®
family of set-tops) and the D9482 DAVIC
QPSK Modulator to provide a forward signaling and
reverse path communications for interactive video and
data systems over a conventional two-way CATV
network. Combined, the D9492 QPSK Demodulater and
D9482 QPSK Modulator create a DAVIC-compliant
headend QPSK signaling hub.
