SYSTEM FOR RECEIVING BROADCAST DIGITAL DATA COMPRISING A MASTER DIGITAL TERMINAL, AND AT LEAST ONE SLAVE DIGITAL TERMINAL

摘要

A system for receiving broadcast digital data (particularly payment television services) is connected to the master terminal by means of a master digital terminal 1 and a link 3 and can receive protected digital data. It includes at least one slave terminal (2). The slave digital terminal can access the protected data only if the information received by the master digital terminal and necessary for accessing the data is transmitted via the link 3 to the slave digital terminal within a predetermined deadline. In particular, this information is the key to descrambling the service or access entitlement to the television service. ; Broadcast digital data receiving system, master digital terminal, slave digital terminal, security code, encryption, decryption
