ABSTRACT With developments of modern computer communication and display technologies today, video signal processing technology takes the world-shake changes. 2D video compression and transmission technologies develop almost maturate, and they are gradually applied in more and more fields.

中文摘要摘要随着计算机通信和显示技术的不断发展，视频信号处理技术也随之迅猛发展，其中的二维（2D）视频压缩传输技术几近成熟，并逐渐被应用在各个领域。

Compared to the ordinary PLL circuits, it can endure the short time appearance that occurs once in a horizontal line of the sync signal. It can adapt to the phase alternation character of a PAL video signal and recognize the phase alternation line. The local color sub-carrier can be generated for synchronous demodulation by the circuit.

该电路使用了全数字锁相环对色同步信号进行跟踪，与普通锁相环电路相比，它不仅能适应制视频信号中色同步信号每行出现一次和PAL制信号逐行倒相的特性，还能识别倒相开关信号，准确地产生本地色副载波用于同步解调。

This thesis introduces the design of DVB-T software receiver. We simulate the software receiver to demodulate the video signal from the IF signal of set top box.

本篇论文主要是利用从数位电视盒中频讯号的部份所取样出来的讯号，设计一个软体接收机将电视讯号解调回来。

ABSTRACT This thesis dicusses mainly analysis, design and development of the signal processing system and the coherent video signal simulat...

本文重点讨论三毫米脉冲雷达信号处理系统及其相干视频信号模拟器的系统分析设计及研制。

The design of the modern electronic device, except for must has multiple functions, but it also trend to achieve slightness, thinness, shortness and smallness in outer appearance. In order to seek such a trend, the components disposed in the electronic device must be reduced in volume correspondingly, and the connectors used therein also must be reduced in volume without exception. For example, the USB connector has developed a mini USB connector, and the digital video signal transmission interface evolves from a digital video interface to a high definition multi-media interface having a smaller volume and a faster transmission speed.

现代电子产品的设计除了要功能多样外，在外观上的趋势是追求轻、薄、短、小，为了追求这样的趋势，电子产品内的各个零件也必须跟着将体积缩小，其所使用的电连接器当然也不例外，如通用串行连接埠推出迷你版的通用串行连接端口，而数字影音讯号的传输接口也由数字视觉接口推演到体积较小，传输速度更快的高速高解析多媒体接口。

This number is a little deceptive because only 480 to 486 of these lines contain video information; the remaining 39to 45 lines are reserved for sync pulses to keep the television's circuits synchronized with the video signal.

因为在这些线中的只有80到486条包含了电视信号的数据；剩余39到45条行被同步脉冲保留用以维持电视能与信号一起同时被使用，所以这一个数字稍微具有一定的迷惑性。

Make a comprehensive view of the domestic industry, the visual talk-back system almost adopts simulate video technology to transmit video signal, this traditional manner has a good many abuse.

综观国内行业市场，目前的楼宇可视对讲系统大都是采用模拟视频技术传输视频信号，这种传统方式存在诸多弊端。

It is required in capture of video to synchronize the digitizing process with the parameters of the video signal .

在捕获视频信号时，需要用视频信号的参数实现数字化过程的同步。

In the digital video signal processing the technology of video moving object detection is very important.

视频运动目标检测是数字视频处理、分析应用的一个重要领域，在民用和军事上有着广泛的应用。

It is required in computer capture of video to synchronize the digitizing process with the parameters of the video signal .

在计算机捕获视频信号时，需要用视频信号的参数实现过程的同步。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
