Technologies such as real-time communication, remote data gathering sensors, and advanced visualization have been developed to support the Cyber-environment. Access Grid (AG) technology is used for real-time group-to-group communication and interactions across the Grid. The NCHC has been actively developing AG-enhancing applications since 2003. These developments integrate modern video codecs such as MPEG4 and H.264 into the video (vic) element of AG. This has resulted in a richer and high quality video conference. The NCHC's AG team is committed to developing additional functionality that can contribute to future versions of ANL AG.

The NCHC has designed a sensor network embedded system and collaborated with various hardware suppliers to deploy the necessary resources to collect field data for applications such as Ecology and Flood Mitigation. The system is remotely controlled via IPv6 and IPv4. All the video, audio and measurement data obtained from data loggers are collected real-time and archived so that it can be analyzed by experts anytime, anywhere.

The NCHC's Advanced Visualization team has developed distributed rendering packages such as Image-based Visualization Interface (IvI), IvIsee, IvI4MIE, and IvItune. The NCHC also developed a Multi-Method Streaming Access Server for mono and stereo display and a 4x3 tiled display wall (TDW) that utilizes 24 projectors. The NCHC's TDW is powered by a 13-node cluster. Real-time video/audio streaming, TV programs, and high-definition movies can be shown in the TDW environment. This same technology has been used to construct a LCD-based TDW system.


The NCHC has worked diligently to bring the Cyber-environment into the classroom. As an example, the NCHC used the Access Grid to conduct high-performance computing distant learning courses. The network-synchronized classrooms at NCHC's three business units have been equipped with AG capabilities that include recording, broadcasting, and auto recovery. In addition to the Cyber-education project at the NCHC, there are about 30 primary schools, high schools, and colleges (approximate 100 sites) using the distant learning system to conduct classes. The system has also been selected as the official system for the national multidisciplinary-technology teaching platform. This platform includes instruction on nano technology, optical electronics, and bio-medical technology. About 60 universities will join this project by year's end. The NCHC also provides real-time simulation and collaborative visualization for the multidisciplinary-technology teaching platform.
