Why is the picture quality of an analog cable source so crummy on my Sony Bravia HDTV?

Question

Of course I understood when I bought it that the picture quality would still only be comparable to that of an analog source, because I'm not able to get a digital signal where I live (I just like the fact that it's big, bright, attractive and takes up so little room.) But honestly, the picture quality is FAR INFERIOR to the quality I got on my tube TV. Anyone else experience this? Does it have something to do with the widescreen aspect ratio? Help!

Answer 1

It's all about native resolution and scaling. For video, the larger descrepancy between video resolution and native tv resolution, the more video artifacts and degradation you will see.

Standard analog cable is 640x480 or 480i resolution. Expand that to 1280x720 or 1920x1080, that is alot of ground for a scaler to fill in. That is why standard def video looks bad on a HDTV and loosk good on a tube TV. Tube TV has native resolution of 640x480, therefore there is no scaling involved when watching regular tv. The fact it is analog, that will only magnify all the noise in the picture by viewing it on an HDTV.

Going to digital will help a little, but going to HD stations is the only way to get the best quality. I always advise people to stick with tube tvs, if they don't plan on going HD.

Does that make sense?

Answer 2

The scaling argument would apply to both analog and digital standard definition, since both are scaled up from 480i to the set's native resolution. Yet standard definition digital television looks great on a HDTV set. The real reason is that the higher quality picture on the HDTV will reveal all the defects in the analog picture that are obscured on the lower-resolution tube TV, Even analog cable, which should be a low-noise, clear picture, is often quite poor and snowy. If you don't have digital TV available yet, try looking at a good quality DVD, using a DVD player with progressive scan (480p) output and component cables. You should get an excellent picture (but not as good as real HDTV broadcast).

The reality is that your HDTV picks up the impurities in the SD signal while your tube did not. More than likely your cable / satelite box is not properly grounded and your not using a power line conditioner. Get a Jensen ground Isolator and get a power line condition from Pure|Av or Monster.
