Sat>IP (or Sat-IP) is a protocol and IP-based architecture for receiving and distributing satellite signals. In a Sat>IP system, satellite-delivered DVB-S and DVB-S2 (also DVB-T/T2/C/C2) signals are demodulated and converted to IP in a Sat>IP server close to the point of reception and distributed over an IP network, like normal IPTV, to any IP-enabled client multimedia device. Tablets, PCs, laptops, Smartphones, “connected” TVs, video game consoles, media players, etc. can all be used as satellite viewing clients. SES unveiled and demonstrated Sat>IP at the fifth annual SES Industry Days conference showing the distribution of satellite programmes over CAT5 Ethernet, Power Line, plastic optical fibre and WiFi networks.〔(''A Home Base For Distribution Of Content'' ). Satnews.com April 30, 2012〕 The first devices implementing the Sat>IP protocol became available in 2012. ==Overview== Sat>IP is particularly aimed at satellite TV distribution in the home but can be applied to large multi-dwelling and hospitality reception systems too. Conventional satellite TV reception systems convert the received transmissions to an intermediate frequency (IF) for distribution via dedicated coaxial cables to one or more satellite tuners and demodulators in set-top boxes. Sat>IP allows the satellite TV distribution to share a data network and enables display and viewing of the signals on any multimedia IP device equipped with suitable software. Multiple Sat>IP servers and clients can operate on the same network with both free-to-air and encrypted pay-TV transmissions. The intention of the Sat>IP Project is to make Sat>IP an international standard that can be widely implemented worldwide and compatible across manufacturers and operators. The Sat>IP protocol was developed jointly by the Sat>IP Project partners, satellite operator SES, UK broadcaster BSkyB, and Danish TV software company Craftwork. Prototype Sat>IP equipment and the first certified Sat>IP converter was developed by Inverto Digital Labs, a Luxembourg-based Set Top Box and software designer. SAT>IP is a license free technology available to all manufacturers.〔(SAT>IP website ) Accessed May 2, 2013〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sat-IP」の詳細全文を読む スポンサード リンク
