HD Up/Down/Cross Converter

The 7900 is a flexible, configurable Up and Downconverter for use in broadcast and post. It can process SD (Standard Definition) signals into HD, downconvert HD signals into standard definition, and perform Format and Aspect Ratio Conversion on both SD and HD signals. The 7900 and one of the optional audio sub modules together only occupy one slot in an Avenue frame – now that’s efficient use of space.
