AUDIO PROCESSING
There are line FIFOs on each SDI video input, feeding 2 Video Channel
Blocks (Program and Preview) and one parallel Audio Processing block.
Each video channel has and AB Mix and 4 keyers which may be fed from up
to 3 external Fill/Keys or one of 4 internal stores and an optional dual-
channel DVE.
Still (.oxt), animated and Easytext (.oxa) images are typically stored in the
unit's storage library (compact flash or hard disk, depending upon the option
purchased) and then loaded into the internal stores. Images may be added to
the library using a USB stick but the files must be in an appropriate format.
Miranda Technologies Inc.'s Media Conversion Software is designed for this
purpose and is supplied with each Imagestore 750.
An Ethernet interface provides for the rapid loading of images and
animations over a 100BaseT network using Media Conversion Software
