Most major brand flat screen TVs manufactured after 2006 support both ATSC (Advanced Television Systems Committee) and QAM (quadrature amplitude modulation) digital tuners. ATSC is used to receive digital channels over the air. QAM is used to receive digital channels from a cabe TV provider without use of a cable box.
"Support" really isn't the right word.
All TVs manufactured after 2006 must have ATSC tuners built in. However, QAM tuners are optional. Many cheap RV TVs don't have QAM tuners.
If you find that this is the problem (no QAM tuner), then get one of these.
