Digital TV adapter

IF the purpose of a digital TV adapter is to convert the signal from Digital to analog so that older analog TVs 

can still be used, is it possible that an all Digital TV would eliminate the need the adapter in the first place?

They are also descramblers, so a box is required on every TV.

Yes, that's how it used to be. Basic channels were not encrypted allowing any customer with a digital tuner the ability to just hook up their TV and get at least some service. This was fantastic as you could have an extra outlet w/o additional cost.  Becuase cable is a closed radio (RF) system -all content is broadcast to all devices - Comcast switched to full encryption to prevent theft and the need to physically disconnect/reconnect services. And of course to increase profits.

Thanks   nerdburg

I think I understand it now.

I will still need the DTA's for extra TV's .

And this is because of the encryption.

And encryption prevented piracy and increased revenue at the same time.
