A Cost Model and Copyright Management for 3D Digital Contents Using Multilevel Complex Objects

摘要

The authors discuss multimedia data communica- tions using the Internet from the standpoint of providing services, and propose a cost model based on multilevel complex objects for the purpose of responding to the vari- ous needs of users. The proposed cost model creates multi- ple level of the service which provide each element of the complex object, and then introduces the concept of "service ranges" that can dynamically vary the service which can be received within the scope of the price paid. Conventional multimedia data can only provide one service.
