Windows Vista proofed against video piracy

Microsoft is building unprecedented levels of safeguards against video piracy into the next version of its Windows operating system, Vista.

For the first time, the Windows operating system will wall off some audio and video processes almost completely from users and outside programmers, in the hopes of making them harder for hackers to reach.

The company is establishing digital security checks which could even shut off a computer's connections to some monitors or televisions if anti-piracy procedures that stop high-quality video copying aren't in place.

In short, the company is bending over backwards - and investing considerable technological resources - to make sure Hollywood studios are happy with the next version of Windows, which is expected to ship on new PCs by late 2006. Microsoft believes it has to cosy up to the entertainment industry if the PC is going to form the centre of new digital home networks, which could allow such features as streaming high-definition movies around the home.

PCs won't be the only ones with reinforced pirate-proofing. Other new consumer electronics devices will have to follow a similar set of rules in order to play back the studios' most valuable content, according to Microsoft executives. Indeed, assuring studios that content will have extremely strong protection is the only way any device will be able to support the planned high-definition content, the software company said.

Marcus Matthias, product manager for Microsoft's digital media division, said: "The table is already set. We can come in and eat at the buffet, or we can stand outside and wash cars."

Hollywood studios didn't get all the protections they wanted in Vista, and record labels have even seen some of their key concerns about copy-protecting CDs left unaddressed. But the Vista operating system as a whole goes much further than any prior general-purpose computing platform towards addressing content companies' piracy fears.

Although ordinary MP3 files and DVDs will play without any difference, the deep changes in the way the operating system handles some entertainment content will come with costs. The most obvious of these may be the risk of compatibility problems between some older monitors or TVs and Vista computers, particularly when trying to play high-quality video. Vista may also make it harder to do some casual copying, such as recording internet audio.

Matt Rosoff, an analyst with research firm Directions on Microsoft, said: "This is definitely being driven by Microsoft's desire to position Windows as a home entertainment hub, and to do that they have to make some concessions. They're walking a line, trying to please both sides [content companies and consumers] at the same time."

These changes are worrisome to some computer programmers and digital activist groups. They fear that increasingly high security levels will block off avenues of programming innovation, or even stop computer owners from accessing portions of their own machines - a little like walling off a room inside a private house.

Princeton University computer science professor Edward Felten, who has been an outspoken critic of rigid copy-protection rules, said: "There is a concern that there is a tendency to lock down parts of the design to protect the flanks of the copy-protection system. That makes it harder for everyone, including Microsoft, to adapt to new uses."

Several major changes have been made to the way the operating system will handle video and audio, though few of these are included in the early version currently in the hands of beta testers. The rest of the components are likely to be added in the next, as yet unscheduled, beta release and will be in the final launch of the operating system next year.
