SmartStream PLUS: The industry standard for broadcasting over the public internet

   --------- SmartStream logo

As an IP audio pioneer, Tieline was the first major codec manufacturer to integrate SmartStream features such as Automated Jitter Buffer management, Forward Error Correction (FEC) and error concealment techniques in all IP codecs. These features dynamically respond to variable conditions over unmanaged IP networks like the public internet to ensure reliable streaming.

Now SmartStream PLUS has revolutionised IP broadcasting by delivering the rock solid and reliable STL-grade audio quality you would expect over a T1/E1 link by using inexpensive unmanaged IP networks like the internet for STLs, audio distribution and remotes.

How is this possible? Connect two inexpensive IP links to codecs with SmartStream PLUS and stream simultaneous redundant data streams from dual Ethernet ports and deliver seamless redundancy when streaming over IP.

Tieline can show you how an investment in new codecs will pay for itself in just a few months by using SmartStream PLUS over inexpensive IP links to transport STL-grade, high fidelity audio at a fraction of the cost of synchronous leased lines and satellite links. With SmartStream PLUS:

  1. The codec can stream simultaneous redundant data streams from both Ethernet ports and deliver seamless redundancy by switching back and forth, without loss of audio, from the nominated primary data link to the backup link if one fails and then subsequently recovers. Note: Use IP links from two different IP network providers for optimal redundancy over mission critical STL connections.

  2. When multiple redundant audio streams are sent, the decoding codec automatically reconstructs audio into a perfect single stream on a first packet arrived basis to ensure audio integrity.

SmartStream IP Delivers ...

Some other manufacturers charge thousands of dollars for IP management software like SmartStream as if it's an optional extra, however Tieline believes high performance and rock-solid reliability is an essential part of each and every broadcast, and therefore delivers its renowned SmartStream IP management software for free.

SmartStream PLUS delivers an additional layer of STL-grade redundancy and is available as standard in Tieline Genie STL, Genie Distribution, Merlin and Merlin Plus codecs. In summary, SmartStream PLUS delivers:

  1. Huge cost savings: use SmartStream PLUS over inexpensive IP links to transport rock solid, high fidelity audio at a fraction of the cost of synchronous leased lines.
  2. Continuous rock solid reliability: stream simultaneous redundant data streams and get seamless redundancy if a connection is lost.
  3. High fidelity audio: Tieline's renowned suite of high-quality algorithms will all work using SmartStream PLUS.

These combined measures ensure Tieline is capable of offering an IP solution, in which the payload capability of your network infrastructure is the only limitation to successfully distributing large numbers of audio streams economically and efficiently across broadcast networks.

Hear the SmartStream Difference...

It is not unusual for wired internet connections to experience up to 3% packet loss, while wireless IP audio connections can experience 10% or more! With SmartStream features such as Forward Error Correction (FEC) and automated jitter buffering, Tieline IP audio codecs can withstand significant packet loss over wired and wireless IP connections and maintain continuous high quality audio.
