There is a difference! To make it EZ to understand, if your HDTV set does not have a digital tuner*, it will probably be labeled "HDTV-Ready."
*A digital (ATSC) tuner receives the digital signal (which includes high-definition), and allows the television to display digital programming.
HDTV-Ready means that your TV set is capable of displaying analog and high-definition (HD) digital pictures, but without a digital tuner, it cannot receive the digital signal.
An HDTV-Ready requires an external high-definition TV receiver (digital tuner) in order to receive HDTV signals. These external receivers can be called an HDTV Tuner, set-top-box, or DTV Converter Box.
If you have an HDTV with a built-in digital (ATSC) tuner (which manufactures must include after March 1, 2007), your set will internally receive and display analog and digital signals without an external receiver. This applies to cable, satellite and over-the air broadcasts.
