Abstract
Se presentan diversas disposiciones para probar la funcionalidad de dispositivo descodificador de video. Puede recibirse una trama de video descodificada por un dispositivo descodificador de video bajo prueba. La trama de video recibida puede segmentarse en una pluralidad de bloques. Un primer valor puede calcularse para un primer bloque de la pluralidad de bloques de la trama de video recibida utilizando valores de pixel de pixeles presentes dentro del primer bloque. El primer valor puede compararse con un primer valor de referencia. El primer valor de referencia puede corresponder a un primer bloque de referencia de una o más tramas de referencia. La funcionalidad del descodificador de video del dispositivo descodificador de video puede determinarse para ser-funcional al menos parcialmente basado en comparar el primer valor con el primer valor de referencia.
