This is the method Cable companies use to modulate digital TV signals. It allows them to deliver multiple programs over a single 6 MHz channel. Due to difference in over-the-air and cable transmission characteristics this is different then broadcast TV.

The guy replaced some of our ancient connectors and splitters. When my husband asked why we would lose just one channel (we are video/networking dummies), the tech (southern accent, so I had a hard time understanding anyway) said something about our connectors causing us to lose a "qualm" that that channel was on, due to lousy connection. It sounded like "qualm."

What is a "qualm?" Is there a term that sounds like that, in fiber/cable wiring terminology?]]> http://www.dslreports.com/forum/remark,19742808 Sat, 05 Jan 2008 09:40:27 EDT
