Question Question accuracy of article

There are 74 different devices that are being sold as HD but are not HD-ready, according to Alexander Oudendijk, senior vice president of marketing for satellite giant Astra.

They may be fantastic quality TVs, but many do not have adaptors in them - called DVI or HDMI (High-Definition Multimedia Interface) connectors - which let the set handle the higher resolution digital images.


Is this correct? I realize Component Cables are not as good as DVI and HDMI, but is it not Hi-Def just because you have CC's ?

And that 1.3% figure seems more than a little bit suspect to me. Does this mean that 98.7% of the Flat Panels in the UK are EDTV?

Many people mention that lack of information about HDTV is a problem in getting everyone "digital and HD", but I think articles that contain misinformation are an even bigger problem because they CONFUSE the very people we're trying to win over to the HD side.

Thanks for the article though. It was interesting to see that Europe appears to be BEHIND the U.S. in converting to HD (if that's correct).

No, he may have given a little extra information. He should have just said they don't have HDMI or DVI connections. These are better since you don't convert digital to analog and back an extra time. Component cables are analog and most definitely provide an HD picture, digital is just better. One would not want to buy an HDTV today without HDMI as that is the way all associated equipment is moving, i.e. receivers, high definition DVD players, cable boxes, etc.

And what would be your anal ysis of that 1.3% figure? Is there any possible way that could be correct? That has got to be a misprint, or else I'm misunderstanding something.

Also, if someone has CableCard, does that mean they would not use HDMI unless they switched to a satellite service?

Don't have a clue about the 1.3% figure.

As far as the cablecard, that just gets rid of the cable box. You still have a high defintion DVD player and/or receiver and anything else you might hook up to the tv that could not go through the receiver. The higher end Denon receivers already have HDMI connetions. In other words you would not want to buy a television that does not have HDMI. You might not use it right away but a couple of years down the road you will be using it since it will improve the picture quality. As you know HDMI includes both the video and audio while DVI is only video.

HDMI is convenient, but it's "advantage" is that it is copy protected, so content producers can control your ability to make copies. Improved PQ compared to component is minimal at best.

Yes, CatMan, using CableCard (or OTA) means you don't need to use ANY video inputs, just the coax input for RF.

If you had no video inputs how would you watch your DVD player? Or how do you watch a D-VHS tape? So you do need video inputs unless you want to restrict yourself to cable only or OTA viewing for the life of the television.

CatManDoo was talking about broadcasts... you would need video inputs for other sources, including Sat, but it's interesting the two examples you give don't require copy protected inputs.

Yes, that is correct. I was wondering about connections for broadcasts. I have cable now and I plan to keep it, but I want to make sure my next TV has Cable Card to get rid of the STB. Right now I have Cable from the wall to the STB, with a DVI line to my TV from the STB, and audio cables from the STB to a Denon 6.1 receiver (I don't use the middle-rear channel; just the 5.1 with 2 fronts, 1 center, 2 backs, and a sub). I'm at work now and can't remember if it has HDMI, but I doubt it because it's not high-end (just a starter unit). So if my next TV has CableCard and I go straight to the TV, would I then run audio from the TV to my receiver to keep the Dolby 5.1 or use a splitter? How would that work, with cables or HDMI ?

Thanks!

HDTVs with tuners usually have both analog & digital audio out... I haven't seen one yet that handles true surround, just 'Virtual' with two speakers, so the TV delegates the SS decoding to an external amp.

You mention running 'cables' from your STB to your SS Amp... depends on the STB, but you usually only need to run ONE SPDIF digital audio cable... true surround can ONLY be carried on a digital connection, analog stereo can only carry ProLogic psuedosurround... some boxes won't convert your analog channels to digital though, so you've got to run a stereo pair as well...

Since HDMI provides digital audio the TV can't fully decode, it should pass it out the digital audio out to the amp... but I've heard some TVs don't handle it properly... and only output from their tuner. Theoretically, your TV should pass any audio it gets...

A number of people wanting to use the HDMI out on their cable box are having to use the digital audio out from the cable box to their receiver and bypass the TV as many HDTVs have no digital turner. As I understand it you can still use the HDMI for video only.

Sure, whatever works... was just complaining about what I consider a design oversight. Passing thru the TV also gives it a chance to add audio delay when needed to compensate for video processing time... hopefully this will be better addressed in the latest models with tuners.

Thanks, you are correct. I'm at home now and I just checked my connections. I have a Motorola box. I think it's a 6200. There is a single "cable" going from the STB to the receiver, and it is very clearly marked "Optical SPDIF". I knew I had true surround because I've heard very distinctly different sounds out of each speaker when listening to a Dolby 5.1 broadcast.

But if I may get back to the "CableCard" issue, I guess my question posed in another manner is: How do you hook up a receiver if you use a CableCard? Sorry, I don't mean to seem so stupid. But if the cable goes straight from the wall to the TV when you use CableCard, how does the receiver fit into the equation? As you mentioned, I have a line from the STB to my receiver now which carries my 5.1 audio. So if you get rid of the STB when you use CableCard, how do you get the audio to the receiver? Would you then have to run a line from the TV's audio output to the input on your receiver? Thanks for your patience and insight.

Yep, you've got it... TV's digital audio out.

The CableCard effectively replaces the STB. The cable feeds right into the set with the ATSC tuner, and the set then decodes the encrypted signals. The current CableCards are only 1-way, so you can't have VOD, however the next release of the CableCards are said to be 2-way, but the set has to be able to accept it.

On a set with CableCard, you eliminate 1 extra step of decoding and the picture is a little better, because you are not inputing the signal via HDMI/DVI or component inputs.

The 5.1 audio is part of the cable or OTA signal.
