Q&A
4. Can I connect my DTV set-top receiver to my cable TV service?
Cable TV systems use a different method for transmitting digital TV programs that is current-
ly incompatible with broadcast DTV set-top receivers. So you will still need to use an out-
door or indoor antenna to receive OTA broadcast DTV programs.
The good news is that you won't have to pay a monthly or per-program charge to watch
OTA DTV and HDTV programs. They're free, unlike subscription satellite TV or premium
cable TV. All you need is an antenna and a DTV set-top receiver to enjoy clear, sharp
widescreen images and high-quality audio.
