What is the difference between “HD-ready” and “HD-capable” TVs?
Today’s HDTV sets come in two forms: HD-ready and HD-capable. HD-ready sets have an HDTV receiver/decoder built-in, while HD-capable sets simply act as a monitor and require the addition of an external receiver/decoder to receive high-definition signals. Since most HD-ready sets only include receivers for off-air broadcasts (i.e., signals that are received using an antenna), you will still need a separate HDTV receiver to view HDTV programs with Cox High Definition Cable.
