摘要: Oak Ridge National Laboratory (ORNL) staff have developed a real-time video transmission system for low-bandwidth remote operations. The supports both continuous of driving and progressive still images. Inherent in the design is spatiotemporal limitation to effects channel errors. average data rate 64,000 bits/s, compression approximately 1000:1 black-and-white Television Standard Code video. image quality transmissions maintained at level that teleoperated High-Mobility Multipurpose Wheeled Vehicle speeds up 15 mph on moguled dirt tract. also provides mission package board vehicle. dynamic adjustments allow driver adjust changing scenery viewing requirements. During driving, system`s nominal configuration had frame 4 Hz, per 125:1, resulting latency {approx} 1s.
