Now the network has become an indispensable part of our daily lives.
People are more dependent on the network, the higher the expectations of the network, the more to promote the emergence of new Internet applications. Represented by a real-time Internet communications new business more than ever a strong impact on the traditional telecom services and traditional business model. It not only can communicate through the Internet and people, but also to achieve and computer communications, this is the media player. Man and machine communication in this mode, the content appeared in the concept of distributed networks, distributed multimedia server in the network edge to provide a rich and timely for people to all kinds of multimedia programs, users only need to follow the menu prompts or retrieval on demand, can get the content needed to play.
Interactive broadband media player business is generated by the telecommunications network environment, new business, it is totally different from any previous telecommunications business. Interactive multimedia player business with the following operational characteristics:
It is not communication between people, but the communication between man and machine, which determines that it is to have the characteristics of human-computer interaction;

It must have enormous information storage capacity.
Operational characteristics from four shows, interactive media player business is a new, complex business. It not only reflected in the complexity of technology, in the business model and industry chain is very complex.
Interactive multimedia broadcast services business, more general, the techniques involved more and more complex. How to attract a number of content providers to participate in business to provide rich content, we need to address the issue of digital copyright protection, need to study the digital content protection solutions for digital content of the wholesale, procurement, settlement and a series of targeted upstream customer business model. On the other hand still need to be massive content management and retrieval problems, and the nomadic nature of terminal management and billing strategies to end-users and so on technical and operational aspects.

The most prominent of these problems is the lack of content, interactive multimedia broadcast services is precisely reflected the characteristics of different types of mass can be integrated program content, to provide users with retrieval and playback services. From this point of view, the business operator must rely on the contents of the content providers to launch security operations. From the perspective of content providers, business operators on how to protect content from piracy, how to protect content providers shall return. With these questions, the content providers currently no one is willing to take the initiative to provide content, which is an interactive multimedia services can not be carried out very quickly one of the reasons.
