Moving images are constructed from component images using the animation
builder software provided as part of the Media Conversion Software package
supplied with Imagestore HDTV.
Component images are imported into the animation builder utility from 32-bit
Targa image files thus allowing components to originate from almost any
computer graphics system.
AB Mixer
The optional integral AB Mixer (MIX-HD-001) video switcher is designed to
be fed by any of the unit’s input sources or by an external router under
automation control. The mixer provides cut, cross and V fade transitions with
variable fade rates.
Timing, Control and Automation
Imagestore is designed to be easy to install. One line FIFO’s are provided on
each input for simplified system timing.
Other valuable set-up and control features include a menu-driven front panel
VFD display, a General Purpose Interface (GPI) macro editor and a facility to
load configuration settings from, and save system configurations to, a floppy
disk.
