摘要： A reverse path signaling circuit is described which provides less noise and interruption when injecting signals upstream to a head end. The reverse path signaling circuit includes a low pass filter, a status monitor, and a common emitter amplifier. The common emitter amplifier has a emitter region which couples to the status monitor. The status monitor couples to the common emitter amplifier as a single-ended input to the to the emitter region. The status monitor injects status monitor signals into the emitter region for passing the status monitor signals upstream to a head end. The low pass filter is coupled to another input on the common emitter amplifier. An output from the common emitter amplifier is taken at a collector region. The reverse path signaling circuit of the present invention does not require the use of a directional coupler as part of the circuit. Systems and methods are further included within the scope of the present invention.

摘要： In a cable data system, several frequency division multiplexed upstream data signals on an individual cable can be selectively routed to frequency-selective band pass filters using a relay matrix between the filters and the cable. By appropriately controlling the relays, the upstream information can be split out to as many different filters that might be required to recover the frequency division multiplexed information. Cabling installation to a cable modem termination system is simplified and maintenance costs are reduced by carrying multiple signals on one cable.

摘要： A video-on-demand system transfers a control screen signal to a second communication system and receives a viewer control signal from the second communication system. The video-on-demand system transfers video signals to either a first communication system or the second communication system based on the viewer control signal. The second communication system uses less bandwidth to transfer the video signals than the first communications system. The control screen could be a web page that includes: 1) a video display menu with a selection of displays and bandwidths to display the video signals, 2) a video content menu with a video preview selection, and/or 3) a video display control menu comprising play, pause, rewind, fast forward, and stop. The video-on-demand system implements the control screen menu selections.

摘要： A dual mode tuner/receiver is disclosed in which both analog and digital signals can be received and processed. A low pass filter allows all channels below a selected frequency enter the circuit. A precisely controlled dual conversion circuit creates an intermediate frequency (IF) signal. An automatic carrier detection circuit monitors the IF signal and determines whether the signal is of analog or digital format and intermediate frequency filters are adjusted based upon the type of signal detected. A coherent oscillator circuit generates in-phase and quadrature reference signals that are used by video and audio detectors for further processing of the IF signal. In-phase and quadrature outputs are provided for digital signals and composite video and audio outputs are provided for analog signals.
