Main features
• Transmodulator with slot for CAM module.
• Generates an analogue channel from a scrambled MPEG2 DVBT service.
• The generated channel is single side band, allowing the configuration of adjacent channels within 46 and 862 MHz.
• Generates DVB and teletext subtitles.
• Both local and remote configuration & control capability.
• Monitor menu with quality measures (CBER) of the input signal.

The COFDM-PAL transmodulator with Common Interface allows to:
• Integrate paid-tv services in a free-tv headend, making both free and paid DTT compatible with every television so it is not necessary to replace the analogue TV sets.
• Used in headend for hotels, hospitals, etc... allows to keep the current CRT TV sets already installed.
• Protects of possible robberies of flat TV sets
• Only one remote control, same TV and same channel list than before the analogue switch off. Very suitable in installations where the service is provided to elderly or handicapped people.
