Transmission and reception involve the components of a television system that generate, transmit, and utilize the television signal wave form as shown in the block diagram. The scene to be televised is focused by a lens on an image sensor located within the camera. This produces the picture signal, and the synchronization and blanking pulses are then added, establishing the complete composite video wave form. The composite video signal and the sound signal are then imposed on a carrier wave of a specific allocated frequency and transmitted over the air or over a cable network. That is the process in brief; the specific functions of colour television transmitters and receivers are described in more detail in this section.
