电视系统

When the projection is placed behind a screen (as it is in television and various video conferencing applications where the image is displayed on a monitor or a fabric screen) it is described as a back projection system.

当投影仪放置在屏幕的后方时（就像电视中以及各种电视会议中使用的那样，图像被投影到监控器或编织物屏幕上），称为背面放映系统。

This implementation is based on AHB bus, it can demultiplex the transport steam with some different ways(the demultiplex process can be divided into some steps,the steam can be picked up from one of the steps).

这种实现方式是基于AHB总线的基础上，是SOC片上系统芯片中的一个子模块，可以灵活实现多种模式解析数字电视传输流，即将数字电视传输流解复用分为几个步骤，根据需要能够提取解析中不同阶段的码流。

Users' service area realizes lots of functions, such as users' registration and land in; inquire and dibble programs; comments, visit the network advertising and voting in the network.

为了提高观众对电视节目的参与性和互动性，提高电视节目的收视率和企业竞争力，发挥网络的方便性和快捷性，提出了网络互动节目管理系统的设计方案。

SDRAM is used as image storage, which can store many frames image data to provide the foundation for the correlation operation between frames. FIFO is a data buffer for real-time image. All of these make the image processing system simple design, decreasing the write-read time and solving the question of transmission and delay, and allowing the data processing and the data grabbing at the same time. The processed results can be output in 20ms, so the bandwidth of the C6000-based image processing system is improved.

系统采用SDRAM作为图像存储器，可以存储多帧图像数据，为实现帧相关运算奠定了基础，实时图像数据采用FIFO作为缓存，使系统设计简单，读取速度快，解决了数据传输的瓶径问题，同时也减少了传输延时，实现了对图像数据边采集边处理，减少了系统的滞后时间，当场给出电视脱靶量，提高了图像处理系统的带宽。

By using the fauna of digital television broadcasting channel, sue as mass data transmission, less resource occupied than Internet, and QoS guarantee, this system is de signed base on the Redbud DTV front-end sys tem developed by Shenzhen institute of Tsinghua university. The designed system is a low-cost data downloader using more simple protocols than current data broad cast.

利用数字电视广播信道可以实现大容量的数据传送，与互联网相比具有占用资源少、服务质量有保证等特点，在深圳清华大学研究院数字电视前端系统紫荆神网的基础上，设计实现了比现有数据广播协议更简便的低成本数据下载终端。

This paper used Windows 2000 Server as the system platform and SQL Server 2000 as the Database System. The DTVSMS is programmed via Java, using ODBC, RMI, Multi-Threading, Socket, Swing Components etc, which included Subscriber Management Module, Product Management Module, Device Management Module, Authorization Management Module, Message Management Module, System Management Module, Right Management Module etc.

本文以Windows 2000 Server为系统平台，采用SQL Server 2000大型数据库系统和JAVA编程语言，利用ODBC、RMI、多线程、Socket、Swing组件等编程技术，实现了包括用户管理、产品管理、设备管理、授权管理、消息管理、系统管理、权限管理等十几个模块的数字电视用户管理系统。

The HDMI Splitter can be used to duplicate the signal from your cable box so you can watch it on two televisions or to split the cable and plug directly into both the television and the home theater system.

的HDMI分配器可用于重复信号从您的有线电视机顶盒，您可以看电视或在两个分裂的电缆和插头直接插入电视和家庭影院系统。

Very simply put, it works in this way: through a sophisticated system of electronics, television provides the capability of converting an image

简单说来，电视是以这种方式工作的，通过一个复杂的电子系统，电视能够将一幅图像(这幅图像被聚焦在一部摄像机内的一块特殊的光导底片上)转换成能经过导线或电缆发送出去的电子脉冲信号。

In order to improve the inspection technologies of satellite interference, 5 kinds of technologies of satellite interference and integrated judgement-spectrum analysis, helix inspection, PID, S/N and signal vector were put forward. The automatic inspection system of interference of satellite TV has been built according to these inspected technologies and technology of network. The system adopts comparison of spectrum template, calibration of beaconing, mode identification, telemetering pick-up technology and improve the inspection technology of satellite interference. The alarm limits haw been defined through a lot of emulational tests, so that the system become feasible. The system has a good effect and makes up the blank of inspection technologies of interference in our country to some extent.

为了提高卫星干扰监测水平，提出了频谱监测、螺流监测、PID监测、S/N监测和信号矢量图监测等五种监测技术和干扰综合判断方法：根据这些技术手段和方法，并利用计算机网络技术，建立了卫星电视干扰信号自动监测系统；该系统利用网络化设计，采用频谱模板比对，卫星信标电平校准、信号模式识别、卫星遥测信号提取等技术，提高了卫星干扰监测的准确度和自动化程度；通过大最的仿真测试，设定告警门限，使系统的漏警率和误警率达到实用要求；该系统应用于干扰监测工作中，起到了很好的效果；在一定程度上弥补了国内通信干扰监测的空白。

Moreover, the infrared perimeter protection system, TV monitoring systems, access control card systems, window systems, such as magnetic and门磁should also be equipped.

此外，红外周边保护系统，电视监控系统，出入控制卡系统，窗口系统，如磁和门磁还应当配备。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
