Two names
HDOnline is often shortened to HDO, and both names lead to the same site. The logo shows the letters HD, a gold ring with a play button for the O, and the word online.
HD
HD stands for high definition: pictures of 720 or 1080 lines, and today often 4K. Every title on HDOnline carries a small gold HD badge on its poster.
Online
Online means streaming: every title plays on an official service in your browser, on your television or on your phone.
