I have some questions about this, so feel free to blast away at anything that I say. I have a feeling that some people think they are receiving digital cable, but are not.
The 'top of the line' for this would be to have a cable box with a DVI(-D) output that feeds into an HDTV at 1080i. You would have a digital signal from start to finish.
If the cable box only has component outputs (at best), is the digital HD signal in the cable box converted to analog before it goes to the component cables that go to the TV? This would be one step down from the 'top of the line', and still be 'HD', but not 100% digital.
If you did not have an HDTV, (even if you do get a better picture with 'digital cable'), it would only be 480i at best. With that, using an S-video cable or even a composite cable wouldn't be as good as component, but close. (We can skip the discussion on comparing picture quality by moving up from composite to s-video, etc).
Back to square one. I know how screwed up advertising can get, but any cable box that did not have a working dvi output can't legally state that a user can receive a digital signal on their TV. (Yes, I know that they have this worded to avoid lawsuits).
So, could a digital cable box that only had component (at best) outputs really be a digital cable box? If that were true, could you demand the digital cable box at the price of an analog one because they didn't have the proper outputs? What if your only TV had one input - a DVI-D?
(Advanced section, just for the sick & twisted!) Unscrew the back panel plate on your TV, where all of the sockets are. Carefully tape it inside, and then get a blank plate, cut out a slot for a DVI connector, and set it in place. If the cable installer didn't have a CATV box with a working DVI output with him, he'd be screwed!
(Admins - I put this in TV because it does not refer to any specific piece of hardware, but rather, just the signal itself).
So, in how many places did I screw up?
