Introduction
Imagestore 750 Overview
This is a system block diagram of the Imagestore 750:
Fig. 2-2: Imagestore 750 System Diagram
Inputs and outputs of the Imagestore 750 include:
• Four SDI inputs, A–D. These accept HD or SD input.
• Two external keyer pairs (fill and key). Inputs C and D can be used for a third keyer pair.
• A GPIO connector that supports 16 GPIO ports (each configurable as an input or an output),
LTC, and Dolby metadata.
• 16 AES inputs and 16 AES outputs.
• Four SDI outputs (program, preview, clean-feed, and monitor).
There are also 4 COM ports and 2 Ethernet ports.
Other Transition Processors like the Imagestore 750
For the sake of discussion in this document, the term “Imagestore 750” includes the LGK-3901,
DSK-3901, and the ISM-3901, as well as the Imagestore 750 itself. These are transition processors
that fit in a 3RU Densité frame. These units provide a subset of the functions of an Imagestore
750. The master control system treats these units as if they were Imagestore 750s. They are
configurable using the Imagestore 750 Configurator and each has a browser application (for
remote management) that is similar to the browser application for the Imagestore 750.
See LGK-3901, DSK-3901, and ISM-3901 on page 11 for more information.
