Rural digital film operation system and method

Abstract

The invention discloses a rural digital film operation system and method. The system comprises a cloud platform, an edge server and a playing terminal. The cloud platform generates corresponding token files for different movie sources, encrypts the movie sources to generate encrypted film sources, generates authentication keys for the encrypted film sources, and finally pushes the token files, the encrypted film sources and the authentication keys to the edge server or the playing terminal. And the edge server is connected with at least one playing terminal and authorizes the playing terminal according to the content of the authentication key. And the playing terminal authenticates the encrypted film source through the edge server, and plays the encrypted film source after the authentication is passed. According to the invention, online or local authentication is supported, the film transmission period is shortened, the timeliness of film broadcasting is improved, the manageability of the playing terminal and the film is increased, and meanwhile, the possibility is provided for real-time online playing of the playing terminal under the condition that the network bandwidth is allowed.

Description

Technical field[0001]The present invention relates to a digital information transmission system and method, and more particularly to the operation system and method of rural digital movies.Background technique[0002]Under the current rural network, the rural public welfare film screening mode uses semi-artificial ways, and the film is mainly through satellite link or hard disk express, and the encrypted film is delivered to the film service station of various districts and counties. The authorization of the video playback is a playback field control and the demobilization of the entity IC card.[0003]In this mode, whether orientated by semi-hand copying, the film is delayed, the entire link has a relatively low work efficiency, and there is a single-point device fault problem such as reading a hard disk failure, read IC Authorization fault, physical damage to the equipment, etc.[0004]With the development of network technology and the upgrade of rural networks, the original movie trans...

AI Technical Summary

Problems solved by technology

[0003] In this mode, whether it is through semi-manual copying and transmission of movies or physical IC card authentication and playback, the work efficiency of the entire link is relatively low, and there are problems with single-point device failures on the link, such as reading hard disk failures, reading IC cards, etc. Authorization failure, physical damage failure of equipment, etc.
