摘要： A method, a system, a Rights Issuer and a user terminal are provided for restricting the users of media content. For restricting the users of media content, a DRM agent inside a user terminal obtains the copyright control information that carries the user identity of the current media content, receives a rights verification request that carries the identity of the current initiator of the current media content, and checks whether the current initiator can trigger the play of the current media content according to the user identity in the copyright control information mentioned previously and the identity of the current initiator carried in the rights verification request. If the current initiator is allowed to trigger the play of the current media content, the DRM agent provides the current decrypted media content to a media player. Otherwise, the DRM agent forbids the media player to play the current media content. The users of media content can be restricted based on the actual service requirements and thus a media content provider can better control the right to use its media content.
摘要翻译：提供方法，系统，权利发行者和用户终端来限制媒体内容的用户。为了限制媒体内容的用户，用户终端内的DRM代理获取携带当前媒体内容的用户身份的版权控制信息，接收携带当前媒体内容的当前发起者的身份的权限验证请求，并检查当前发起者是否可以根据先前提到的版权控制信息中的用户身份和权限验证请求中承载的当前发起者的身份触发当前媒体内容的播放。如果允许当前发起者触发当前媒体内容的播放，则DRM代理将当前解密的媒体内容提供给媒体播放器。否则，DRM代理不允许媒体播放器播放当前的媒体内容。可以基于实际的服务要求来限制媒体内容的用户，因此媒体内容提供商可以更好地控制使用其媒体内容的权利。
