NTT Showcases Total Network Solutions Featuring Industry's Fastest Video Server and Wireless Transmission System That Handle Uncompressed HDTV Multiplexed Signals; General Availability of i-Visto Network System Announced.LAS VEGAS Las Vegas (läs vā`gəs), city (1990 pop. 258,295), seat of Clark co., S Nev.; inc. 1911. It is the largest city in Nevada and the center of one of the fastest-growing urban areas in the United States. -- Nippon Telegraph and Telephone Nippon Telegraph and Telephone Corporation (日本電信電話株式会社 Corporation (NTT NTT Nippon Telegraph and Telephone Corporation NTT New Technology Telescope NTT National Technology Transfer, Inc NTT Name That Tune (TV game show) NTT National Tree Trust NTT Number Theoretic Transform ) will highlight its world-leading video codecs and powerful i-Visto eXmedia server at this year's NAB. NTT will feature a powerful network environment for 10-Gbps-class data transfer, which offers a preview of next generation "all IP broadcasting stations." The industry's fastest video transmission system, the i-Visto eXmedia server has a throughput of 15-Gbps of uncompressed HDTV (High Definition TV) A set of digital television (DTV) standards that offer the highest resolution and sharpest picture. Although some HDTV sets are available in standard (rather square) screen sizes, the overwhelming majority of sets are wide screen, which eliminates video streams and will play a central role in the exhibit. NTT is also announcing that the i-Visto network system will be made generally available in Q3, 2006. The company will also demonstrate the first wireless transmission of multiplexed, uncompressed HD images using 120-GHz-band millimeter-wave wireless link that can transmit 10-Gbps data and will exhibit a HD-SDI bi-directional optical wavelength division multiplexed transmission system. NTT's booth is located in South Hall, Lower Level, number SL2391. NTT showcases the i-Visto eXmedia server connecting multiple HD-cameras, video-editing systems, and monitors via an ultra high speed LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. (10 Gigabit ether network). All the steps in a video broadcast will be demonstrated, including capturing, editing, storing, and delivering video materials via IP networks. The i-Visto eXmedia system is a PC-cluster based server coupled with a disk array and uses a low-delay interconnection network. The HDTV storage server's processing capability can simultaneously store and deliver up to ten uncompressed HDTV video streams. This performance is equivalent to about 100 VTR (VideoTape Recorder) A videotape recording and playback machine. VTR may refer to consumer MiniDV and DV recorders or to professional machines such as Betacam, DVCPRO and DVCAM. video streams. No other video server is capable of matching the i-Visto's performance at this time. The i-Visto eXmedia server and i-Visto Gateway play a key role in the successful multiplexing of the uncompressed HDTV videos. The i-Visto Gateway integrates transmission, storage, and delivery of uncompressed HDTV video streams over an IP network. By combining the 120-GHz-band wireless link and the i-Visto Gateway, the wireless link system is capable of transmitting up to 6 channels of HD video material with zero latency (1) Having no delay between the time a request is initiated and the response is given. See latency. (2) (Zero Latency) Coined by the GartnerGroup, it is the immediate exchange of information across geographical, technical and organizational boundaries so that all . Aimed at TV broadcasters, future applications of the wireless multiplexing transmission system include HDTV signals being relayed live from large-scale public sporting or entertainment-related events. The signals from live event venues will be transmitted by NTT's i-Visto system wirelessly to broadcast stations then broadcast as regular HDTV service. About Nippon Telegraph and Telephone Nippon Telegraph and Telephone Corporation was established in 1952 as a state-owned telecommunications public corporation, and in 1985 converted to a private company, becoming the largest telecommunications company See telecom company. in Japan and the second largest in the world. NTT and its subsidiaries provide a wide range of telecommunications services. NTT Laboratories is the world's finest World's Finest may refer to:
