DVB-I

The TV programme list is enriched with new channels received via the Internet

The future DVB-I standard aims to deliver TV programmes over the Internet, so that they can be received and displayed by a variety of connected receivers (TVs, PCs, tablets, smartphones) with the same ease of use as today’s traditional TV programmes received from an antenna.

The new DVB-I services will be discovered by means of an installation procedure functionally equivalent to a frequency scan, and included in a channel list having a Logical Channel Numbering (LCN) harmonised with broadcast services.

DAB+: the digital evolution of radio

In Italy, radio is one of the most popular media, thanks to its immediacy and ubiquity. DAB+ is the technology chosen by most European countries for the digital evolution of radio. Reliability, sound quality, transmission efficiency, energy efficiency, textual and graphic information services: DAB+ Digital Radio overcomes analogue radio in several ways.

The standard has been successfully adopted by several European countries: as Norway, Germany, United Kingdom, Switzerland, Netherlands, Denmark, Italy. Among them, Norway has begun the FM switch-off at the beginning of 2017, and other countries have plans for the Digital Switch-Over.

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).

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.

DAB+ signal propagation in tunnels

tests and measurements

Rai is planning to extend DAB+ services to the most important Italian urban areas and to the motorways (including service continuity in tunnels). Radio service transmission inside tunnels requires methods such as the installation of radiating cables (“leaky-feeders”) along the tunnel ceiling. This approach is costly, thus leading RAI Research Center to investigate the feasibility of an alternative approach using direct RF irradiation by means of antennas positioned outside the tunnels (not far from the entrance) or internally.

Stretched TV for improved accessibility

TV adapted to its time

The film and television have undergone an extraordinary evolution in the technical means as in content. The need to keep up with the times and with a society living in ever-increasing pace has profoundly changed the way of realizing television and radio programs. The manner of conducting the programs has changed dramatically from the fifties to the present, from a television in black and white that “entered” into the homes with discretion and played just a few hours of the day of a program like the present with channels broadcasting 24 hours daily and characterized by fast tempos and rhythms. the user is also changed, now the viewer quickly select with the remote control a number of channels to decide what to watch and with TVs connected to the network selects the contents and realizes its own schedule. People with disabilities and the elderly, by contrast, strongly demanding the reduction of the complexity of television and the reduction of technological barriers. The project Stretch TV, launched by RAI – Centre for Research and Technological Innovation and RAI – Social Secretariat, aims to develop a technological solution that allows to significantly improve the usability of television content by persons with sensory disabilities and / or cognitive and the elderly.

TV over the Internet: OTT (Over The Top) distribution of audio/video content

Today, TV content can be distributed via Internet as OTT (Over The Top) delivery, allowing to expand the traditional offer with on-demand services. As the QoS (Quality of Service) cannot be guaranteed on the Internet as on a private IP network, during the years specific network architectures have been designed and developed (CDN: Content Distribution Network) and adaptive streaming protocols (ABR: Adaptive Bit-Rate), in order to optimise the data stream according to the broadband connection and the kind o terminal associated to each user.
