GENERAL:

The DVG-4090 acts as an analogue / digital video crash switcher and test pattern generator. On loss of video input, output is automatically switched to a choice of 16 test patterns.

8 custom built banners containing text or pictures, such as station logos, and 2 full screen pictures can be downloaded by supplied software. Single banners can be overlaid or keyed onto the test pattern output in the lower section of the video picture. In the case of an SDI input, these banners can also be overlaid onto the existing stream.

A countdown banner and audio test signal insertion is also available for link identification purposes.

The DVG-4090 is designed to fit IRT's standard Eurocard frames as well as IRT's 4000 series frame for use with IRT's SNMP system and may be used alongside any other of IRT's analogue or digital Eurocards.
