Embodiment Construction

[0013] Please refer to figure 1 As shown, it is a system architecture diagram for implementing the information distribution system of the present invention, the information distribution system includes:

[0014] The first-level editing and authority control module 100 edits the information sent by the first-level area (such as the entire area), and controls the authority of using and accessing the receiving terminal 300;

[0015] The first-level distribution module 101 is connected with the first-level editing and authority control module, and is used for distributing the information edited by the first-level editing and authority control module to the lower-level distribution module;

[0016] The second-level editing and authority control module 200 edits the newly added information in the second-level area (such as a local area), and controls the use and access authority;

[0017] There are multiple secondary distribution modules 201, receiving the content output by the pri...

Abstract

The invention discloses an information distribution system, which comprises a primary distribution module, a primary edition and right control module, a secondary distribution module, a secondary edition and right control module, a broadcasting signal transmission module and a receiving terminal, wherein the primary and secondary edition and right control modules are connected with the primary and secondary distribution modules by security channels respectively, and are used for editing information distributed by the primary and secondary distribution modules, and controlling own access rights; the secondary distribution module receives the information from the primary distribution module by the security channel, and also adds new information by the secondary edition and right control module; and the secondary distribution module is connected with the broadcasting signal transmission module, so that the information output by the secondary distribution module is distributed to a plurality of receiving terminals in form of broadcasting signal by the broadcasting signal transmission module. Therefore, the information distribution system fully utilizes the advantages of a broadcasting network, improves the convenience and security of information transmission, and reduces the construction cost of the whole system.

Description

technical field [0001] The invention relates to an information distribution system, in particular to a multi-level information distribution system. Background technique [0002] Most of the existing information distribution systems are directly connected to each receiving terminal through the central first-level system, and adopt the network connection technology based on IP packet switching. The advantages are: 1. The connection is flexible, and the terminals distributed in the distance can be connected to the system server ; 2. The implementation cost of terminal information differentiation is low. Since a lot of terminal information in different places is very different, users need to customize the information put on the terminal, and the way based on IP network connection is easier to realize. But its disadvantages are: 1. When the number of terminals is large, the operating cost is relatively high. Since telecommunications are usually billed by data traffic, when the nu...
