Abstract
PARA FABRICAR UN SISTEMA DE TRANSMISION COMPATIBLE NORMAL Y COMPATIBLE CON LAS NORMAS, DONDE SE ANALIZA LA FUENTE DE LA IMAGEN LATERAL CON UN RETICULO CORRESPONDIENTE A UNA RELACION LATERAL DE LA IMAGEN AGRANDADA DE 16:9, SE SEPARA PRIMERAMENTE PARTIENDO DEL LADO DE LA EMISORA, CADA CUATRO RENGLONES DE LA SEÑAL DE IMAGEN Y SE COMPRIMEN DE FORMA ESPACIAL LOS TIEMPOS QUE HAN QUEDADO. EN LAS HABITACIONES ESPACIALES QUE QUEDAN LIBRES SE AÑADEN LOS CUATRO RENGLONES SEPARADOS EN EL BORDE DE LA IMAGEN SUPERIOR E INFERIOR Y, DADO EL CASO, EN FORMA CENTRIFUGA. LA SEÑAL DE IMAGEN RESULTANTE SE TRANSMITE DE FORMA CODIFICADA. DE LA SEÑAL DE IMAGEN DESCODIFICADA Y EMITIDA SE RECONSTRUYE LA SEÑAL DE IMAGEN ORIGINAL CON UNA RELACION LATERAL DE LA IMAGEN DE 16:9, DE TAL FORMA QUE SE INTRODUCEN LOS CUATRO RENGLONES AÑADIDOS EN LA PARTE SUPERIOR E INFERIOR DE LA SEÑAL DE IMAGEN O DADO EL CASO, SEGUN EL PROYECTO REALIZADO DE FORMA CONSECUTIVA EN LOS OTROS RENGLONES DESCOMPRIMIDOS Y ESPACIALES. EL SISTEMA ES PARA APARATOS DE TRANSMISION CON UN FORMATO DE IMAGEN DE 4:3, ASI COMO DE FORMATOS DE IMAGEN AMPLIADOS 16:9.
