Abstract :
Because the RCA colour television system is operable (although not most conveniently so) with no change in the synchronizing signal from that used for black-and-white transmission, the black-and-white synchronizing signal will first be considered briefly. The operation of the colour system with this signal will then be discussed. Next, one modification to the standard synchronizing signal, which does not affect black-and-white receiver operation, but which simplifies the construction and operation of colour receivers, will be considered. In conclusion, the colour synchronizing problem will be discussed in more detail and the necessary additional equipment or modifications to present equipment at the transmitter will be presented.
