本論文旨在探討兩種主要的網路資料傳輸技術：主從式傳輸技術與點對點式交換技術對於音樂產業智慧財產權的影響。選定音樂產業作為研究對象，係因音樂產業自從mp3音樂壓縮格式風行以來，其高品質與高壓縮比例的特性，使音樂出版品不斷遭到非法重製，著作權人的權益也因此不斷遭到侵害。檢視此一事件的來龍去脈，並嘗試從中學習教訓，以求一可行的經營模式，是本論文要進一步探討的。 　　本研究主要研究問題如下： 　　一、美國法律增修條文、新增法案、與最新判例對於音樂出版產業智慧財產權的保護方向為何？ 　　二、依據網路傳輸技術與電腦軟體之特性，政府部門應如何對智慧財產權加以保護與管理，以鼓勵學術與藝術創新，並兼顧相關產業與技術發展？ 　　三、新創事業應如何規劃與執行其商業模式中的智慧財產權策略，以避免可能的訴訟風險？ 　　四、傳統音樂出版產業面臨新科技與新商業模式的挑戰，應如何達成互利雙贏的局面？ 　　本研究主要分析對象為美國與國內線上音樂服務廠商：MP3.com、Napster、飛行網、與ezPeer等四家公司，就其對於傳統音樂產業體系的衝擊與影響加以探討，並提出具體策略建議。選擇這些公司的主要原因有以下幾點： 　　一、營模式包含企業對個人(B to C)與個人對個人(C to C)兩種。 　　二、研究對象都是藉由應用網際網路之科技創新而興起。 　　三、音樂下載服務仰賴上游供應商程度極深。 　　四、音樂下載服務對供應商的經營管理造成重大影響。 　　五、研究對象均可能或已經面臨智慧財產侵權訴訟。 　　本研究之研究方法以文獻與個案分析為主。資料來源有三：第一為網站直接觀察，第二為電子郵件來往與直接訪談方式，第三則為次級資料蒐集。依研究過程與研究發現。本研究結論如下： 　　一、政府部門應加緊著作權法修正案立法腳步，以補足目前對輔助侵害與代理侵害規範不足之處。 　　二、智慧財產權法律知識與法律行動準備方面，國外個案公司較國內個案公司相對充分。 　　三、音樂產業可行的經營模式之一，是整合豐富內容、互動交流、與加值服務的數位音樂平台，而最有能力整合的，是既有資源豐富的傳統音樂出版（唱片）業者。 　　本研究以個案探討方式進行，研究方法屬於內容分析。但因為議題新穎、科技演變迅速，探討身賭與廣度難免有所偏頗或不足之處。展望未來，數位內容產業（按經濟部的定義，數位內容產業包含軟體、電子遊戲、媒體、出版、音樂、動畫、網路服務等領域）已成為政府「兩兆雙星」重點發展產業之一，後續研究可廣泛地就數位內容產業智慧財產權保護與管理進一步研究。 / This research is to discover the impacts of the two major internet data communication protocols, which are client-server and peer-to peer technology, on the intellectual property rights (IPR) of the music publication (recording) industry. The purpose of choosing this theme was that the popular audio file compressing technology, ISO-MPEG audio layer-3, mp3, has changed our daily life dramatically. The features of high audio quality and high compressing capability, accompanying with client-server and peer-to-peer technology, are accelerating illegally duplicating of those songs and all the other audio publications, and such abusing of technology has been infringe on copyrighters’ privilege since the debut day of the technology. To review all the related events, to attempt to gather some lessons learned, and to develop a possible business model, are the efforts to which we want to contribute. 　　There are four major issues of this thesis: 　　1.What has been exposed beyond the latest related IPR laws, acts, and cases in the States about the protection on copyrights of the music publication industry? 　　2.Regarding to the characters of internet and information technology, how congress, government, court, and law enforcement agency could do to encourage innovations of technology, industry and economy growth, and protect IPR? 　　3.How should start-ups plan and execute their business model and IPR associated strategy to avoid the risk of possible IPR related lawsuit? 　　4.Facing the challenge of new technology and business model, what can recording industry do to construct a win-win situation? 　　Four online music service providers in the U.S. and Taiwan have been chosen, which are MP3.com, Napster, Fashionow, and ezPeer. We seek to depict the impacts on current recording industry, and attempts to develop a solid strategy. The reasons of choosing these companies are: 　　1.Their business models consist of two typical categories, which are Business to Customer and Customer to Customer, 　　2.All these start-ups applied internet and information technology, and 　　3.They are no doubt a threat to recording and are or are facing going to face IPR lawsuits 　　The methodology of this research is content analysis, and the materials were gathered form: website evaluating, interview with the users, and secondary data collecting. The conclusions are: 　　1.(Taiwanese) Government should accelerate the progress of modifying copyright law to regulate contributory and vicarious infringement. 　　2.The U.S. subjects are better prepared for IPR laws and affairs than Taiwanese ones. 　　One feasible business model for recording industry is a “Digital Music Platform,” combining with a variety of content, interactive communication, and value-added services. Companies in current recording industry, with profuse resources, are certainly the best candidates.
