摘要：The device has a compact memory interface (INT1) connected to a portabledisplay apparatus, where the device resembles a mechanical adapter (AD). An accesscontrol module (SM) has a memory (RM) for storing video flow access rights, and a
cryptographic processing unit for processing secured messages extracted from the videoflow. Another compact memory interface (INT2) receives a compact memory (MC). Aselector (SEL) directs information from former memory interface towards control moduleor latter memory interface.
