Problems solved by technology

[0002] At present, in the live star dual-mode set-top box, it is possible to watch live satellite programs and terrestrial wireless digital TV programs at the same time. The programs on the live star satellite are encrypted with the existing CA, and the existing CA card of the live star dual-mode set-top box is used for authorization. Management and decryption, but terrestrial programs are not encrypted, and there is no way to perform authorization management and conditional access, and there is no function of banning and reporting illegal programs

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] figure 1 It shows the structure of the embodiment of the system of encryption authorization and management of set-top box terrestrial programs of the present invention. See figure 1 , the system of this embodiment includes a set-top box 1 and a management center server 2.

[0012] Main board 10 and locking module 12 are installed in the set-top box 1, and locking module 12 connects main board 10 by RS232 interface (also can be serial port, such as USB etc.), and is connected to Internet (two-way) by wireless network. The management center server 2 sends the downlink control signal to the set-top box 1 (one-way) through the satellite or terrestrial wireless digital TV network, and the motherboard 10 of the set-top box sends the downlink control signal to the locking module 12, and the management center server 2 directly communicates with the loc...

Abstract

The invention discloses a system for encryption authorization and management of ground programs of a set top box. The aim of encryption authorization and management of ground programs is realized by a locking module in the internal of the set top box. The technical scheme is as follows: the system comprises a set top box and a management central server; the set top box is provided with a main board and a locking module; the locking module is connected with the main board and connected with the internet by a wireless network; the management central server sends downlink control signals to the set top box by a satellite or a ground wireless digital television network; the main board of the set top box sends the download control signals to the locking module; and the management central server directly communicates with the locking module in a two-way manner by the wireless network for passing the management information and the service information.

Description

technical field [0001] The invention relates to an encryption authorization and management system, in particular to a system for encryption authorization and management of set-top box terrestrial programs. Background technique [0002] At present, in the live star dual-mode set-top box, it is possible to watch live satellite programs and terrestrial wireless digital TV programs at the same time. The programs on the live star satellite are encrypted with the existing CA, and the existing CA card of the live star dual-mode set-top box is used for authorization. Management and decryption, but terrestrial programs are not encrypted, and there is no way to perform authorization management and conditional access, and there is no function of banning and reporting illegal programs. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, providing a set-top box terrestrial program encryption authorization and management system, using ...
