Description
The Wegener Model Unity 4650 Digital Media Receiver/Decoder is a fully DVB-
compliant satellite video IRD. The U4650 receives an L-band RF carrier from an
external LNB (or, if configured as a decoder, accepts ASI transport from a terres-
trial source), extracts the MPEG transport stream, and provides the decompressed
program content to analog audio/video and (optional) digital audio/video outputs.
Features include:
•Control by local user (terminal or front-panel) or remote COMPEL

system
•Download of software application upgrades via satellite (with backup
application storage)
