數位化技術的發展，改變原本電視廣播服務的傳遞方式，隨之而來的高品質影音與多樣化內容，使得數位電視的廣播服務，已經大不相同於過去的傳統電視廣播服務。在目前數位電視的標準中，尤以歐盟的Digital Video Broadcasting (DVB)發展最為快速且普及。而近年來，因應多媒體(Multimedia)與網際網路(Internet)相關技術之發展，DVB開始著手推動互動式(Interactive)電視與電視網路化的願景。為了實現互動式電視與電視網路化的夢想，DVB制定了家庭多媒體軟體平台(Multimedia Home
Platform，MHP)標準，提供互動式數位電視與電視網路化之共通平台。在DVB的資料廣播(Data Broadcasting)部分，由Digital Storage Media Control and Command (DSM-CC) 擔任重要角色，在DVB環境中負責提供數據下載服務。本論文透過設計與實作DSM-CC系統，了解資料廣播的資料解析過程，並以系統實作的觀點，探討DVB與MHP規範中所欠缺的部分，例如記憶體管理、DSI、DII與DDB之間的關係、Module Composition、內容更新、Service Domain的管理以及MHP的路徑問題等，提出見解與解決方式，期待成為未來DVB與MHP改進的參考。

During the past years, the Digital Television Broadcast (DVB) standard has been developed rapidly and has also become one of the most popular Digital Television standards. The essential idea of DVB is to replace analog services with digital ones, while DVB2.0 contains a roadmap for the development of digital broadcasting technology. The purpose of DVB 2.0 is to build bridges to the world of computing and telecommunications. With the evolvements of multimedia and Internet techniques, DVB starts to develop interactive TV, of which the data comes from the data broadcasting of DVB. In order to handle the data of DVB data broadcasting, Digital Storage Media Control and Command (DSM-CC) specifications are then defined in DVB. In this thesis, we investigate the data decoding process within data broadcasting by designing and implementing the DSM-CC mechanism. Some issues that are ambiguously defined in the specification of DSM-CC, i.e., memory management, the relation of sections, module composition, content update, management of Service Domain and the problem of path, are clarified. In this thesis, the solutions for resolving the aforementioned issues are also proposed as the references of improving DVB specifications.
