SYSTEM AND METHOD FOR PROVIDING CONTENT FOR DIGITAL RIGHTS MANAGEMENT

摘要

A method of providing DRM content, including transmitting, by a content issuer, when a request for a specific main content of a communication terminal is input, a DRM content including the main content and a preset sub-content corresponding to the main content to the communication terminal; transmitting, by a rights issuer, a rights object having constraint condition information for securing reproduction of the sub-content to the communication terminal; and reproducing, by the communication terminal, when the DRM content and the rights object are received, the sub-content by analyzing the rights object and reproducing, when reproduction of the sub-content is complete, the main content. Reproduction of a sub-content in a communication terminal can be secured through constraint condition information of a rights object, and waste of resources required for providing a sub-content can be suppressed.
