臺灣博碩士論文加值系統

本論文研製為解決可以適合各種不同服務機制的開發執行環境，本文特針對此一問題提出一個IPTV服務執行環境－ISEE ( IPTV Service Execution Environment )，此環境支援IPTV服務開發時期與執行時期的各項需求，透過「平台服務組件」設計理念，完整呈現IPTV的互動性，並提供彈性運用及快速新增服務的特點，讓系統業者能依據市場趨勢，快速提供滿足用戶需求的互動電視服務，進而建立用戶品牌忠誠度，提升產業競爭力；另方面，藉由「平台模組化」設計理念，讓Set-Top-Box或Video Server的擴充或更新變得更有彈性及穩定，使系統業者的平台維護更具多元化的選擇空間。
ISEE服務包含在伺服器端執行的程式及在用戶端執行的程式，並以HTTP為兩端之通訊協定。伺服器端程式以JVM (Java Virtual Machine)及Servlet/JSP container為執行環境，並以Apache Struts 為Web應用程式框架，用戶端程式則以支援Javascript/CSS的Web瀏覽器為執行環境。
本文另外提出一基於上述目標之開發工具－ISEE SDK。ISEE SDK是ISEE裡的IPTV服務開發工具，為一符合開放原始碼標準的自由軟體，它採用 [Apache License, Version 2] (http://www.apache.org/licenses/LICENSE-2.0) 的授權條款，服務開發者可自由更改ISEE SDK原始碼，並可自由使用SDK及SDK所開發出的應用服務。使用此SDK可以很容易且快速的開發出支援多種STB的IPTV服務。

A procedure is proposing a service execution environment, ISEE (IPTV Service Execution Environment), that is an open source framework. This environment supports various needs during developing and executing IPTV services, fully presents the interaction of IPTV with the “Service Component Platform” design concept, and has the features that can flexible use and provide new additional service quickly. in order to let service providers to quickly deliver interactive TV services that meet subscriber demands according to the market trends and thereby to build the brand loyalty and to enhance industry competitiveness. On the other hand, the design concept of “modularization platform” is applied to increase the flexibility and stability to expansion or update set-top-box (STB) or video server, and thereby to bring service providers more comprehensive options for platform maintenance.

This paper also proposes the development tool—ISSE SDK based on the above targets. The ISEE SDK is the development tool for the IPTV services in ISEE. It is a freeware comply with the open source standards using licensing terms in Apache License, V2. Service developers can freely modify the ISEE SDK source codes and freely use the SDK and the application services developing with it. The SDK is easy to use and allows users to quickly develop IPTV services to support various STBs
