The principle of the VoD system is to increase the accesses among the clients, and to choose the nearest node, (It is different from the traditional on-demand framework .In the traditional framework, it must download source from server-side.) so that, it can effectively solve the problems of the server pressure and bandwidth occupied. It can support more people simultaneously .The deploy is simple. It just needs to install the VJVOD in the server. The VJVOD can support the files of WMV、WMA、FLV、RM、RMVB and ASF to be on-demand online. After you login the website in the client of the network, you can see the program with the WEB Plug-in.
