At present, the key technologies have passed. Media signage interface representation and information transmission communication protocol, have international standard XML (can be extended markup language) and Web Service communication standards, so that a variety of display media can be accepted, programming software only needs to meet the display system interface on the line, more simple than DVD equipment.

The production system needs to provide a variety of tools and media information library about media graphics, images, sound, interface templates, etc. Now the technical focus is how to use the existing tools to integrate a development of teaching word signs platform, and has easy to learn and use fool production function, now the effective composition of this platform is: development and production platform = general platform + special tools + domain media library.

At present, the price of equipment is generally affordable by users. Because the transmission media have optical cables, coaxial cables, five types of lines, wireless communication and routers, the price is very cheap and convenient. In particular, the increasingly large user market has prompted the rapid development of "digital signage".

In the information age, the development of media signs is "unlimited". The emergence and development of various digital media technologies, especially the popularity of flat display devices, has prompted the widespread application of digital media distribution systems in recent years.
