Have installed many satellite systems, started installing for Cinema's and Theatre's when  New York  USA's Met Opera introduced alternative input, just after Optical projectors were phased out for electronic one's to take Digital Cinema.   

 Our background was in Broadcast, ITV company employees,  we installed, set up, maintained, and operated all of the broadcast and studio electronic equipment, untill  the jump to computer broadcast equipment, with backup service that was outsourced.

The engineering base was then no longer needed, so we went to pastures new.  First we moved into Satellite communications which was taken on by Television Companies for News Coverage, We  then found Cinema's and Theatre's needed help   , with their move from film to digital. This was much like Television was like in it's" HEYDAY"
