Abstract
A video signal transceiver has a triax port, a baseband port, a demodulator for converting a HF video signal received at said triax port into a baseband video signal for outputting at said baseband port and at least one modulator for converting a baseband control signal received at said baseband port into a HF control signal for outputting at said triax port, a fibre-optical port, an optical receiver for converting an optical video signal received at said fibre-optical port into a baseband video signal, a switch for connecting either an output of said demodulator or of said optical receiver to a video signal line of said baseband port, and an optical transmitter for transmitting, via said fibre-optical port, an optical control signal derived from said baseband control signal.
Claims19
A video signal transceiver having a triax port, a baseband port, a demodulator for converting a HF video signal received at said triax port into a first baseband video signal for outputting at said baseband port and at least one modulator for converting a baseband control signal received at said baseband port into a HF control signal for outputting at said triax port, a fibre-optical port, an optical receiver for converting an optical video signal received at said fibre-optical port into a second baseband video signal, a switch for connecting either said first baseband video signal or said second baseband video signal to a video signal line of said baseband port, and an optical transmitter for transmitting, via said fibre-optical port, an optical control signal derived from said baseband control signal.
A video signal transceiver having a baseband port, a triax port, a modulator for converting a baseband video signal received at said baseband port, into a HF video signal for outputting at said triax port and a filter for converting a HF control signal received at said triax port into a first baseband control signal for outputting at said baseband port, a fibre-optical port, an optical transmitter for converting a baseband video signal received at said baseband port into an optical video signal for transmission at said fibre-optical port, an optical receiver for converting an optical control signal received via said fibre-optical port into a second baseband control signal, and a switch for selectively connecting either the first baseband control signal or said second baseband control signal derived from said optical control signal by said optical receiver to at least one demodulator, and said at least one demodulator for converting said output of said switch into a control signal supplied to a control signal line of said baseband port.
