1.1. OVERVIEW
The Evertz 7725DSK-LG/7725DSK-LG-HD Downstream Keyer and Logo Inserter is a complete
package that will insert simultaneous static or animated logos over a full bandwidth HD/SD program
video signal. The 7725DSK-LG has been designed to manage and store multiple logo objects. Logos
are stored in non-volatile Flash memory and may be downloaded to the hardware via an RS-232 serial
interface or via Ethernet FTP using the Overture™ software. The 7725DSK-LG has a key and fill input
to allow for external keyer sources. It supports two video input sources and preview and program bus
outputs.
In addition to the support for an external keyer, one animated logo or up to 16 static logos can be
keyed simultaneously with independent fade control for each static logo. The size of each logo varies
and ranges from 1/25th to full screen. The position of the logo, fade rates, clip association and
animation rates are also user controllable. The 7725DSK-LG comes with 192MB of playout cache and
1GB compact flash storage.
The onboard preview allows you to cue your logos for position and content verification prior to going
"On Air". Audio clips are stored as stereo 16-bit, 48kHz WAV format. The optional features of the
7725DSK-LG are: a crawl option that provides the ability to insert crawls with static content and an
interface for Emergency Alert Systems (EAS).
