Re:I'm confused... or this is super sinister.
The truth seems to be a variation of #1: the writer at PC Authority didn't actually read the press release (alternative hypothesis: did read the release, and is not only innumerate but moderately mentally retarded), but rather made up speculative, mostly incorrect bullshit based on a blog reporting on a blog reporting on...a blog reporting on the actual press release. Like a fucked up internet game of telephone where the original source was there for the picking but still willfully ignored.
The secret sauce actually fingerprints video frames in a way that is invariant against most common alterations, including reencoding, analog capture, and hard-subs. Minor changes to the video...will leave the signature largely unaltered. No more manual checking (or keyword-search DMCA mailings?) for copyright violations. -
TFA is worthless, inspired by third-hand rumor
The firm touts the efficiency of its algorithm, saying that a bog standard PC can search through 1,000 hours video in just one second. Quite what the firm's definition of a "home-class" PC would be interesting to know as we can't quite figure out how even a dual core 3GHz box can go through the 104 billion checks for 1,000 hours of video in a mere second.
1000 hours of video has close to 104 million frames; that would yield around 60 cycles per frame on a dual core (i.e. old) box.
The innumeracy of the author aside, what does this technology even do? Apparently altering the video, even minutely, will alter the "signature." Much like...CRC-32...very cutting-edge. We should name this startling development; I nominate the word "hash." Stupefied by the summary and the "article," I turned to the actual press release to find out what the technology really (purportedly) does.1. Accurate detection of copied or altered video content Video signatures are extracted for each frame based on differences in the luminance between sets of sub-regions on a frame that are defined by a variety of locations, sizes, and shapes. Video signatures represent a unique fingerprint that can be individually detected frame by frame. This technology is capable of accurately detecting video content with that was created with such editing operations as analog capturing (*3), re-encoding (*4) and caption overlay (*5), which was conventionally very difficult to detect.
...
4. Compatibility with home PCs By designing a compact signature size of 76 bytes per frame, the storage memory required for the matching process is minimized. As a result, a home-class PC (*8) can match approximately 1,000 hours of video in 1 second.It turns out that a home-class PC ("A single core CPU with 3GHz clock speed was used for testing purposes. Signatures were stored in the main memory.") is able to match 1000 hours that have already been hashed in a single second. No doubt it takes considerably longer to actually calculate the signatures. The power of the algorithm is that when the video is altered (in human-recognizable ways) the signature doesn't change much. Ah, things are starting to actually make sense. The truth is (surprise!) the opposite of the linked phrase in the summary.
This technology may allow automated, accurate matching of copyrighted video on youtube or other video sites...who cares? That is already being done, only less accurately. The law would have to change rather drastically for it to be mandated that everyone includes correct hashes in their MPEG-7 video. That is hardly necessary--I'm sure someone will spare the cycles to hash the videos and inform content owners. Like they do now...only better. Maybe next time we can all have fun panicking about the "FaceRecognition descriptor" (only the TOC/summary is free) instead. Really, the 76-byte signature is just an implementation of the metadata schema for MPEG-7. The algorithm should work for any format, however (otherwise it would be rather trivial to evade!).
The only interesting thing I have learned is that NEC's algorithm uses robust, compactly representable edge detection (maybe) to compare short clips of video with extremely high accuracy; yay, computer science. All of this escaped Lawrence Latif, author of TFA (such as it is), who didn't see fit to RTFA himself before he started blogging his paranoid fantasies as fact. I wonder just who the "anonymous reader" that submitted the summary was? -
Terrible reporting
Press release Let's see - 1000 hours of video = 3.6 million seconds = 108 million frames (30fps). Not 104 billion.
The signature is just 76 bytes. But a "home class PC" is 3GHz according a to a footnote. Perhaps the reporter could have read the original press release.
This stores the difference in luminance between subregions of frames. No idea why this needs to be encoded in the video itself. Seems that all a pirate needs to do is tweak things adequately so the signature changes. And I don't quite see how detecting changes is a feature. Surely you're trying to detect things remaining the same... -
Not really a battery
The device they came up with is more like a supercapacitor, but it still pretty good.
I believe that the real breakthrough in electrochemical energy storage technology will not be in greater energy density from new materials, but in cheaper alternatives from organic systems.
When their performance degrades too much we can safely toss them, make compost and start over.A couple of examples:

