CRIT at EBU Metadata Developer Network Workshop
Maurizio Montagnuolo presented the AgileRAI system, a parallel and scalable framework for real-time video analysis and semantic enrichment.
Teaching in the "Disability Technologies" course
A group of CRIT researchers presented Rai e-inclusion projects in the course of “Technologies for Disabilities“, in the Politecnico of Turin.
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.
Satellite transmissions beyond S2X
The DVB is currently starting a Commercial Study Mission casting DVB’s Vision for Satellite Broadcasting, looking at the near- and long term, and going beyond classic geostationary satellite constellations, anticipating a successful bringing into use of future low earth orbiting payloads.
Rai-CRIT will participate in these activities, according to its leaderschip role and active participation in the DVB technical module dedicated to satellite transmissions, aiming at evaluating opportunities, times and methods for new standardisation activities.
Application of the WiB concept to DVB-T2
WiB is a new system concept for DTT where potentially all frequencies within the Ultra High Frequency (UHF) band are used on all transmitter sites (i.e. reuse-1).
4K, the evolution of Television
The prospects for a new way of watching TV
Più pixel o pixel di miglior qualità? Le problematiche di un segnale a risoluzione maggiore contro un segnale a qualità migliorata. Le sfide della Rai e del Centro Ricerche verso una televisione ad alta qualità tecnica.
High Dynamic Range
The evolution of television signal: same definition, best pixels
The High Dynamic Range allows a significantly improved image. The pixels that compose the image are high quality compared to the current pixels, with more information content. The signal reproduced on the new HDR screens is more dynamic and therefore with a much higher brightness, as well as with a superior detail perception.
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.
Realtà Aumentata e Realtà Mixata
Una nuova tecnologia in grado, tra le altre cose, di coinvolgere maggiormente gli utenti delle trasmissioni televisiva.
Technology for "Data Journalism" activities
In the modern digital age, a big challenge lies in the ability of collecting, connecting, analysing and presenting heterogeneous content streams, accessible through different sources, and published through different media modalities. At this purpose, the project is aiming at identifying an end-to-end workflow for data driven journalism.
Multimedia IN Digital radio
MIND: a management system for Digital Radio Multimedia Services
MIND is the “Content Management” and “Multichannel Publishing” system that allows to associate and synchronize images and textual information with each of the DAB+ radio channels distributed across the network nationwide. Its ability to synchronize with the channel’s schedule and to choose and create new content to be transmitted, allows to get a channel dynamism even without a continuous publisher’s intervention.
Next Generation Audio
Una nuova generazione di tecnologie audio è in arrivo nel broadcasting.
E’ opportuno parlare di Next Generation Audio in quanto nel broadcasting si sta prefigurando uno scenario altamente innovativo, in cui, oltre al tradizionale aumento di efficienza di codifica tipico dell’evoluzione tecnologica, si aggiungono nuove ed importanti funzionalità che richiederanno ai produttori di contenuti un adattamento della proprio workflow di produzione.
RaiPlay on connected TV
The blue key on Rai channels
RaiPlay, il nuovo portale multimediale della Rai rilasciato nel 2016, è disponibile in versione browser e come applicazione per dispositivi mobili e smart TV. Il CRIT ha curato lo sviluppo software della versione per i televisori e decoder interattivi a standard DVB MHP con bollino gold.
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.
Digitisation of RAI Master archive
The RAI internal project for the digitisation of archive audiovisual material currently stored on physical legacy carriers. It aims at the preservation of RAI contents produced and communicated to the public till present day. The Centre for Research and Technological Innovation is involved together with other RAI departments, namely Teche, ICT, and Produzione-TV.
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.
