Tally Management Option

The CommandCenter Tally Management option provides an interface to production switchers via native protocols for bi-directional exchange of data for both Tally and Mnemonics. It also allows for a cable map database and allows for signal path definitions for all devices including Grass Valley infrastructure. The Tally Management option provides conditional logic control of tallies (UMD tallies and/or GPIs.) It also provides an interface to GPI/O units and allows you to assign functions to GPI inputs such as CCU touch-downs. It also allows for management of UMD devices and provides support for common UMD/ multi-viewer protocols.

The basic tally system allows source tallies from cameras and other sources to be activated based on their contribution to the live transmission path. A source can be ‘On Air’ direct through a router for emergency mode, through master control via the router or through a switcher and master control or any other path that can be selected. The tally configuration is based on defining the various paths that exist (cabling) and the internal selections form the various devices (routers, switchers and master control. There may also need to be additional paths that are activated under special conditions such as emergency bypass. Tally connections to external devices is often through hard wired connections from a GPIO box but could also be via a network.