Re:Gap between computer science and person problem
What you're missing is that an ontology system like cyc has hundreds of thousands of such assertions, and has reasoning capabilities of basic abstract concepts such as 'things', 'temporal things', 'spatial things', 'intangible', etc.
Check out this diagram. Cyc has 1.4 million assertions. How long will it take you to finish your program? How long to troubleshoot? ;)
Cyc has a language for making assertions. It has no ambiguity. In my example of the IM interface, cyc could determine ambiguity and ask clarifying questions. -

180g NetBSD server
I submitted this back at the slashdot.jp announcement, but it was rejected here, and now I hate slashdot.
NEC is working on a 180g NetBSD-based server. The Univerge WNX is targeted at low noise, space economy, wereable computing, and on-the-fly multimedia processing. They claim a single person can use it with a mini-camera to brocadcast real-time video and audio (through wireless LAN/FOMA) and record the data at the same time, with two CF slots. Cool gadget. Japanese press release (with pictures). -
Re:Higher unit cost for Blu-RayBlu-Ray seems to have more support from the companies that matter right now: Sony is using Blu-Ray in the next Playstation, and blu-ray.com lists many the companies in the Blu-Ray Consortium as "Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson", which points to Blu-Ray's support in the PC industry. And with Sony's support in the gaming industry, and Dell, HP, Sony, Apple and others' support in the PC industry, I think people will be more likely to have a BD-ROM(Blu-Ray) in their house.
Also, contrary to what you may have heard, Blu-Ray discs will not require a cartridge. Blu-Ray discs should be more scratch-resistant than even current CDs and DVDs.
And about capacity: HD-DVD can only hold 30GB(15GB per layer), but Blu-Ray can hold 54GB(27GB per layer). In the future, Blu-Ray discs could even hold up to 200GB.

Re:Mis-targeted?
I think this might have something to do with that decision:
NEC is also developing a recharger for the battery that can be used at home as well as working on a way to prevent excessive discharge of power from the cell.
It looks like right now the battery is good for high amp charge/discharge but they still need some work to safely power low amp devices.
From the discussions below, one also gets the impression that this thing needs one hell of a charger to charge it in thiry seconds which would explain why they are still working on a home charger.
But this looks really promising. Other documents mention that organic radical batteries are being researched because they are more enviromentally friendly , and because they could have a better energy density. And now this article says they have quick recharge and near capacitor like discharge capability, and are competitively priced. I don't know how many of these properties this particular battery has, but it would be pretty amazing if it had all of the above. You'd think that they would have mentioned it in the press release though, so I have to assume not. -

Re:Don't read the article!!! [don't worry]Hey relaaaaaaaaaaax...
Its only Microsoft style innovation we're talking here (in future referred to as Microvation).
The way you do things is take an existing product or range of products, copy 'em, brand 'em and market 'em to hell.
e.g.
Take NEC's personal robot and call it a Robie.
Take the common idea of controlling another device with a PDA and make it sound like a pocket PC microvation
And of course, you really need an advanced research division to come up with a "a program that acted like a magnifying glass for Web sites"
I was going to have a dig at the "The system uses compression technology to turn photos into data and encryption techniques to make forgery nearly impossible"...but hey - its just waaaaaaaay to easy.
Bottom line. Nothing new to see here.

