New Consortium to Push UDI and Include DRM

MarsGov writes "Intel, Apple, Samsung, LG, Nat Semi and Silicon Image formed a consortium to promote Unified Display Interface (UDI) as the new standard to connect computers to monitors and TVs. UDI will be HDMI and HDCP "anti-piracy" compatible. "

Defeat THIS piracy technique!

How about replacing the cathode ray tube in one of these TV sets with a dummy one?

From the current flowing in the scan coils, we can determine where the electron beam is on the screen {though to generate a standard timing signal, we really only care about when it jumps to the left hand side or the top}. From the three grid drives, we can get the levels of red, green and blue light emitted by the nearest pixel.

Apply some rudimentary signal conditioning which, if you could get the circuitry to fit on an A6 size piece of breadboard, you really would not be trying at all; and you have a set of signals suitable for feeding into any old-fashioned SCART socket on any old-fashioned TV set or DVD+RW recorder.

There is no way to protect any kind of content against the "dummy CRT" attack -- and once it has been successfully applied, the content is now unprotected for all time

Look to China

[DumbSwede]

Having been to mainland China recently I beginning to think they have things right in their economic model which is basically capitalism for things that are, well, capital. And communism for all things that are IP. With 25 years of 10% growth they are doing something right. So much so I felt compelled to write an essay on this only two days back (you can never go wrong pre writing stuff on IP or P2P for Slashdot).

Re:Hardware DRM Serves One Purpose

[Anonymous Coward]

The toll-collector aspect is twofold:

1) You have to buy hardware with DRM built into it -- otherwise you can't communicate with anyone else who's in the DRM chain.

Usually this DRM is protected by patents and/or trade-secrets, so every individual piece of hardware needs a license from the IP holder. At the very least, it requires knowledge of private encryption keys and/or registration of public encryption keys with a central authority. This probably won't be a free service, and by definition can't be a public service, otherwise the private keys will be exposed to the public and the system does nothing.

2) Despite what they tell us, a working DRM system cannot freely permit unscreened content from third-party, independent producers.

Here's why: if the system allows unflagged media to enter and be displayed normally, it allows an independent content creator to release non-DRM-encumbered content. It also allows anyone with the know-how to bypass the DRM on a single piece of licensed content and re-release it without the DRM. Thereafter, anyone using p2p sharing will just download the re-released, non-DRM version, and it will be appropriately non-flagged as if it were a piece of independent content. Voila, the DRM chain is broken.

Therefore, the only DRM system that has a chance of working is one that requires all content to be registered in some manner, even if the registration is provided without charge (at a loss) to independent creators. This means you can't distribute your newest novel without going through a corporate/government approval body.

It's certainly possible no functional DRM system will ever enter widespread use, and I hope this is the case. However, the only functional DRM systems will meet both of the above criteria. In my limited foresight, that is what the DRM supporters are actually attempting, only in small steps at first.
