高级电视系统委员会（Advanced Television Systems Committee, ATSC）是为数字电视制定一系列标
准的协会,ATSC数字电视标准包括高清晰数字电视、标准数字电视、数据广播、多声道环绕音频以及卫星数
字广播标准。目前采用ATSC的国家有美国、加拿大和韩国。 2009年美国将全面停止模拟电视的播
放,ATSC制数字电视的销量将会大幅度增长,因此,国内许多厂家纷纷瞄准了ATSC标准的数字电视产品的研发
。由于我国大部分数字电视工程师都具有一定的DVB产品的开发经验,而DVB和ATSC的标准虽然在原理上相
似,但实际的标准还是存在着很大的差异。 本文的主要目的是帮助DVB开发人员了解ATSC标准。
Advanced Television Systems Committee (Advanced Television Systems Committee, ATSC) is developing a series of standards for digital TV
Standards of the Association, ATSC digital TV standards, including high-definition digital television, standard digital TV, data broadcasting, multichannel surround audio, and satellite data
Word broadcasting standards. ATSC is currently the country with the United States, Canada and South Korea. 2009, the United States will stop all analog TV broadcast
Release, ATSC digital television system will be substantial growth in sales, so many domestic manufacturers have aimed at the ATSC standard digital television product development
. Since most of our engineers have a digital TV DVB certain product development experience, DVB and ATSC standards although in principle photogenic

人类从学会计数开始就一直和自然数打交道了，后来由于实践的需要，数的概念进一步扩充，自然数被叫做正整数，而把它们的相反数叫做负整数，介于正整数和负整数中间的中性数叫做0。它们合起来叫做整数。（注：现在，自然数的概念有了改变，包括正整数和0）
对于整数可以施行加、减、乘、除四种运算，叫做四则运算。又叫算术，它与几何学是最古老的两门数学分支。传统的几何学已经枯萎，而传统的数论（即算术）还有大量的问题无法解决。其中加法、减法和乘法这三种运算，在整数范围内可以毫无阻碍地进行。也就是说，任意两个或两个以上的整数相加、相减、相乘的时候，它们的和、差、积仍然是一个整数。但整数之间的除法在整数范围内并不一定能够无阻碍地进行，利用这一性质人们发明了大数密码体系。至今仍然关系着国家的安全。

Counting from the beginning of human society and the natural numbers have been dealing with, and later due to the needs of practice, the number of further expansion of the concept of natural number is called a positive integer, while the opposite of the number of them is called the negative integers, between positive integers and negative integers in the middle of the characteristic number is called 0. They together are called integers. (Note: At present, the concept of natural numbers have changed, including the positive integers, and 0) (2009-08-26, Pascal, 239KB, 下载5次)
人类，已在地球上生活了二三百万年。可是与恐龙的生存年代相比较，那还是一瞬间。在中生代，地球曾经是一个恐龙主宰的世界。无论是平原森林还是沼泽，到处都可以看到恐龙的身影。它们在地球上一共生存了一亿三千多万年。可是，不知为什么，后来恐龙竟然绝灭了，一个不剩地、永远地从地球上消失了。这实在是一宗千古疑案。
英国皇家植物园的一位生物化学分类学专家托尼·斯韦因坚决主张：有花植物的出现，改变了以植物为食的恐龙的食物成分，导致了整个恐龙的绝灭。他认为，在恐龙生存的中生代，植物界中的蕨类、苏铁、银杏、松、柏等裸子植物占着统治地位。谁料，约在一亿二千万年以前，最早的有花植物出现了，它们虽然把当时人类尚未出现的大地打扮得五彩缤纷、香气四溢，但却给恐龙带来了意想不到的灾难。因为，在有花植物的组织内，常常含有作用强烈的生物碱。恐龙有狼吞虎咽的不断嚼食的习惯，而且觉察不到自己的服毒，因此吞食了过量的生物碱毒素后，引起严重的生理失调，最后导致死亡。他指出，在欧洲发现的身体纤细、脖子较长的虚骨龙，死亡后的身躯之所以扭曲，主要是因为吃了过量的马钱子碱的缘故。
