Problems solved by technology

[0005] In the process of realizing the present invention, the inventor found that the prior art has the following defects: the operator implements authorization management through EMM, and implements program management through ECM, that is, EMM and ECM are separated. Therefore, if the user refuses to receive EMM after possessing the authorization of the program The data package can be separated from the authorization management of the operator, that is, the illegal user can illegally have the right to watch the original authorized program by not receiving the anti-authorization package, which violates the vital interests of the operator

Embodiment 1

[0030] An embodiment of the present invention provides an authorization management method, which includes: performing user authorization management by receiving authorization control information including authorization management information delivered by a front end.

[0031] In the prior art, the operator implements authorization management through EMM. If the user refuses to receive the EMM data packet after possessing the authorization of the program, it can break away from the authorization management of the operator. Illegally owning the right to watch original authorized programs all the time violates the vital interests of operators.

[0032] Therefore, in the embodiment of the present invention, in order to prevent the user from refusing to receive the EMM package and depart from the operator's authorization management, it is particularly proposed to perform user authorization management through the authorization control information ECM. Because if the terminal device ...

Embodiment 2

[0042] An embodiment of the present invention provides an authorization management method. The method will be described in detail below with reference to the accompanying drawings, taking the front-end configuration including freezing information and anti-authorization information as an example.

[0043] On the frontend:

[0044] Step 101, the front end configures the authorization management information to generate program configuration information.

[0045] In this embodiment, the authorization management information may be configured as freezing information or anti-authorization information. Wherein, the freezing information may include the information identification of the freezing information and the equipment identification of the terminal equipment to be frozen; the anti-authorization information may include the information identification of the anti-authorization information, the equipment identification of the corresponding user terminal equipment and the product identi...

Embodiment 3

[0073] An embodiment of the present invention provides a conditional access system front end, such as figure 2 As shown, the front end includes: an information configuration unit 201, an information reading unit 202, an authorization control information generating unit 203, and an information sending unit 204; wherein,

[0074] The information configuration unit 201 is used to configure the authorization management information to generate program configuration information; the information reading unit 202 is used to read the program configuration information configured by the information configuration unit 201; the authorization control information generation unit (ECM generation unit) 203 , for generating entitlement control information according to the read program configuration information, where the entitlement control information includes entitlement management information; the information sending unit 204 is used for sending the entitlement control information ECM genera...

Abstract

The invention provides an entitlement management method, terminal equipment and a front end. The method comprises user entitlement management through entitlement control message which is transmitted by the receiving front end and comprises entitlement management message. Through the embodiment of the invention, the method can effectively prevent a user from refusing to receive an EMM (entitlement management message) packet to separate from entitlement management of an operator, so that the terminal equipment realizes program management of the operator at the same time of receiving an entitlement control message (ECM) data packet, realizes user entitlement management of the operator at the same time and effectively protects the vital interests of the operator.

Description

technical field [0001] The invention relates to digital television technology, in particular to an authorization management method, terminal equipment and a front end. Background technique [0002] In the digital TV system, the conditional access system (CAS: Conditional Access System) refers to the system used to control the user to receive the broadcasting service. Usually, the paid service of the broadcasting system is realized through authorization management and authorization control, so as to ensure the authorized Users can receive corresponding authorized TV programs and services, while unauthorized users cannot obtain TV programs and services. [0003] The front end of the conditional access system packages several channels into a product. After the package is packaged, if the user orders the product, the conditional access system needs to be authorized. The authorization information is generally sent to the set-top box through the entitlement management message (EMM...
