Embodiment Construction

[0039] While the present invention can be modified in various ways and has numerous embodiments, specific embodiments will be shown in the drawings and described in detail.

[0040] However, it is not intended to limit the present invention to specific embodiments, and it should be understood that embodiments include all changes, equivalents, and substitutions included within the spirit and technical scope of the present invention.

[0041] Terms such as first and second may be used to describe various elements, but the elements should not be limited by the terms. Terms are only used to distinguish one element from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present invention. The term "and / or" includes a combination of a plurality of related and described items or any one of a plurality of related and described items.

[0042] When an element...

Abstract

The present invention relates to a method, device and system for downloading content based on authority verification. A content downloading method is executed by a first device, the method obtains digital rights management (DRM) information about the resource from resource metadata associated with the resource, and obtains DRM capabilities about the second device, based on the obtained DRM information and DRM capabilities, perform permission verification for using the resource through the second device, and send a queuing request to implement the resource through the second device based on the result of the permission verification. Therefore, in order to be able to consume content, authority verification can be performed based on device capabilities and content information, and content can be stably and efficiently downloaded using the target device based on the verification results.

Description

technical field [0001] The present invention relates to a content download method, device and system based on authority verification, and more particularly, to a content download technology in which authority verification based on device capabilities and content information about content consumption can be performed and can be passed through a target device download content. Background technique [0002] In recent years, as data communication standards and terminal standardization are enforced and devices become intelligent, there is an increased need to construct a more efficient and convenient system by associating multiple devices and services with each other. A representative example that meets this need is a home network. A home network connects devices and services distributed across numerous locations through wired or wireless communications. [0003] Typically, such home networks are based on the Digital Living Network Alliance (DLNA). DLNA is a public partnership...
