Abstract
An opto-electronic selector having matrix-addressed photodetectors is characterized in that the photodetectors (Ph) are followed by individual amplifiers (PA), each of which is powered at constant voltage by a voltage source under the control of a matrix line selection control (X) and at constant current from a current source proper to said amplifier and capable of being switched on under the control of a matrix column selection (Y), thereby forming a switching cell (C) in conjunction with the associated photodetector. Such a detector may be used in broadcasting programs to subscribers.
