Buffering rate during 4 hours
Being a CDN vendor for Vitrina TV, we see the critical thing for keeping QoE at the highest level is the ability to detect video download bottleneck and the ability to timely change the way a particular device is downloading the file. When every video player has multiple live connections with multiple distributed sources, there is always a lightning-fast way to switch from a bad source to a good one, and avoid the download slowdown which usually causes buffering.
With Vitrina TV we noticed statistically that viewers' devices are able to download the video several times faster from the other devices in a distributed cloud than from the CDN! If a viewer has a set of active channels to download from, the chances of buffering fall 50%.
6 bitrates from
350 Kbps to 3.8 Mbps
With Teleport Media the chances for buffering fall 50%
To prevent buffering, an ABR mechanism of a videoplayer switch to a lower bitrate, finding the one that is optimal for current bandwidth of user.
Thanks to multiple traffic sources provided be Teleport Media, it is possible to maintain higher download speeds even if a user experience playback issues. An ABR have to make less jumps down to find a new balance.
With the same client, viewers that are connected with P2P network in case of switching lose only 18% in average bitrate compared to 35% loss of users connected to CDN.
Teleport Media reduces bitrate switching depth by half
