The Video Function Driver is a part of the Jungo USBware framework and is fully compliant with the USB-IF Video Class Specification. It enables Windows XP, Vista and any other supported OSs to recognize the device as a standard video streaming device. Using the Video Function Driver, users can communicate with their USB video device through any standard multimedia application without the need for additional software on the host side.

A USB Class Driver is a Logical Device Driver (LDD), which controls USB devices that provide common functionality and are implemented in compliance with a specific device class.

A USB Function Driver is a driver implemented within a device in order to handle the device-specific functionality of a standard or custom USB device function. This driver provides the counterpart of the USB Class Driver.

Jungo's USB Video Solution is part of the Jungo USBware USB Device and USB Host Stack, that enables software and device manufacturers to incorporate standard USB device, function or OTG connectivity into their embedded devices.

The USBware Video Function Driver streams the video data through a dedicated isochrones pipe, thus utilizing the full potential of the USB bandwidth.

The USBware Video Function Driver enables both video streaming and still image capturing. all still image capture methods are supported by the driver including:

• Allowing the host to issue the image capture event
• Using the same isochrones pipe as the streaming pipe for the transfer of still images
• Using an additional bulk pipe to transfer images

In order to define the relevant descriptors information for your device the Video Function Driver is provided with an additional Configuration Tool.

The Configuration Tool uses a graphical application as a front-end to allow quick definition the drivers' custom settings for specific devices such as the USB descriptor information, incluing processing unit, contrast and number of cameras, without the need to write any specific code. The tool then automatically generates a new descriptor file, based on the information defined.
