  • Patent number: 9544544
    Abstract: A method and system for sharing information between users while reproducing media in a media reproducing system, the method including: reproducing the media in the media reproducing system; capturing a part of the media in the media reproducing system; and registering a media related question including the captured part of the media in an information sharing server through a return channel of the media reproducing system. Accordingly, the users can share information in real time by generating the media related question by directly capturing the media in the media reproducing system, registering the media related question in the information sharing server, and displaying on the media reproducing system of another user that such media related question is registered. Also, since a question can be directly registered while reproducing the media, information can be conveniently shared without interrupting the media reproduction.
