Abstract
Remotely switchable signal source modules are mounted to a cable television converter to enable a viewer to select between alternate television signal sources. Power for the module is provided via the converter's RF input terminal, which mates with a corresponding terminal on the module. An RF bypass module enables the viewer to utilize the features of a cable ready television when connected to a cable television network. Simultaneous viewing and recording of different channels can also be accommodated. An input A/B switch module enables the viewer to select between alternate cable system inputs. An output A/B switch module provides compliance with FCC requirements permitting viewing of off-the-air channels not carried on a cable system.
