TANDBERG Television equipment helps unlock the mysteries of the sea


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.

TANDBERG Television recently supplied oceanographer Robert Ballard with video compression and processing equipment that was used to transmit video from a U.S. Navy research vessel in the Black Sea and Eastern Mediterranean to students, scientists and the public.

Ballard, who is renowned for using underwater robotic equipment to find the Titanic, used remotely operated underwater vehicles, video equipment, and satellite and Internet2 links to transmit video as part of the Immersion Project, a production of the Mystic Aquarium & Institute.

Two SDI show feeds generated aboard the Knorr research vessel 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 sent to a TANDBERG 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.
