Abstract

EXISTEN CIRCUITOS DE TRANSFORMACION PARA LA REALIZACION DE UNA TRANSFORMACION DE DCT EN 8*8 O 2*(4*8). LA CONMUTACION ENTRE UN DCT 8*8 O 2*(4*8) PUEDE SER REALIZADA MEDIANTE LA ELECCION ADECUADA DEL NIVEL LOGICO DE UNA LINEA DE CONEXION. SON CONOCIDOS CODIFICADORES HIBRIDOS PARA SEÑALES DE IMAGEN QUE PROCESAN BLOQUES DE SEÑALES DE ENTRADA EXPLORADAS PROGRESIVAMENTE UTILIZANDO DCT, BLOQUES DE PUNTOS DE IMAGEN 8*8 SIENDO CODIFICADOS O DECODIFICADOS EN CADA CASO. EN EL CASO DE CONTENIDOS DE IMAGEN DINAMICA, LAS LINEAS PERTENECIENTES A UN CAMPO SON COMBINADAS PARA FORMA UN PRIMER BLOQUE 8*8, Y LAS LINEAS PERTENECIENTES AL SEGUNDO CAMPO CORRESPONDIENTES SON COMBINADAS PARA FORMAR UN SEGUNDO BLOQUE 8*8 A PARTIR DE ESTOS DOS BLOQUES DE PUNTO DE IMAGEN 8*8 SUPERPUESTOS Y CONDUCIDOS EN ESTA FORMA AL CODIFICADOR HIBRIDO. COMO UN RESULTADO DE LA REORGANIZACION DE LAS SEÑALES DE ENTRADA, LA CONMUTACION ENTRE UNA TRANSFORMACION DCT 8*8 Y 2*(4*8) EN EL CODIFICADOR HIBRIDO ES INNECESARIA PARA SEÑALES DE ENTRADA DE INTERLACE, PERO UN DCT 8*8 PUEDE SER REALIZADO DE FORMA VENTAJOSA TAMBIEN PARA UN CONTENIDO DE IMAGEN DINAMICA.