And yes, the memory stick format is much more expensive
I just paid $30 for 128 MB MS. Show me a better price for CF or SD/MMC.
not to mention has various confusing variations (e.g. magic gate)
You mean 2? Magic gate, non-Magic gate? Boy, that is confusing.
and is still proprietary
"Proprietary", eh? Guess what? All of the major formats are proprietary. Want to sell a CF device? You can if you ante up to the CF org. Sony has released quite a few specifications (http://www.memorystick.org/topics/eng/aboutms/for mat.html).
You might find prices on Amazon.com come close to CF or SD/MMC but I can walk into any camera shop and be offered compact flash cards by 3 or 4 manufactures where I'd be lucky if could find 2 for memory stick.
I count 6 manufacturers of Memory Stick: Lexar, SanDisk, Sony, I-O Data, Apacer Tech.

For those of you who don't read Japanese...
For those of you who don't read Japanese, I give you a bit more info on this. Based upon what I read here (Yahoo News Japan), it is a Pocket PC 2002 (which is no surprise, as NEC makes one of these in Japan). They are also hoping to make versions for other languages as well. What's written there seems the original Japanese of the post in Digitimes. And here is the press release from NEC.
Based upon what it says on NEC's press release, it works via voice recognition, not via phone as somebody suggested. It is tuned to understand standard American English (whatever that means) and standard Japanese (which is well defined). The recognition is based upon common words used for tourists, so if you try to translate technical terms, it probably wont' understand you at all. Just like many voice recognition, the way how you speak will determine the accuracy of voice recognition (with a thick accent, you won't go anywhere).
They will have special booth set up for this for evaluation of the technology in Narita Airport in late June.
It probably works via voice recognition and translation engine. Voice recognition is something that has been being developed everywhere as you know. English-Japanese translation engine is something that Japanese has been working on for a number of years, as Japanese is very different from any other language, and pretty much useless outside of Japan, as nobody else speaks Japanese.
Based upon my experience with these translation engines I have seen in Japan, they work very poorly. You will get most ideas across, but the sentences are very unnatural at best, often incomprehensive. Of course, these are often a lot better than English written by most Japanese. I personally think it is nearly impossible to make really good English-Japanese bi-directional translation engine, as Japanese grammers are so erratic and loose.
Of course, these devices/softwares probably are better than nothing if you know absolutely nothing about the language... -

-> Are corporations going to use this in their board rooms? Not if they're concerned that their next M&A deal is being recorded remotely by their competitor via a "Silent Helicopter" circling the 50th floor... Yes, it's possible to do that creepy Van Eek (sp?) thing (assuming it's a CRT and not LCD), but I'm not talking about the NSA's creepy helicopters.
Follow up:

Re:Licence revoked:
The automatic gain control on the low noise amplifier in the receive section of the card would shut down the receive path for any card inside the structure where the 100 watt omni is located. Think of when you yell into a mike and it cuts out to protect itself. So, you could provide strong signal to everyone, unless they were too close to you.
And as the article mentioned, this applies to Packet Radio, which by it's nature has a single source and a single destination. Omni directional antennas are used primarily for point to multipoint communication not point to point as is typically used for packet radio.
Also, remember the inverse square law when designing your network. Putting more power into your transmitter does less to improve communications performance at a distance than a properly designed antenna. High gain omni directional antennas are more efficient at propagating your signal than increasing your power to 100w.
For instance, a 15 dBi High Performance Omni sold here for $209.95 increases the effective radiated power by a factor of 100,000. A factor of 10 for every 3 db of gain. So, your standard 100mw transmitter would transmit less power than the 100w transmitter initially, but would fall off less with distance, surpassing the performance of a 100w transmitter on a standard antenna after the first few feet.
The other route is to use a 2.4 Ghz Klystron like this that costs in the neighborhood of $30,000 which of course can be coupled with an high gain antenna, which will not survive long at its maximum rated load.
This is not a competition of Penis sizes or "My athlon is faster than your Intel boxen" this is a game of finesse where the sharpest mind and the most efficient system dominates through signal quality, not signal quantity.
You get Mary on her 2.4 phone and the Muni Hospital complaining about you ruining ther gossip chat and emergency beeper service and you won't just loose you expensive 'leet 2.4 Ghz gear, you will do prison time for willfully jamming vital communications services, tantamount to a terrorist act, post 911.
Want to be 'leet? Implement a flat panel phased array with electronic beam steering to pinpoint your distant end receiver at gain levels limited only by the precision of the real time clock you use to gate the injection of the 0-180 and 180-360 phases of your waveform.
That would cover as many stations as you wanted, within the limits of line of sight. You could go back to college to learn the RF theory necessary to build such a device for the price of a big dumb klystron and go on to dominate the mobile gigabit bandwidth telecommunications arena. Perhaps your choice is clear.
'cept you have to compete with me, and I'm 11 years ahead of you :) -
NEC might dissagree.They may not sell IBM mainframes, but they do sell mainframes. See NEC supercomputing. See this page for an interesting view of computing in Japan.
I imagine that any self respecting country would have some kind of indigenous dino maker. Let's see. Germany? Nope. UK? Nope. Similar pages can be found for France. Bully for Germany and Japan for at least trying, but it looks like the US kicks ass in this field. I suppose that you can charge alot when you make something others have a hard time keeping up with.
We shall see the merits of the case.

