Abstract

APARATO PARA CODIFICAR UNA SEÑAL DE VIDEO EN QUE UNA SEÑAL DE TELEVISION DE PANTALLA ANCHA, QUE TIENE INFORMACION DE PANELES LATERAL IZQUIERDO, LATERAL DERECHO Y CENTRAL, ES CONVERTIDA EN UNA SEÑAL COMPATIBLE CON UN SISTEMA DE TELEVISION NORMAL, TAL COMO NTSC. EN LA SEÑAL COMPATIBLE, LA INFORMACION DE PANEL CENTRAL ES EXPANDIDA PARA OCUPAR LA REGION DE PRESENTCION NORMAL VISTA POR UN OBSERVADOR, LA INFORMACION DE BAJA FRECUENCIA DE LOS PANELES LATERALES ES COMPRIMIDA HACIA LA REGION DE SOBREBARRIDO HORIZONTAL, Y LA INFORMACION DE ALTA FRECUENCIA DE PANELES LATERALES MODULA UNA SUBPORTADORA SUPLENTE DISTINTA DE LA SUBPORTADORA DE CROMINANCIA. LA SUBPORTADORA SUPLENTE ESTA A UN FRECUENCIA DE ENTRELAZAMIENTO QUE ES UN MULTIPLO IMPAR DE LA MITAD DE LA VELOCIDAD DE LINEAS HORIZONTALES, Y ESTA SITUADA ENTRE LA BANDA DE DETALLE VERTICAL DE LUMINANCIA Y LA BANDA DE CROMINANCIA.
