增進隨選視訊功能應用之研究

Abstract

本篇論文的環境，由於Vod的研發已歷經多年，在第一章對於當下研究的挑戰與困難在哪裡進行一些探討。 而為了進一步發展VoD的應用，將在第三章對研究的平台加以解釋，亦即對DSS(Darwin Streaming Server)較為深層的介紹。 而身處在數位的時代，數位內容興起，數位服務也崛起，需要一個統合的系統作為中介，負責在不同的伺服器間，或伺服器與使用者之間的互相適應與協調，而伺服器必須建立起與中介伺服器之溝通能力。而為擴展VoD的應用功能，使提供VCR 的功能以及增加VoD的價值。

Since it has been years of VoD researching, the challenge of VoD in current environment is going to be discussed in Chapter 1. For extending applications of VoD based on DSS(Darwin Streaming Server) platform, some effort is spent for understanding underlying schema of DSS in Chapter 3. During the digital age, Digital content , digital services are risen already, but a integrated system as a middle interface is still lack of for adapting and negotiating among servers and clients. Therefore the VoD server must be able to communicate with middleware to extend service provision, to increase value of VoD service. And also, fashion VCR request handling capability is discussed in this thesis.
