I've heard several 'opinions' as to what is going to happen in 2009 when HD TV broadcasting becomes the norm. An Ad on PBS said that if you're currently on cable or satellite you don't have to worry, but if you have an antenna (rabbit ears) you will need a converter. An aquaintence told me everyone that doesn't have an HD-capable tv will need a converter regardless of source.
So, can someone give me the real 411?
