Abstract

UNA ESTRUCTURA DE DATOS DE UNA SEÑAL DE IMAGEN QUE INCLUYE UN IDENTIFICADOR DE CICLO DE REPRODUCCION, INDICANDO SI EL CICLO O VISUALIZACION DE LA IMAGEN PARA CADA TRAMA ES VARIABLE O NO. CUANDO EL IDENTIFICADOR DE CICLO DE VISUALIZACION INDICA QUE EL CICLO DE VISUALIZACION ES FIJO, SE INSERTAN DATOS DEL CICLO DE VISUALIZACION EN UN ENCABEZADO DE LOS DATOS DE LA IMAGEN CODIFICADA, Y LOS DATOS RELATIVOS AL NUMERO DE TRAMAS ES INSERTADO EN CADA TRAMA. POR EL CONTRARIO, CUANDO EL IDENTIFICADOR DEL CICLO DE VISUALIZACION INDICA QUE EL CICLO DE VISUALIZACION ES VARIABLE, LOS DATOS DEL TIEMPO DE VISUALIZACION SE INSERTA PARA CADA TRAMA. EN CONSECUENCIA, AL DECODIFICAR Y VISUALIZAR LOS DATOS DE LA IMAGEN CODIFICADA QUE TENGA UN CICLO DE VISUALIZACION FIJO, LOS DATOS DE LA IMAGEN CODIFICADA PUEDEN SER VISUALIZADOS MEDIANTE UNA ESTRUCTURA CIRCUITAL SENCILLA, ES DECIR, BASANDOSE EN LOS DATOS DEL CICLO DE VISUALIZACION Y LOS DATOS DEL NUMERO DE TRAMAS QUE TENGAN UNA CANTIDAD DE DATOS RELATIVAMENTE PEQUEÑA (NUMERO DE BITS), SIN REFERIRSE A LOS DATOS DEL TIEMPO DE VISUALIZACION QUE TENGAN UNA CANTIDAD DE DATOS RELATIVAMENTE GRANDE PARA CADA TRAMA. ADICIONALMENTE, ESTA ESTRUCTURA DE DATOS PUEDE SER APLICADA A UNA SEÑAL DE IMAGEN CODIFICADA QUE TENGA UN CICLO DE VISUALIZACION VARIABLE.
