There seems to be a lot of confusion about digital TV so I think articles like this one should be required reading by everyone. One of the problems is that a lot of equipment being sold these days is incomplete. The sets don't have all parts necessary for receiving the digital signal. Sure, some of the flat screen displays, especially the plasma ones, look great, but without the digital tuner and/or digital cable box, the signal is still analog. Here the television industry has failed to educate the public on what is needed.
