Area description

The Audiovisual Area works on different research, development and innovation areas related to the transmission and visualisation of multimedia contents applied to the media, culture and creative industry sectors.

By means of participation in diverse national and international projects and through a strong collaboration with different industrial partners, an effective improvement has been made in the state-of-the-art in the following areas: content distribution systems, videoconferencing, ultra-high definition systems and mixed reality applications.

Our short and mid-term work is focused mainly on the following R+D+I lines: content management, context aware content adaptation & delivery, content transmission in heterogeneous networks, ultra-high definition, immersive environments and augmented reality applications.

Research Lines

Description and goals

The continuous evolution of communication and computing infrastructures and display devices play a key role that have a strong impact on the underlying content distribution and visualisation systems. The Media Networks group is researching techniques and methodologies to combine global and local content delivery networks (local/global CDNs) and scalable and adaptive video codification and packaging systems (AVC, HEVC, MPEG-DASH, WRTC).

The main goal of this research line is to study and develop efficient software systems to manipulate digital media over the network by using and aggregating the key industry standards. Modular server side services are gaining in relevance as the Cloud Computing Era is becoming a reality. The Audiovisual Area has been researching core services easy to orchestrate that are suitable in this cloudified context, where the delivery and scalability are and will be major objectives.

Knowledge progress

The Research Line has acquired relevant knowledge about streaming standards such as MPEG-DASH and more specifically about MP4 encapsulation possibilities. The team significantly improved its background on image manipulation (RGB crop, resize, overlay, etc.) and process parallelisation (using C++11). Finally, with regards content delivery techniques such as content caching or dynamic content adaptation, the researchers gained knowledge in order to perform stable and robust live media streaming.

Description and goals

This research line works towards the creation of new interactive services in mobile devices. The fast evolution of mobile devices, the daily improvement in their communication and processing capacities, allow us to increase the demand for services which, only a few years ago, were limited to dedicated infrastructures. 3D processing and location-based services are the main research focus of this research line, and in particular, we are addressing augmented reality and the cultural heritage sector as the main technical and market sectors.

  • 3D rendering
  • thin rendering on mobile devices
  • augmented and mixed reality
  • location based services
  • micropositioning
  • cultural heritage.

Description and goals

Digital technologies offer great opportunities for culture, creativity and social innovation.The confluence between technical infrastructures, technologies and the cultural and creative sectors allow us to explore new fields of research and services. The mobile sector is undeniably the driving force of new applications and services. From this research line we focus on the creation of advanced applications and the cultural sector is our main market target. We believe in cultural heritage as the basis of new educational and touristic services and it can be enjoyed from different, new and advanced perspectives, using pervasive gaming technologies and enhancing existing cultural infrastructures.

Knowledge progress

The Audiovisual Area team has acquired relevant knowledge about digital library standards and aggregation processes, whilst increasing the level of expertise on eCulture and social innovation projects and services. We have also enhanced our knowledge and strengthened our collaboration with the local creative industry through projects like Specifi and FiContent 2.

I2CAT’s position in the Living Lab and user-centred design sector has been strengthened through the tasks performed in partnership with several local entities and organisations, such as Citilab, Neàpolis or Guifinet. Among these, of paramount importance is the ongoing collaboration with ICUB and Generalitat de Catalunya in the Barcelona Laboratori project, with several actions performed in the framework of the Specifi and FIcontent 2 projects. This ongoing cooperation places i2CAT at the core of the local user-centred innovation ecosystem, and reinforces i2CAT’s leadership in this area.

Market Approach

The Media Networks research line is mainly focused on delivering research and development services as well as the creation of pre-commercial products for the audiovisual and broadcasting sector. These services and products are oriented to facilitate and reduce the cost of IP-based video and audio transmission, and cloud-based processing services. During 2013, different commercial initiatives and projects were launched in collaboration with private and public companies as well as with other research centres. Our main activities at a business level were the development a new cloud-based IP-Mixing solution, in collaboration with ADTEL (, which will be launched during 2014; and the development of an mpeg-dash packager and the adaptation of an existing and open source CDN project to deliver mpeg-dash over hbbtv 1.5 compliant devices, in collaboration with TVC (

During 2013 we collaborated to a large extent with the Culture Department of Generalitat de Catalunya, and specifically with the museums: the mNACTEC ( and the MAC-Empúries (
