Introducing ProSTREAM

The Telos Systems ProSTREAM is a hardware-based audio processor and web stream encoder device in a 
compact 1U rack-mount chassis. The ProSTREAM will process and encode audio sourced from either rear-
mounted analog audio inputs, via Livewire IP-audio technology, or via optional AES/EBU digital inputs.

ProSTREAM uses Omnia Audio’s proven audio processing algorithms to balance the input audio to fit your 
program’s sound. ProSTREAM encodes the processed audio and muxes the companion real-time program 
meta data into a compressed web stream. ProSTREAM then connects to a streaming relay server instance or 
streaming service provider to deliver a rock solid packet stream for Internet clients.

FYI: MPEG License & Music Copyright

Musical compositions and sound recordings are creative works that are protected by the copyright laws 
of the United States (title 17, U.S. Code) and other countries. Under U.S. law, the owner of a copyright 
has the exclusive right(and may authorize others)to reproduce the work, use parts of the work in a new 
creation, distribute the work in whole or in part, and to publicly display or perform the work (including on 
web pages and through webcasting). With few exceptions, it is illegal to reproduce, distribute or broadcast 
a sound recording without the permission of the copyright owner. It is your responsibility to comply with 
the copyright laws of the United States and other countries in which you broadcast and to pay all applicable 
royalties to the copyright owners when you become a webcaster.

There have been recent amendments to the copyright law regarding webcasting of sound recordings. These 
new provisions allow webcasting under the terms of a statutory license, as a way to help webcasters get 
permission without having to go to each sound recording’s owner. The statutory license, however, has 
strict requirements that you must follow. Some of these requirements include the payment of license fees, 
limitations on the number of songs from the same album or artist that may be played in a three hour period 
(called the sound recording performance complement); a prohibition on publishing advance playlists; and 
a requirement to identify the song, artist and album on the website. There are other requirements as well. 
The Recording Industry Association of America provides quite a bit of information on copyright law as it 
applies to webcasting, and both ASCAP and BMI have created license agreements that they are willing to 
grant to webcasters that they believe conform to the provisions of the new copyright rules for webcasting.
