PlusV algorithm
Important (imho)!
I found this site in the internet:
http://www.plusv.org/
PlusV is an audio enhancement algorithm similar to SRB of Mp3Pro, but
1) better than SBR
2) Fully open-source
It seems to me wise to include PlusV into new versions of Ogg Vorbis.
P.S. what about some long-awaited features in Ogg Vorbis?
1) ability to turn off the frequency filter in the encoder (especially for high

Hi,
I haven't seen this mentioned here before.

"With traditional MP3, a typical Near CD Quality audio file has been
encoded with a data rate of 128 kbits/s. While this is ok for people
with big hard disks and fast Internet connections, this data speed

More [A tangent on RC5] Cryptography patents (was: openssl lib question.)
I hate following up to myself, but
I thought a clarification of one

might be worthwhile...because what
I should have said originally was
that "To the best of my non-legally-

Patent issues, what features we can't use?
Hi everybody,
As the Asterisk community is getting larger and larger, I was wondering that
the features which are provided in Asterisk and are programmed by the open
source community under GPL, or GUIs like FreePBX which also come loaded with
wonderful features and uses same Asterisk, are they anywhere violating any
patent laws? Most of the features work the same way as Nortel, Avaya and

Cryptography patents (was: openssl lib question.)
Sunil--
Actually, you do not "see that openssl
has some patent issues." You do see that
OpenSSL implements many algorithms, some
of which have been (at various times)
been patented or encumbered in some
countries.
Without knowing what country you're in,
none of us here can really give useful advice
as to which software/algorithm patents
could potentially apply. To the best

Mutually assured minefields.
The specific standards process used to develop the MPEG codecs
creates patent minefields that royalty-free codecs don't generally
face. Because many knowledgeable people have heard of the problems
faced by these patent-soup standards, they may extrapolate these risk
to codecs developed under a different process where these problems
are less considerable. This is a mistake, and I'll explain

patents and separate entropy coding
Hi everyone,
first of all, I searched through the archives for any posts resembling
this, I didn't read all posts about the patents so if this has been
suggested before I apologise.
I read in an article on C|Net (I think, it was linked from Slashdot
anyway) that Thompson are threatening to sue you if Ogg Vorbis becomes a
success. Which is evil, and I'm also mad at them because they never

NHW Image codec
Hello,
So here is the compression scheme that I don't know if is covered by patent.
I use it on the wavelet DC parts.It outputs 1 byte (8 bits) words.There is
5 modes:
- 1(MSB) | 7 bits to store value (0->127 range)
- 01 | 6 bits to store val[n+1]-val[n] | val[n]-val[n-1] if each in the
range [-4,4]
- 001 | 5 bits to store val[n+2]-val[n+1] | val[n+1]-val[n] |

That is not necessarily where the majority of patent lawsuit *danger* comes
from, and i'd argue, pretty strongly, it's not the most likely case for

Patenting a mathematical formula is NOT creating a machine nor is it unique. For example. 2+2=4... apples + apples^2= given outcome. I want to patent this. It's stupid to patent something like that. The same is true for formula algorithms. Algorithms occur in nature. Thus should not be patented. Now, Volley G Mathison inventor of the Electropsychometer had a machine that he could patent. A

NHW Image codec
Hello,
Ok, and that's too many work to review a source code.In my codec, I have 3
compression schemes, I think 2 are not patented, but the third... I don't
know.For the rest, I think my codec is patent-free (I don't use
SPIHT,EZW,zerotree methods), even the wavelet transform is new and don't
use the lifting scheme nor the convolution product.
Else, if you found time to review the

Theora and software patents
The list probably did not get this reply from D Richard Felker III.
Having read quite a few patents I tend to agree with Richard: Software
patents are very broad and even if I have not read the source code of
Theora I would be surprised if it did not infringe several patents.
However, I believe the argument that On2 has not been sued for infringing
the MPEG-patents is a very strong argument.

DV format patent status
Hi folks,
I was curious what's known about the patent situation with the DV
format. Google turns up a number of press articles describing it as an
"open standard with no associated licensing fees" but also, for example,
US Patent number 5,691,81 which, while I've not done a careful
comparison of the claims, sounds like it covers the block-rearrangement
scheme that's the

Patent situation of Vorbis?
Just a question about the state of Vorbis, if I build an application using
Ogg is there a chance anyone sue me to death due to some stupid patent
violation. Is the method used in the Vorbis compression, decompression and
streams free of any patent violations?

H.264 *Not Patented*
The H.264 codec patent by Qualcomm has been ruled invalid by a San
Diego Federal jury:
http://www.eetimes.com/news/semi/showArticle.jhtml?articleID=197001066 .
That means that H.264 codecs can now be written, distributed and revised

domain, or any other, and $free now that royalties are no longer

Patents
I suppose it could be possible to patent something and
let the patent expire so that it is registered at the
patent office but not enforcable. No one else could
patent it then.
I get curious about the RLE patent. I heard Someone
has a patent on run length encoding and I wonder how
long they have had it because I remember RLE code
