7725DSK-LG & 7725DSK-LG-HD

HD/SD Downstream Keyer and Logo Inserter

VistaLINK® enabled Overture enabled Active Format Descriptor (AFD)

The 7725DSK-LG-HD Downstream Keyer and Logo Inserter is a complete package that will insert simultaneous static or animated logos over a full bandwidth SDI program video signal.

The 7725DSK-LG (SDI only) 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 Ethernet FTP using the Overture™ software. The 7725DSK-LG-HD has a key and fill input to allow for external keyer sources.

In addition to the support for another 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 is variable and ranges from 1/25th to full screen. The position of the logo, fade rates, and animation rates are also user controllable. The 7725DSK-LG-HD comes with 384MB of playout cache and 1GB of compact flash storage.

The onboard preview allows you to cue your logos for position and content verification prior to going "On Air". The optional features of the 7725DSK-LG-HD are an air temperature probe and a crawl option which provides the ability to insert crawls with static content.
