The manager''s contents production environment is also simple and various contents can be provided by analyzing the requests of users for effectivity, emerging from the simple streaming service without initial establishment costs and installation costs for infrastructures deriving from web services. Various researches should be conducted simultaneously such as researches on automatic pattern recognition technologies which recognizes the sex, age, location among other data of the user and various methods of image processing for the production of contents to elaborate lively contents to provide diverse experience and enjoyable configurations for the future generation. This can be made possible if the Government and relevant organizations endeavor to apply necessary technical factors and solve the existing problems by supporting policies and systems which allow the cooperation and development of different areas and not only one area such as HW, SW, network, contents, etc. and with this the potential of the Digital Signage which is called the fourth media industry will become boundless.
