PURPOSE: A 3D virtual mall is provided to search contents only requested by a user so as for a server provider to operate the virtual 3D mall even a high-speed line is not installed and to reduce a communication cost. CONSTITUTION: A user 3D mall(71) is installed in a user computer or communication equipment(60). In case that a user/purchaser makes a request, an MPEG, a CAD, a 2D, a 3D and moving picture contents in a 3D mall(10) of a server(30) are transmitted to a user/purchaser(70). An application program system(40) supports a 3D mall(10), a content search system(21), a content index system(22), a server(30) and so on. The user/purchaser(70) passes through an authentication process from the application system(40) of the server(30). After that, the user/purchaser(70) inputs an index word for contents which the user(70) requests.
