G.729 is an ITU-T ADPCM speech codec standard covering the transmission of voice at rates of 16, 24, 32, and 40 kbit/s. It was introduced to supersede both G.721, which covered ADPCM at 32 kbit/s, and G.723, which described ADPCM for 24 and 40 kbit/s. G.726 also introduced a new 16 kbit/s rate. The four bit rates associated with G.726 are often referred to by the bit size of a sample, which are 2-bits, 3-bits, 4-bits, and 5-bits respectively.

应用背景 rtp视频音频流传输;适用于多媒体rtp流通信; 此專題的目的是將遠端CCD與MIC取得的影像與聲音,壓縮成MPEG4 (Divx)格式，以RTP透過Multicast的方式，即時傳給多台電腦,實作平台都是WIN32 PC,最終目標是讓接收端不限於WIN32 PC,比如是WinCE PDA、Linux PDA等等,目前的平台著重於WIN32 PC。 关键技术 rtp协议           整個專題的成員總共有五人,工作分成三大部分,分別是RTP小組、多媒體檔案格式小組、Microsoft DirectShow小組,而我們小組主要負責的部分是Microsoft DirectShow部分,雖說工作是如此分的,在許多方面仍須去研究並了解,否則實作出的程式模組是無法結合的。

本例的功能是显示茶壶图像的景深效果。再连续5个茶壶的图像中，其中一个处于焦点处，其他的茶壶随着其焦点处的距离而逐渐变得模糊。-cases of this function is to show the depth of field teapot image effects. Another five consecutive images of teapots, which is a focus, other teapot with its focus away from the gradually become blurred.

Sox是最为著名的Open Source声音文件格式转换工具。已经被广泛移植到Dos、windows、OS2、Sun、Next、Unix、Linux等多个操作系统平台。Sox项目是由Lance Norskog创立的，后来被众多的开发者逐步完善，现在已经能够支持等多种声音文件格式和声音处理效果。基本上常见的声音格式都能够支持。更加有用的是，Sox能够进行声音滤波、采样频率转换，这对那些从事声讯平台开发或维护的朋友非常有用。当然，Sox里面也包括一些DSP算法，有兴趣的朋友可以下载回去研究。Sox可以用于任何用途。但是发布源代码时必须包括版权声明，发布二进制代码必须声明作者。-Sox is the most famous Open Source voice file format conversion tools. Has been widely transplant Dos, windows, OS2, Sun, Next, Unix, Linux and other operating system platforms. Sox was founded by Lance Norskog, later many developers have gradually improved. can now support multiple audio files formats and audio processing effects. Basically common formats can support. More useful is that the Sox to a voice filter, the sampling frequency conversion, This voice of those engaged in the development or maintenance of platforms friends very useful. Of course, the Sox also including some inside DSP Algorithm, interested friends can be downloaded to go back and study. Sox can be used for any other purpose. H

实现主流视频主观测试方法除以上方法之外的测试配置方法； 设计支持指定序列、地址、用户自定义播放顺序、重复播放次数、序列编号显示、定时播放序列、播放时间长度、打分提示信息、用户自定义视频播放帧率和分辨率以及测试配置的导入和导出。 -The realization of the mainstream video subjective test methods, in addition to the above configuration of the test method designed to support the designated sequence, address, user-defined playback sequence, the number of repeat players, serial number shows that broadcast regularly sequence the length of time to play, scoring message user-defined video frame rate and resolution as well as the test configuration of the import and export.
