NEC has announced today that its video content identification technology will be supported in the upcoming MPEG-7 video standard, meaning content owners that release videos with the standard can “detect illegal copies” uploaded to the Internet almost instantly.
The company says each frame has its own unique signature, meaning that doing any editing to the file or analog or camera copies will completely alter the overall signature of the original video.
NEC says “these developments are expected to significantly reduce the time and cost of manual content inspections as well as improve the scale and accuracy of content assessment.”
Among the features of the video content identification technology are:
Accurate detection of copied or altered video content
Video signatures are extracted for each frame based on differences in the luminance between sets of sub-regions on a frame that are defined by a variety of locations, sizes, and shapes. Video signatures represent a unique fingerprint that can be individually detected frame by frame. This technology is capable of accurately detecting video content with that was created with such editing operations as analog capturing (*3), re-encoding (*4) and caption overlay (*5), which was conventionally very difficult to detect.
A high detection rate and low false positive rate for all video contents
By estimating confidence of signatures generated from each frame and using the confidence for sequence identification, the technology achieves a high detection rate (*6) with a very low false positive rate (*7). These technologies achieved an average detection rate of 96% at a very low false alarm rate of 5ppm (5 in one million) through tests conducted by the international standardization organization.

Mobile Crunch is reporting today that the popular music video game Rock Band is headed to the iPhone and iPod Touch, including premium content and 4-way multiplayer via Bluetooth.
The confirmation, says the article, comes from the CTIA convention where a kiosk dedicated to mobile Rock Band shows off a splash screen that says Rock Band for iPhone and iPod Touch.
The kiosk only shows the splash screen for about a second so there is little other info available about the upcoming port.
We will keep you updated.

Intel Corporation demonstrated the anticipated Larrabee graphics processor earlier this week at the Intel Developer Forum. Sean Maloney, chief sales and marketing officer for Intel, showed off a working version of the chip rendering a game environment built on ray tracing, a resource demanding technique for generating high-quality 3D graphics and often used with professional animated features.
The Larrabee chip was used in conjunction with the hexa-core “Gulftown” processor scheduled for release next year. The graphics processor is based on “Westmere” 32-nanometer architecture. Intel’s first Westmere-based chip is due to ship in the final quarter of 2009.
Maloney said that Larrabee will eventually be used for a discrete graphics card used in high-end gaming PCs and workstations. “We’ve got a discrete product coming up,” he said. It will be incorporated in system-on-a-chip (SoC) products for handheld devices, according to Maloney. He said it will be an easier programming platform for developers since it is built on x86 architecture.
“We’re keeping the programming model very close to what would be seen as conventional,” Maloney said. In the mean-time, Intel is reading new integrated graphics technology, an area that the chip-maker dominates in.
