The Media Server
Updated: May 1, 2018
Discussing the role of the media server in our workplace.
What is a media server?
I was first introduced to the media server back in 2002 following a chance demonstration. I knew nothing about video, yet was captivated by the seemingly endless creative possibilities it offered to manipulate images in real time, in a way which I had not seen previously.
Context within the entertainment industry
For the purposes of event technology, a media server is a playback mechanism for video content, sometimes incorporating audio and live video as well, with the unique ability to manipulate this imagery with a graphics engine in real time.
Lighting and Video Convergence
Many media servers have been designed by companies manufacturing lighting products. They are easily controlled by lighting protocols such as DMX and ArtNet, although many work equally well as standalone products, or can be controlled by MIDI or SMPTE timecode.
Professional software on consumer hardware
Never before had consumer level computing been used and relied upon in such a way on our productions. It’s still true today that the off-the-shelf computer element of the media server can be far less expensive than the professional video signal converter it is connected to.
Pixel Mapping
Another exciting development came in response to the explosion of LED lighting fixtures which were very channel heavy and processor demanding. One solution was to outsource this processing to a media server.
Uses
Today media servers can be found controlling lighting and video elements of large scale touring productions, primetime television programs, West End and Broadway shows, and more. They can also work as interface products, receiving and sending commands over various protocols.
Hardware
As computer hardware has evolved, the media server sector has benefited tremendously. With the latest graphics cards and solid state hard disc technology, they can generate multiple video outputs simultaneously and process an impressive array of effects.
Content
Good imagery is essential. Stock footage and bespoke content design houses are reliable sources of material. Licensing content for the intended use is vital.
The future
As advances in computer hardware move forward, so will the media server. 3D video mapping is well and truly under way. Watch this space.
