There's more to Motion JPEG 2000 than just wrapping a bunch of JPEG 2000 files into 1 file.
-timings and support with audio (file format) -description for storing interlace video (odd, even, first, last, etc.) -Color space and sampling (YUV 4:2:2, 4:2:0, etc.) -streaming writes and reads (faster access and writing.) -and more.
Why do people want this for archival? It has to do with preserving the source as closely as possible. Film stock is frame by frame, why should interframe coding be used for archival?
Also, you can seamlessly use the same codec for your image and video archive.
What makes JPEG 2000 stand out from other wavelet based codecs (wavelets have been around for a LONG time and in other standards): -EBCOT a whole bunch of features such as: random codestream access, scalability, network streaming, etc.

It looks like Sony's own Blu-ray recorder will now have some competition.
no. it means that HD-DVD has one less argument against blu-ray. (i.e. sony only format)
notice this is the initial stage for the format war... between blu-ray and HD-DVD. once the next gen format (blu-ray or HD-DVD) has been decided THEN the makers will start competing against each other...
Notice now that for the beta vs. VHS war, it was pretty much sony vs. matsushita(panasonic) but now they are supporting each other. we have come a long way...
each company in the blu-ray camp were showing off LOTS of players last year here in tokyo at the consumer electronics show... while HD-DVD were still just showing mockups... toshiba and NEC better play catchup fast... cuz the race has alrady started.
great way to share info and to keep it centralized on you. runs linux and has built in: SMB, NFS, HTTPd, FTPd, and hell even telnet. you can TELNET into this baby!
beats reaching around to the computer to connect through all that cabling...
now if it could also PULL information...heeheh... >:-)
JPEG2000 is a huge standard. i know, i am actively following it now and was part of the standards process. new parts are still emerging but the core codec work is done.
still, the greatest issue is the patent question... the JPEG patent issue that came up 2 years ago really caused everyone to rethink their JPEG2000 deployment scheme. there is a new project in the ISO group to ensure a baseline license-fee free JPEG2000 codec to ensure the same patent problem won't happen again.
other notes: JPEG2000 won't kill JPEG... ever. digital cameras just made sure of that. all the digital cameras out there record directly to JPEG... no way to upgrade them to JPEG2000.
camera makers still waiting for JPEG2000 chips to be a drop-in replacement for JPEG chips... the biggest hurdle now is power consumption.
initial JPEG2000 cameras will probably also record to JPEG... i.e. backwards compatibility.
JPEG2000 is designed to fix all the problems of JPEG and bring improved functionality. this is more than just a 1-trick pony (i.e. H.264...) with JPEG2000, it has improved on all aspects of JPEG and also: -scalability: read x% of the file, get x% of the image, no need to pull file format tricks or extra redundancies. -error resilience: as the compression level increases, the compressed codestream becomes more fragile. lose 1% of the compressed codestream, expect 10% loss... especially compared with MPEG codecs. JPEG2000 error resiliency is 10x better than MPEG-4 (part1) and probably much better than H.264... -multi-resolution and position based decoding: only want to see 1 part of the image? no problems. only decode that part of the image. -"visually lossless": a single codestream can act as: lossless archive, visually lossless print-ready format, lossy distribution, and thumbnail. no redundancies. no transcoding.
the kakadu library at: http://www.kakadusoftware.com is VERY good. it has a lot of tools you can use right away. check out the KDU_server app.
more things to expect from JPEG2000: -more metadata -better workflow solutions (i.e. capture->process->print->archive) -unified still & motion cameras (i.e. 1codec, 2 applications: stills and movies. thanks to standardized file formats) -true network imaging (i.e. JPIP) -secure images (i.e. JPSEC) and from that, a better imaging business model.
browser plugins: trivial. really. especially if you use the available libraries.
things holding back the standard now: hardware support. there is a lot of software out there but until we get that killer JPEG2000 app, that software will not be touched.
JPEG does a great job, JPEG2000 will do a greater one.
This article gives good details on the differences other than media...
Seems that HD-DVD/AOD makes it cheaper for the manufacturer to screw us as they don't have update production lines... but make us buy new decoding chips... and new software players/libraries,etc.
