This post: http://www.avsforum.com/avs-vb/showthread.php?p=14452591#post14452591 claims this HDMI cable can fix corrupted data.

This is pure BS and the FTC (yes FTC, not FCC) needs to jump on this. It's false advertising. No cable can correct corrupted data. The only way to correct corrupted is by use of checksums, CRC, FEC, or other sophisicated error correction algorithms. These schemes not only chew up bandwidth, they often take extended processing time.

Now the best any cable could do is have a built in active equalizer. As HMDI carries power this is possible. But that is not "fixing corrupted data" it would merely sharpen the risetimes to where perhaps the receiver could recover the bit. If the cable is just ultra low capacitance, that's good. But it won't correct anything in the data stream. It will not cause further degradation but again that's not the same as claiming it "fixes data".

I am so tired of the claims that the more money you spend on a digital cable, the better the audio/video quality. If the sound / image is glitch free then you are getting all you can get. It's just that simple. Corrupted data causes hits and glitches, not soft images, muffeled sound, desaturated colors, etc. The data is either good or it's not.

To be fair, I think you're exaggerating the nature of the claims made in the article a bit, and it becomes something of a semantic issue. If the cable is EQing, it is, in effect, correcting the data stream. You seem to have interpreted the article as saying that the cable corrects or alters data WITHIN the stream. So it can certainly improve, and thus 'fix' the signal, now whether you want to characterize that as 'fixing data' or not seems to be a fairly subtle distinction. It's a perfectly fair one to make, but I don't think this is the kind of claim to get worked up about.

Honeywell's actual characterizations don't mention improving the picture in terms of making it better if it's working properly. All of their examples involve snow, severely degraded images, intermittent images, or no picture at all.

Sure. But I think you're attributing these kinds of claims here where they aren't being made this way.
