Abstract

UN CODIFICADOR/DECODIFICADOR DE TELEVISION DE ALTA DEFINICION COMPRENDE UN NUMERO DE SUBDECODIFACODRES CODIFICADORES PARALELOS. LA IMAGEN A CODIFICAR O DECODIFICAR SE DIVIDE EN NUMEROS DE TIRAS, SIENDO UNA TIRA DADA CODIFICADA O DECODIFICADA POR UNA UNICO SUBDECODIFCADOR O SUBCODIFICADOR. CADA TIRA N SE CODIFICA O DECODIFICA POR EL MISMO SUCODIFICADOR/SUBDECODIFICADOR, DONDE N ES EL NUMERO DE SUBCODIFICADORES IO SUBDECODIFICADORES. EL NUMERO DE SUBCODIFICADORES ES INDEPENDIENTE DEL NUMERO DE SUBDECODIFICADORES CON LO QUE UNA REDUCCION EN EL NUMERO DE SUBCODIFICADORES CON EL INCREMENTO DE LA CAPACIDAD DE BIVELOCIDAD NO NECESITA UN CAMBIO DE DECODIFICADOR.
