More Efficient, More Reliable, More Entertaining

The Digital Fountain® ToughStream solution allows IPTV operators to guarantee a perfect viewing experience to their customers, resulting in increased customer satisfaction and reduced operating expenses. Disruptions in the video stream result in a negative quality of experience for IPTV consumers. These disruptions cannot be anticipated since they are caused by any number of environmental and mechanical events such as in home appliances, electrical public transport networks and poor in home wiring to name a few. DF ToughStream guarantees a perfect viewing experience by protecting against any disruption in the IPTV video stream regardless of the root cause of those disruptions leading to a perfect, uninterrupted viewing experience.


The Digital Fountain® ToughStream Solution delivers entertainment-quality audio/video regardless of network conditions

DF ToughStream offers operators an easily deployed software solution that can be incorporated into any IPTV network. Any packetized stream can be protected using ToughStream, regardless of media type, encoding format, compression, data rate, or the use of DRM or encryption.




DF ToughStream Benefits:
Guarantees Quality –ToughStream ensures that video streams are delivered with the highest quality over broadcast and video on demand (VoD) networks.
• Increases Customer Satisfaction - ToughStream guarantees that IPTV consumers experience the highest possible QoE the number one driver of customer satisfaction.
Lowers OPEX - ToughStream guarantees the quality of the IPTV video stream therefore reducing both the number of complaints into the call center and the number of home visits.
Cost Effective Solution – ToughStream is a low impact overlay solution that does not require complex hardware implementations or fundamental changes to the network architecture.
 
Accepts More IPTV Customers – ToughStream reduces bandwidth limitations IPTV networks require for video services thereby allowing operators to accept customers on previously disqualified noisy broadband lines.
 • Drop-in Integration – ToughStream deploys directly into any IPTV environment regardless of video encoding, encryption, STB, middleware or network architecture. The original source stream is unchanged allowing multi-vendor STBs and line by line protection.
Best in Class Performance – ToughStream provides IPTV operators the highest levels of protection for the lowest network and CPU resource cost.

     

Technical Overview:

Digital Fountain’s (DF) ToughStream™ is a portable, scalable, and flexible solution that enables highly-efficient and reliable streaming transport over impaired IP-based networks. At the core of ToughStream resides DF Raptor™ Forward Error Correction (FEC) technology.DF Raptor is the leading application layer FEC technology; it has been adopted by IPTV and cellular operators, and endorsed by industry standards worldwide.


Solution Overview:
The ToughStream™ solution consists of a software Server Client pair. The Server software, which can be installed on most standard hardware platforms, is placed in a Video Headend, and the Client is placed as a library in a Set Top Box (STB).

Server Software:
The ToughStream™ Server receives and transmits the original source video stream packets unchanged. A protection process is initiated on receipt of the source stream, allowing repair packets to be generated and injected into the network on any address and port to be received by the client.

Client Software:
The ToughStream™ client receives the original video stream and any lost packets are recovered using the received FEC protected repair packets. A clean stream is then presented to the decoder and application.
