Abstract

Se describen métodos y aparatos para codificar datos multimedia que posibilitan, entre otros, por ejemplo, calidad mejorada de video decodificado, capacidades mejoradas de recuperacion de error y/o eficacia mejorada de la decodificacion. Un dispositivo codificador determina uno o más valores de distorsion para uno o más porciones de datos multimedia basado al menos en parte en uno o más métodos de ocultamiento relacionados con ocultar las una o más porciones si una o más porciones fueron recibidas por error. El dispositivo de codificacion determina uno o más métodos de codificacion para las una o más porciones basado al menos en parte en uno o más valores de distorsion estimados. En un aspecto, determinar los uno o más métodos de codificacion comprende determinar los uno o más métodos de codificacion para renovar las una o más porciones basado al menos en parte en una comparacion de los uno o más valores de distorsion estimados y uno o mas umbrales.
