Genesys Logic reveals USB 3.0 webcam controller

Genesys Logic introduced the GL3620, a new USB 3.0 webcam controller that supports lossless 1080p video at 30 frames per second as it has a theoretical bandwidth limit between the chip and the USB 3.0 host of up to 380MB/s. Don't expect a massive improvement in webcam streaming quality though, the upload bandwidth of most Internet connections can't even match the bandwidth of the original USB 1.0 spec.

The Genesys Logic GL3620 also packs native HISP, which encodes RGB RAW data from CMOS sensors to interpolated YUV format. It also looks after bad pixel correction, image scaling, gamma correction, image quality enhancement, etc., to maintain backwards compatibility with USB 2.0, probably albeit, at lower resolutions. The chip also includes a native MJPEG encoder that offloads the host CPU from doing the lossless stream to MJPEG conversion to stream to IM clients. Genesys Logic will exhibit GL3620 demo at CES 2012 in Las Vegas from January 10th to January 13th 2012. In related news, Genesys logic will also demo its three other new USB 3.0 chips, the GL3520, which is a USB 3.0 hub controller; the GL3321, which is a USB 3.0 to SATA bridge chip; and GL3220, which is a USB 3.0 flash card reader controller.
