Abstract
A system for converting digital signals in a cable network is provided. A cable head end provides a plurality of digital signals. The plurality of digital signals are grouped into a first portion and a second portion, the first portion being in a first frequency band and the second portion being in a second frequency band. The system includes a digital channel remapping module configured to select one or more digital signals from the first portion and remap the selected one or more digital signals into a first plurality of analog signals and a digital-to-analog translator configured to convert the digital signals in the second portion to a second plurality of analog signals. The first and second plurality of analog signals are combined and delivered to at least one analog device. Some or all of the second plurality of analog signals are within the first frequency band.
