Abstract

An apparatus for testing a video stream received at a subscriber site includes a coupling for receiving broadband RF signals communicated over a hybrid fiber coaxial (HFC) network, a signal level measurement circuit operably coupled to the coupling, the signal level measurement operable to generate signal level measurements regarding a first set of the broadband RF signals received through the coupling, a communication circuit operable to obtain a stream of video data packets from a second set of broadband RF signals received through the coupling, a processing circuit operably connected to the communication circuit, the processing circuit operable to receive signal level measurements from the signal level measurement circuit and to generate diagnostic data corresponding to the second set of broadband RF signals, the processing circuit further operable to communicate information representative of the signal level measurements and the diagnostic data in human-perceptible form. The apparatus may be housed within a portable unit for transportation to subscriber sites throughout an HFC network.
