AllVid is a CableCARD replacement proposed by the U.S. Federal Communications Commission's (FCC) National Broadband Plan.〔"(National Broadband Plan. )"〕 The AllVid hardware would act as a universal adapter for all types of pay TV content such as video-on-demand and pay-per-view, as well as interactive programming guides, delivered through a wide variety of means, including cable TV, satellite TV, VDSL, IPTV, and Internet TV. ==Design== The FCC has proposed several design aspects to AllVid while soliciting feedback from interested parties on a final specification before going forward for rulemaking. Major elements of the FCC's AllVid proposal include: *Gateway device capable of decoding six video streams and feeding through a home network to various devices.〔''(AllVid Notice of Inquiry )'', p.10, 25 FCC Rcd (4284 )〕 *Adapter device capable of decoding two video streams and feeding directly to a television or consumer electronics device.〔 *Physical connection using 100BaseTX Ethernet.〔 *Internet Protocol as a communications protocol between the AllVid gateway and end devices.〔 *Encryption and authentication using the DTCP-IP standard used by the Digital Living Network Alliance.〔''(AllVid Notice of Inquiry )'', p.11, 25 FCC Rcd (4285 )〕 *Content ordering and billing for VOD and PPV services may be handled via gateway generated screens but additional options are requested.〔 *Service discovery may use Universal Plug and Play, as suggested by TiVo, but other proposals are invited.〔 *Content encoding is proposed to support multiple codecs to allow devices flexibility in choice of video formats without requiring transcoding by the gateway.〔''(AllVid Notice of Inquiry )'', p.12, 25 FCC Rcd (4286 )〕 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「AllVid」の詳細全文を読む スポンサード リンク
