ABSTRACT:
A method that allows the optimization of the consumption of conditional access content in order to guarantee less vulnerable right messages involves three steps: the selection by the user of a content and the indication of this interest to said management center; the sending of a notification message containing or indicating the access authorisation message shortly before the broadcast of said content and storage of this authorisation message; and the sending of the content itself and the use of the data of the authorisation message in order to access the data of the content. There may be a fourth stage, namely the validation of the authorisation message by the user. This validation is executed in general at the time of the reception of the content or alternatively the user confirms their intention to purchase.
