Tim's right on suggesting not to rule anything out. I have a big Yamaha 
RX, 10-15 years old, that routes audio and video through it in several 
formats. When I installed it, I choked cables to speakers and antennas 
before turning it on. All those interconnect cables are possible 
antennas for Pin One.

Another point -- in the world of consumer products, the word "digital" 
is very much a marketing term. For example, digital antennas. :) In the 
case of a TV, the only technically correct use of the word is that the 
RF tuner and demodulator for digital signals and some logic to support 
those signals, is built-in, rather than an exterior box. My 10-15 year 
old Sony had such a tuner for first generation digital TV standards 
built in.

A new digital TV Standard (NTSC 3.0 I think it's called) was introduced 
maybe 5 years ago, and is being pretty widely adopted major markets. It 
has many interesting capabilities, including the ability to transmit 
pay-TV, in which the decoders are connected to the internet and make 
extractions from our bank account. Current generation TV sets will have 
a new generation tuner built in, and some are better than others. There 
are also several outboard tuners that that feed audio/video inputs of 
existing sets.
