[Fernando]

Hi !

I would like to protect a DVD produced by me for not allowing copies no
authorized. How to do that?

Tks

This has nothing to do with electronics, look for Macrovision on the
web. But don't dream, every protection, especially on DVDs, can be
cracked. In the end, one could even hijack the signal coming out of the
dvd reader...

As They Should be:

DRM as-we-know-it is simply a ploy to get consumers to pay several times for
instances of the same product and for market segmentation; The real Pirates,
having ample ressources and means of mass production and distribution, will
rip the stuff regardless! If it takes a week more for them, no matter!!

I.M.O. The only real effect of DRM is to piss the paying customer off over
that he/she cannot f.ex. wach a legally-purchased DVD on the Laptop while
travelling or copy a few legally purchased tracks onto the MP3 player (and
actually *must* get the stuff off BitTorrent to be able to do so).

I don't know how to do that, but neither does anybody else.
Any DVD is easily copied.

Yes, it seems like a losing game. You can buy pirated stamped
region-free DVDs of every kind (even the newest) for a dollar or two
in some places. It takes them no time to do it. And when copy
protection has been attempted it causes problems with legitimate
buyers (anyone else have problems with _The Matrix_? And those huge
piles of blank DVD-R and DVD+R at computer stores, grocery stores,
Sam's Club etc? Nice to see people are backing up their data, or
perhaps there is a certain level of DVD piracy going on all around
us.. I'm told "one button" programs exist (and can even be downloaded)
to do the copy and compression if required. Maybe the new generation
of HD DVDs will have more secure protection. Or maybe that will kill
acceptance if enough people have become used to pirated copies.

A guy selling video game cartridges and writers in HK (for Nintendo
Gameboy Advance SP) offered to throw in two DVDs packed with 2,000+
ROM cartridge zip files to sweeten the deal. The original cartridges
sell for $50 US or so each. <sigh>. The only game company that I know
of that's been able to contain the pirates is Nintendo with their
Gamecube- they did this by using special mini-DVD hardware AND
software. After a couple of years, the only thing the pirates have
been able to come up with is to do a $75 US modification on the
machine, after which it will be able to read downloaded and burned
mini-DVDs. I think the engineers who came up with the protection
scheme deserve a big bonus.

Put it into a bank safe, and certainly don't give it to anyone.

I doubt copy protectoin will go away any time soon...

As it is now, it's trivial to pirate DVDs. Even without a 'digitally
perfect' copy, so long as DVD players produce an analog signal output, it'll
be easy for the 'professionals' to just make one unprotected copy by
re-digitizing the analog output, and they're set. Hence the push for secure
(encrypted) digital links all the way into the TV set or monitor itself...
I don't expect that'll happen any time too soon, though -- as far as I can
tell, one of the biggest sellers at Radio Shack these days is an RF
modulator to take the composite video output of a DVD player and use it with
their pre-historic TVs!

When I bought our first DVD player we had to get a new TV (I think
because of some copy protection BS, but I could be wrong). It would go
blue-screen under some conditions. The old Sony didn't owe us
anything, but it was a bit of a PITA to add the cost of a new TV to
the $300+ that the early DVD players cost. An RF modulator would have
gotten around it, but with unacceptable loss of quality.

Secure digital links all the way into a TV set may be a prerequisite for
HD broadcast of many movies. I believe that the current battle over the
'broadcast flag' is aimed at this very goal.

If the tuner cannot establish an end-to-end encrypted link with a
trusted display, it must down-convert to standard resolution. This will
keep perfect digital copies of the HD program from being made off an
insecure link.

Guess what? Today's DVDs are 'standard resolution' already. Until new
DVD technology is brought to market, one needs to down convert a HD
source to burn a DVD anyway. So this helps pirates, not hinders them.
Furthermore, from current experience with pirated media, those willing
to purchase it aren't too picky about quality anyway. Many pirated DVDs'
original source is a handheld camera slipped into a theater.

Worse yet, recording from an analog signal will strip any digital
watermarks from the original data stream. A re-digitized source
transmitted over the internet can't be automatically identified by
sniffing for the watermark at ISPs or routers. If the studios were to
allow unencrypted streams between equipment, most pirates probably
wouldn't go through the trouble to try to detect and strip embedded
identification and, as a result, automated anti-piracy methods would be
feasible.

In fact, you need a direct, encrypted, digital link directly
into the viewer's brain. That, and an "erase memory" button
*might* make it safe from illegal copying. ;^)

Absolutely, and despite the marketing push to start selling people HDTVs,
it's still very uncommon to walk into a store and actually see a TV set that
isn't running with its contrast cranked so far up (often the factory
default) that it destroys a lot of the resolution potential the display
could have had with high quality input material. (On the other hand,
perhaps one could view this as a means to sell more LCDs and plasma
displays... fewer opportunities to screw up the picture...)

 

MicroSoft makes the DigitalRightsManagement system available for use.
You need to download the Windows Media Format 9.5 SDK
from here:

Then, when you install it, search in the help for DRM.
