NEC Delivers High Quality Digital Video Fiber Transmission Units to Korean Communications Carriers

Helping to realize Korea’s first nation-wide HDTV networks using non-compression transmission technology

Tokyo, June 17, 2008 - NEC Corporation today announced that it has delivered approximately 180 “NOIF-2000” non-compression video signal optical interface units for transmitting high quality digital images to KT and LG Dacom, which are communication carriers in Korea.

Since delivery of units, KT and LG Dacom have incorporated them into program transmission systems built for KBS (Korean Broadcasting System) and MBC (Munhwa Broadcasting Corporation). Both systems commenced full-scale operation in December 2007 and were put to immediate use for transmitting video programming during Korea’s presidential election held on December 19.

The NOIF-2000 interface converts digital terrestrial broadcasts and other digital video signals into optical signals, enabling long distance transmission. As signals are transmitted without compression, the device delivers high quality program transmission with no video deterioration. Furthermore, the NOIF-2000 can be connected to the “SONET/SDH”* networks, which are backbone networks commonly used by communication carriers. By adopting the NOIF-2000 interface communication carriers can realize a digital video transmission network while still making full use of existing backbone networks.

KT and LG Dacom integrated NOIF-2000 interfaces with their own SONET/SDH networks to realize Korea’s first nation-wide high definition television (HDTV) systems using non-compression transmission for KBS and MBC.

With Korea scheduled to switch from analog to full digital TV broadcasting by 2012, all Korean broadcasters are expected to upgrade their facilities. NEC intends to increase sales of the NOIF-2000 in the global market, starting with Korea and the Asian region for the expansion of business activities in the broadcasting field.

NEC will continue to draw on its extensive experience in the construction of digital broadcasting systems for a wide range of domestic and international broadcasters, as well as its proven track record in the delivery of high quality video transmission units to leading communication carriers, to provide advanced video solutions that leverage Next Generation Network (NGN) technology.

NEC向韩国通讯运营商提供优质的数字视频传输设备

～为韩国首次由非压缩传输实现全国电视转播网作出了贡献～

最近，NEC公司向韩国通讯运营商KT和LG Dacom提供了180台传输非圧缩高清数字电视信号的光传输设备——NOIF-2000。

KT及LG Dacom灵活地运用此设备，为在韩国拥有全国性广播电视网络的韩国广播公社（KBS）和文化广播(MBC)构筑了节目传输系统。2007年12月起，这两个电视台的节目传输系统正式开始使用。同年12月19日，韩国总统选举时也运用了此系统进行了节目传输。为韩国首次由非压缩传输实现全国电视转播网作出了贡献。

NOIF-2000是能对地面数字电视信号进行光转换后实现远距离传输的设备。由于能以非压缩进行电视信号的传输，所以能传输没有图像信号失真的高质量电视节目。此设备不仅能通过一般的光纤线路来传输，而且还能通过被广泛普及的通讯运营商的基干线路网络SONET/SDH网作为传输电视节目的手段来进行利用。因此，通讯运营商引进NOIF-2000能有效地利用已有的基干线路网络实现数字电视光传输网。

KT及LG Dacom把NOIF-2000和两个公司拥有的SONET/SDH网络组合起来,为KBS和MBC构筑了韩国首次的由非压缩传输高清的全国电视网。这两个电视台的节目传输系统是由两路光纤网络构成，并且能同时传输地面数字电视1频道高清和3频道标清的电视节目。

韩国计划将在2012年开始对模拟电视广播向数字电视广播的全面转换。考虑到各广播电视台有数字高清化的设备扩充和广播电视台之间的电视节目传输的需要计划，NEC开始对包括韩国在内的亚洲地区乃至世界各国广泛地扩大销售传输非圧缩高清数字电视信号的光传输设备——NOIF-2000。并且今后将更进一步地推进和扩大此项业务。

此外，NEC有效地利用提供给国内外电视台大量的数字电视广播系统的构筑实际成果和提供给通讯运营商的高清电视节目传输设备的业绩，为今后更进一步地推进提供下一代网络(NGN)的视频解决方案做了铺垫。
