8 OTT
8.1 Introduction
OTT or Over The Top refers to video, audio and other media services delivered
directly to the user over the Internet, for Video on Demand or Live broadcasting.
There are different standards being used to deliver OTT services. MPEG-DASH
and HLS are the most popular. All OTT protocols address the fundamental
problem of poor viewer tolerance to disruption or buffering during video play out
caused by the naturally changing network conditions of the Internet
To solve these problems, the OTT servers provide the same audio / video
fragments in different resolutions and bitrates so the user can select one or the
other depending on the network conditions. This helps to decrease the annoying
effect of buffering.
To know server's availability is important, so the client media player can select
the right quality at a certain time. This information is contained in the HLS
MANIFEST file or in the MPEG-DASH MPD file (Media Presentation Description).
The meter can retrieve and display the information of these files and download
the selected content by segments and also it shows the download bitrate in a
graph.
