摘要： A method of upstream communication over a linear broadband network includes the steps of generating an upstream baseband signal and modulating it onto an upstream wireless radio frequency carrier to produce a first upstream modulated carrier signal. The modulated carrier signal is transmitted wirelessly, received, and demodulated to reproduce the information integrity of the upstream baseband signal. The signal is then modulated onto an upstream linear broadband radio frequency carrier for transmission on the linear broadband network. Advantageously, noise that accumulates at the subscriber premises is removed from the upstream signal prior to presentation of the signal to the upstream path of the linear broadband network. A system for communicating over a linear broadband network includes network access interface devices coupled to the linear broadband network. A subscriber access interface device accepts upstream communication signals and modulates and transmits the signal to the network access interface device. The network access interface device 6 receives and demodulates the signal and then modulates it for transmission on the linear broadband network.

摘要： A television signal converter includes ON/OFF means and channel selection means responsive to remotely transmitted infra-red command signals. The signal channel frequency output of the converter is coupled to the input of a VCR having program means enabling a user to determine a recording time schedule. A microprocessor driven programmable remote command signal transmitter supplied ON/OFF and channel selection command signals to the converter.

摘要： An image enhancement system for television wherein conventionally generated detail signals representative of variations in the amplitude of the video signal are further processed before being added to the video signal. A first fractional amplitude portion of the generated detail signal is amplified and then subjected to severe coring and the resulting bi-polar signal is combined with a second fractional amplitude portion of the generated detail signal to produce a resultant detail signal having a contour which reduces the width of the edging effect at contrast transitions associated with conventional enhancement systems, and in which high frequency noise and other spurious signals are substantially reduced while retaining fine detail to enhance key parts of the television picture.
