MPEG-4 IPMP系統之實現

Abstract

多媒體，例如書本、音樂、電影、電視節目等等，都可算智慧財產的一種。現今網際網路的蓬勃發展，涉及數位化多媒體財產的電子商務日漸普遍。因此，能保護智慧財產和使得智慧財產可以透過更方便的形式作商務交易的技術 ─ 智慧財產的數位化管理和保護 ( IPMP )，將會成為電子商務系統之中不可或缺的一環。 由1997年開始，MPEG組織開始嘗試為IPMP訂立標準的公用介面和相關協定，目標是把IPMP整合到現有的MPEG標準之中。到目前為止，MPEG-4和MPEG-2標準中的IPMP訂定已經快將完成，而MPEG組織也開始投入更多的資源訂定MPEG-21 IPMP標準。 本篇論文主要是研究在MPEG-4多媒體標準中的IPMP系統的標準，然後更進一步設計並實現一套符合MPEG-4 IPMP標準的應用系統。MPEG-4 IPMP系統是一套以訊息傳遞為基礎的系統。在系統之中，由不同的公司、組織單位所發展的IPMP Tool，可以透過已定義的訊息協定作資訊交換。在此，我們希望透過撰寫一些應用例子，展示出這個標準的強大功能。本篇論文主要可以分為三個部分。第一部分，會介紹MPEG-4 IPMP標準的概念、架構和介面定義。第二部分，我們試著整理和追蹤可以組成IPMP系統的一些工具。在最後一部分，我們會建構幾個簡單的IPMP系統的應用例子。

With the widespread of Internet, electronic commercial activities involving the trade of digital multimedia contents over network is getting popular. Therefore, Intellectual Property Management and Protection (IPMP), which protects IP and enables convenient IP trading of contents, becomes an indispensable element of an e-commerce system. MPEG started a standardization effort on specifying a common interface/protocol for IPMP in 1997. They integrate IPMP systems into the existing MPEG multimedia standards. Up to now, IPMP specifications for MPEG-4 and MPEG-2 are nearly completed. The MPEG committee is currently working on MPEG-21 IPMP. The goal of this thesis is to study the MPEG-4 IPMP standards and then design and implement an MPEG-4 IPMP application system. The MPEG-4 IPMP system is a message-based system. Tools such as encryption algorithms developed by different companies or entities can communicate with each other through the use of common message exchange protocol. We thus like to develop application examples that can demonstrate the functionality and powerfulness of this standard. This thesis can roughly be divided into three parts. The first part describes the concept, architecture and interfaces of MPEG-4 IPMP. In the second part, we collect, trace and integrate the software tools that can be used for constructing IPMP application systems. Finally, several application examples have been designed and implemented.
