Africa, in general is still drawn back in terms of ICT
infrastructure and broadband network. Companies and some
governments are gradually trying to setup up necessary
infrastructure, but the norm here, is that we have relatively
slow internet speeds especially when compared to the
developed nations.
With this in mind, a group of South Africans developed video
streaming technology designed to specifically to work in low-
speed internet environments like ours. The first app to
implement this technology is called Tuluntulu (A Zulu word for
“stream”), free and available for Apple and Android phones.

How does this app work?

This is the interesting part. They say it works on a platform
called Adaptive Real-Time Internet StreamingTechnology
(ARTIST).
ARTIST makes use of algorithms to adjust the video quality to
available bandwidth. This means the rate at which a video
streams varies depending on the available bandwidth at the
time. This means you can adjust the quality of the video you’re
watching depending on your browsing speed.
ARTIST’s rate-adaptive technology makes buffering useless,
and ensures smooth video streaming. It automatically adjusts
the video quality to ensure the video stream won’t buffer or
break. A user can adjust video quality with a simple volume-like
button, allowing them to control their own data costs.
The platform was developed by a group of researchers and
engineers from the Council for Scientific and Industrial
Research(CSIR),in the University of Cape Town, and it’s being
commercialised by start-up company Tuluntulu.
The mobile app, offers 10 unique “TV-type”channels 24/7. The
user only pays for associated data costs. The new technology
is a boost and we hope its makes major impact in places where
accessible bandwidth is still a problem. It will be ideal for
content creators and advertisers, since it will be relatively
cheaper to use this app.
One major catch is that, streaming on slow network actually
reduces the quality of the video you watch.

How true is this?
