"content protection systems" for DVD+RW

Not much has happened over the weekend, but Philips has announced version 2.0 of the DVD+RW specs last Friday. They include improved support for combining video and data files on the same medium, allow to allocate more space for menus, support more complex navigation systems and are prepared for content protection systems (I think we all agree that we could've done without that last point).

When i was reading content protection system, I thought great, something new that protects the content from errors. I was a little confused why we could do without it... Until I realized that I am the error!! Did I feel stupid...

I wonder when they get sued for misleading the customer... When someone bought this new DVD and cant read it anymore because he spilled his coffee on it. Than he claims that it should still work because of the content protection system....

No for that example you need a media protection system. Your content is safe if your media is safe. Content protection only serves content creators and IP horders. Content protection means absolutely nothing in favor of the consumer. In fact content protection is basically always a bad thing where the consumer is involved.

What I don't understand is what place content protection has on +(R)W media. It sounds like a good way for small-time distributors to encrypt their content rather than having to pay big bucks for pressing DVDs. Sounds fine to me.
But I didn't read the linked specs ...

i think (mostly a guess) that this is refering to CSS encryption support for replication, or it may be something entirely different, im still trying to find out exactly.

It looks to me like they are talking about the VR (real time recording) part of the specification. If so, this is probably "broadcast flag" support.

But if would be nice for authors if DVD+R/W had the ability that DVD-R(A) has, wouldn't it?

would be nice, but i was under the impression that +r already supported some (not all) of the DVD-R(A) features that DVD-R(G) misses out on?

Sheesh what idiots...
anyway I don't care. I got a box recently that strips out that stupid broadcast flag from analog broadcasts. Its called CGMA-A. So my DVD recorder will let me record anything now that comes in through its analog inputs :)

@atreides93:
Oh wow, I didn't realize that the broadcast flag was applicable to analog... That's some major suckage, there..I wonder how this will affect capture cards in the future.

I think he is meaning Macrovision. Not the digital no record flag. Macrovision has been around a long time and so have the devices to disable it. We have had one for over 15 years. And it will be the same for the digital flag if and when it is implemented. Which only goes to show how innefectual it is. All it takes is one person with such a box to digitise to a free format and then it is all over the net just like now. The only difference is that the average home user will have no rights to record anything any more. They are basically trying to overturn the precident set with the Sony Vs. whoever case where fair use was laid out. Only they are trying to do it without overturning that original ruling. It will still be legal to record publicly broadcast material so long as you don't bypass the encription. And they plan to encrypt everything and use it to limit the products usability so they can make more money selling people multiple coppies of the same thing. Bad mojo.

Seems Mpucoder was right on the broadcast flag.
