Abstract

UN DISPOSITIVO RECEPTOR DE SEÑALES DE VIDEO MUESTRA UNA PRIMERA CONEXION DE SALIDA (3), EN LA QUE SOLO PUEDE RECOGERSE UNA SEÑAL DE SINCRONIZACION DE SUPRESION DE IMAGEN CROMATICA (FBAS) O UNA SEÑAL DE SINCRONIZACION DE SUPRESION DE IMAGEN CON UNA SEÑAL CROMATICA, ASI COMO UNA SEGUNDA CONEXION DE SALIDA (5), EN LA QUE SE TRATAN LAS SEÑALES DE COLOR (R, G, B) ASI COMO LAS SEÑALES DE SINCRONIZACION CORRESPONDIENTES. LOS VIDEOGRABADORES (4) SOLO VALORAN NORMALMENTE UNA SEÑAL DE SINCRONIZACION DE SUPRESION DE IMAGEN CON LA INFORMACION CROMATICA CORRESPONDIENTE Y PUEDEN CONECTARSE A LA PRIMERA CONEXION DE SALIDA (3). LOS APARATOS DE TELEVISION (6) VALORAN NORMALMENTE TAMBIEN LAS SEÑALES RGB Y PUEDEN CONECTARSE A LA SEGUNDA CONEXION DE SALIDA (5). MEDIANTE UN DISPOSITIVO DE CONTROL, LA ENTREGA DE SEÑALES EN LA PRIMERA CONEXION DE SALIDA (3) PARA EL VIDEOGRABADOR PUEDE BLOQUEARSE A CAUSA DE UNA IDENTIFICACION GENERADA POR EL LADO DEL EMISOR. POR MEDIO DE ESTO ES POSIBLE REPRESENTAR UNA EMISION CODIFICADA EN EL APARATO DE TELEVISION (6), AUNQUE SU REGISTRO QUEDA BLOQUEADO POR MEDIO DEL VIDEOGRABADOR (4).
