Abstract
An endoscopic television system includes: a character generator which is controlled by a keyboard to store characters selected by actuation of the keyboard in a character store; an image control trigger by synchronization pulses derived from an endoscopic image video signal to read out the stored characters in the character store and to generate a character video signal; a mixer for mixing the endoscopic image video signal and the character video signal to generate a composite signal that is supplied to a television monitor. The characters are displayed on the television monitor in the portion of the screen not occupied by the endoscopic image.
