Abstract

SE GENERA UN NUMERO BINARIO REPRESENTATIVO DEL MOVIMIENTO DE LA RED DURANTE EL INTERVALO DE CAMPO DE UNA SEÑAL DE VIDEO ENTRELAZADA A PARTIR DE LA CUAL SE DERIVA UNA SEÑAL DE DIFERENCIA DE CAMPO A CAMPO QUE TIENE UN BIT DE SIGNO Y UN GRUPO DE BITS DE MAGNITUD. LOS BITS DE MAGNITUD SE COMPARA CON UN PRIMER UMBRAL PARA SUMINISTRAR UNA PRIMERA SEÑAL INDICATIVA DEL UMBRAL QUE, CON EL BIT DE SIGNO, SE APLICA POR MEDIO DE LINEAS RESPECTIVAS DE UN BUS A CADA CORRELACCIONADOR DE UN GRUPO DE CINCO CORRELACCIONADORES. LOS CORRELACCIONADORES SON DIRECCIONADOS UTILIZANDO UN DIRECCIONAMIENTO VARIABLE PARA DETECTAR CARACTERISTICAS REPRESENTATIVAS DE MARCOS ORIGINADOS DE UNA PELICULA DE ARRASTRE 2-2 Y DE ARRASTRE 3-2. SE SUMINISTRA UNA LOGICA PARA DETECTAR CUANDO UNO Y SOLAMENTE UNO DE LOS CINCO CORRELACCIONADORES INDICA LA DETECCION DE LA PELICULA PARA VERIFICAR EL MODO DE DIRECCIONAMIENTO DE LA PELICULA. EL ERROR DE REDUCCION SE MEJORA ADICIONALMENTE COMPARANDO LA SEÑAL DE DIFERENCIA DE CAMPO CON UN SEGUNDO UMBRAL, MAYOR QUE EL PRIMERO PARA SUMINISTRAR UNA SEGUNDA SEÑAL INDICATIVA DEL UMBRAL A CADA CORRELACCIONADOR POR MEDIO DE UN SEGUNDO BUS. SE PRODUCEN MARCADORES PARA IDENTIFICAR EL MODO DE FUNCIONAMIENTO DE LA PELICULA Y PARA IDENTIFICAR TAMBIEN CUAL DE LOS DOS CAMPOS ADYACENTES ES ADECUADO PARA SU USO EN UN PROCEDIMIENTO DE VIDEO SUBSECUENTE TAL COMO DESENTRELAZADO O DE REDUCCION DE FLUCTUACIONES.
