Highlighted Activities and Projects

Closed Project in November 2022

5G RECORDS

Rai experience in 5G-RECORDS EU Project

5G RECORDS (5G key technology enableRs for Emerging media COntent pRoDuction Services) is an EU project, part of the Horizon 2020 framework, which aims to investigate the exploitation of 5G technologies in the context of TV production.

 

Conceived from the synergy between media companies, network operators, equipment manufacturers and research bodies, the project focuses on the integration of already existing 5G components and the development of new ones, in order to evaluate their performance within three distinct scenarios representing the state-of-the-art in content production.

Activity within the Rai-LIS Project

AN AVATAR FOR ITALIAN SIGN LANGUAGE

Rai realized four virtual LIS interpreters, developed by adopting the latest computer graphics technologies and the use of innovative platforms.
This research activity will allows RAI to manage the entire process of generating new contents in LIS for future services for deaf people.

Progetto attivo dal 2018

Modeling and characterization of a GTEM cell

As part of a collaboration with Rai WAY, the electromagnetic behavior of an open GTEM cell at different operating frequencies (from 250 MHz to 1 GHz) has been analyzed, implementing an accurate finite-element model of the device. The analysis, conducted both from a simulation and an experimental point of view, has allowed to characterize this electromagnetic structure as to the field uniformity, a quality necessary to carry out field probes calibration or electromagnetic compliance tests.

Progetto attivo dal 2018

Early Warning System: an innovative system for satellite DTH transmission of alarm signals embedded in DVB-S/S2 signals

A new method to generate and transmit alarm signals to alert the population in the event of natural disasters, embedded in satellite TV transmissions has been devised by Rai-CRITS and proposed to DVB. The prototype developed in the project allowed us to test in the laboratory the effectiveness of the method and the backward compatibility with existing DVB-S/S2 receivers.

Experimental activity

5G Broadcast demonstration during the European Championships 2018

Rai-CRITS experiments of feMBMS (3GPP Rel.14) in Aosta Valley

Rai-CRITS, in collaboration with the Technische Universität of Braunschweig (DE), is testing the most advanced precursor of 5G-broadcast technology, the feMBMS (Release 14 of the 3GPP standard). The technology was demonstrated in Valle d’Aosta during the European Championships, held in Glasgow and Berlin from 2 to 10 August 2018.

Active project

Mitigation techniques of the interference generated in TV distribution installations by 4G/5G signals in the 700 and 800 MHz bands

The activation in the UHF band of 4G/5G Base Stations can have in some areas an impact on TV reception, especially in case of community antenna installations. The adoption of proper interference mitigation techniques, such as the insertion of specifically designed filters at the head-end of the distribution network, allows to mimimise the effects in most situations.

Active project

Recommender Systems for Audio and Video Contents

An investigation of the solutions to limit information overload for radio television media

The advent of the Internet and the proliferation of digital services have led to a radical change in the way people enjoy radio and television. The plethora of products, services and content available on the Internet has accustomed its users to interactivity, the ability to search and choose when and what media content to listen, transforming the traditional radio and television listeners into an active consumers, capable of expressing their tastes and preferences. Paradoxically, the vast amount of content available has created an informative overhead and created the problem of finding the most suitable content for each user.
Recommender Systems represent the technological response to the need of relevance. In this context, the broadcaster has the opportunity to evolve its communicative paradigm: in addition to broadcast its content, it can propose the most relevant to its users.

Active project

TV signals on ultra-wideband optical fibre networks

Optical fibres are now increasingly popular in telecommunications, due to their extremely high bandwidth, their very low attenuation, their complete immunity to electromagnetic interference and their reduced diameter and weight.
For these reasons, they are playing an increasing role in trasporting TV content, both for in-building TV signal distribution within the multi-service optical infrastructure, which is mandated in all new buildings (Italian Law 164, 2014) and for TV consumption via broadband networks, which will benefit from ongoing investments in FTTH (Fiber to The Home) architectures, where the fibre is terminated at each building. In Italy, network operators are launching massive optical fiber investment plans over the next five years, not only to cover the most densely populated areas (A and B) but also for less profitable areas (C and D).

Active Project

Personalized Linear Radio

Personalized Radio and the Hybrid Content Radio Framework

Personalized Linear Radio is based on the idea of replacing part of the audio of linear radio with personalized and user-specific audio content. Audio content can be downloaded from the Internet or from other sources. The context can be the profile of the listener, her mood and activity she is doing, her position, the weather conditions, and all the factors that contribute to characterizing the listener’s status. The ultimate goal of the service is to improve listeners’ user experience, giving them targeted content, while optimizing the use of network resources.

Active project

QC – Quality control

Audiovisual quality control

In the era of digital media files, quality control is a key activity in the production process and public communication of audiovisual content. RAI Research and Technological Innovation Center is involved in various contexts related to this issue. Among these we have all the controls of file format compliance with standards, a study also conducted in EBU, the quality control in the context of archive master digitization, and the assessment of the files purchased from external providers.

Active project

IP - based Systems and Technologies for Television Production

This programme deals with the experimentation of new IP technologies (networks, protocols, standards, equipment) in the area of television production, and particularly for studio applications.

Active project

Laboratory characterization of the antenna performance for a typical LTE-800 device

The characterisation of a typical LTE cellphone embedded antenna has been done, in order to enable the simulations of geographic coverage for a terrestrial television service towards mobile terminals.

Active project

Rai Remote Controller

The red button on Rai channels

The Rai Remote Control is an interactive application to DVB MHP standard: available on digital terrestrial platforms (DTT) and satellite (tivùsat), has the aim to aggregate in an easy-to-use graphical interface the Rai offer of TV channels, radio channels and interactive services for those televisions and decoders that can be connected to the internet.
