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.
IP Data Output
IP data can be received and output at rates up to 50 Mbps.
