Abstract

Método de diversidad de lugares para continuar una emisión digital por satélite por intercambio de lugar, caracterizado porque cuando se recibe una señal de designación de la ejecución de cambio de lugar, el lugar es cambiado para continuar la emisión durante un período de un campo de información TMCC en un marco específico predeterminado en un supermarco determinado en un punto de tiempo cuando se recibe la señal de designación de ejecución.
