APT WorldCast SureStream

Quick details


Perfect Audio over an Imperfect circuit


SureStream Technology from APT enables broadcasters to use inexpensive IP links and still maintain professional broadcast-grade audio quality and reliability, delivering the audio quality and reliability you expect from a T1/E1 link at a fraction of the associated cost.

APT SureStream Technology also offers the added benefit of “Always-On Redundancy”. With APT SureStream technology, you can save thousands on your audio transport bills and still offer your listeners the highest quality sound.

SureStream on APT Multi-Channel IP Codec

Whilst SureStream is based on Redundant Streaming technology SureStream offers much more than just duplicate streams employing a number of proprietary techniques that optimise the delivery of all streams throughout the network and an advanced re-sequencing engine that produces one perfectly seamless, reconstructed stream from the multiple streams received. Perfect audio from an imperfect network!

SureStream works well on a single IP link for impromptu remotes or outside broadcasts but, for mission-critical Studio Transmitter Links and audio contribution or distribution, we recommend utilising two or 3 links from different providers.

SureStream Dual Port Configuration




  • Save Money: You can save up to 90% on the cost of your audio transport bills by replacing your synchronous or managed IP Links with the public internet. With DSL charges typically costing from 5-10% that of a synchronous link, the potential savings are so significant that it is possible to achieve a return on your investment in under 4 months!
  • Deliver High Quality Audio: No need to sacrifice audio quality for the sake of cost savings. SureStream enables you to maintain consistently high audio quality with no drop-outs and no jitter.
  • Keep Delay Consistent : Maintain the delay at a consistent level, particularly useful for remote broadcast applications and local content insertion.
  • Relax! SureStream offers you the same level of up-time and reliability as a ‘five nines’  Telco service. You are protected not only from drop-outs and glitches but also from a complete loss of a single connection!
