Underwater Broadcasting

Live broadcast with a smartphone through YouTube of large group dive to set up a new Guinness World Record: “Most Viewers of a Live Shipwreck Dive.” Live images were broadcast from the sea bed to a boat on the surface, and from there onwards. Challenges involved transmitting from a depth of 20 meters, which involved a cable three times as long; connection of proper cabling to smartphone and transmission equipment; cameras and equipment battery life; high-definition broadcasting; harsh underwater environment. HDBaseT enabled the transmission over 60m of Cat6 cable, from a smartphone to a boat on the surface.
