Embodiment Construction

[0023] figure 1 is a schematic diagram of an embodiment for realizing the method of the present invention. The specific instructions are as follows:

[0024] 100 Each mobile multimedia terminal is uniquely numbered when it leaves the factory, which is fixed in the terminal hardware and cannot be changed. At the same time, the number can be queried by the user through the man-machine interface or provided to the user in the accompanying manual.

[0025] 110 Each CA card has a unique number, which is fixed in the card and cannot be changed. At the same time, the number can be queried by the user through the man-machine interface or provided to the user in the accompanying manual.

[0026] 120 Input and save the valid CA card number and terminal number in the terminal and CA card management system of the multimedia broadcasting system.

[0027] 200 When a user uses a terminal for the first time, he inserts the CA card into the terminal, and the user is prompted through the ma...

Abstract

The invention relates to a method for bonding machine and card in mobile multimedia broadcast system, which comprises that: (1), fixing one unique serial number of each mobile multimedia receiver, and fixing unique card number for each CA card; (2), when user first uses CA card with mobile multimedia receiver, via man-machine interface, it prompts user to send the receiver serial number and the card number to the condition access system to be bonded; (3), the access system will generate condition receiving information, via broadcast network to be sent to the multimedia receiver; (4), multimedia receiver receives the condition receiving information and sends it to CA card, which will decrypt the information.

Description

technical field [0001] The invention relates to the field of communication, in particular to the field of mobile multimedia broadcasting, and relates to a method for realizing machine-card binding in a mobile multimedia broadcasting system. Background technique [0002] With the development of digital TV technology, viewers will face more and more choices of digital TV programs. However, due to the increase in investment costs, the broadcasting industry requires users to charge certain viewing fees. The conditional access system is a system that implements access control for certain broadcasting services. It uses various digital technologies to scramble programs so that only authorized users can watch (listen) the scrambled programs and realize digital TV. Paid service of (audio) broadcasting system. [0003] The existing digital TV conditional access generally adopts a multi-layer key mechanism to encrypt the transmission program. The key factors of the conditional access...
