The VB256 ISDB-T(b) RF input blade brings support for the latest ISDB terrestrial modulation standards to the VideoBRIDGE product line. With support for all modern ISDB-T system modes, the VB256 includes all the modulation formats needed to monitor modern ISDB-T broadcast systems. Each VB256 includes two independent tuners. One is enabled by default and the other is enabled with the VB256RF-LICENSE. Together with the VB120 or VB220 controllers, this allows up to 4 RF inputs in a 1RU chassis.
