Digital media systems


Our technological solutions give our customers the freedom to choose their next, and future suppliers.

VTT uses its modelling know-how and process and technology surveys to develop standard-based solutions for digital media production. This enables versatile, flexible and continuous development of easily transferable systems.

As an example, we determined the transfer of metadata for the HelMet e-library in the ebook value chain, and designed the functionalities of the digital library. Our work for the HelMet e-library resulted in an internationally competitive solution that can be applied to other digital libraries.

We also licensed a method for the HelMet e-library's adaptive recommendation system. This system recommends new books to library users on the basis of the library customers' borrowing history.

Processes are based on ePub, Onix3 and Xml metadata standards

VTT specialists draw on 15 years of experience in digital publication production processes and digital media production planning for various types of terminal devices, including smart phones and tablets.

Our strength lies in html5-based network technologies that allow us to create products for ordinary web browsers, such as adaptive, rich media user interfaces. This means that services can adapt to the user's terminal device characteristics, context, place and profile, among others.

We have examined the description, presentation and archiving of news material. Our aim was to define how an online service could provide user-specific news items through the right terminal device, and with perfect timing. Our solutions are used in various services created by enterprises.

Processing big data into media services of the future

Thanks to VTT's versatile research infrastructure, we are able to process big data into an easily understandable format, as well as turn processed data into completely new types of media services.

We are in active cooperation with businesses and research organisations through various projects and programmes, such as the Next Media programme with the University of Tampere and Aalto University. VTT played an important role in this programme, both in recognising the user needs and in prototype development.

Our typical customers include large media companies seeking to grow their revenues from digital content and services. However, we can also utilise the user data of online services to develop new types of solutions. This could be beneficial to online service producers in the fields of health and well-being.

​Applying JDF in the integration of the systems of a printing house

JDF (Job Definition Format) is an XML-based printing industry vocabulary which is needed in integrating different systems. JDF recommendation includes JMF (Job Messaging Format), which is used in sending messages from a system to another. With JDF and JMF the information can be transferred between different systems. Applying JDF, whether in pilot or in production, requires matching between the systems, even if the suppliers claimed their systems are JDF-compatible.

VTT has piloted JDF-based data transmission internally in printing house and between print shop and a customer in many projects. Practical experiences of JDF-based system integration have been gathered and cost-benefit analyses in different application areas have been made. Projects have included determining the data transmission needs between different systems and how JDF specification and related ICS-documents can match with these data transmission needs. When needed, JDF messages have been complemented with extensions required by the application area.

Book processes were mapped and a Finnish definition for book structure was defined in BookXML-projects. Based on these, a demonstration and later a pilot system applying the JDF specification for request for quote and quote between a book publisher and a print house was set up. JDF messages were complemented  by a BookXML-extension which conforms to the demands of the Finnish book business process. In addition, a model based on PrintTalk and JDF was created for business processes between book publishers and printers including links to the material transfer and editorial process.

JDF-pilot projects have included the definition of required data transmission and corresponding JDF messages between a magazine publisher and MIS of a print shop, and further between printers MIS and production systems (prepress, press, postpress) in sheetfed and web offset production. A uniform Finnish JDF-terminology was created for Finnish implementations. Practical  experiences including both setting up and use of a JDF-based workflow in print shops were gathered in pilots. Also, cost-benefit analyses on JDF-integration have been made.
