APT SureStream is the best, most widely used and established technology for robust, low cost, and low latency audio / video transport over IP.
This innovation enables broadcasters to deliver the high professional broadcast-grade audio/video quality you expect from a T1/E1 link, but 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.
You can save most of the cost of your network services by replacing your synchronous or managed IP links and expensive satellite uplink services with the public Internet. Since the cost of DSL services typically ranges between 5-10% of the cost of a dedicated connection, the potential savings are so significant that your investment will pay for itself in a few months.
The quality of your transmission should not be sacrificed for the sake of cost savings. With SureStream, you can maintain consistently high quality without dropouts and jitter.
For professional content delivery, it is not acceptable for the signal delay to vary or to drift. The ability to maintain the delay at a consistent level is particularly useful for remote broadcast applications and local content insertion.
SureStream offers you the same level of uptime 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 connection!
SureStream not only enables significant cost savings by using affordable public internet links rather than expensive MPLS or Satellite links, but it also ensures flawless audio and video quality and reliable distribution thanks to its "Always-On Redundancy."
What do we mean by "Always-On Redundancy"?
At a basic level, SureStream is based on Redundant Streaming technology but SureStream offers much more than just duplicate streams. SureStream employs a number of proprietary techniques that optimize the delivery of all streams throughout the network and an advanced resequencing engine that produces one perfectly seamless, reconstructed stream from the multiple streams received. Instead of transmitting one copy of the data (audio/video) between the encoder and the receiver, SureStream
sends multiple copies across different paths. This ensures resilience and the optimal quality of the reconstructed stream.
Perfect content delivery from an imperfect network!
For broadcasters who are already using another codec but wish to benefit from the cost savings and reliability offered by SureStream technology, Virtual SureStreamer is the perfect solution.
Virtual SureStreamer is available as a single appliance installed on WorldCast industrial Linux, for example in front of your existing codecs. At a larger scale, it can be installed as a multi-node architecture including WorldCast High Availability.
Deployed as a multicast or multiple unicast node, it significantly reduces Telco costs, by migrating the stream replication function away from the source encoder, closer to the decoding devices. Even more versatile, with SureStreamVPN you can produce your complete radio show from anywhere live, with full control over your media and advertising ingests from the studio.
APT IP Codecs are all compatible with SureStream technology through a simple software upgrade.
Feature-packed and cost-competitive, the APT IP CODEC offers the most complete set of IP features ever included in APT’s extensive range and features both our revolutionary “SureStream” technology and intelligent ScriptEasy scripting. This next generation IP audio codec also offers a wide range of algorithms as standard on a solid DSP platform with dual IP ports and redundant power supplies.
In line with the market’s transition to offer both hardware and virtualized solutions, the famous APT IP Codec is now available as a software solution – the Virtual APT IP Codec.
This shift to virtualization is strategic in reducing the amount of equipment to purchase, thereby offering important upfront and operational cost savings to broadcasters.
It supports APTmpX, the highest quality MPX compression algorithm, and SureStream, for robust, low cost, and low latency transport over IP.
"SureStream technology has made possible something that was conventionally assumed to be impossible: having a high quality, real-time audio link over the open Internet."
