A remotely operated vehicle (ROV) called Hercules used visual and acoustic sensors and HDTV imaging systems to help in the excavation of delicate objects in deep water with poor visibility.
As part of oceanographer Dr. Robert Ballard’s recent underwater experiment in “telepresence,” a package of video compression and processing products from TANDBERG Television was deployed in the Black Sea and Eastern Mediterranean to transmit video images from the U.S. Navy research vessel Knorr to students and scientists in the United States.
Ballard, who is known for using an underwater robot technology to find the wreck of the Titanic, has launched remote-controlled underwater vehicles to observe marine life and transmit live video images from the Black Sea via satellite and the Internet 2 to educational viewing locations in the United States.
Two SDI video feeds generated aboard the Knorr were sent to two Tandberg TV video encoders (top) and combined into a single IP video stream using one of the company's multiplexers for transmission to students and scientists in the United States.
Prime contractor Electronic Data Systems and MCI IDB Systems Group, an EDS sub-contractor, selected video IP technology from TANDBERG Television for the project. Two SDI video feeds generated aboard the Knorr were sent to two TANDBERG E5710 video encoders, compressed using MPEG-2 technology, and multiplexed into a single stream for transmission using a TANDBERG MX5620 multiplexer.
The output of the multiplexer was then sent to a TT6120 MediaLink and output as IP traffic, which became a two-way IP feed over satellite for transmission to the new Institute for Archaeological Oceanography at the University of Rhode Island.
