Convergence TV is a collaborative research project dealing with the development, validation and commercialisation of a new distribution solution for linear and non-linear TV contents. It uses both broadcast (terrestrial, satellite) and broadband (OTT) in a convergent way, using IP protocol stacks in both distribution schemes.



It proceeds in two major steps:

A first step targeting the markets adopting the ATSC North American broadcast system (Korea, Nort America). The solution is designed to comply with the brand new ATSC3.0 standard.

A second step targeting the markets adopting the European broadcast DVB standards (France, Europe, Asia, Africa). The solution relies on adapting the full IP solution to the DVB basis.


In a first step, Convergence TV aims to develop, experiment and commercialize a solution for distributing TV contents (linear and non-linear) making a convergent use of both broadcast and broadband networks. The proposed solution is based on a unified all-IP architecture, using open standards coming from the OTT world (DASH or MMT), adapted to the broadcast world and replacing the aging transport standard MPEG-2 TS. Other possible candidate technologies such as the emerging MPEG-CMAF file format may be looked at, with the same target for a convergent, unified approach for both the broadband and broadcast distribution schemes.



In a second step, the project will implement this convergent IP approach in the context of the new ATSC3.0 system, which made similar choices.

In a third step, the project will propose to port the all IP approach to the DVB systems, which still use the MPEG-2 TS.

By doing this, the project consortium targets two application markets:

  • One ATSC export market using the new ATSC3.0 standard: Korea and North America, starting as soon as early 2018,
  • One Europe and rest-of-the-world market using future convergent DVB standards, in medium and long term views (2020 and beyond).

The project consortium comprises five industrial partners, two academic partners and is supported by two “validating partners” (content editor, satellite operator). It constitutes a complete ecosystem, at the best level and already strongly turned toward exportation.



TeamCast is a leading supplier of digital modulation technologies for terrestrial TV broadcasting and satellite transmission for TV and broadband Internet. With its headquarters and research centre in Rennes (France) TeamCast is also present in the USA (NY) and Singapore, and takes 80 to 85 % of its revenue from exportation.

The role of TeamCast in the project is to develop technology bricks dealing with the Physical Layer (DVB-T2, DVB-S2 and ATSC3.0 modulators), to bring its expertise in implementation, system integration, system validation, and to make liaison with some standardisation bodies (ATSC, DVB, FoBTV). TeamCast is also the project coordinator.


ATEME was founded in 1991 as a design house for video compression. Shortly afterwards, ATEME introduced a complete video delivery solution. In 2014 ATEME announced its initial public offering at Euronext Paris.

ATEME has and will continue to transform video delivery. ATEME was the first to market with a 10bit 422 solution, the first production ready HEVC & HDR, and recently, the first true video delivery NFV software solution, designed to lead and win the service providers transition to video datacenter. To complement our cutting-edge technology, ATEME has partnered with leaders such as Intel, Apple and Microsoft to create the best in class video delivery solutions.

ATEME is a leading member of forms, and organizations, such as the DVB and SMPTE. ATEME actively participated at the ITU/MPEG in the standardization of HEVC in 2013. In June 2014 ATEME joined the Alliance for Open Media to help develop an open and royalty-free video codec.

ATEME headquarters are Vélizy-Paris, with worldwide support and R&D offices in Rennes, Denver, Sao-Paulo and Singapore.  With a commercial presence in 14 countries, ATEME is 200 employees strong, including 100 of the world finest R&D video experts.  In 2016 ATEME served close to 200 clients worldwide, generated 31% of year on year growth with revenues of €37.5 million, 91% of which was from overseas, and 6% net profit.


ATEME will bring its expertise on video compression for new upcoming video headend based on IP delivery. It will contribute to the implementation of an hybrid delivery system with high flexibility and fine-tuned broadcast broadband synchronization.

​Motion Spell is a young innovative company started in 2013 by multimedia experts. The company has two main fields of activity.
First Motion Spell acts as the commercial arm of the GPAC Multimedia Open Source Framework under the name « GPAC Licensing ». GPAC is a powerful worldwide project, established in 1999 in NYC, dedicated to the development of rich-media, video encoding and broadcast technologies.
GPAC Licensing provides a business friendly licensing model that extends the commercial possibilities of the GPAC Open Source Software, helping people transport multimedia data in the right format. GPAC OSS is the reference standard for the MP4 file format and was chosen by industry leaders such as Youtube, Sony, x264, Philips, Cisco, Ericsson, General Motors, Fox, and many others.
GPAC Licensing offers extended commercial development licenses as well as ready-made technology solutions such as Firekast (a service to make video accessible to any developer), Signals (a video processing framework to build broadcast quality products within days), or Abstract (a revolutionary compliance engine to analyze and certify your content), which are GPAC Licensing subsidiaries.
Motion Spell is based in Paris.

Within the framework of the Convergence TV project, INSA-IETR will extend its studies
on Digital Video Broadcasting systems which is one of the key items of the SYSCOM team of IETR.
The main objective of this work will be to improve the energy efficiency of future networks, including digital television broadcasting networks.
More precisely, « Green  » solutions will be developed based on the optimization of algorithms allowing to
reduce the dynamics of the transmitted OFDM signals measured by the Peak to Average Power Ratio (PAPR) in order to decrease the energy consumption of TV transmitters. These studies
reinforce the expertise of IETR in the field of broadcasting systems in general. Furthermore, specific algorithms to reduce the dynamics of DVB-T2 and ATSC3.0 signals, offering a very good performance/complexity trade-off
will be optimized.
In addition, INSA-IETR will contribute to the modeling and optimization of the hybrid network in order to
operate in a complementary way the broadband and broadcast networks for the broadcasting of linear and non linear services
including the study of off load scenarios.
