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.

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.
