Screen ARK-X 000/I
The New ARK-X Universal Driver can be configured with just software selection and implements DVB-T/T2, ATSC, ISDB-T, DTMB, ATV modulations.
It can be used as a Transmitter, Gap Filler, Heterodyne Transposer, Regenerative Transmitter, Dual Cast Analog + Digital Multistandard
ARK-X UNIVERSAL DRIVER allows the selection of operation modes and total remote control:
• remotely, using a dry contact;
• via TCP/IP, using a LAN connection, web graphic interface, and a standard web browser
• via built-in SNMP;
• via a dedicated command inserted into the transport stream.
The New ARK-X Universal Driver optimizes the investments of both international broadcasters, reducing the transmitter types, and national broadcasters, thanks to its versatility in operation modes and configuration.
The New ARK-X Universal Driver is future-proof and guarantees a perfect upgrade path for new modulation schemes that will be delivered.
