EH244 ENCODER HOST SERIES
Each encoder output can be disabled or output to any or all out-
put channels
All programs directed to each output are multiplexed into a cor-
rect multi-program transport stream
An optional 4 ASI Output board may be ordered that mirrors the
4 QAM channel output transport streams
