卫星的好处是很清晰(数字信号,当然现在也有DIGITAL CABLE),即使不是HIGH DEFINITION的RECEIVER(个人认为TOO EXPENSIVE,现在没必要,除非你是"发烧友"),节目选择也比较多,但每个电视都要买一个RECEIVER.当然你也可以用一个RECEIVER,但所有电视同时只能看同样的频道.关于天气对卫星电视的影响,一般来说下雨没什么影响,下大雪可能会中断信号.这个冬天以来,我只碰到过两次信号中断的现象,NO BIG DEAL. |

You must be working for rogers, they had a commercial just like what you said.
![]() In fact, satellite signals are much clearer than cable signals because it is digital. The effect of weather on the satellite signals? Virtually none. Satellite highspeed? For what I know, it's only used in areas where no cable or adsl is available, AND uploading is still dialup speed. 引用:

Yes they drilled a hole through the siding to my basement. It's just a small hole that's big enough for the wire to come in, but it's a free installation. Such upgrade would probably cost you at least 100 bucks.
I'm also curious to know, how could the builder make the wire available for hookup? 引用:

渐渐说得对,数字信号不象模拟信号有干扰的现象(雪花),但信号可能中断,要么有,要么没有,that's it.

It's not the builder. It's the security monitoring companies that can do this kind of wiring.

关于第二个问题,我不知道,因为我不看中文电视.但我想如果你要看中文的话,不管用那个卫星,他们一定会让你接收到 |
