Abstract

La presente invencion proporciona un aparato de grabacion de transmisiones digitales que puede evitar grabaciones innecesarias en situaciones en las que la desaleatorizacion no sea posible o sea prohibida durante la grabacion de video aleatorizado. El aparato de grabacion de transmisiones digitales incluye: una unidad de juicio de desaleatorizacion (515) que detecta un canal en donde ocurre una situacion de desaleatorizacion no posible, y un administrador de servicios (1204) que concluye la grabacion y escribe, en una tabla de administracion, que ha ocurrido una situacion de desaleatorizacion no posible durante la grabacion, cuando hay datos de grabacion que muestran que la grabacion esta siendo ejecutada en el canal que se detecto como teniendo la situacion de desaleatorizacion no posible.
