Good Signal Quality = Good Picture Quality?

"There is basically no correlation between signal quality and picture quality, until you get to the point of picture loss. As in, a decrease in signal quality does not have a corresponding decrease in picture quality. This is a common misconception."

Is this true? :wall

I am from Jalandhar, Punjab. My Videocon D2H HD gives:

65% Signal Quality in HD channels
75% Signal Quality in SD channels

I was using TataSky HD from last over 2 years and the picture quality was much better than Videocon HD. Signal quality was also like 80-90% on TS.

- What is your signal quality on Videocon?
- How do you compare Videocon HD picture quality with TataSky HD?

do you find pixellation if yes there might be a small alignment problem or due to a faulty lnb

There is no pixelation. Its just that the picture quality looks 25% compressed than TataSky HD channels. TataSkyHD channels were crystal clear. VideoconHD channels look poor in comparison. :-/

If signal quality/ strength is less, pixellation will increase and audio starts breaking/popping. Picture quality as such is not affected in Digital signals. Direct relationship to signal level is applicable in Analog signals, where you see snowy picture if signal is weak.

Yes, this is correct. Videocon service engineer said the same thing.

I got my signal quality increased from 65% to 80% but it did no make any difference to Picture quality. TataSkyHD has better picture quality than VideoconHD. :angry
