Abstract: Bandwidth limitations in some video systems (e.g., those employing telephone transmission lines) prohibit the transmission of high-resolution video with the normal frame interval. One proposal for overcoming this is to extend the frame period. Although moving subjects cannot be televised in this way the proposal is quite adequate for transmitting documents. The convenient way to implement this proposal is to use a slow scan rate in the camera. However, conventional cameras are not made with sufficient storage duration to allow slow scan rates. The specification describes a video camera with a novel mode of operation to give extended storage capability.
