Problems solved by technology

This has increased the network usage between DRM rights object issuer 10 and home server 30 and content issuer 20 and home server 30, wasted the storage space of home server 30
[0015] In addition, in case the home server 30 downloads the HD profile and decodes the downloaded HD profile into a different profile, decryption / re-encryption of the encrypted content and digital signature of the DRM license by the rights object issuer 10 are required , which also poses a security problem

Abstract

A method, apparatus and system for managing A / V (Audio / Video) profiles are provided, which is related to a technology that supports different profiles in a domain. The method of managing A / V profiles includes requesting a license component (S610) and an encrypted content component, and creating (S640) a DRM license and encrypted content by gathering elements that correspond to an A / V profile of aspecified device from the license component and the encrypted content component.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2007-0057602 filed with the Korean Intellectual Property Office on Jun. 13, 2007, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] Methods, devices, and systems consistent with the present invention relate to managing A / V (audio / video) profiles, and more particularly, to a technique for supporting different profiles in a domain. Background technique [0003] Recently, digital rights management (hereinafter referred to as "DRM") has been actively studied, commercial services using DRM have been realized, and more will be realized. The basic idea of ​​DRM is to protect digital content that can be easily copied and distributed. [0004] Several efforts have been made to protect digital content. Traditionally, digital content protection has focused on preventing unauthorized access to digital content by, for example, allowing access to the digital c...
