Taiwan Joining Chinese Royalty-free Video Disk Effort
BeardStreet writes "In an attempt to stop the flow of royalties to the various DVD licensing bodies (e.g. DVD6C, MPEG-LA, etc.), 19 Taiwanese companies have come up with a royalty-free DVD format called EVD which is compatible with a similar effort going on in China, called AVD. Capacity is about 1 GB higher. Their goal is to avoid having to shell out US $15 to $20 per-player royalties. EVD/AVD players will still be able to play traditional DVD disks but will not have the official DVD logo on them, thus avoiding the licensing fees. It's a political issue as well, in that China needs to balance the flow of royalty money going out of their country, especially with DVD players falling rapidly in price."
Let's get some US and European support in on this one and take over the market! But seriously, this is a really good thing we need to support these open standards to avoid the Information Nazi's.

If there are patents on the DVD format and these EVD players can read DVDs, it's hard to imagine how they wouldn't infringe those patents.
OTOH, if the royalties are for a trademark license, they may be able to escape by not using the DVD logo.
China said it was developing a format called Advanced Versatile Disc (AVD) that would be used only in the Greater China region
This format would only be used in China. Makes sense, since there's no way they could sell these players in the US or Europe because it would infringe patents. Even if it doesn't display the logo it still decodes CSS, MPEG, AC3, all of which are patented.
They'll still get exported, from stores like Lik Sang.. but who knows, customs will probably seize them at the border.
... the DVDCCA. And I hope it does.
If EVD is open and unlicensed then it will do one of two things, if not both: A) Expose the region coding for distribution control, or B) isolate the US (and possibly Canada) from getting any of these devices by legislating them illegal.
While we USians may not like the isolation, those who have the gold make the rules. This kind of open format will only help to spread the distribution of films made in other parts of the world, eventually hurting the DVDCCA and MPAA.
There's nothing like having inferior entertainment channels forced upon us by law and greed when we could all share and share alike the distribution method (like PAL and GSM).
Maybe these innovations belongs in the same ranks. Hopefully, the success level will be a considerable amount higher. ;-)
AHHHHHHH! I'm burning with goodness again!

Several industry sources confirmed that emerging EVD or AVD players will be capable of playing back both EVD/AVD disks and DVD disks.
But other industry sources in Japan acknowledged that if players bear no official DVD logo, it would be difficult for the 6C or 3C groups to go after them.
It's sad that some companies in Asia are going to get away with making their own DVD players for the sole purpose of cheating the DVD patent holders while some poor European kid who writes DeCSS so that he can play his legally purchased DVDs on Linux gets crucified to the fullest extent of the law.

watch this
Emphasis mine.
The difference that the move from MSFT centralises power and control in the hands of a corporation, while the move in Asia hands rights and restriction-free capabilities out to a whide variety of groups.
Centralisation and disemmination of power are very different things.
I don't suppose it has occured to you that China (Hong Kong included) has a thriving film and entertainment industry if its own and people there would like to watch their own country's films and see no point in having to pay a technology tax if they can develop their own standard. China *is* a big market and growing rapidly (~6.5% in Q1 2002)
A feeling of having made the same mistake before: Deja Foobar
As you say, Turing proved that the halting problem is undecidable; to be more precise, there is no general algorithm to decide whether a program will halt, that will provide an answer in finite time for any program.
That's okay. Detecting whether a DVD menu program is trying to die, the vast majority of the time, only involves special cases about which the halting theorem is silent. For instance, if the program halts by exuting the HALT machine instruction, you simply search for that instruction and replace it with your own code. If you don't trust the program not to modify its own code, you can run it in an emulator that constantly checks whether it is about to execute a HALT instruction. Consider that this is roughly what any modern CPU does in order to enforce memory protection.
Detecting infinite loops is a bit harder, and while you can search for trivial LOOP: GOTO LOOP constructs, you really need to run the program in emulation to get anywhere. You can, for instance, take a snapshot of the code and virtual machine state from time to time; if both ever return to the exact same state, you must be in an infinite loop (assuming you don't have interrupt-driven code to worry about -- if you do, expand the code under analysis to include the interrupt handlers, and repeat).
Moral of the story: not allowing the menu to die doesn't require knowing whether the menu program will ever halt, only whether it is about to. And that, far from being a theoretical impossibility, is a fundamental technique of virtual machine design.
Quantum mechanics: the dreams that stuff is made of.
