S ky-live.tv is a website that broadcasts real-
time astronomical occurrences. It is the result
of collaboration between Ciclope Group, at
the Technical University of Madrid’s Montegancedo
Astronomical Observatory, and Shelios, a nonprofit
organization aimed at promoting and disseminating
lectures, courses, exhibitions, and the results of scientific
expeditions to the general public. The two organizations
share a desire to make astronomy more accessible to
universities, students, and anyone else who is interested.
With Sky-live.tv, it’s possible for anyone — from students
and researchers, to armchair astronomers — to experience
astronomical expeditions on their screens. Expedition
members analyze the data and contribute to live
broadcasts, and then the media content and results are
distributed free under a public-domain license.
While Sky-live.tv’s original solution served the purpose
initially, their software and setup was cumbersome, and
could not manage a peak of several thousand concurrent
connections. Additionally, network throughput was a
concern. Sky-live.tv also implemented a system using a content
delivery network (CDN) through a third-party provider, but
that solution very quickly became too expensive for its
Challenges Finding a cost-effective way to broadcast live astronomical
phenomena over the Internet to large and geographically
dispersed audiences on any device.
Streaming live video from disparate, often remote sites
around the globe.
Robust Wowza Media Server software enables smooth,
reliable delivery to audiences on any screen.
Wowza Media Server on Amazon EC2 cloud provides
flexible capacity for large-scale streaming.
Compatible with multiple platforms, and off-the-shelf
hardware, and software to eliminate compatibility issues,
expand reach, and simplify setup.
Customizable with a variety of free and premium (paid)
Wowza AddOn packages.
Urko Serrano, Ciclope Group IT engineer , commented “the
fact that Wowza Media Server is compatible with so many
different media codecs and formats is quite useful in our
research projects because we can test different software
prototypes without worrying about compatibility issues.”
Sky-live.tv turned to Wowza Media Server® 2 software to
make its streaming-video operation functional, scalable,
simple, and cost-effective. In just a few steps, Sky-live.tv
could adapt the size of its solution on the fly using Wowza
Media Server on Amazon EC2 cloud to fit the size of the
audience at any given time with high reliability.
Sky-live.tv also customized its solution with Wowza’s Push
Publishing AddOn to enable easy delivery of its live stream
to partners that maintain their own CDN solutions.
Finally, because Wowza Media Server 2 supports a wide
range of input streams with different media codecs and
formats, Sky-live.tv could use all of its various hardware
and software encoders to send live streams from expedition
sites to its media streaming infrastructure.