NEC Polymer Proton Battery

Re:Beyond 80 Gbps already?
Indeed, upon further research, we're already way beyond 80 Gbps on a single fiber. DWDM (dense wave division multiplexing) can increase the capacity of a single fiber to 1.6 Tbps, and soon to 3.2 Tbps with 80 wavelengths at OC-768 according to this press release from NEC. As the press release states, a 3.2 Tbps data rate is the equivalent of transmitting 1600 feature-length films every second.

Re:Transmeta Smarsmeta...
Well it depends on what kind of embedded device you're designing, but in many cases the MIPS processor fits the bill better than ARM. MIPS processors are designed by many different vendors, and each has their own target market. The MIPS architecture has seen a massive growth in the embedded market in the last few years and there are some impressive processors out there from the low end to the extremely high-end.
StrongARM is well positioned for handheld devcies, but I'd say the MIPS architecture is the most promising in the embedded space over all.

NEC press release
A press release from NEC, dated May 30, 2000, is at <http://www.nec.co.jp/english/today/newsrel/000 5/3001.html>. There are also links to more current information, in both Japanese and English.
According to the press release, the system has 640 nodes with 8 vector processors each, for a total of 5120 CPUs. Each node has 16GB of shared memory and has a peak performance of 8 GFLOPS.
The system runs NEC's SUPER-UX Unix-based operating system, and supports Fortran90, C, C++, HPF (High Performance Fortran), and MPI2 (Message Passing Interface). -
Re:Implications for alpha?
There's potential for MIPS too: there are lots of vendors bring out some very impressive 64-bit MIPS processors. PMC-Sierra has their new RM9000x2, SiByte has something similar and NEC has some 64-bit offerings as well. Granted all of these chips are targeted at the telecom/datacom market but the technology could be adapted for use in servers if necessary. Still, it is sad to see the Alpha go.

Here's something REAL...Lithium ion batteries are nothing new.. as many of the more informed posts have already stated. However, here is something real.
This is not lithium, but rather quinoxaline in sulfuric acid.

