Abstract
In a broadcast system () each broadcast content item is identified by a broadcast Content Reference Identifier (CRID). In a storage device () with a storage () each broadcast content item is identified by a local CRID. A processor () stores a CRID list that includes for CRIDs an associated validity interval including a starting date and an ending date during which interval the CRID is unique for the content item. When the processor receives () a broadcast CRID, it determines () an initial validity interval for the broadcast CRID. The initial validity interval includes a starting date and an ending date during which interval the broadcast CRID is unique for the broadcast content item. It then determines () whether the initial validity interval overlaps with a validity interval stored in the CRID list for an identical CRID. If there is no overlap it adds () the broadcast CRID to the CRID list.
