A flood of 360-degree cameras have entered the market, ranging from the Ricoh Theta through various contraptions build from GoPros to specialised surveillance cameras. Most of these cameras require a lot of offline-post-processing before a 360 video that has been converted into the so-called equirectangular format can be downloaded, for example through YouTube.
But a few cameras provide live streams, and this is provides a great opportunity for viewers. With just a single camera installed at an event, the viewer can take control over what they see at any given time, using pan-tilt-zoom on their mobile phones while watching the live stream. Perhaps they can also jump a few seconds back and see another part of the view.
This thesis aims at investigating algorithms for reducing bandwidth waste while achieving short delays in streaming to Android and iOS mobile phones.
