Abstract

SEÑALES DE VIDEO DIGITAL SE COMPRIMEN CON ADAPTACION PARA COMUNICARLAS A UN RECEPTOR. SUPERBLOQUES (230), CADA UNO CONTENIENDO UNA PLURALIDAD DE BLOQUES DE DATOS (232) DE VIDEO DIGITAL, SE COMPRIMEN USANDO PCM, DPCM CON UN VECTOR DE MOVIMIENTO GENERAL PARA EL SUPERBLOQUE COMPLETO Y DPCM CON UN VECTOR DE MOVIMIENTO ESPECIFICO PARA CADA BLOQUE CONTENIDO DENTRO DE UN SUPERBLOQUE. EL RESULTADO DE CADA MODO DE COMPRESION SE COMPARA (58) DESPUES DE DAR CUENTA DE LOS DATOS SUPERPUESTOS, PARA DETERMINAR QUE RESULTA EN LA MINIMA CANTIDAD DE DATOS PARA CADA BLOQUE (232). ESTOS BLOQUES ESTAN ENSAMBLADOS EN UN SUPERBLOQUE (230), Y COMPARADOS (80) EN CONJUNTO CON LOS DATOS DEL VECTOR DE MOVIMIENTO Y DE SUPERPOSICION NECESARIOS PARA EL MISMO SUPERBLOQUE PROCESADO USANDO TODOS PCM TAN BIEN COMO E SUPERBLOQUE PROCESADO USANDO TODOS DPCM. LA COMPARACION DETERMINA QUE MODO DE COMPRESION PRODUCE LA MENOR CANTIDAD DE DATOS PARA EL SUPERBLOQUE. EL SUPERBLOQUE MAS COMPACTO SE SELECCIONA POR TRANSMISION. LOS SUPERBLOQUES TRANSMITIDOS SE DECODIFICAN POR MEDIO DE UN DECODIFICADOR (FIG. 5) QUE RECUPERA LOS VECTORES DE MOVIMIENTO NECESARIOS Y LA INFORMACION SUPERPUESTA QUE IDENTIFICA EL TIPO DE COMPRENSION USADA PARA SUMINISTRAR EL SUPERBLOQUE.
