Abstract
A cable television radio frequency data processor for receiving and processing data transmitted from a cable television terminal to the headend of a cable television system comprises a plurality of data receivers for receiving the returned data, detectors associated with each receiver for providing an indication of received signal strength and a data processor. The data processor responsive to the data receivers eliminates redundant data and collects statistics on data throughput and, responsive to the detectors, collects statistics on received signal strength. The data processor then may initiate recalibration of transmit signal levels or an appropriate selection of data transmit channels as required.
