Novel High-Resolution Detector for X-Ray CT and DR

Three challenges must be addressed in order to develop efficient hardware compression of video data for Distributed Interactive Simulation: (1) 10 microsecond latency requires supercomputer power; (2) the compression algorithm must be developed carefullyin order to preserve low latency and high image quality at the same time; (3) asynchronous transfer mode (ATM) interfaces must be optimized to seamlessly transmit high-quality-of-service streaming video with minimal latency. Physical Optics Corporationproposes the Video/Imagery Super-Parallel and Supercomputer-Path (VISPII) system and interactive streaming video ATM network, which responds to all these challenges. In Phase I, a demonstration-ready prototype VISPII system with unique hardware has beendeveloped that combines 10:1 compression, peak signal-to-noise ratio = 40 dB, and 15 ms latency. In Phase II, the latency will be reduced to 10 microseconds, and a full prototype VISPII ATM network will be developed, including new integrated circuithardware and interface frame synchronization for seamless transmission of streaming video. A broad variety of compressed video standards and over 10 dynamically-allocable video communication channels will be supported by a single OC-3 channel.
