Abstract

Se proporcionan un metodo y un aparato para detectar y ocultar los cuadros de referencia y de no referencia. Un decodificador de video incluye un decodificador (110) de entropia, un detector (176) de error y un ocultador (178) de error. El decodificador (110) de entropia es para descomprimir una corriente de bits de video descomprimida que tiene el proposito de tener una velocidad fija de cuadro y analizar la corriente de bits de video descomprimida para encontrar las cuentas del orden de imagen para los cuadros de la corriente de bits de video descomprimida. El detector (176) de error es para determinar que un cuadro particular de la corriente de bits de video descomprimida esta faltando con base en las cuentas de orden de imagen. El ocultador (178) de error es para ocultar el cuadro particular. El metodo se logra al descomprimir y analizar la corriente de bits de video para encontrar las cuentas de orden de imagen para los cuadros de la corriente de bits de video descomprimida y despues determinar (224, 228) que un cuadro particular de la corriente de bits de video descomprimida esta faltando con base en la comparacion de las cuentas del orden de imagen y despues ocultar (244) el cuadro particular.
