"Lossy" - if you are watching at home, it is lossy (Score 2, Informative)

I would not consider myself an expert, but this is my field, so let me give everyone a REALLY quick lesson in 1) JPEG2000 and 2) "lossy" video compression.

JPEG2000 is an advanced set of tools for video compression. It is used at the highest levels of distribution, and has been proposed for consumer use as is the case here. For more on JPEG2000 a decent primer is here.

If you are watching content at home, it already has gone through a "lossy" compression scheme. Whether it is DTH satellite MPEG2 or MPEG4), cable (MPEG2/NTSC - yes NTSC is a lossy compression scheme), or terrestrial (MPEG2 ATSC or NTSC), DVD (MPEG2), or even LaserDisc (NTSC), your content has gone through a lossy scheme.

Remember, Google is your friend, and although not perfect, wikipedia can answer many questions. For more on video compression here is a nice little presentation.

The short story is everyone shouldn't get real upset about JPEG2000 and it being lossy. Cheers.
