Analog Cable Program Distribution
Composite video and balanced audio outputs can be connected to analog modulators for analog cable
distribution. Four mono audio channels or two stereo pairs are available for primary audio programs, as well as
secondary audio programs (SAP). For example, primary program audio could be carried on one of the stereo
pairs, while SAP audio is carried on the other stereo pair.
Digital Cable Program Distribution
Uplink-addressable transport output provides MPEG program streams for digital tier program delivery, so quality
video programs can be distributed efficiently to households equipped with digital set-top boxes.
Digital Program Replacement
Digital program replacement (DPR) allows programmers to transparently switch their primary service to an
alternative service in the digital domain in blackout applications for cable digital tier distribution. This feature
remaps the packet identifier (PID) information from the primary service to an alternate service, allowing
downstream devices to continue to operate seamlessly. This helps make alternative programming available in the
digital tier without operator intervention.
Cable Headend Advertisement Insertion
For flexible advertisement insertion configurations, this receiver provides four types of outputs:
●
Dual-tone multifrequency (DTMF) cue tone
●
Cue trigger support, with eight open collector outputs
●
One programmable contact closure
●
Digital program insertion (DPI) messaging using Asynchronous Serial Interface (ASI) output
Low-Speed Data Output
Asynchronous utility data (up to 38.4 kbps) is available through an RS-232 interface.
