There are many different kinds of compression. Lossless compression involves throwing away the stuff that is redundant and is indistinguishable form the original. However lossy compression involves throwing away actual data which can affect the output quality. I was involved in a bunch of testing with CBC and BBC back in the 80s where user perception was measured against the amount of lossy compression. At some point it becomes obvious to everyone, but most people dont perceive a moderate amount of lossy compression.
