Abstract

UN SISTEMA DE PROCESAMIENTO DE SEÑALES DE VIDEO DIGITAL QUE INCLUYE UN APARATO PARA OCULTAR LOS ERRORES QUE PUDIERA HABER EN LAS IMAGENES REPRODUCIDAS DEBIDO A UNA PERDIDA DE LOS DATOS DE IMAGEN DURANTE LA TRANSMISION DE LA SEÑAL. EL SISTEMA INCLUYE UN CIRCUITO PARA DETECTAR LOS DATOS DE VIDEO TRANSMITIDOS (20-24), GENERAR SEÑALES DE ERROR SI HUBIERA ERRORES EN LOS SEGMENTOS (BLOQUES DE TRANSPORTE) DEL DATO RECIBIDO (25) Y SUPRIMIR LOS SEGMENTOS CON ERRORES DEL FLUJO DE DATOS. EL ENVIA EL DATO RECIBIDO A UN SISTEMA DECODIFICADOR/DESCOMPRESOR (26, 27) QUE DECODIFICA Y DESCOMPRIME EL DATO DE VIDEO RECIBIDO SIGUIENDO UNA SECUENCIA PREDETERMINADA. EL DATO DE VIDEO DESCOMPRIMIDO SE PUEDE ENVIAR A UNA MEMORIA (318) PARA DESPUES PODER VISUALIZARLO, REGISTRARLO, ETC. EL DESCOMPRESOR RESPONDE A LAS SEÑALES DE ERROR PARA ALTERAR LA SECUENCIA PREDETERMINADA.
