What is the difference between pixelization and an ingressed signal?

Question

When I play a DVD, I sometimes see a paused picture and the picture breaks up into little blocks like a puzzle or something and then I can't get it to play anymore. Does anybody know what they call this? I heard it's called pixelization but other people say it's an ingressed signal.

Answer 1

pixelation is break up of a digital signal, but on a DVD player this is called an ingressed signal because it is not a transmission you are receiving but a prerecoded media, clean you r discs or shell out for a decent DVD player !

Answer 2

I don't know what an "ingressed" signal is, but the problem you are seeing is probably the result of a defective or dirty DVD. The signal from the DVD has deteriorated to the point that it cannot be decoded by your player. One of the symptoms of a weak signal is "macroblocking" which is the picture breaking into the blocks used to compress it. When the blocks themselves break up into smaller pieces, that is pixellation. However, the two terms are often used interchangeably. If it happens on a particular disc, try cleaning the disc surfaces (you can get disc cleaner kits).

If this happens on all your discs, you may have a defective player, but you might try a "laser lens cleaner" on it.

Answer 3

The DVD signal is "compressed" not ingressed.

You see "macroblocks" (16x16 pixel areas) that the DVD does not know how to display. Your DVD disc is probably damaged (scratches, dirt, etc. ) or very dirty. Try to clean it with a soft cloth.

Answer 4

When someone tells you things and they are using those sorts of words you should ask them what they mean.

Ask them to explain what the word is.

You will often find people use words which they copy from other people without understanding what they mean.

If they don't understand a word, they shouldn't use it.
