Problems solved by technology

Among them, only the main operator has the right to modify the security device and private information, and the main operator needs to notify other auxiliary operators through the interaction between operators. This makes the system more complicated on the one hand and convenient on the other. The operation process is cumbersome and brings trouble to the management staff

Embodiment 1

[0038] The invention provides a digital TV receiving terminal. image 3 is a schematic structural diagram of a receiving terminal according to an embodiment of the present invention, such as image 3 As shown, the receiving terminal includes a descrambling unit 303 and a display unit 304 ; in addition, the receiving terminal also includes a receiving unit 301 and a security device 302 . Wherein, the receiving unit 301 is used to receive the program information and program streams of different operators transmitted by the front-end; the security device 302 is used to judge whether the program information is Perform processing; when the judgment result is yes, process the program information.

[0039] In this embodiment, the program information may include entitlement management information and entitlement control information. Wherein, the authorization management information is an EMM data packet, and the authorization control information is an ECM data packet. The program i...

Embodiment 2

[0058] The invention also provides a safety device. The composition and functions of the components of the safety device are as described in Embodiment 1, and will not be repeated here.

[0059] It can be seen from the above that the security device can store information of multiple operators, and decrypt and descramble program information of multiple operators according to the information. The security device has a simple structure and low cost.

Embodiment 3

[0061] The present invention also provides a method for processing program information, which is used for multiple operators operating in a conditional access system at the same time. The method includes: processing program information of different operators through a security device, so that end users can watch Programs from different operators.

[0062] As can be seen from the above, the present invention can process program information of different operators through one terminal security device, allowing users to watch programs of different operators, enriching the program content of terminal users, and allowing end users to watch programs of multiple operators Brings great convenience, and the number of operators is not limited.

[0063] In this embodiment, the program information of different operators can be processed through one security device in the following manner: the security device receives program information of different operators, wherein the program informati...

Abstract

The invention provides a program information processing method, a safety device and a receiving terminal. The method is used for the simultaneous operations of a plurality of operators in the same conditional access system, and comprises the step of: processing the program information of the different operators through one safety device so as to enable terminal users to watch programs of the different operators. When processing the program information of the different operators, the program information processing method is not limited by the number of the operators and is simple to implement,brings great convenience to the use of the terminal users, enriches the program contents of the terminal users, and in addition, saves the operation cost and brings a greater profit space to the operators.

Description

technical field [0001] The present invention relates to digital TV program receiving technology, in particular to a method for processing program information in a conditional access system supporting multiple operators, in particular to a method for processing program information, a security device and a receiving terminal. Background technique [0002] At present, a conditional access system (CAS: Conditional Access System) is used to control users to perform conditional access to broadcast services, and realize paid services of the broadcast system through authorization management. [0003] In this conditional access system, a CAS operator refers to a manufacturer who purchases a conditional access system from a CAS supplier and actually operates it, usually a TV station at all levels. At present, a conditional access system is built and operated by a single operator to provide TV program information. The operator's operation method is mainly one-to-one correspondence betw...
