Trinity Broadcasting Network centralizes with 10-channel digital master control

With the help of TV Magic, Trinity Broadcasting Network (TBN) has established centralcasting capability, completed a network-wide shift to digital broadcasting, introduced two new channels and created a tapeless platform on which to launch additional channels in the future.

TBN content is originated at the network’s Tustin, CA, master control facility, where the network just completed an overhaul to establish a digital master control system that includes nine SD and one HD channel.

The centralized master control system pushes content out to TBN’s 32 newly upgraded affi liate stations for DTV broadcasting and an international broadcast audience. TV Magic supplied the equipment and installed the system without compromising the operation of four existing master control channels running TBN, KTBN, The Church Channel (TCC) and JCTV.

The new digital master control system is built around Grass Valley Profi le servers and Sundance automation. A mirrored media access network Profi le system with more than 700 hours of SD and 50 hours of HD storage facilitates the ability to broadcast ingested material and maintain a robust backup to air. Sundance Titan automation has the ability to interface to the facility’s Myers ProTrack traffi c and operations software.

NVISION NV5128 master control switchers were chosen because of its independence from the station router, allowing a more traditional signal fl ow and greater redundancy. The switchers also allow operation of both master control hardware panels and software panels on any channel simultaneously. Three NV5128 frames accommodate the 10 master control processors.

Miranda products were used extensively for both multiviewing and modular equipment. Master control uses two Miranda Kaleido- K2 multiprocessors to feed Clarity Baycat LCD displays, creating the glass cockpit look in master control and also providing display redundancy in case of failure. Three Miranda Alto processors monitor all outgoing video and off-air returns, and are displayed around the facility. An extensive iControl monitoring and control environment facilitates quick triage of all signal paths.

All work positions use Avocent KVM user stations that allow connection to the more than 100 computer-based devices and equipment GUIs.

TV Magic provided component and system training, as well as training to familiarize TBN staff with workfl ows for ingest, asset management, and actual scheduling and playout. The iControl installed both in Tustin and at affi liate stations will allow further opportunities for consolidating network operations.
