USB 3.0 adoption might be moving slowly forward in the PC industry, but more and more peripherals are starting to appear in the market and if Taiwanese Genesys has anything to do with it, then we'll all be using USB 3.0 webcams soon enough.

USB 3.0 adoption might be moving slowly forward in the PC industry, but more and more peripherals are starting to appear in the market and if Taiwanese Genesys has anything to do with it, then we'll all be using USB 3.0 webcams soon enough. The company has announced its new GL3620 USB 3.0 webcam controller and it looking at demoing it at CES in early January.

We have in fact seen a very early prototype demo but this was using an FPGA instead of the actual finished silicon and to be frank, we weren't impressed. However, Genesys wasn't using the best of sensors for the tech demo and it'll be down to the wecam manufacturers to pick a suitable sensor to show of the capabilities of the GL3620.

The chip is capable of delivering uncompressed 1080p video at 30fps, something that shouldn't put too much strain on the USB 3.0 bus. Apparently a key feature is that the GL3620 supports isochronous transfer mode which apparently guarantees the bandwidth between the webcam and the host controller.

Thanks to a built-in motion JPEG encoder the GL3620 is also backwards compatible with USB 2.0. The built in HISP or hardware image signal processor as Genesys calls it, allows the GL3620 to turn the raw RGB data into interpolated YUV video and it can also do things like bad pixel correction, image scaling, gamma correction and image quality enhancement among other things.

The GL3620 won't go into mass production until the second quarter of next year, but Genesys will be demoing it at CES alongside its GL3520 USB 3.0 hub, its GL3321 USB 3.0 to SATA 3Gbps bridge and its GL3220 USB 3.0 memory card reader, all of which are already available.
