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 television 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 further includes a receiving unit 301 and a security device 302 . Wherein, the receiving unit 301 is used for receiving program information and program streams of different operators transmitted by the front end; the security device 302 is used for judging whether the program information is carried by the operator identifiers carried by the received program information of different operators Perform processing; when the judgment result is yes, perform processing on the program information.

[0039] In this embodiment, the program information may include authorization management information and authorization control information. The authorization ...

Embodiment 2

[0058] The present invention also provides a safety device. The structure of the safety device and the functions of the constituent parts are as described in the first embodiment, which will not be repeated here.

[0059] It can be seen from the above that the security device can store the information of multiple operators, and decrypt and descramble the program information of the 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 by multiple operators operating in a conditional access system at the same time. The method includes: processing the program information of different operators through a security device, so that end users can watch it. Programs from different operators.

[0062] As can be seen from the above, the present invention can process the program information of different operators through a terminal security device, so that users can watch the programs of different operators, enrich the program content of the end users, and allow the end users to watch the programs of multiple operators. It brings great convenience, and the number of operators is not limited.

[0063] In this embodiment, the program information of different operators is processed by a security device in the following manner: the security device receives the program information of different operators, wherein the progra...

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 a digital television program receiving technology, in particular to a method for processing program information in a conditional access system supporting multiple operators, in particular to a program information processing method, a safety 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 to implement 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, which is 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 operation mode of the operator is mainly one-to-on...
