Tell if a TV Is Digital or Analogue
Due to a national digital crossover in the United States, analogue TVs will soon be a thing of the past. However, many people still own CRT sets and may be unsure of whether or not they'll be able to tune into the new digital broadcasts. Here are a few pointers on determine whether your set is digital or analogue, and tune into digital broadcasts even if you have an analogue TV.
Digital Transition
As of June of 2009, most full-power analogue TV transmissions in the United States were shut down as a result of the nationwide conversion to digital broadcasting.
Size and Shape
If your TV has a flat-panel, widescreen display, it's unlikely that your TV is analogue, even if it has analogue inputs like coaxial cable jacks or RCA or S-Video ports
CRTs
If you own a bulkier set that utilizes a Cathode Ray Tube (CRT), you might have an analogue set. CRT screens use a 4:3 aspect ratio, a more square shape than widescreen TVs that have a 16:9 ratio. Some CRTs do have built-in digital tuners, though.
Read the Manual
Check the owner's manual for your TV for references to a "digital tuner" or "digital receiver," HDMI (High Definition Multimedia Interface), HDTV or ATSC.
Converter Boxes
If you have an analogue TV, you can still watch digital transmissions with a converter box, which you can pick up at almost any electronics store.
