Trilogy Communications is formally launching Watchdog at IBC2012. It will be demonstrated alongside the Mentor XL SPG and Trilogy’s intercom products on the company’s stand.
Watchdog is a card-based detection and changeover system, allowing flexibility with any combination of active detection and passive switching options.
Each card can monitor main and backup signals for a range of reference signals, including SDI test patterns and as well as black and burst, AES, LTC and tri-level sync.
The Watchdog detection cards automatically determine the input format and compare the quality and precision of the two inputs, not just presence or absence.
The cards are used in 1U or 2U standard frames, which allows for complex switching systems to be constructed with multiple cards or for the switched outputs to be routed to distribution amplifiers in the same unit, saving rack space and cabling. The 2U frame also accepts redundant power supplies for an additional layer of resilience.
A typical configuration would comprise two Mentor XL SPGs and a Watchdog Changeover with a choice of cards and a powerful software control system for configuration, monitoring and remote control.
“Watchdog builds on our successful Mastermind changeover unit, responding to suggestions from our users,” said Barry Spencer, General Manager of Trilogy Broadcast. “Customers told us they wanted a more modular approach allowing them to tailor the changeover to their own application, as well as the need for integration into command and control and redundant power supplies. We responded to these requests and are very pleased at the response Watchdog is already seeing.” – Monica Heck
