When digital TV started, some components and parts were not available or hard to find, for example High Definition Modulators.
It was at that time that we at DigiSat decided to develop the required system components ourselves, using PCB boards and Firmware Made in Germany.
We have successfully manufactured, delivered and installed a number of different types of modulators & convertors, including Component, Composite, ASI, SDI, SD & HD, some installed many years ago and all of these are still running without failure.
Naturally this is not a cheap solution and not appropriate for every project, however the extreme reliability and flexibility to design the modulator according to the requirements justifies the expense for those very important projects.
