Abstract

PARA LA PRODUCCION COMPATIBLE DE UN FORMATO 16:9 EN UN APARATO STANDARD DE TELEVISION CON FORMATO 4:3 LA INFORMACION DE IMAGEN DE LA RECEPCION 16:9 SE REPRESENTA CON CINTA NEGRA EN EL BORDE DE IMAGEN SUPERIOR E INFERIOR. PARA LA REPRESENTACION LLENA DE FORMATO SOBRE UN RECEPTOR 16:9 SE TRANSMITEN EN LAS TIRAS NEGRAS DE LA TRANSMISION 4:3 COMPATIBLE INFORMACIONES ADICIONALES, QUE PERMITEN LA MEJORA DE LA CALIDAD DE IMAGEN. CON ELLO UN RECEPTOR 16:9 QUE PUEDE DECODIFICAR LA SEÑAL DE TELEVISION EN LA FORMA CORRECTA, NECESITA EL RECONOCIMIENTO CORRESPONDIENTE DEL TIPO DE SEÑAL. PARA EVITAR UNA MODIFICACION O MENOSCABO DE LA OCUPACION DE LOS HUECOS VERTICALES CONOCIDA HASTA AHORA, SE TRANSMITE UNA INFORMACION ADICIONAL DEL TIPO DE SEÑAL EN LA MITAD LIBRE DE LA SEÑAL DE IMAGEN DE LA PRIMERA O ULTIMA LINEA DE IMAGEN ACTIVA DE LA SEÑAL DE TELEVISION.
