Abrégé
(EN)
A method and apparatus are provided for providing a DRM service in a user terminal apparatus providing an adaptive streaming service. Content protection information is received that includes information about multiple DRM systems applied to specific content provided using the adaptive streaming service. A specific DRM system is selected from among the multiple DRM systems. A license corresponding to the specific DRM system is acquired. The license includes an encryption key capable of decrypting the specific content. The specific content is decrypted using the acquired license.
