Digital signage is a Digital Information Display (DID) which expresses traditional advertisements of outdoor billboards by digital. In early digital signage was limited to provide contents consists texts, images and videos, but now it is combined with the network so contents can be installed, operated and replaced from a distance. Furthermore interaction with users and with user's mobile terminals is getting important. Thus, the transfer of contents between digital signage terminal and user's mobile terminals will occur frequently. In this paper, we suggest the structure of the digital signage system and the efficient method of content sharing through the diagram of the system structure and signal flow.
