Older TV’s receive and process an analog signal to display a TV program. Newer TVs receive digital data and convert it into a TV program… much like your computer makes an image on your monitor… That’s digital TV (DTV). DTV can be either standard definition (SDTV) or high definition TV (HDTV).
Unless the government delays the transition again, in June 2009 all TV broadcasters will switch off their analog transmitters and broadcast only DTV. While a lot of programming will be HDTV, for at least the next few years most programming will be in SDTV.
You will still be able to use the old TV in your RV along with your RV’s TV antenna but you’ll need a converter box.
Many TV broadcasters are already broadcasting DTV and RVers are finding they can’t receive TV signals at their favorite campsite even though the could before DTV.
Like all things digital, DTV is all or nothing. As such, if you have a strong enough signal you will have a great picture but if the signal drops, the receiver will loose the digital information needed to make the picture so the screen will freeze or go blank. No more watching a TV program through the snow like we did with weak analog signals.
