Genesys Logic announced its newest application processor, the GL3620. This chip is designed to be the prime-mover of tomorrow's high-definition 1080p web-cameras, which will strike mainstream price-points. This chip takes advantage of the USB 3.0 interface, particularly its isochronous transfer mode, which guarantees sufficient bandwidth to stream uncompressed (lossless) 1080p (1920 x 1080 pixels) video at 30 frames per second. This defined theoretical bandwidth limit is about 380 MB/s between the chip and the USB 3.0 host. Lossless video streaming from the webcam gives users the ability to use higher-quality software video encoders.

Sooo.... USB 2.0 *was* holding back webcams? always wondered about that.


but then again, wouldnt the fact most internet connections are far slower than USB 2.0 mean this wont benefit much?

its easy to stream 1080p if you have a 8-20mb connection. anything under that and it might be too choppy

Im on 20mb and i live right next to the telephone exchange :toast: but yeah....UK is usually pretty bad for net speeds. I know a mate whose being charged for a 20mb package but only gets less then 2mb because of the area he lives in, but he cant do sh!t because they are the only guys who really do realiable internet there. some times it doesnt even matter about where you live. you can be in london and still suffer from poor speeds due to the old old old old network cables they are using that havent been changed in a few decades.

I have home a 1080p web cam. I always thought that the 1080p and even 720p quality looks like CRAP. Now I know why...:ohwell:
