Abstract:
1. A return path transmitter for use in conjunction with a local system that generates an analog RF data signal to be conveyed to a head end system, the return path transmitter comprising: an RF signal receiver configured to receive and convert the analog RF data signal into digitized RF data samples, the RF signal receiver further configured to output a first data stream including the digitized RF data samples; digital processing circuitry configured to digitally process the first data stream and create corresponding digitally processed data; a summing circuit configured to sum the corresponding digitally processed data of the first data stream to create a combined digital data stream; an optical transmitter configured to convert the combined digital data stream into a first optical data signal for transmission over an optical fiber to the head end system; and means for receiving commands originating from the head end system, said commands sent in response to the corresponding digitally processed data, wherein said commands when executed adjust an operation of the digital processing circuitry.
