Claim:
1. An electronic device comprising: a mobile high-definition link (MHL) module; and at least one processor operatively coupled to the MHL module, the at least one processor configured to execute a normal operating system configured to control a content service and a secure operating system configured to receive information for controlling a digital rights management (DRM) service using DRM content from the MHL module, wherein the electronic device includes a first control interface for the normal operating system to provide the content service and a second control interface for the secure operating system to provide the DRM service, wherein the secure operating system controls the DRM service using the received information through the second control interface to limit access of the normal operating system, wherein the MHL module is configured to provide updated information for controlling the DRM service to the secure operating system, wherein information for controlling the DRM service includes high-bandwidth digital content protocol (HDCP) state information, wherein the MHL module is separate from the at least one processor, wherein the second control interface is configured to identify the HDCP state information from the MHL module separate and control the DRM service based on the identified HDCP state information, wherein the second control interface is configured to permit only access of the secure operating system, and wherein the second control interface is further configured to provide a request for the HDCP state information from the secure operating system to the MHL module and provide the HDCP state information from the MHL module to the secure operating system.
