As a technical member of the JPEG2000 body, I have to say that sitting in and participating in the meetings was quite an interesting experience. As always, there were a number of technical issues to resolve, but the most heated and often most time was spent on IP issues. The comment in the article, warning about people holding IP crawling out of the woodwork if the standard is successful is definitely one to watch. While I have not been involved in the last couple of meetings, I'm still actively involved in following what has been happening technology wise. The benefit of wavelet compression is not so much in compression quality, but in features. From a file, one can get multiple resolutions, multiple quality levels, selective decoding of a specific region (random access), etc. This should be a benefit in the long run. The article touches on it briefly, but one down side to the new standard is that it is more resoure intensive than the current JPEG even PNG formats -- in memory and cpu power. I suspect it will be a while until we see wireless devices with the resources to handle the format in a general purpose manner. A custom ASIC solution is a possibility, but would a device like a Palm Pilot include one? What are the factors that lead to the improved quality and additional complexity? JPEG2000 is based upon wavelet compression. The standard allows for tiling images, but it is more typical that the whole image is compressed, for most applications. Unlike JPEG, where pixels are grouped into 8x8 blocks, wavelet schemes which operate upon the whole image have a lot more data to play with when it comes to throwing away (quantizing) information. If one were to attempt to use the standard with 8x8 tiles, well, it would not work very well. Because of this increase in data that is part of the working set, the amount of memory needed, when compared with JPEG is, in most cases, much greater. During the JPEG2000 process, a few companies proposed block-based wavelet solutions which would reduce this complexity without sacrificing feature set or even quality. However, they were not included due to concerns over the companies not making the IP available on a free and non-discriminatory basis. There has been a part-2 to JPEG2000 proposed that will allow for the inclusion of technologies which IP is not necessarily free. My question to the group here is, if JPEG2000 takes off and companies and individuals who have not previously declared IP come forward and want royalties, will the standard be hurt? Is there a place for a part-2 which contains IP which is not free? And, what applications does the community here see as being crucial for the adoption of JPEG2000? --martin
Can you say "prior art"? I thought you could. Lets look at the abstract for this patent, dated, oh, from 1996: A local host computing system, a remote host computing system as connected by a network, and service functionalities Telnet, telnetd, and the DARPA ARPANet, circa 1981. a human interface service functionality, That would be the telnet client a starter service functionality, The negotitation that happens at the beginning of telnet session to determine your terminal type and a desired utility service functionality, Such as remote access to the UNIX or VMS commands on that other machine on the DARPA ARPANet and a Client-Server-Service (CSS) model is imposed on each service functionality. Telnet won't much work if without a telnet client, a telnetd server, and both being compatible with the appropriate RFCs. Come to think of it, I think the RFCs would be the place to find prior art.
Will they push for new laws that would force copyrighted content to be censored at the border (in the router), like other countries such as China do in their firewalls?
Does it come in 0.3mm? I write very small and I find I can put 60% more numbers on a single page before I have to break my concentration to get another page.
I'm getting really tired of people who think that laws which originated hundreds of years ago are still completely applicable today. While on the one hand I agree that too many new laws make things too complex for simple folks, the fact of the matter is that we need more laws because there are more people. Not that I like these laws, but we have to learn to live with them, just like we have to learn to get along with each other.

What if you get caught out in the rain, or worse yet a thunderstorm?
Not to mention that these things are so small its very likely that if you strayed into the wrong airspace a larger aircraft wouldn't see you until you wound up on their windshield! (ouch)

Last post!
Sorry, couldn't resist...

OOG is a prophet! He hath fortold the drop in stock prices only two weeks before Dow drops 5% and NASDAQ 10% in one day.
WHO THINK IT FUNNY THAT OOG THINK THAT BEST PERSON TO GIVE GRAMMAR LESSON IS OOG?

Might I suggest... Star Trek: OOG! Not any worse than TNG, DS9, or VGER ;-)

Do it yourself and save.

There is a fine line between a mad troll and a comedic genius. Oog has erased that line.
Why don't you pour a bowl of hot minix down your I/O channels instead? :-)
