For broadcasters who wish to benefit from the cost savings and reliability offered by SureStream but don’t want to invest in new Codec hardware, the APT SureStreamer is the perfect solution.

APT SURESTREAMER can sit in front of any existing single port IP Audio Codec from any manufacturer enabling the use of widely available, affordable IP connections to deliver broadcast-grade audio with no interruptions, glitches or drop-outs. It continues to provide a seamless audio stream, even when one of the contributory links suffers a total Loss of Connection.

APT SURESTREAMER can also be deployed as a multicast or multiple unicast node to reduce Telco costs significantly by migrating the stream  replication function away from the source encoder and closer to the decoding devices.


Audemat ScriptEasy Powerful Performance

  • Increases link reliability by stream diversification
  • Connects to IP Codec using UDP/RTP
  • Data agnostic – streams any data (audio, video, EDI-data and other real-time, mission-critical data)


Audemat ScriptEasy Powerful Control

  • Intuitive WEB GUI for ease of use
  • SNMP monitoring included
  • AUDEMAT ScriptEasy enabled, allows automated actions


Audemat ScriptEasy Powerful Savings

  • Ensures “Always On” redundancy
  • Cost savings when used with public internet
  • APT SureStreamer deployed as a node can reduce Telco costs dramatically


  • Enables affordable upgrade to cutting-edge IP technology
  • Connects to standard IP audio codecs from many manufacturers, as long as they use UDP/RTP
  • Connect via 2 wired connections OR
  • Connect via both wired & WIFI links
  • Ensures “Always ON” Redundancy
  • Enables cost savings with use of public internet
  • Algorithm-agnostic unit - does not matter what coding scheme used
  • Uses tried & tested, multiple award-winning APT SureStream Technology


The Principle of Stream Forwarding

APT SureStreamer  uses SureStream technology to create multiple streams for increased reliability. These streams are then forwarded to the destination codec where a flawless, single stream is received.

SureStream for Broadcast Quality Audio over IP

SureStream technology is a revolutionary innovation from APT that enables broadcasters to use inexpensive IP links and still maintain professional broadcast-grade audio quality and reliability.

It delivers 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.

Advanced Telemetry & Remote Control with ScriptEasy

ScriptEasy is the revolutionary facility control software developed by WorldCast Systems to give users the power and flexibility to create “Smart” sites; ones that can automatically take action to correct any critical errors that affect operations.

Featuring an intuitive Graphic User Interface (GUI), ScriptEasy incorporates GPIO functions, serial communications, logic operators, live user inputs, timers and more. This allows the site operations to be “scripted”, to allow evaluation of multiple parameters and even automatically engage backup systems, while simultaneously alerting relevant technical personnel.

Remote Hub application

Remote Hub describes the wireless ingress from a mobile unit to the APT SureStreamer and the network. It allows the talent to roam within the range of the wireless coverage to conduct interviews etc. The APT SureStreamer acts as private Wi-Fi access point for the mobile unit and connects the talent’s device reliably with the connected network utilizing the APT SureStream Technology.

SureStreamer Data-Node to reduce Telco costs

This application is for broadcasters who wish to save on operational costs by utilizing a Telco data center or other POP close to the broadcasting area. The studio streams only one pair of component streams into the remote data center. In the data center, the APT SureStreamer receives the program stream and multiplies it using Multicast or Multiple Unicast technology. Using the APT SureStreamer as a node to migrate the Multicast function closer to the decoder significantly reduces the long haul Telco costs.

«[With SureStreamer], we now have a system that can deliver better reliability than an expensive fiberoptic line, and is using a mere cable modem and DSL line.  Instead of spending $1500/month we’re spending more like $200/month for both connections.»
