Sony BDP-S280 - Manual (Page 65)

LIABILITY for damages of any kind.
These conditions apply to any software derived from or
based on the IJG code, not just to the unmodified
library. If you use our work, you ought to acknowledge
us.
Permission is NOT granted for the use of any IJG
author's name or company name in advertising or
publicity relating to this software or products derived
from it. This software may be referred to only as "the
Independent JPEG Group's software".
We specifically permit and encourage the use of this
software as the basis of commercial products, provided
that all warranty or liability claims are assumed by the
product vendor.
ansi2knr.c is included in this distribution by permission
of L. Peter Deutsch, sole proprietor of its copyright
holder, Aladdin Enterprises of Menlo Park, CA.
ansi2knr.c is NOT covered by the above copyright and
conditions, but instead by the usual distribution terms
of the Free Software Foundation; principally, that you
must include source code if you redistribute it. (See the
file ansi2knr.c for full details.) However, since
ansi2knr.c is not needed as part of any program
generated from the IJG code, this does not limit you
more than the foregoing paragraphs do.
The Unix configuration script "configure" was
produced with GNU Autoconf. It is copyright by the
Free Software Foundation but is freely distributable.
The same holds for its supporting scripts (config.guess,
config.sub, ltconfig, ltmain.sh). Another support script,
install-sh, is copyright by M.I.T. but is also freely
distributable.
It appears that the arithmetic coding option of the JPEG
spec is covered by patents owned by IBM, AT&T, and
Mitsubishi. Hence arithmetic coding cannot legally be
used without obtaining one or more licenses. For this
reason, support for arithmetic coding has been removed
from the free JPEG software. (Since arithmetic coding
provides only a marginal gain over the unpatented
Huffman mode, it is unlikely that very many
implementations will support it.) So far as we are
aware, there are no patent restrictions on the remaining
code.
The IJG distribution formerly included code to read and
write GIF files. To avoid entanglement with the Unisys
