Tandberg Television Powers HD Under the Sea

A research expedition from the University of Washington to transmit the world's first high-definition footage from the sea floor is using encoding technology from Tandberg Television.

The University's VISIONS '05 underwater expedition is designed to study geologic activity in the underwater volcanoes in the Juan de Fuca Ridge in the northeast Pacific Ocean.

Using the Tandberg Television HD E5780 HD MPEG-2 encoder and TT1280 HD decoder, the HD video was compressed and transmitted live from the research vessel over IP satellite to the University of Washington, where it was streamed over the Internet to research facilities across the United States. The seafloor locations are approximately 200 miles offshore and HD video links reached 20 Mbps.
