Abstract
APARATO DE COMPRESION DE SEÑAL DE VIDEO QUE INCLUYE UNA MEMORIA (12, 14) PARA ALMACENAR DOS CAMPOS DE DATOS DE IMAGEN Y PROPORCIONAR CAMPOS DE DATOS DE IMAGEN SEPARADOS POR INTERVALOS DE IMAGEN. LOS DATOS DE IMAGEN DE UNO DE LOS CAMPOS CORRESPONDIENTES DE SUCESIVAS IMAGENES SE RESTAN (16) PARA GENERAR DIFERENCIAS DE CAMPO. LAS DIFERENCIAS DE CAMPO SE ACUMULAN (18) SOBRE LOS INTERVALOS DE CAMPO RESPECTIVOS, Y LA SUMA SE COMPARA (20) CON UN VALOR PREDETERMINADO. SI UNA SUMA DE DIFERENCIAS SOBRE UN CAMPO ES MENOR QUE EL VALOR PREDETERMINADO, EL CAMPO MAS RECIENTE SE CONSIDERA QUE VA A SER REDUNDANTE Y PUEDE SER CORTADO. DESPUES DE QUE LOS RESPECTIVOS CAMPOS SE CORTAN (21), SE COMPONEN (25) IMAGENES DE SEÑAL DE VIDEO A PARTIR DE LOS CAMPOS RESTANTES. LOS TIPOS DE CAMPO (POR EJEMPLO PAR O IMPAR) DE LOS CAMPOS EN LA MEMORIA SON DETERMINADOS (11), Y SE ACCEDE A LOS DATOS DESDE LOS RESPECTIVOS CAMPOS EN MEMORIA DE MODO QUE LOS DATOS DE LOS CAMPOS PARES O IMPARES OCUPEN LINEAS PARES O IMPARES EN LASIMAGENES COMPUESTAS RESPECTIVAMENTE. SE ASOCIAN BANDERAS (DF, DT) CON LAS IMAGENES COMPUESTAS PARA INDICAR QUE CAMPOS CONTIENEN DATOS ASOCIADOS CON LOS CAMPOS CORTADOS, Y QUE CAMPO DE LAS IMAGENES COMPUESTAS SE VISUALIZARA PRIMERO.
