Description

A system for remote management of electronic wallet status technical field The invention relates to a conditional access system in the field of broadcasting, in particular to a system for managing electronic wallets in the conditional access system in the field of broadcasting. Background technique The conditional access (CA, ConditionalAccess) system is the core technology for developing pay TV and broadcasting services. It is to ensure that legal users (called authorized persons) can receive audio and video programs and data services, while illegal users cannot obtain them. related signal. Conditional access has experienced two generations of development, the first generation is characterized by equipment-based, generally used in analog systems. In order to realize the effective charging of cable TV, the analog signal is scrambled at the front end, so that ordinary TVs cannot be watched, and only users who have installed a descrambler can watch it normally. Such a sys...