Re:We need to get off Fossil Fuels
The computer that I am writing this post on is powered by coal. What happens when (and if) all the fossil fuels are used up?
We'll never use up all the fossil fuels. We never used up all the spermaceti (though we came close), but we don't use it any more regardless. It's just not economic.There are a number of economic and technological forces moving in the favor of alternative energy. To list a few:
- Electricity from wind is now below US$0.05/KWH, and the trend is still downward. (The problem with wind isn't the supply, it's that it isn't available on-demand. Storage technologies are key to making wind really workable, and storage is still very expensive except in a few places where there is very favorable geography.)
- Electricity from photovoltaics is about 5x more expensive, but falling pretty steadily. Figure that it's about 10 years behind wind. Storage is the same bugaboo.
- This year saw a surprise, when it was announced that a common every-day one-celled alga could be made to produce pure hydrogen just by denying it access to light and sulfur. Efficiency is already 1%, and the researchers think they can get it to 10%. Consider what the output of a thousand acres of desert might be...
- New batteries are on the way, the NEC proton polymer cell is just one of the more interesting.
- There is a lot of room for improvement in the form of co-generation and other advanced technologies. Fuel cells which heat your house and your shower as a by-product of making your electricity are already on the market and ready to take over lots of functions. When hydrogen comes through the pipeline to your doorstep, anyone with a fuel cell will be ready for it.

Non-sequitur
Hold it right there. That assertion is false, therefore all that follows is false.If I was made Prime Minister of Canada (yes, that's where I live) my first order of business would be to ban all fossil-fuel burning personal use automobiles!!!
Then I, as an affluent and intelligent young Canadian, being forced to ride on public transportation...The day is coming very soon when you won't even think of burning fossil fuels to get somewhere. You could get one of VW's 78-MPG cars today, and run it off of spent fryer grease (but you'd be a bit eccentric). Or, wait a bit and you'll be able to get something like the tzero, which already has acceleration better than anything made by Mopar. That's with current batteries, too. When you consider the performance potential with new batteries such as the NEC proton polymer battery, you could be talking 0-60 in 3 seconds. That's more fun than I've ever had.
Banning cars will cause the affluent to leave.
Using gas taxes to push electrics will have the wealthy enjoying the quiet and clean lifestyle first. After all, most of the early adopters are either rich or upper-middle class. And you can bet that the auto companies will just love a ban on gas-burners once they've got production of electrics ramped up. Forcing replacement of the existing fleet is a bigger market opening than the replacement of R-12.You say you're affluent and intelligent, why aren't you on this bandwagon already?

does your laptop use 200mA? I think not. A small motor uses about that much. And even then, it'd only power that 200mA motor for one hour.
Bunch of misconceptions in this response.- A 200 mAH cell does not have to be discharged at 200 mA or less. The press release said "in a 200mAh device, 9A in 10 seconds" (whatever that means).
- Nothing in the press release mentioned how big this 200 mAH cell is, how much it weighs, or the voltage. That 200 mAH cell might be the size of the end of your pinky finger, in which case a decent-sized battery would be umpteen amp-hours. I can't tell from what's given.
- One can make some educated guesses of the density from the description of the materials; the plastic electrodes probably have a density of less than 1.5, and the sulfuric acid electrolyte is probably 1.2 or less. Contrast this with metallic lead's density of (11.3.)
- The energy density is comparable to lead-acid, but the power density is far higher. If surge discharges can be done at a rate of 45C for 10 seconds, this implies a peak power output of 450 KW from a 10 KWH battery pack. This is equivalent to about 600 horsepower. With the proper power electronics and motors, an electric car with these batteries could eat Corvettes for breakfast. Taking a full charge in 5 minutes means that regenerative braking is a lot easier, and so is quick charging.

article submission
Timothy doesn't read Slashdot
Posted by timothy on 04:20 AM April 1st, 2001
from the at-least-read-the-front-page dept.
Frac writes: "It seems rather obvious that timothy doesn't read Slashdot, considering that the an article still on the main page mentions the exact same news." Interesting stuff. And in other news, there are now proton polymer batteries available, results from ICANN elections, and a really interesting article at ZDNET on reverse-engineering. -
Re:Imagine...
Do you think you are joking? See below.

BTW, the NEC SX-5 - unlike massively parallel architectures - can effectively run near its theoretical peak performance for most applications, I'd say that the top 40 TFlops performance is a rather conservative estimate (NEC will have newer and faster technology by the time this beast starts being built).
