Maryland Public Television Upgrades Production Control With DNF Controls Tally System

Maryland Public Television has installed a large Tally Manager system from DNF controls as part of a major upgrade to its facilities in Owings Mills, MD.

The upgrade to the main production control room includes a 4 M/E Grass Valley Karerra switcher, GV Kaleido multiviewer system, and a Utah Scientific 528x528 hybrid router, according to Joe Davenport, vice president of engineering at Digital Video Group, the Mechanicsville, Va.-based company that provided system integration services for the project.

Maryland Public Television generates hours of live and recorded local content each week, plus programming for PBS, so the entire project – from installation and testing to commissioning and training – was on a tight, two-week schedule. The DNF Tally Manager system serves as the interface between the Grass and Utah equipment. 

The DNF GTP-32 Tally System can send tallies to a remote truck, between rooms within a facility, across town, or anywhere in the world with IP connectivity.

Adding to the challenge, the room transitioned from CRTs with under-monitor displays to state-of-the-art multi-viewers, so the new tally control had to display multiple levels of four ME switcher status and exceed their old system’s functionality.

The GTP-32 Tally System features web-based configuration tools that optimize efficiency and permit individual device changes without impacting the whole operation. It can send tallies to a remote truck, between rooms within a facility, across town, or anywhere in the world with IP connectivity.
