Is there any evidence (or even suspicion) that either side here used either the patent filing or actual stolen technology to create their product? If not then the laws are clearly broken when we are allowing non-revolutionary ideas to be patented.

NVIDIA holds a very large graphics patent pool. In a lot of ways they're the successor to SGI, and in the interim have picked up companies such as 3dfx, which has further enlarged their patent pool. Which makes it very, very hard to efficiently implement a GPU without violating some of those patents. Proving malice may be difficult, but it's hard to imagine building a competitive GPU and not infringing on those patents.

As for whether the patents are revolutionary, that's a trickier point. If you researched into the same problems as NVIDIA a lot of your solutions would be similar/identical even without seeing how NVIDIA does it. But for a number of these patents the solutions are non-obvious; it's only after doing research and a lot of simulation do you come up with the same answer.

If that were the case, more of us would get mod points more often.

What happens is that the moderation system is biased against frequent visitors. Visit more than once a day and you'll basically never get mod points. Go away for a day or two and you'll come back to a heap of them virtually every time.

I'm not sure why Slashdot does this. One would think frequent visitors would be the people you'd want modding - someone who will see a story before it's too old - but perhaps they want someone a little less fanatical? Or maybe the mod points are to entice you to stay?

Why can't the iPhone have a ATSC chip inside it?

Standard ATSC (8VSB) actually doesn't perform very well when the receiver is in motion. Multipath is bearable for static receivers, but the addition of motion and doppler shift hammers the resulting signal strength.

There's actually an ATSC addendum to deal with this - ATSC-M/H - but to the best of my knowledge it has never been widely implemented. Of course even if it was, I'm not sure if Apple would want to spend the space on the receiver and the antenna (UHF is fine, VHF is not).

No this is Google favoring new standards before some browsers are quite ready for it.

Just to add to this, 60fps works fine in Internet Explorer 11 and in Safari as well. In fact both have supported it for some time. Of the major browsers, at this point Firefox is the odd man out.

It's like that because of the artificial restrictions placed on upload speeds by the DOCSIS and ADSL protocols.

Huh? There's nothing artificial about it in the case of DOCSIS. Cable was originally designed to multicast video using a shared medium. Putting Internet on top of that is a very clever hack, but it doesn't get around some of the fundamental assumptions and designs of the system.

To download data from the node to the user you merely need to put it on one (or more) 6MHz channels, and the user's modem picks up packets destined for it while rejecting the rest. It's functionally no different from cable television; if you can get a clean TV signal on any given channel, then you can receive packets.

However uploading data is an entirely different beast. The cable infrastructure was not initially designed for 2 way communication, as it was optimized for one strong node/head-end talking to many clients. The importance of that being only one device had to do the talking, and that it could do so loudly to make up for signal degredation. However once you're talking about clients uploading, you now have to deal with signal and scheduling issues. Long story short, the only practical way to do that from a signal integrity standpoint is to use a lower bandwidth, more error tolerant encoding scheme (QAM64 up vs. QAM256 down), and furthermore you have to do it in the lowest frequencies because higher frequencies attenuate too much.

The net result is that while you potentially have 100 downstream channels, you only have around a dozen upstream channels. Which operate at a lower bandwidth and have to be shared among many clients. Consequently you simply cannot do a symmetrical network over cable due to the benefits and drawbacks of the shared medium. The laws of physics get the final say here.

Barrier? I think the word you're looking for is "threshold" or even "mark."

It's not a barrier unless there's some property that allows you to hit 999GHz but not 1THz, which in turn requires extraordinary effort to surmount.

Just because you have achieved something new does not mean you have broken a barrier. At best you have broken the English language..

There is debate as to how much money the broadcasters will get in compensation, but there clearly isn't anyone looking out for the OTA viewer. I like some broadband too but this is the new titan fighting the old titan...

The problem is that both OTA TV and mobile communications are good - but not great - uses of limited wireless spectrum, so you have to weigh the pros and cons of each rather than having one or another that's an obvious better use.

OTA is a one-to-many transmission, making efficient use of the spectrum, but the transmitters and receivers are basically fixed devices. Mobile communication on the other hand is truly mobile, but it's one-to-one transmission. Neither is the ideal use case - one-to-many mobile - so you have to pick between one-to-many or mobile.

But the fact of the matter is that because TVs are fixed device wired is a perfectly viable alternative for them. Whereas a wired cell phone wouldn't be nearly as useful. So you won't find much support for OTA given the fact that most people find mobile communications more useful than OTA television.

Indeed, this is nothing new. It takes all of 10 seconds to find fake video cards being sold on eBay.

The sellers will simultaneously lie and tell the truth to skirt the rules and not get banned. Not that eBay actually cares about counterfeit goods.

Right now it's rebadging Fermi (400/500 series) generation parts as modern Kepler (600/700 series) parts. However it's an old scam, and if you go back a few years you can find G7x (7xxx series) cards that were being rebadged and sold as GT2xx cards.

The method of the scam hasn't changed: flash a hacked vBIOS to change the device ID so that it shows up as the desired card. And as long as sellers aren't prosecuted it will keep happening. There's just not much risk in this kind of fraud on the individual level. Though the scam in TFA is large enough that it's certainly going to attract more attention than the perps would like.
