IPTV





Internet Protocol television (IPTV) is a system through which digital television service is delivered using the architecture and networking methods of the Internet Protocol Suite over a packet-switched network infrastructure, e.g., the Internet and broadband Internet access networks, instead of being delivered through traditional radio frequency broadcast, satellite signal, and cable television (CATV) formats.




互動式網路電視(IPTV)是通過數位電視服務藉由使用網絡連線架構方法和網際網路系列通訊協定封包式網路的一個系統,例如,Internet和寬頻網路擷取網路,取而代之傳統的通過無線電頻率廣播傳送,衛星信號,電纜電視(有線電視)形式。







IPTV services may be classified into three main groups: live television, time-shifted programming, and content (or video) on demand. It is distinguished from general Internet-based or web-based multimedia services by its on-going standardizationprocess (e.g., ETSI) and preferential deployment scenarios in subscriber-based telecommunications networks with high-speed access channels into end-user premises via set-top boxes or other customer-premises equipment.




IPTV業務可分為三大類:電視直播,時光平移(預約錄影功能),以及內容(或視頻)的需求。它不同於一般的以網際網路為基礎或使用網頁式的介面來操作的多媒體服務,經由高速有線頻道進行的標準化程序(例如,ETSI)和優惠部署方案的用戶為基礎的電信網路,到終端使用者住宅設置機頂盒或其他客戶端設備。
台灣最主要發展IPTV的業者以中華電信為首,目前約有十萬左右的客戶,提供三十個固定 的電視節目頻道,同時也提供卡拉OK或是其他 ... 以台灣影視產業的蓬勃,電視為大眾生活 的重心,未來台灣IPTV市場的發展絕對是前景可期
