ABSTRACT:
Apparatus for transmitting camera control characteristic information from a central unit to a remote television camera by superimposing a series of pulse-position modulated (PPM) signals onto a black burst signal which includes transmitted synchronization signals, each PPM coded signal representing the value of a corresponding control characteristic. Specifically, between adjacent horizontal synchronization pulses which are outside vertical blanking intervals, a predefined sequence of time windows is provided and a pulse is positioned in each window. The window corresponds to a given control characteristic and the position of the pulse within the window represents the value of the given control characteristic.
