MDU ENCODER AND QAM MODULATOR

Installation & Operational Manual

Rev. G2

1. Introduction

The Radiant Communications Corp. QRF5000 series is a highly integrated, technologically advanced family of products used to insert one or more local video feeds into a digital cable system. The QRF5000 series consists of several products which work seamlessly together, or completely independent, to fulfill specific individual requirements in a cost effective, efficient and flexible manner.

QRF5000

Video is encoded with up to four high quality, real time, hardware based, MPEG-2 encoders and audio is encoded using Dolby Digital 2.0 AC3 encoding. The units will encode, and packetize incoming signals and then multiplex them together so that they can be digitally QAM modulated in preparation for final RF agile up-conversion.

QRF5000DQ

The QRF5000DQ contains a digital QAM tuner module, which can be configured to tune to any channel within a standard cable lineup. Once tuned, the user is shown a list of services which are within the digital channel. The users can than select which services to keep, and which services to remove. In conjunction with the up to three installed encoders and external RF Notch Filter, the user can add local video to an existing digital QAM. This allows for maximum bandwidth allocation and provides a path for head end communications to reach a digital QAM tuner in the case where set top boxes are not used. This is important for applications where such signals as E.A.S are required.
