NEC announces video checking technology


NEC has announced that its video content identification technology has been incorporated in the upcoming Mpeg 7 video standard

The technology creates a signature that is compared against one from the original file to determine whether the video has been altered. According to NEC this will allow the owners of the video to automatically "detect illegal copies" and "prevent illegal upload of video content" without their consent.

NEC works out how to triple USB 3.0 speed

Think SuperSpeed USB 3.0's 4.8Gb/s data transfer speed is lightning fast? You're wrong, says NEC.

Today it said it had successfully demo'd a serial bus that it believes can hit 16Gb/s.

Like USB 3.0, NEC's technology sends data as a stream of binary 1s and 0s. NEC actually demonstrated a chip capable of maintain such a data rate, rather than a new bus per se, but it shows there's room for the likes of SuperSpeed - or its successor - to deliver even higher data-transfer speeds.

At high throughput rates, signals become distorted, especially over long cable lengths.
