Abstract: A method for distributing radio band signals between stations in a broadband structure. Radio band signals transmitted from a first station are converted to intermediate signals for transfer through a wire connection while maintaining code structure and modulation of the radio signals. The intermediate signals transferred over the wire connection are received and converted to radio band signals while maintaining code structure and modulation of the radio signals. A system and a method for transmitting radio signals in a broadband structure including a first network, said first network operating on air as a first medium. Said first network is connected to a second network through a first media converting means for converting the radio signals for transfer through the second network, said second network operating on wire as a second medium.

Abstract: In a system for jamming television programs in a cable television system, modified oscillators are used to provide jamming signals to control ports where they are added to the video signal, in order to prevent unauthorized viewing. The oscillators have switchable portions so that they, when receiving appropriate control signals from a control unit on control lines, can be switched to different basic oscillation frequencies and thus each one can cover a very wide frequency range. The basic oscillation frequency of the oscillators is finely adjusted by means of a continuous signal on a line like the conventional voltage control of oscillators. The use of such switched oscillators in an interdiction apparatus for a cable television system provides a number of advantages, such as making the system more flexible and more efficient in terms of jamming capacity for more expensive programs, pay channels, needed oscillator circuitry, etc.
