Abstract

A rights sharing system and method for digital rights management (DRM) is provided. The system and method allow an inaccessible terminal, which cannot directly access a content providing server that provides a license, to receive only a key value for playing back DRM content from a terminal having a license and to play back the DRM content. Therefore, the system and method enable the inaccessible terminal to play back a DRM content, without mounting a DRM agent to acquire a license thereto.

Description

technical field [0001] The present invention relates to Digital Rights Management (DRM).
