Abstract
EN EL SISTEMA QUE SE PRESENTA, LA EXPLORACION SE LLEVA A CABO EN EL LUGAR DE LA FUENTE VIRTUAL CON UN MACO CORRESPONDIENTE A UN FORMATO DE LA IMAGEN 16:9 ALARGADO. EN EL LUGAR EMISOR, CADA CUARTA LINEA DE LA SEÑAL DE IMAGEN SE AISLA PRIMERO Y LAS LINEAS RESTANTES SE COMPRIMEN. UN RECEPTOR ESTANDAR 4:3 REPRODUCE UNA IMAGEN CORRESPONDIENTE EN FORMATO "CAJA DE ROTULOS". EL RECEPTOR 16:9 DEBERIA RECONSTRUIR LA SEÑAL DE IMAGEN ORIGINAL. PRIMERA SOLUCION: LAS LINEAS AISLADAS SON INTENSIFICADAS DURANTE EL TIEMPO QUE DURA UNA IMAGEN COMPLETA Y MODULADAS A UNA SEGUNDA FRECUENCIA PORTADORA DE IMAGEN EN EL EXTREMO SUPERIOR DEL CANAL DE TRANSMISION QUE SE ENCUENTRA FUERA DE LA CURVA DE RESONANCIA DE FRECUENCIA INTERMEDIA CONTRASTADA Y SON DESPUES DESMODULADAS, INTENSIFICADAS Y REINTRODUCIDAS EN EL RECEPTOR 16:9. SEGUNDA SOLUCION: LAS SEÑALES DE DIFERENCIA DE LINEA CODIFICADAS ANALOGICAMENTE EN EL NIVEL QUE SE ENCUENTRA ENTRE LOS IMPULSOS DEL NEGRO Y DE SINCRONIZACION SON TRANSMITIDAS EN LOS ESPACIOS LIBERADOS DE LOS BORDES SUPERIOR E INFERIOR DE LA IMAGEN, DESCODIFICADAS EN EL RECEPTOR 16:9 Y REUTILIZADOS. TERCERA SOLUCION: DATOS DIGITALES ADICIONALES, EJ. VECTORES DE MOVIMIENTO, SON TRANSMITIDOS EN LOS ESPACIOS LIBERADOS EN LOS BORDES SUPERIOR E INFERIOR DE LA IMAGEN Y UTILIZADOS POR EL RECEPTOR 16:9 PARA INTERPRETAR LAS LINEAS AUSENTES. APLICACION A LOS APARATOS RECEPTORES DE TELEVISION CON UN FORMATO DE LA IMAGEN 4:3 Y 16:9.
