Abstract

Un controlador de sistema de vídeo (200) inserta impulsos de sincronizacion en una línea de cámara de video (100), que crea un cuadro de video en la línea de cámara de video. El controlador de sistema de video inserte también un codigo de cámara en el periodo activo de video de una línea no vista del cuadro de video. Una pluralidad de unidades de cámara (301-304) están conectados a la línea de cámara de video y usan los impulsos de sincronizacion colocados en la línea de cámara de video para permanecer sincronizados con las demás unidades de cámaras. Al detectar un codigo de cámara particular en la línea de cámara de video, la unidad de cámara que corresponde al codigo de cámara particular, inserta una señal de imagen de video en el periodo de tiempo de video activo de la línea de video para el cuadro de video que contiene el codigo de cámara particular. El codigo de cámara de video regresa el controlador de sistema de video que recibe el cuadro de video que contiene un compuesto de los impusos de sincronizacion provenientes del controlador de sistema de video y la señal de imagen de video. El controlador de sistema de video transmite después una señal de imágen de video a una videograbadora o bien dispositivo de visualizacion de video (400).
