Knox Video Technologies has teamed with TV One who has developed its own proprietary technology known as CORIO2™. After careful evaluation of all the scaler technology currently available, the CORIO2™ processor was chosen for its flexibility and performance. Products based on other chipsets have a feature set frozen at the introduction of the product. Since the CORIO2™ video processing engine is entirely firmware based, it can be upgraded at any time by downloading the latest version from the support website and flash upgrading the unit in the field. This enables new features to be added to units many years after the initial purchase. This “obsolescence insurance” means that a CORIO2™ based product can always be upgraded to the latest version of that model.
