LGK-3901, DSK-3901, and ISM-3901
The LGK-3901 and the DSK-3901 are card modules that fit in a 3RU Densité frame. Each of these
units comprises an I/O card set and a backplane connector module. The Densité frame can
accommodate up to 10 of these modules.
Each of these modules can be regarded, from the standpoint of the iMC Master Control system,
as a reduced version of the Imagestore 750. Configuration of the modules uses the same soft-
ware: the Imagestore 750 Configurator. The browser application for these modules is nearly
identical to the browser application for the Imagestore 750.
LGK-3901
The LGK-3901 is an independent transition processor (also called a “3G/HD/SD Logo Inserter and
Downstream Keyer”) that can operate as a stand-alone unit with or without automation, or as
part of Miranda’s iMC master control system. Like the Imagestore 750, it operates in conjunction
with an NV9000 router control system, that provides video and audio sources, and one or more
master control panels, such as the iMC-Panel-200, that provide commands. The LGK-3901 issues
switching instructions to the NV9000 when it receives commands from a master control panel.
The LGK-3901 is essentially an A/B transition processor that inserts video effects (stills and
animation) and voice-overs into its output. It has several configuration options. The principal
software used is the “Imagestore 750 Configurator.” Note that a particular version of this soft-
ware is required for operation in the context of an iMC master control system: at present, it is
v1.5. Other configuration tools exist.
Version 3.0 of the LGK-3901 software and firmware is required for use in the master control
system. The LGK-3901 must be equipped with the master control option.
This is a “black box” diagram of the LGK-3901:
Fig. 2-3: LGK-3901 System Diagram
If you compare this diagram to Figure 2-2, you can see that the LGK-3901 has fewer connectors.
It also has some enhancements.
Inputs and outputs of the Imagestore 750 include:
• Two SDI inputs, A and B. These accept 3Gig, HD, and SD input.
• Two external keyer pairs (fill and key). Input B can alternately be used as the fill of the second
keyer pair.
• A GPIO connector that supports 16 GPIO ports (8 inputs and 8 outputs), LTC input, and 4 AES
input (pairs).
• Two SDI outputs (program and preview).
