Blu-ray Is Cracked

From Slashdot:

HDCP Master Key Is Legitimate; Blu-ray Is Cracked

"Intel has confirmed that the leaked HDCP master key protecting millions of Blu-ray discs and devices that was posted to the Web this week is legitimate. The disclosure means, in effect, that all Blu-ray discs can now be unlocked and copied. HDCP (High Definition Content Protection), which was created by Intel and is administered by Digital Content Protection LLP, is the content encryption scheme that protects data, typically movies, as they pass across a DVI or an HDMI cable. According to an Intel official, the most likely scenario for a hacker would be to create a computer chip with the master key embedded it, that could be used to decode Blu-ray discs."

Open Source VLC Media Player Coming To iPad

From Slashdot:
The people behind VLC, quite probably the most useful media player available right now, have submitted an iPod version to the Apple software police. VLC — which is rightfully famous for having a go at playing just about any kind of audio or video file you care to throw at it — should appear some time next week, if it makes it through the often unfathomable approval process implemented by Apple. The Open Source Video Lan Client has been tweaked to run on the iPod by software developer Applidium

HDR Video A Reality
Soviet Montage Productions releases information on the first true High Dynamic Range (HDR) video using DSLRs
San Francisco, CA, September 9, 2010: Soviet Montage Productions demonstrated today the first true HDR video sourced from multiple exposures. Unlike HDR timelapse videos that only capture a few frames per minute, true HDR video can capture 24 or more frames per second of multiple exposure footage. Using common DSLRs, the team was able to composite multiple HD video streams into a single video with an exposure gamut much greater than any on the market today. They are currently using this technology to produce an upcoming film.
Benefits of Motion HDR

HDR imaging is an effect achieved by taking multiple disparate exposures of a subject and combining them to create images of a higher exposure range. It is an increasingly popular technique for still photography, so much so that it has recently been deployed as a native application on Apple’s iPhone. Until now, however, the technique was too intensive and complex for motion. Soviet Montage Productions believes they have solved the issue with a method that produces stunning–and affordable–true HDR for film and video.
The merits of true HDR video are various. The most obvious benefit is having an exposure variation in a scene that more closely matches the human eye–think of filming your friend with a sunset at his or her back, your friend’s face being as perfectly captured as the landscape behind them. HDR video also has the advantage of reduced lighting needs. Finally, the creative control of multiple exposures, including multiple focus points and color control, is unparalleled with true HDR video.
“I believe HDR will give filmmakers greater flexibility not only in the effects they can create but also in the environments they can shoot in” said Alaric Cole, one of the members of the production team, “undoubtedly, it will become a commonplace technique in the near future. ”

US Spends $11M To Kick-Start Video Search

From Slashdot:

"The US military is inundated with video from airborne unmanned aircraft, remote monitoring systems and security outposts. In an effort to speed up the processing and analyzing of all this video, researchers at Defense Advanced Research Projects Agency (DARPA) this week awarded an almost $11 million contract to open source software vendor Kitware to help develop what DARPA calls its Video and Image Retrieval and Analysis Tool (VIRAT) program."
