Video Processing in the PC-100 Color Television Camera

The video signal processing that takes place between the Plumbicons ™ and the Encoder in the Philips PC-100 color television camera is described. In this new system all of the video processing is done within the camera head; RF multiplexing of the video signals makes it possible to transmit two signals from the camera head over a new lightweight triaxial cable (one center conductor and two shields) to the camera control unit and one signal in the reverse direction. Monolithic integrated circuits, precision components and modern circuit techniques are used extensively for their advantages in compactness, weight and performance (particularly stability).
