Imagestore 750 Overview
Detailed Model
This diagram shows a more detailed view of the Imagestore 750’s video processing:
Each input (A, B, C, D, Fill1, Key1, Fill2, and Key2) can be individually selected as an SDI input
or one of 5 test signals. (Each SDI input can be subject to a rectangular clipping mask.)
Inputs C and D can be used as a (fill3, key3) pair. The Imagestore 750 can use any of its fill/key
inputs to receive clips from an Intuition XG processor. The Intuition XG processor produces up to 8
“XG keyer layers.” The Imagestore 750 sends commands to the Intuition XG processor that control
the playout of the clips.
Both the A and B side of the A/B mixers can connect to any of the inputs (A, B, C, D, Fill1, Key1,
Fill2, and Key2). Similarly, any of the DVEs can connect to any of those inputs.
The DVEs can also accept the output of the A/B mixer. The DVE output (either DVE1 or DVE2)
can be inserted in the processing path in one of 3 places: before DSK1, before DSK2, or before
DSK3. The DVE processing section is a purchase option. The DVE processor can be bypassed if it
is installed.
The Imagestore 750 has storage supporting internal keyers (logos, etc.). Inputs C and D can be used
as external keyer (fill3, key3).
The preview output can present video from one of several different tap points. Similarly, the clean-
feed (CLN) output and the monitor (MON) outputs can present video from several different tap
points.
Audio is disembedded from SDI sources, sent to the audio processing section, and re-embedded on
output. The audio is re-embedded in the PGM, PVW, CLN, and MON outputs.
