NTT-AT and NTT Showcase Ultra-Low Latency HD video transmission system and Ultra-High-Speed Video Server System for High-Resolution Video

NAB Show 2009, LAS VEGAS, April 20, 2009 - NTT Advanced Technology Corporation (NTT-AT) and Nippon Telegraph and Telephone Corporation (NTT) will highlight the ultra-low latency HD video transmission system “HDTV-IP gateway (XG-2)” and the ultra-high-speed video server system “HDTV-IP video server (XMS)”at NAB Show 2009. These products, which are able to transfer high-quality video through an IP network instead of transporting tapes, will accelerate the change to “all IP broadcasting stations.”

The HDTV-IP video server “XMS” is a PC-cluster-based ultra-high-speed video server. It can record and play back a number of high-quality video files, such as compressed HD, uncompressed HD, and uncompressed 4K-resolution, through an IP network in real-time. It can record and play back video using legacy video equipment, such as an HD video camera and an HD monitor, and can also transfer video as video files to/from PC based non-liner editing systems. The server can simultaneously record and play back up to 16 uncompressed HD videos. This performance is equivalent to about 200 HD-VCR quality videos or four uncompressed 4K-resolution videos.

The HDTV-IP gateway “XG-2” is an ultra-low-latency video-transmission system through an IP network. It can convert an HD-SDI/SD-SDI signal from/to IP packets within one millisecond and transfer them through two gigabit-ethernet interfaces without compression. The system is portable and consumes less power making it ideal for use at offsite locations.

NTT-AT and NTT will showcase the “XMS” connecting to an HD-camera, non-linear editing systems, transcoding systems, and playout systems via an IP network and demonstrate all the steps in a broadcasting station including recording, editing, and playout. The companies will also demonstrate an unmanned live camera system using “XG-2” and demonstrate that a live camera can be smoothly controlled through an IP network.
