Problems solved by technology

Push VOD solves the problem that in a one-way network environment, it is impossible for users to enjoy online on-demand services at any time without using other on-demand request information to return to the network.
[0005] All the business essence of pre-push and on-demand downloading of content to the terminal device is to download the content for subsequent application. These solutions have certain security risks, and it is easy to cause the content to be on-demand to be copied, illegally used and illegally distributed.

Embodiment Construction

[0061] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0062] The main idea of ​​the technical solution of the present invention is to divide the digital TV service system suitable for using the conditional access system for service authorization into a digital content preprocessing module, a digital content distribution module and a digital content use control module, and the digital content preprocessing module further includes adding scrambler or encryption machine, pre-scramble or pre-encrypt the digital content; the digital content distribution module distributes digital content to the terminal set-top box, and is used to generate authorization information and distribute it to the terminal set-top box; the digital content use control module is located in the terminal set-top box to analyze the authorization information and descramble or decrypt digi...

Abstract

The invention discloses a method and a system for managing digital rights. The method comprises the following steps: a digital content is pre-treated and the pre-treated information is sent to a subscriber certificate server or a key management module; an authorization control message is generated and sent to a pre-treating device according to the pre-treated information; the authorization control message is added to the digital content and sent to a terminal top-set box by the pre-treating device; a user requests the digital content from a business operation support system or a subscribe management system, and the business operation support system or the subscribe management system generates and sends an authorization message to a license server; the terminal top-set box acquires the authorization message from the license server, analyzes the digital content added with the authorization message and uses the digital content. The technical scheme of the invention can be compatible with the prior one-way or two-way digital television services without influencing the conditional access system widely used at present, and guarantee the use security of downloading or sending the content.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a digital rights management method and system.
