中文摘要 | 為提昇國內視訊服務品質,厚植國家資訊基礎建設,本計劃配合NII隨選視訊先導實驗計劃,於新竹科學園區進行隨意選取視訊服務試用,負責「混合式光纖同軸網路」建設。本文即以此試驗網路的建設歷程為綱要,文中並陳述整體網路的設計施工、性能測試與此網路的維運發展。由於本網路係作為雙向「隨意選取視訊服務」使用,因此於網路建設後量測其整體性能,以期符合隨意選取視訊服務試驗網路規格之需求。建設此網路之主要效益有三,一是提供國內第一個現場網路以進行隨意選取視訊服務試驗,二是提昇國內研製混合式光纖同軸網路與隨意選取視訊系統相關設備之能力與技術,三是建立混合式光纖同軸網路規劃設計、施工測試與維護管理之技術,作為日後制定規格之參考依據。 |
英文摘要 | According to the video Information Infrastructure Testbed (VIIT) project of National Information Infrastructure (NII) Promotion Group, we deploy a high quality two-way Hybrid Fiber/Coax (HFC) network in Hsin-Chu Science-Based Industrial Park for video-on-demand (VOD) service trial. This paper outlines the deployment processes, and describes the design, installation, and proof testing of this network. The two-way transmission performance of the HFC network is measured and confirmed to meet the specification requirements for two-way VOD trial. Based on the deployment of the HFC network, we provide the first field trial testbed for VOD applications, and develop the techniques of HFC network design, installation, and maintenance. The experience can be a good reference for the specification and deployment procedure for HFC network. Besieds, we expect the manufacturing capabilities and service technologies of HFC and VOD-related equipment can be enhanced through the trial. |
