ABSTRACT:
A CATV/MDS set top converter installation process is performed at the installation site without access to any internal components of the converter. The process is performed in two stages. In the first stage, the converter is pre-programmed with a first set of proprietary data by the installer using a hand held IR transmitter. In the second stage, the converter is addressed over-the-air by the addressing computer at the head end of the system to program the converter with a second set of proprietary data.
