摘要

傳統的內容資訊傳播方式，用戶端只能被動接收內容資訊，也無法與內容提供者即時互動。近年來隨著寬頻網路普及以及頻寬一再的提升，利用網路當作內容傳輸的媒介不再是夢想。透過網路串流的機制，使用者可以即時選擇網路提供的數位內容。使用者都希望隨時能夠選擇喜歡的影音資料，即時傳送下來並觀看。而在服務日益增多，如何讓使用者以便利的方式來使用多項服務，是個難題。在這裡引入中介伺服器（Middleware Server）的角色，扮演溝通橋樑的角色，整合後端眾多伺服器，提供完整的應用介面給予使用者。而在影音串流伺服器本身，更應該有進階性功能讓使用者能享受到人性化的操作，所以影音串流伺服器便利搜尋播放功能的存在有其必要性。在這裡我們探討和比較了許多的實際作法，亦提供了一套方法，希望能加速VOD(Video on Demand)市場的發展，亦引出使未來功能再強健的可能性。

Traditional content information circulation way, the end-user can only receive the content information passively , it is inter-dynamic immediately with the content provider to be unable. Popularize with the wide-band network and the network bandwidth improvement constantly in recent years, it is no longer the dream to utilize the network to regard the media transmission. Through one bunch of mechanisms of streaming of network, the user can choose the digital content that the network offers immediately . The users all hope to choose the audio-visual materials liked at any time, convey and watch immediately. And services are increasing day by day, how let user so that way of profit is it use multiple service to come, pieces of difficult problem. Introduce the role of the intermediary server (a server of the middle ) here, play a which link up the bridge role, combine the numerous servers of back end, offer the intact application interface to offer users. Audio-visual bunch shed server itself, should enter steps nature functions and enable users to enjoy humanized operation even more, so audio-visual bunch flow server convenient to is it broadcast existence of function have their necessities to search. We have probed into and compared a lot of actual practices here, have also offered a set of methods , hope to accelerate the development of the market of VOD (Video on Demand ), the possibility with more strong function in the future that also draw making .
