in mainframes are similar to…

至于要不要学Illustrator,完全凭个人意愿.如果你精通Coreldraw,学不学都一样.因为二者几乎可以完全替代. CDR:是一个纯图形设计软件.排版比其他二个软件好用. 一般来讲CDR更适合做Logo设计,AI更适合做UI,插画和艺术视觉创作. CorelDRAW和AI都是矢量处理软件CorelDRAW优缺点:1.CDR更好学些命令简单,快捷易用.2.而且在文字排版方面优秀.绘图功能更强.3.CorelDRAW方面定制图案比较便捷但是与PS兼容的不是很好,毕竟不是一个公司的产品.路径等…

配置Git Extension免密码发布代码到CSDN [本文默认大家安装了Git以及Git Extension] 今天花费了许多的时间处理这个问题,希望能给大家节约时间.闲话少说:使用ssh验证来push(上传)代码到code.csdn.net的优点在于避免每次都输入密码.步骤如下:1.使用git bush创建公钥.    但是注意一点,那就是git bush运行的默认目录必须是你的git档案库的目录,如何做到呢?    1.运行,CMD.调出那个黑乎乎的命令行    2. 通过命令行命令(各…

当我们引用第三方的DLL.或者Visual Studio自己的库的时候,或许会发现这样的一个情况,如果这个类型有一个XX的方法就好了.这时候我们可以用到扩展方法,是我们的代码更加灵活和高效. 这里我举例一下,比如在控制台程序(Console Application)我们想打印一个List<string>内所有的成员通常会怎么写么? 最通常的方法: List<string> StringList = new List<string>(); foreach (var ite…

四.Extension Method的本质 通过上面一节的介绍,我们知道了在C#中如何去定义一个Extension Method:它是定义在一个Static class中的.第一个Parameter标记为this关键字的Static Method.在这一节中,我们来进一步认识Extension Method. 和C# 3.0的其他新特性相似,Extension Method仅仅是C#这种.NET Programming Language的新特性而已.我们知道,C#是一种典型的编译型的语言,我们编…

在C#3.0中,引入了一些列新的特性,比如: Implicitly typed local variable, Extension method,Lambda expression, Object initializer, Anonymous type, Implicitly typed array, Query expression, Expression tree. 个人觉得在这一系列新特性的,最具创新意义的还是Extension method,它从根本上解决了这样的问题:在保持现有Type…

这一节,是要把AS库和Android的jar包及相关配置文件打成一个ane包. 首先先建一个build目录,里面文件目录结构如下: 然后用打开压缩包的方式打开ServiceLib.swc, 把其中的library.swf解压到 android 文件夹下, 把之前生成的jar包也放在这个文件夹下: (注意ServiceLib.swc 必须完整地放在根目录, 相当于复制了一份library.swf到android文件夹下) 同理,把ServiceLibDefault.swf的library.swf…
