General Description
Stradis MPEG-2 Decoders are designed for easy integration into professional MPEG-2
based video systems. These flexible PCI card parses all standard MPEG streams, in all
MPEG video and audio formats. It decodes both high-quality 4:2:2 video and 4:2:0 video
at up to 50 Mbps – placing it at the head of the class in performance – and generates
output in any standard format you require. Additional capabilities include the insertion of
digital audio into the SMPTE 259M video signal, a Genlock input for external
synchronization from a master sync generator, and a proprietary clock-recovery-and-
synchronization circuit that accepts real-time streams from a satellite or terrestrial
network. Stradis Decoders can even display the output on a VGA monitor; a special
burst transfer mode minimizes bus overhead and produces outstanding video.
Stradis MPEG-2 Decoders – Professional performance for world-class applications.
