National LambdaRail (NLR) offers unprecedented communication capabilities on the National and possibly International levels. Physical Optics Corporation (POC) proposes to develop a new 3D multichannel networked (3DMCN) system for visualizing large collections of Earth science data in a highly distributed and networked environment, compatible with the high speed National LambdaRail (NLR), with the necessary interfaces and video processing hardware/software. One of the critical issues in the development of such systems is the capability to transmit high-resolution (High Definition format) multi-channel images/video from a central rendering/processing location to multiple visualization stations, which can be thousands of miles apart. To address 3D video/telepresence on the NLR POC will develop special compression software for multi-channel transmission, removing both intra- and inter-channel redundancy. At the end of Phase I POC will demonstrate 3D video transmission over multi-Gigabit Ethernet channels in a laboratory environment. In Phase II a full system with multiple visualization stations connected to the NLR will be developed, including network interfaces, video compression, and 3D video stations.
