Video Workshop is a digital video converter / editor for home video processing and for people who are just getting started with video editing.

视频讲习班是一个数字视频转换器/编辑器家用视频处理和人谁是刚刚起步，与视频编辑。

The history of video monitor technique has experienced three generations:first generation,traditional simulation video monitor system;second generation,hard disk - video tape recorder based video monitor system and the third generation,digital video monitor system based on compressing the video image at the place of signal resource.

纵观视频监控技术的发展历史，它主要经历了三代：第一代，传统模拟视频监控系统；第二代，基于硬盘录像机的视频监视系统；第三代，基于信源压缩的数字视频监控系统。

By generating all essential clock signals for MPEG playback, and converting digital video inputs to either NTSC or PAL video signals, the SP232EEN-L is an essential component of any low-cost solution for video-CD playback machines.

通过产生所有必要的MPEG播放时钟信号，并转换为数字视频输入或NTSC或PAL视频信号，SP232EEN - L是一个任何视频光盘播放机的低成本解决方案的重要组成部分。

ABSTRACT Video is an integral part of multimedia. Digital satellite broadcasting, desktop videoconferencing, video-CD playback, video-on-demand, Internet retailing, telebanking, and many other services will become ubiquitous by the turn of the century.

视频信息是多媒体的重要组成部分，卫星广播数字视频、会议电视、视频点播以及高清晰度电视都有着很好的市场潜力。

Unfortunately, movies are a bit dicier, as digital video is relatively new to the mix. The H.264 standard seems poised to emerge as a universal format, at least for HD video.

令人遗憾的是影视资料的保存有些风险，因为数字视频对大众来说是相对新的技术。H.264标准有成为通用的视频格式的趋势，至少是对于高清视频来说。

A Video Standard on laserdisc evolved into Video Essentials on DVD, followed by Digital Video Essentials on DVD and HD DVD.

视频标准的影碟演变成视频必备的DVD ，然后是数字视频产业的DVD和

Firstly it introduces relevant technical developments and trends, the task background and significance of the study, then analyzes hardware circuit of using image sensor as images collected, and utilizes the SAA7113 chip to deal with video image beforehand, SAA7113 lets the output of standard digital video signals to storage in FIFO memory, and decodes clock signals, Highlighted microprocessor control external circuit design of false coin and counting, and DSP control external circuit design, such as memory expand ect;Finally analyses CPLD as logic controller to control the logic and scheduling of some part ,and gives the undee emluator of some logic circuit.

文章首先阐述人民币智能分捡器相关技术的发展状况、发展趋势以及课题背景与研究意义；然后设计了利用图像传感器采集人民币图像输出模拟视频信号的硬件电路，以及利用视频解码芯片(SAA7113)对模拟视频图像进行预处理，SAA7113输出的标准数字视频信号存入FIFO存储器，同时还解码输出场、行同步信号、像素时钟信号送入CPLD等部分电路；重点设计了单片机控制验钞、点钞等外围电路，以及DSP控制的外围电路，如存储器的扩展等部分；最后完成CPLD对部分器件的逻辑和时序控制设计，并对逻辑电路的功能进行仿真，仿真结果令人满意。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
