Computerization of Production
Vertical and horizontal
We need to move from a television production model based on vertical supply chains to a horizontal integration. From an organizational and technological structure based on separate joints and specialized on a particular distribution channel, to an integrated model capable of producing and distributing content on heterogeneous channels.
Because this transition is fulfilled it is necessary for the production infrastructures evolve towards a progressive computerization of the audiovisual signal processing chain. Content management should be based on the exchange of files across computer networks, agnostic than video parameters of the transported content. To ensure interoperability between systems and to minimize the overhead imposed by the format change has, however, need to carefully govern the selection and evolution of the formats supported, with particular attention to audio coding systems and video and the format of encapsulation in files.
New systems for the computerized management of the video
Manufacturers have already perceived the need for technology change.
In fact, the major players in the industry offering registration systems based on computer type media (solid state memory, Blu-ray, hard disk) that, in addition to being used in traditional video mode, allow you to interface with computer systems and to download content directly in the form of files.
The computerized management of the video also favors the simultaneous insertion of metadata for the description of the content and processes. Now is the real key to improving the efficiency of processing flows and to leverage on the signal format flexibility that characterizes information technology, facilitating content reuse and automation of processes.
Experiments and achievements
The activities of the Research Centre in this scenario is aimed at testing the most promising technologies and architectures.
Set up a video server captures standard definition and HD signals and save them as files according to various user-defined encoding profiles. The same apparatus can also be used to make the playback of files according to a variety of common formats.
They made for compatibility between the files in MXF (Material Exchange Format) products from major manufacturers and they implementative the gaps were highlighted, which led to the establishment of a study group in the field EBU: P / HIPS (Harmonisation and Interoperability of HDTV Production Standards).
Also as part EBU has contributed to the definition of various standards in the management of metadata, and there is activity on the study of innovative architectures for the integration of complex systems based on SOA (Service Oriented Architecture), organized as joint Task Force, EBU and AMWA, led by the research Centre.

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.
European project PrestoPRIME
Keeping Audiovisual Content Alive
The European PrestoPRIME project aims to study and develop solutions that contribute to the creation of a framework for long-term preservation of digital audiovisual products.
Hyper Media News
System for automatic content analysis
Hyper Media News is a system able to integrate the information automatically generated by ANTS with the information on the web and made available through the daily online information sites.
The Hyper Media News system, together with ANTS, has already been successfully demonstrated on several occasions during international scientific conferences and during the Prix Italia 2009.
Automatic Newscast Transcription System
It was built a platform, called ANTS, targeted analysis auto news. It is a modular system in which several of the audiovisual signal analysis tools are coordinated by a process management engine, which has the task of making sequential stages of the preparation, and to aggregate the resulting data.
Archives and digital Thecae
A huge archive and information technology to turn it into a working tool, in a handy storage, in a familiar territory and just a click away. It ‘a complex enterprise that aims to computerize the Teche Rai, with problematic issues on which you are measuring a multi-year business plan.
