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.
social networks analysis in the television environment
The huge transformation on how we enjoy television content is by now a fact, it is increasingly emerging that the second screens (PCs, tablets, smartphones) have become a structural extension of television media, so that content producers are called to address the challenge of providing real-world entertainment and information experiences that can be viewed through different device and media in synergy.
From these considerations there are new opportunities for the entire television production sector. Social media, in particular, can increase the knowledge of user’s perception of the program and at the same time maximize the audience using multiple screens. The picture that we are looking requires to offer no more simple television products such as linear audio / video but true experiential paths, a profound transformation of the television offer not only multi-device but trimmed to the needs of the user, able to capture user in the most diverse situations. This requires an in-depth knowledge of consumer behavior.
In this context it becomes essential to identify the synergies between the television world and the WEB, with particular attention to social networks and what level of integration and collaboration can be achieved between the two worlds.
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).
