Problems solved by technology

In the three-screen-in-one scenario, there may be situations where a certain terminal of the user does not have a networked application environment, and the user wants to use the offline terminal to play downloadable DRM content
[0004] However, OMA DRM is only applicable to mobile media environments such as mobile phones and TVs, and the scope of application is relatively small, and OMA DRM's support for offline devices limits that offline devices and networked devices must support OMA DRM and must belong to the same domain
In the future three-screen scenario, there will be user terminals supporting different DRM types, and OMA DRM’s support for offline devices cannot meet this requirement
[0005] However, Marlin DRM currently restricts users' terminal devices to networked devices, and does not support offline devices to play DRM content.
[0006] In addition, OMarlin currently only considers how to achieve the compatibility of the two DRMs when the networked devices support OMA DRM and Marlin DRM respectively. It does not implement the management support for the use of DRM content on the user's offline device, and cannot meet the requirements of the user's offline device for DRM content. playback requirements
[0007] In summary, when the networked device and the offline device support different DRM types or belong to different domains, the existing technology cannot meet the playback requirements of the offline device for DRM content; in addition, in the Marlin DRM system and the OMarlin DRM system, Existing technologies cannot meet the playback requirements of offline devices for DRM content

Abstract

The invention provides a digital rights management content playing method, a user equipment and a domain manager, wherein the DRM (digital rights management) content playing method comprises the following steps that: a networking device sends a browser session request to a domain manager, and receives a browser session response carrying a second URL (Uniform Resource Locator), a trigger file and session identifiers sent by the domain manager; the networking device saves the second URL (Uniform Resource Locator) and the session identifiers, sends the trigger file to an off-line equipment to trigger the off-line equipment so as to execute the incoming flow, and receives and plays the DRM (digital rights management) content sent by the networking device after incoming. The method can be used for realizing that the off-line equipment obtains the DRM (digital rights management) content and the authority of playing the DRM (digital rights management) content through the networking device, so that the off-line equipment can play the DRM (digital rights management) content.

Description

technical field [0001] The invention relates to digital copyright technology, in particular to a method for playing digital copyright management content, user equipment and a domain manager, and belongs to the field of communication technology. Background technique [0002] Digital Rights Management (Digital Rights Management; hereinafter referred to as: DRM) technology realizes the protection of digital content, such as e-books, videos, audio and pictures, etc., through certain security algorithms / protocols and security management methods, so that digital content can Operations such as use, copying and distribution cannot be carried out under the conditions of authorization and permission. At present, Internet Protocol Television (IPTV for short) mainly adopts DRM technology to realize the protection of media content, and manage the playback and use of content by user equipment. In the three-screen-in-one scenario, there may be a situation where a certain terminal of the u...
