Abstract
A method of operating a communications system storing assets for later transmission, is disclosed. The assets have respective expiration dates beyond which a right to transmit expires. The method comprises checking an expiration date of an asset and deleting the asset from storage based, at least in part, on the expiration date, a predetermined period of time added to or subtracted from the expiration date and/or whether the asset has been selected for later viewing. The predetermined period of time may provide a grace period for completing viewing of a selected asset by a user, either after or before the expiration date, depending on the rights to the asset granted by the source of the asset. The period of time may depend on a playtime of the asset and may be added to the expiration date only if the asset has been selected for viewing. Systems are also disclosed.
