You could apply for a patent on something you read, but (a) you're
required by law to disclose any prior art, and (b) the original
inventor can also apply for the patent, or if he/she/it chooses not
to, he/she/it could later demonstrate their own work as prior art.

It is the case that U.S. patent law dictates the inventor must apply
for a patent within a year of the first published work.  That includes
using the code in a public package, publically available information
(i.e.  internal or confidential documents don't count), etc.

I'm not a lawyer, but I went through this all a year or so ago when
helping fight a stupid software patent.

I am looking for references or folks working in the area of video
compression.  Who's doing it? Is there other techniques besides
MPEG being looked into, like wavelets? What level of compression
is acheivable in terms of bits/pixel?  Thanks in advance.

is Lharc, which uses the -lh1- method, where Lha uses -lh5-.  Lha is compatible

REARJ will work well except for preserving internal

Meybe, but the warning is there. Some motherboards seem to give problems
and I also noticed some strange CRC errors with really large archives.
Don't forget it is just an alpha version which should according to
PKWARE not be used except for testing. Also notice ZIP 1.9 is compatible
and does NOT have an alpha status. It's free too.

Even PKZIP 1.10 seems to be dangerous BTW, see the file I posted 2 days
ago and the fix I posted 1 day ago. A program existing for so much
time which can not compress some files properly migth be called
dangerously.

There is a program called XCHANGE which will convert any archive format
into any other archive format. This includes archive of dissimilar types
within archives (i.e. and ARC file inside a ZOO - all to be converted to
ZIP).  It's basically a shell program that uses a simple parameter file
to expand and compress each archive format.  I have used it  for about
3 years now with no problems and easily add new formats as they appear.

If you cann't find it locally let me know and I will see if I can mail
it out.

I would bet that Ross Williams worked on LZRW3 for MORE than ONE YEAR

Date: 1 Oct 92 13:51:45 GMT
Reply-To: pullin@mail.physics.utah.edu
Organization: University of Utah, Department of Physics

Hello

I compress a text file in my unix workstation (IBM RS6000 AIX 3.2, standard
compress command generating a .Z file), transfer it by Kermit (binary mode)
to my PC, where I decompress it with comp430.

It happens that the CR-LF (or whatever makes a line of text finish and go to
a new line) in the original file get replaced by something else (maybe a CR
alone?, it appears in my editor as a little square). In summary, my text
file appears all in a single line.

Is this a usual problem, or is it due to the particular combination of 
compressor/transmitter/decompressor used?

Please reply by email, I can summarize if there is interest.

Thanks in advance.
Regards.

i need a fast compression/uncompression program, preferably one that
works on a Convex (basically BSD Unix with vectorization) and that
vectorizes well.

I am well aware that all adaptive encodings (Lempel-Ziv, Huffman)
will not vectorize well, since adaptiveness is somewhat contrary to the
concept of vectorization.

Background: Our Convex has a couple of filesystems that are about 2.2 Gb
in size (Convex has modified the berkeley filesystem). We do our
backups over the network to to a sun with a 5 Gb Exabyte. It appears
that the Sun SCSI driver just gives up after reading more than 2 Gb in
a single file.

The bug is in PKZIP, for one simple reason: zip 1.0 implodes
the same file, and it then explodes well with both unzip and
pkunzip. PKZIP can't implode the file. So the problem is not
the algorythm, and it is not the decompression. It is the
PKZIP code.

BTW, very interesting bug. Looks like a buffer overflow to me.

There goes. Note that i use extension "z10" for zip 1.0, and
"zol" for zoo low density. This is necessary only when
converting TO these formats, because of the way rearj works.
Just rename them after the conversion.

Note also that rearj is free only for ARJ users, according
to the author.

Hello

Forgive me if this is a FAQ, I couldn't find any references to it in the

I compress a file in my unix workstation (IBM RS6000 AIX 3.2, standard

Is this a common problem of compressors or just a pathology of the

	I tried ARJ 2.39 for a while.  Looks like a beta-test version of an 
incoming new ARJ utility.  When I uncompressed it, I got a full-screen 
warning that it is a beta-test, do not use it for everyday use, use it for 
testing only and report bugs.

Yes, Ketan, you are correct.  Anyone who believes that XING MPEG data
is representative of the compression ratios and quality available from
the MPEG standard is being sorely misled--though I do understand why
XING has chosen their implementation: complying to the full standard
requires more than software running on a PC.

  How does one use the tarread for MS-DOS.  I tried looking for some help docs
put I could not find any.  If anyone can give a brif decripsion on how to use
tarread or and point me to a help file on it, would be most exceptible.  Thanks
in advance.
