USB video device class

The USB video device class (also USB video class or UVC) is a USB device class that describes devices capable of streaming video like webcams, digital camcorders, analog video converters, television tuners, and still-image cameras.

The latest revision of the USB video class specification carries the version number 1.1 and was defined by the USB Implementers Forum in a set of documents describing both the basic protocol and the different payload formats [ [http://www.usb.org/developers/devclass_docs/USB_Video_Class_1_1.zip USB Device Class Definition for Video Devices, Revision 1.1] , June 2005] .
