Abstract

La invencion se relaciona con un metodo para ordenar imagenes codificadas, el metodo consiste de una etapa de codificacion para formar imagenes codificadas en un codificador. Se forma por lo menos un grupo de imagenes de las imagenes y para cada imagen del grupo de imagenes se swdine un ID de imagen. En el metodo se realiza una etapa de transmision para transmitir las imagenes codificadas a un descodificador. Las imagenes codificadas se rearreglan en orden descodificante y se descodifican para formar imagenes descodificadas. En la etapa de codificacion se define para las imagenes codificadas una ID de secuencia de video separada de la ID de imagen para las imagenes codificadas, la ID de secuencia de video es la misma para cada imagen del mismo grupo de imagenes. En la etapa de descodificacion se utiliza la ID de secuencia de video para determinar cuales imagenes pertenecen al mismo grupo de imagenes. La invencion tambien se relaciona con un sistema, codificador, descodificador, dispositivo electronico, programa de software y un medio de almacenamiento.