while Blu-Ray makes us buy scaled up chips on new media... i can see how computer makers would like this over HD-DVD as the software already scales up easily...
work the standards "circus". you get to travel to meet face to face to discuss technical issues on a standard. meet with other engineers in the same field/expertise, etc.
at this point in your life, you can get "in" with standards committees by doing a LOT of free work for it and presenting proposals and results. the university would pay for it and you can hook up with professionals in the field for a job that would be about the same...
do some work, travel to present results (usually in very nice locales...), rinse and repeat.
work that for a bit and you'll have more air miles than you know what to do with. especially since you've hit a lot of cool places already.
just be careful of getting stuck in the standards "circus"...
ok, so my coworker scores 2 unused tickets from his boss for ths show today. today is press/business only and not open to the general public. so we got there with 1hr left before the doors closed. we POWERED through things but if there were more people, you'd probably need the day.
current impressions: -show feels SMALLER than last year... my friend and I powered through it within an hour. we didn't stop at ALL the booths but some. of course, had to stop by the company's booth as well.:) -lot more korean developers in the house! -everyone is pushing for online... kind of like: the PC-internet era all over again... except with better and manufactured graphics -sony camp was showing off the EYE TOY... big time! giving out massive EYE TOY bags -capcom's SF2 brings back memories. i think this is the last version... i really want to play the ORIGINAL Street Fighter! oh man... -FF12 poster up! no other details than that. looks kewl. -MS was loaded with women... who choses their women?! not the best. "It's good to play together" -Konami's New Metal Gear trailer was playing... FRIKKIN AWESOME! extended version of the online trailer. way longer sequence. snake can do lots of cool stuff in the jungle -karaoke revolution ROCKS! there will be a subscription component with it for 1000yen per month. sign me up! HUGE selection in songs too! i am very impressed. -GT4 looks great! definitely need the wheel and pedals -Ratchet and Clank 2 is kewl -James Bond has a lounge. including women in evening gowns -magic has a booth there. got sample pack of cards... ooh. could be useful.:) (tip: magic in japan is: MTG for: Magic The Gathering) -capcom's merchanise booth has Street Fighter the Anime cells for sale! 200yen each, grab your own. there are a TON! look for a brown box in the corner of the shop
anyone going the weekend, GO EARLY if you're interested in the games... otherwise, go later with all the other "guys":)
I've been to the Tokyo Game Show for the last 3 years.. and every year, the XBox booth has had a LOT of scantily clad women... (not always hot, but they're just going for quantity over quality) way more women than stuff on display.
at the end of the day, they get them to line up for photos and it's like a miss universe contest... it's pretty sweet.
i don't care for what "gear" is at their booth, just bring on the girls!

the rivalry continues! so harvard, how do you respond?!
NASCAR was born from the whiskey runs during prohibition. Think about THAT.

ie. on the road: single processor running
jacked in: dual processor

is it me or it's a pure coincidence that MS decides to restart development on IE AND open up more source code?! could this "source" be IE?
huh-huh... "research".
ya, that's what I tell the girlfriend too when i don't want to show her my "research".
you really think this would get much time "in the rest of the world"? ha!
just get a good old wifi phone and you'll never know the difference.

you can still surf the web like it was 1997!
i guess not all of us have read the 256MB to 8GB RAM G5 test results...
some interesting results. diminishing returns after 1.5GB of RAM. (which is a good choice now)
i wish they had more video coding tests... especially for higher res....

?! i can get it for 3000yen here. i saw it as low as 2000yen for that mouse. where do YOU shop?!
also, it's great that you provide translation of the insert but 3000yen for a translation is pretty steep.
how much insight into the mouse do you need?! if you're that crazy about the design, you'd want more than just than just a page describing it...
my gawd! $70 for this mouse?! talk about a fucking mark-up! it's a LOT cheaper than that in Japan.
:-)
i'll sell it for $50.
was the frikkin' book! WITH ALL THE DETAILS AND SPOILERS!!!
