Study on copyright Law System corresponding to development of multimedia.

本研究旨在探讨在多媒体技术发展及其他数码形式利用版权作品的情况下，版权制度在不久的将来的发展。在作品、表演、录音制品方面，我们面临着通过数字传输或数字点播、闪存等方式进行的新型开发，同时也面临着新旧媒体之间的接口问题，例如广播数字化与数字传输之间的问题。在音乐传播、电子出版、数字广播等数字利用范围不断扩大的今天，寻找一种与技术手段紧密结合的新型版权保护制度已成为我们迫切需要解决的问题。在这方面，我们一直能够审议与1996年12月《世界知识产权组织版权条约》和《世界知识产权组织表演和录音制品条约》相对应的国际、国外和国内发展情况。因此，我们可以清楚地认识到建立一个以加密、水印等技术手段为支撑的权限管理系统的可能性。它是与电子商务、电子认证、电子支付等系统相结合的“电子版权管理系统”。在那里，我们似乎可以谈论版权的“电子”行使，作品开发的“电子”授权。

This study aims to consider a near future's figure of copyright system in the changing environment led by technological developments for multimedia and other digital exploitations of copyrighted works.In respect of works, performances, phonograms, we are facing new types of exploitation through digital transmission or with DYD, flash-memory etc. and simultaneously new issues on interface between old and new media, for example, between digitization of broadcasting and digital transmission. Now, while the scope of digital exploitation such as music transmission, electronic publishing, digital broadcasting is expanding, it has been our urgent task to find out a new copyright protection system with a tight interface with technical means. In this respect, we have been in a position to consider international, foreign and national developments corresponding to WIPO Copyright Treaty and WIPO Performances and Phonograms Treaty of December 1996.Consequently we could clearly recognize a possibility to establish a right management system supported by technical means of encryption, watermarking and so on. It is "Electronic Copyright Management System" combined with other systems such as electronic commerce, electronic certification, electronic payment. There it seems possible for us to talk about "electronic" exercise of copyright, "electronic" authorization of work exploitation.
