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.
Claims25
A cable television radio frequency data processor for use in a two-way cable television system in which television services are provided in a forward direction and data is returned in a reverse direction between a headend including a system manager and a plurality of television terminals, the television terminals adapted to return redundant data on a plurality of channels, the cable television radio frequency data processor comprising:
- a plurality of data receivers for receiving the returned data on the plurality of channels;
- detector means coupled to the data receivers for providing an indication of received signal level on the plurality of channels;
- and
- data processing means coupled to the data receivers for eliminating redundant data and coupled to the detector means for collecting data on received signal level on the plurality of channels.
A cable television radio frequency data processor for use in a two-way cable television system in which television services are provided in a forward direction and data is returned in a reverse direction between a headend including a system manager and a plurality of television terminals, the television terminals adapted to return redundant data on a plurality of channels, the cable television radio frequency data processor comprising:
- a plurality of data receivers for receiving the returned data on the plurality of channels;
- and
- data processing means coupled to the data receivers including means for evaluating the returned data for error, means for eliminating redundant data, and means for collecting statistical data on data throughput of the plurality of channels.
A cable television radio frequency data processor for use in a two-way cable television system in which television services are provided in a forward direction and data is returned in a reverse direction between a headend including a system manager and a plurality of television terminals, the television terminals adapted to return redundant data on a plurality of channels, the cable television radio frequency data processor comprising:
- a plurality of data receivers for receiving the returned data on the plurality of channels;
- a communications interface coupled to the system manager;
- and
- data processing means coupled to the communications interface and to the data receivers for eliminating redundant data from the returned data on the plurality of channels and for output of the returned data via the communications interface to the system manger.
