Over The Top
TV services, live or VOD, distributed over the Internet. Unlike IPTV services, where the telecom operator delivering the service is in charge of guaranteeing the transmission reliability, in case of OTT services the connection is established as “Best Effort”: the variability of the available network throughput on the net, caused by traffic peaks, can cause variations of the quality perceived by the user.

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.
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).
RaiPlay on connected TV
The blue key on Rai channels
RaiPlay, the new Rai multimedia portal released in 2016, is available as a browser and as an application for mobile devices and smart TVs. CRIT has overseen the software development of the TV version and interactive decoders to DVB MHP standard with gold stamp.
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.

Satellite supporting CDNs for the distribution of OTT services
The integration of terrestrial and satellite telecommunication networks will allow the widespread distribution of OTT contents, offloading the CDN backbone during traffic peaks, for the benefit of the effective picture quality perceived by the users.
