Macrovision CEO asks Apple to hand over FairPlay

tied-purple-picketFred Amoroso, CEO and President of Macrovision, responded to Steve Jobs’ open letter on Digital Rights Management (DRM) technology. Amoroso published his comments on his company’s Web site, as an open letter. In it, Amoroso suggests, that Macrovision take over stewardship of Apple’s own DRM technology.

Amoroso’s letter addresses what he considers to be four key points: That DRM has a broad impact across many types of content, not just music; that DRM “increases not decreases consumer value;” that it will increase electronic distribution; and that DRM needs to be interoperable and open.

Digital Music Playlist has a good writeup on the open letter. Be sure to check out the comments for a good laugh.

The slow death of DRM

From The Register — According to Steve Gordon, attorney and former Director of Business Affairs, TV and Video at Sony Music for ten years, the DRM walls are crumbling. Earlier this week, Steve Jobs called on the major record labels to allow online music sales unfettered by digital rights management restrictions.

Today, EMI is in negotiations with several digital music services to sell unprotected MP3s. Here is the long, sad history of DRM, and why we’re better off without it.

But instead of truly competing with “free,” Sony chose to sue Napster. That strategy lead to the emergence of other P2P services which simply took its place.

Three years later the major labels finally took their first serious stab at competing with P2P by launching MusicNet and Pressplay. But both services were mired by, and ultimately destroyed by, DRM. Neither Pressplay, from Sony and Universal, nor MusicNet, a service from EMI, BMG and Warner, allowed downloads or portability, thanks to DRM. They were stillborn and died quickly.

As an indication of how insignificant authorised digital downloads are to the music business, Apple’s four year slog with its iTunes store has grossed it less than $2bn, whereas gross sales from ringtones were over $6bn worldwide last year alone. And the growth of digital sales is definitely flagging. Although digital sales grew last year, the rate of increase was less than in 2005, and according toBillboard Magazine, in the year to come the US “revenue from digital downloads and mobile content is expected to be flat or, in some cases, decline next year”.

Is DRM to blame? Common sense suggests that DRM is a huge factor in the lack of growth in digital sales. As Steve Jobs correctly points out in his “Thoughts on Music“, the absurdity of DRM is that anyone can now buy a CD, and rip, mix, burn, and upload to their heart’s content.

“So if the music companies are selling over 90 per cent of their music DRM-free,” wrote Jobs, “what benefits do they get from selling the remaining small percentage of their music encumbered with a DRM system? There appear to be none.”

Making consumers pay a comparable price for a digital download, which at 99 cents per single roughly equals what you would pay for a CD, encourages them to steal. People don’t want limits on what they can do with the music, so consumers take the slight risk of an RIAA lawsuit and retaliate by downloading for free. Illegal downloads still outnumber legal by 40 to 1 according to the big label representatives, although insiders put the figure as high as 100 to 1. DRM is not serving these consumers, and that’s how DRM is hurting rather than serving the copyright owners it is meant to protect.

Study: P2P effect on legal music sales “not statistically distinguishable from zero”

According to an article by Ken Fisher over at Ars Technica, “A new study in the Journal of Political Economy by Felix Oberholzer-Gee and Koleman Strumpf has found that illegal music downloads have had no noticeable effects on the sale of music, contrary to the claims of the recording industry.”

The study compared the logs of two OpenNAP P2P servers with sales data from Nielsen SoundScan, tracking the effects of 1.75 million songs downloads on 680 different albums sold during that same period. The study then took a surprising twist.

“Using detailed records of transfers of digital music files, we find that file sharing has had no statistically significant effect on purchases of the average album in our sample,” the study reports. “Even our most negative point estimate implies that a one-standard-deviation increase in file sharing reduces an album’s weekly sales by a mere 368 copies, an effect that is too small to be statistically distinguishable from zero.”

The study reports that 803 million CDs were sold in 2002, which was a decrease of about 80 million from the previous year. The RIAA has blamed the majority of the decrease on piracy, and has maintained that argument in recent years as music sales have faltered. Yet according to the study, the impact from file sharing could not have been more than 6 million albums total in 2002, leaving 74 million unsold CDs without an excuse for sitting on shelves.

Blu-Ray AND HD-DVD broken

blu-ray_hd-dvd_logoCory Doctorow has posted an article on BoingBoing discussing the recent news that the processing keys for AACS, the DRM system used by Blu-Ray and HD-DVD have been extracted. This allows the content on EVERY Blu-Ray and HD-DVD to be decrypted. This news builds on the recent news that the volume keys for HD-DVD had been compromised. Quoting from Cory Doctorow:

AACS took years to develop, and it has been broken in weeks. The developers spent billions, the hackers spent pennies.

For DRM to work, it has to be airtight. There can’t be a single mistake. It’s like a balloon that pops with the first prick. That means that every single product from every single vendor has to perfectly hide their keys, perfectly implement their code. There can’t be a single way to get into the guts of the code to retrieve the cleartext or the keys while it’s playing back. All attackers need is a single mistake that they can use to compromise the system.

There is no future in which bits will get harder to copy. Instead of spending billions on technologies that attack paying customers, the studios should be confronting that reality and figuring out how to make a living in a world where copying will get easier and easier. They’re like blacksmiths meeting to figure out how to protect the horseshoe racket by sabotaging railroads.

Arnezami from the Doom9 forum describes the moment:

But then I realized why I first didn’t find the Media Key: it was removed from memory after the Volume ID was retrieved and the VUK calculated. I also saw that in my “corrupt” memdump the VUK, Vol ID, Media Key and the Title Key MAC were all closely clustered in memory: in the first 50kb (of the entire multi megabyte file!) but there were large empty parts around it. Almost as if it was cleaned up. This gave me an idea: what I wanted to do is “record” all changes in this part of memory during startup of the movie. Hopefully I would catch something insteresting. In the end I did something a little more effiecient: I used the hd dvd vuk extractor (thanks ape!) and adapted it to slow down the software player (while scanning its memory continously) and at the very moment the Media Key (which I now knew: my bottom-up approach really paid off here) was detected it halted the player. I then made a memdump with WinHex. I now had the feeling I had something.

And I did. Not suprisingly the very first C-value was a hit. I then checked if everyting was correct, asked for confirmation and here we are.

Windows DRM is the ‘longest suicide note in history’

University of Auckland medical imaging researcher, Peter Gutmann has written an excellent article on the impacts of Windows Vista DRM on the end user, YOU. A great read.

Original article can be found at:

http://www.cs.auckland.ac.nz/~pgut001/pubs/vista_cost.txt

This has ignited a debate again over DRM and its usage in not only the PC space, but is also relevant to other devices–such as STBs, mobile phones etc.

Executive Summary

Windows Vista includes an extensive reworking of core OS elements in order to provide content protection for so-called “premium content”, typically HD data from Blu-Ray and HD-DVD sources. Providing this protection incurs considerable costs in terms of system performance, system stability, technical support overhead, and hardware and software cost. These issues affect not only users of Vista but the entire PC industry, since the effects of the protection measures extend to cover all hardware and software that will ever come into contact with Vista, even if it’s not used directly with Vista (for example hardware in a Macintosh computer or on a Linux server). This document analyses the cost involved in Vista’s content protection, and the collateral damage that this incurs throughout the computer industry.

Big labels are “in trouble”, DRM is dead

Few people know the music industry better than Peter Jenner. Pink Floyd’s first manager. Jenner has also looked after T.Rex, The Clash, Ian Dury, Disposable Heroes and Billy Bragg – who he manages today. He’s also secretary general of the International Music Managers Forum. And he doesn’t pull his punches.
