The adoption of the Digital Terrestrial Television (DTT) represents the most outstanding step towards a full digital conversion of the television system and paves the way for further evolution.

The digitalization of the TV signal transforms the traditional television device from a channel tuner into a real multimedia hub and paves the way for the convergence of different platforms. This process determines a communication environment that integrates various types of portable devices (mobile phones, smartphones, tablets, etc) and fixed devices (set-top boxes, gaming consoles connected to digital TV, personal computers, etc).

Traditional transmission of TV signals (terrestrial, cable and satellite) coexist with interactive models that exploit the broadband data transmission (mainly on xDSL today and, in the future, more oriented towards the fibre optics).

The fast-growing use of Internet and the increased availability of broadband access have paved the way for the use of TV platform over IP, that is, an interactive digital platform that uses the Internet as a transmission channel for television contents.

The most interesting trend is perhaps the advent of new, advanced features in the TV sets currently entering the markets: flat screen, high definition, 3D, connectable TV devices.

Even though the available TV contents today are still in standard definition, the number of HD-enabled TV sets is a quarter of the total number of installed devices, and represents 100% of 2011 sales of TVs screens over 32”. A growing trend is also represented by Net TV, that is, television devices with direct IP connectivity and enabled to receive OTT (Over The Top) contents. In other words, High Definition is replacing - with regard to the availability of TV devices - Standard Definition.

FUB carries out research on the evolution of television service and the experimentation of alternative TV platforms. In this framework, several significant research programshave been performed(supported by experimental tests carried out at ISCOM laboratories) on the potential of TV over IP in view of the use of TV as a tool to access the Internet.

In addition, FUB was involved in the design and coordination of an important formal test campaign for the evaluation of high and ultra-high resolution video. This activity allowed MPEG to start the standardization of the HEVC (High Efficiency Video Coding) image compression algorithm.

    MPEG (ISO/IEC – JTC1/SC29/WG11)

In depth

Since 2004, FUB has been operating a digital TV Laboratory that is able to reproduce the whole value chain of digital television: generation, processing and broadcast of programmes and services.

  • MONITOR DTT monitoring actions - Evaluations of the User Experience through Digital Terrestrial Television
  • TV capabilty over IP
  • Advanced Multicast processes

In the framework of the HD Forum Italia, FUB plays the role of neutral guarantor for strategic choices in national technical norms on HDTV, contributing to technical specifications and communication activities on High Definition features, as well as to the design of deployment scenarios.
