9月1日加拿大电视信号转成数字信号(Digital) (~=高清电视信号)，没有模拟台(Analog)了。应该很多人一个台都收不到了.

“高清天线”这种东西, 只是一个市场概念。数字信号(高清电视信号)是用 UHF band （旧天线的圆形部分）。旧天线可以继续使用。

只是不同的天线接收性能不一样，听说最好的天线是 Channel Master。

自己做的天线效果不错，比大多数商店买的天线好 == http://www.sinoquebec.com/bbs/showthread.php?614363

旧电视 (传统的CRT电视和旧的液晶电视) 是使用 NTSC Tuner, 数字信号/高清电视信号用 ATSC Tuner. 需要买新的电视机或购买数字转换器(DIGITAL CONVERTER BOX)。部分电视有NTSC 和 ATSC Tuner, 只需要从新扫描一下频道就可以了。

From : http://www.ehow.com/about_629815 ... mp_-atsc-tuner.html
A tuner converts over-the-air (OTA) radio frequency transmissions into audio and video signals used by receiving devices to create picture and sound. NTSC (National Television System Committee) and ATSC (Advanced Television Systems Committee) are two standards for television transmission that require separate tuners. NTSC is an analog standard that has been in place since 1941, and ATSC is a digital standard adopted in 1995.

如果你付款用Videotron 的基本有线电视(模拟信号)，你仍然可以使用你的旧电视。或使用你的旧电视看DVD/录像机。或使用你的旧电视玩游戏。
