MeidaCaster Specifications |
|
|
The Avcast MediaCaster is a digitally tuned video modulator that converts any baseband video and audio signal to a user-selected UHF or ultraband CATV channel. The MediaCaster may be tuned to UHF channels 15-30 or CATV/HRC channels 65-80.
The highest channel of two consecutive unused (or filtered) channels is selected on the MediaCaster by rotating the MediaCaster channel select knob.
