Status of s3tc patent in respect to open-source drivers and workarounds
Hi radeonhd, nouveau, mesa3d developers,
Firstly, thank you all very much for all the important work you do.
I've been working as a part-time developer on the "Spring RTS" project
(open-source game engine) which runs on linux (and other os). Some time
ago I tried the engine on the open-source ATI radeonhd driver, which I
understand to be partly based on mesa 3d, and all textures

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?

Sprint Nextel sueing over VoIP patents
Sprint Nextel is sueing vonage, voiceglo and theglobe.com for infringing
on VoIP patents. Sprint Nextel claims to have about 100 patents on VoIP
technologies. Does anyone know which ones this article is talking
about, and if so does asterisk have any of those features?
The reason I am asking is that the article is vague, Vonage uses a
fairly standard codec set, I dont know about the others.

Theora patent question
Does the reason Theora is relatively safe from patent infringement
lawsuit have more to do with it actually not being encumbered, or is
it because its use is decentralized?
For example, FreeType is not patent-free, nor is Linux, yet they
succeed because on the one hand, they are open source, and those who
maintain them do not guarantee anything regarding patents, it is up to
each individual user

Patent troubles...
Hi everyone.
Reading all this posts about patent issues, I thought of something:
if, by some wild chance FhG (or some other audio company) manages
to prove in court that vorbis is breaking their patent rights, you could
do something like LAME developers did: release only source code and
let people do the compiling so that only users that are living in countries
where patents on algorithms are

That is not necessarily where the majority of patent lawsuit *danger* comes

Fruanhofer patents and royalties for Streaming
Everyone involved in the Vorbis project should get their A into G and
get streaming worked out before the 1st of Jan, so that when Fruanhofer
start cracking down on streaming MP3, there's a good, workable
alternative to switch to :)
This includes the plugins and such

patent issues with Vorbis
Hi,
We are in the business of developing/productizing Multimedia codecs for embedded systems. Recently, Vorbis has gained good popularity. We are also developing it.
But we face few problems related to patents. Vorbis claims to be patent free. Is there any particular search made for possible patent infringements and corresponding report published? We need to convince our customers sometime

[OT] Just saying hi!
I hope this list is small enough for not beeing banned when
introducing oneself. So...
Hi,
I just subscribed to the theora-lists. I'm from the XVID project,
so I know a deal about video and MPEG-4 in particular, but nothing about
Vorbis/Theora etc., That's why I'm here, because I'm interested in
patent-free alternatives.
I guess there is no documentation of the current status

troll or truth ?
Hello,
I was discussing on the mplayer/mencoder ML about transcodingfrom Divx
to Theora. I got these kind of answers:
http://article.gmane.org/gmane.comp.video.mencoder.user/280
Of course I understoud only 50% of what he said, as well as I am not
really used with codec and video glossary...
But I generally understoud his opinion. What to think? I would like not
to believe him, espacially when

Fraunhoffer claims patents on other formats
Here in the uk, to get a patent on anything, you have
to prove that the patent is not obvious and that there
is no prior art.
If there is prior art, then a patent cannot be given,
this is why people patenting stuff have to keep it a
secret until they actually have the patent, otherwise
it is considered to have been released into the public
domain.
Once something is in the public domain, nobody

Independent implementations?
Hullo,
When people ask me what Vorbis's license terms are, I usually tell
them that the bitstream format is in the public domain, that the
reference libraries are licensed under a BSD-like license, and that
the example programs are licensed under the GNU GPL. (Note the
distinction between filespec and implementation here.)
Meanwhile, Theora.org's FAQ doesn't say anything about the

Verizon Vonage 101
I've dug down as far as I could on www.uspto.gov for
anything remotely close to what is going on with
Verizon and all searches end with only two
possibilities in regards to what is going on.
So unless the patent was issued to someone else and
Verizon bought it, these are the only two possible
patents this case could be based on...

Steve Jobs about theora
I guess you've all read it already, but here it goes:
"All video codecs are covered by patents. A patent pool is being
assembled to go after Theora and other ?open source? codecs now.
Unfortunately, just because something is open source, it doesn?t mean
or guarantee that it doesn?t infringe on others patents. An open
standard is different from being royalty free or open source.

Blocking and compression.
I did some research on patent claims on range and arithmetic coding. The
original range code pdf presented in the UK by an ibm employee at the
time asserts no patent claims what so ever. If there are patents I cant
find em. I have the original paper in PDF if anyone cares to see it. Its
a good candidate for encoding because browsing a few of the
implememntations avaialable on line, I can roll my
