SOUTH PLAINFIELD, N.J. -- In response to market demand, Radiant Communications introduced the QRF5000, the first in a series of QAM channel inserters. The single rack-unit device encodes local baseband video and audio channels into quadrature amplitude modulation (QAM) signals via a built-in modulator enabling cable operators to rapidly and cost effectively deploy all-digital lineups to low-cost digital set-top units.

Radiant’s QRF5000’s flexible architecture is designed to support changing network demands. Users can select bit rates ranging from 32 kbps to 44.8 kbps, configure four different PID values from 30 to 8192, and output either 64 or 256 QAM signals for television channels 7 to 137. The innovative channel inserter supports eight different audio settings and allows operators to set values for video resolution from full D1 to ½ D1 in four incremental steps. With a password-protected front panel controller, the plug and play device is remotely configurable and features built-in SNMP for status monitoring. In addition, operators can use the QRF5000 to encode 12 or more local channels with Radiant’s QRF5010 expansion module.

“A number of MSOs asked Radiant to develop a solution that would cost effectively convert analog channels into digital signals for digital simulcast. Radiant’s QRF5000 delivers and is affordable for systems of all sizes, including those serving small subscriber counts,” said Lou Nagorsky, Radiant Communications’ national sales manager.

The QRF5000 has been designed and tested to work with current and legacy cable boxes. It is suitable for a variety of applications, including security cameras for gated communities, multiple dwelling units (MDUs), hotels and condominium complexes; informational bulletin boards; public, educational, and government access (PEG) television; and any application where video and audio feeds need to be viewed within the digital lineup. The device is especially useful in hotel applications, where it enables easy integration of convention television channels while simultaneously showing local system programming.
