Patent ID: 7831046

Claim:
A method of managing a display of events with conditional access, the method comprising: sending data forming an electronic program guide (EPG) to a decoder, the EPG displaying a list of events being broadcast, the data for the list of events including, for each event of the list of events, at least one identifier, textual data and a condition block, the condition block including conditions required for accessing the event, sending at least one authorization message to a security module associated with the decoder, the at least one authorization message defining access rights to the event, wherein the access conditions contained in the condition block are expressed in a form of an operation described by a request in a structured language, the operation based on at least two parameters, a first parameter of the at least two parameters being directly linked to the event or to a channel on which the event is broadcast and a second parameter of the at least two parameters being independent of the event or of a channel on which the event is broadcast; and a structured language motor seeks, in the security module, the operation contained in the condition block, and the structured language motor executes the operation, wherein said execution uses at least said first parameter that is directly linked to the event or to the channel on which the event is broadcast and said second parameter independent of the event of the event or of the channel on which the event is broadcast, the execution of said operation resulting in a grant or a denial of an access right, depending on both first and second parameters; returning to the decoder a result of the execution; and displaying the list of events in the EPG based on the execution result of the operation and identifying a displayed event from another displayed event in the list of events based on the access rights.
