Overview
The Imagestore 750 is a master control and branding processor for highly automated specialty
channels, capable of inserting up to four layers of graphics into HD or SD. The graphics layers
can be fed by an external graphics device such as an Intuition XG or from internally stored stills
and animations. The Imagestore 750 also offers character generation and clock insertion. It is
ideal for downstream banding or master control switching applications.
Its integrated audio engine provides multi-channel mixing and voice-overs. Audio is accepted
either as embedded SDI or from 16 AES input connectors. The Imagestore 750 provides 16-
channel audio mixing and playout with dynamic shuffling and gain control. Background audio is
automatically “ducked” during voice-overs. It supports multi-channel audio clip storage and
playback of up to 16 channels in four audio streams. Playback of stored audio clips is called Easy-
play 2. Advanced audio options include audio description (AD), stereo-to-5.1 up-mixing, and
Dolby processing with up to 4 Dolby decoders or encoders and sophisticated metadata
processing.
An extensive range of options and upgrades are available for the Imagestore 750, including
video A/B mixing, audio mixing, Emergency Alert System (EAS) and a temperature probe. Its
high-performance graphics capability includes dual-window 2D DVEs on both program and
preview outputs. See figures 2-1 and 2-2.
A template-based character generator (called Easytext) can insert crawl layers or static text
layers that are dynamically updated. High quality characters are output with 256 level anti-
aliasing, with easy control over drop shadows and transparency. Unicode characters in TrueType
fonts are available from 6 to 600 pixels, in any RGB color.
The Imagestore 750 has a master control option. This option turns the Imagestore 750 into a
powerful master control switching and branding channel designed for automated, multi-
channel environments. The option provides multi-channel arbitration for multiple panels,
channel branding (through Intuition XG or internal stores), video and audio switching and a
robust and scalable control system. The master control option is typically used in conjunction
with other associated devices such as automation, the NV9000 Router Control System, Intuition
XG, iMC control panels and monitor walls such as Kaleido-X. Automation drives upstream
content from video servers and causes the channel to synchronize router switches with appro-
priate video/audio mixing, graphics keying events, DVE moves, audio switches, and so on. The
