The IP-AVMixer project is an evaluation project partially funded by a grant obtained in the competitive VALUE 2010 (AGAUR/ACC1Ó). The development of this project is done jointly with the Audiovisual Unit.

The convergence of the audiovisual industry and the Internet is causing a revolution in traditional methodologies and processes. In this context, the production of video and audio is an area that has yet to evolve. Production has traditionally been done by dedicated non scalable hardware, with high costs that could become unaffordable, and requiring dedicated inflexible infrastructure.


The aim of our project is the implementation of an IP production system (which we call IP-AVMixer), with the capability to mix and switch audiovisual signals from multiple IP standard formats. The IP producer is intended as a convergence point between the switching matrices and the video mixers, which thanks to greater flexibility will increase the flexibility in production processes, necessary in these days where business competitiveness can be the turning point in their survival.


With the support of the Ministry of Knowledge Economy and the Government of Catalonia:



The objective of this project is to develop a system (IP-AVMixer) capable of switching and producing real-time audiovisual content over any IP network infrastructure, and to validate its commercial viability. The project concept has been technologically validated in previous projects, but adaptation and optimization is needed in order to perform the specific function proposed in a competitive manner.

The IP-AVMixer may be a possible either an alternative or a complement to existing switching platforms and audiovisual commutation/production audiovisual infrastructures, which are based on hardware switching matrices and video mixers (which work with standard video interfaces) and a specific dedicated wiring that transports audiovisual signals from the place where the catching up is done to the switching matrix.

From a technological point of view, our system will merge/integrate the virtues of new media formats (HD, SHD, 3D, etc.) with new-generation IP networks. The IP-AVMixer will adapt the standard audiovisual signals (HD-SDI, SDI, etc.) to have them transportable via a conventional IP network infrastructure, and will provide the functionalities originally associated with switching matrices and audio/video mixers.


With this product, customers will have the opportunity to reduce costs related to production function, taking advantage of existing IP network infrastructure for sending signals from different sources, reducing investment in equipment and infrastructure of audio and video.

Working in IP environments the usability and flexibility of resources can increase, and the tasks of implementation in small and medium events simplify.

The use of such platforms for audiovisual signal management has important advantages over the wide range of existing mechanisms in the market. On the one hand it presents a user-friendly architecture, where most of the management tasks are automated and facilitate the management of processes prior to distribution (broadcasting or streaming). However, it allows the implementation of high availability and high scalability that can be adapted perfectly to the needs of each client, offering appropriate solutions not only from the functionality point of view but also in terms of price.

Providing audiovisual content over the IP network, and giving that there is sufficient bandwidth, we have the flexibility to route/receive video content both local and from other sources that may be distributed geographically. Reduction of logistics costs may be one of the biggest advantages of the proposed solution.

Having the possibility to adapt the bandwidth and considering the robustness of the system against network problems, the user has extra security that his or her content will reach where necessary maintaining a minimum level of quality according to the different types of content. In addition, the proposed platform allows recording both the final product and the different sources involved in each case, giving users the ability to post-produce the contents in order to improve beyond the live broadcast.

Finally, highlighting the modular design in which this platform is based, it allows us to continue developments in the system as the market evolves, incorporating new formats (interfaces), codecs or processing strategies that improve the subjective quality of the content, giving a significant improvement to the system efficiency in comparison to existing solutions in the market.
