The paper “Semantic Copyright Management of Media Fragments” will be presented at the DATA 2013 conference next July 30th. The paper, authored by Roberto García, David Castellà and Rosa Gil from MediaMixer partner Universitat de Lleida, describes the proposal of the European project MediaMixer for media reuse. Media fragments and the management of their rights, beyond simple access control, are the centrepieces of this proposal. The paper focuses on the latter, for which it is necessary to provide highly expressive rights representations that can be connected to media fragments. Ontologies provide enough expressive power and facilitate the implementation of copyright management solutions that can scale in such a scenario. The proposed Copyright Ontology is based on Semantic Web technologies, which facilitate implementations at the Web scale, can reuse existing recommendations for media fragments identifiers and interoperate with existing standards. To illustrate these benefits, the papers presents a use case where the ontology is used to enable copyright reasoning on top of DDEX data, the industry standard for information exchange along media value chains.

The W3C recommendation on the Media Fragment URI specification is an important part of the technological solution promoted by MediaMixer. It provides a standardised manner to refer to spatial and temporal fragments of a media item with the goal that this can be used across software systems in a media workflow. Now MediaMixer has published links on its community portal to two background presentations on Media Fragments:
- “Addressing and annotating Media Fragments” is an introductory tutorial to the media fragment specification
- “Implementing the Media Fragments URI specification” adds more technical detail especially in terms of media server implementation supporting media fragments
Material on Media Fragments will also be updated after the summer and the subject of a dedicated Webinar by MediaMixer, stay tuned!
FOCAL, the Federation of Commercial Audiovisual Libraries, will hold a conference on “Metadata and why it is important” next week, July 10, in London. The conference – which can still be registered for – will examine the value of metadata in the media workflow and the importance of considering metadata from the very beginning. “What you shoot today is in the archive tomorrow”.
In the New Developments session before lunch, MediaMixer partner Martin Dow of Acuity Unlimited will briefly outline how the cutting edge media technology promoted by MediaMixer can serve to improve the creation of media metadata in the capture stage as well as subsequently its value for media storage, retrieval and re-use:
- Media fragment URIs can make individual media assets more valuable and flexibly re-usable by allowing different software systems to refer to specific spatial and temporal parts in an agreed manner;
- Media analysis technology can help companies automatically identify the relevant spatial and temporal fragments and classify the objects and events perceived in those fragments (see our demo);
- Semantic media annotation provides a rich association of high level concepts (persons, places, objects, events) to media fragments and the use of additional Web knowledge (ontologies) to answer complex, conceptual queries with relevant media fragments (e.g. “shots of US Presidents meeting with African leaders”).
MediaMixer is interested in a discussion about how media asset management and digital rights management approaches need to be expanded to take into account the support for media fragments and the association of fragments with rich, semantic annotations, if the above technologies are to be integrated into enterprise media workflows. Meet Martin at the FOCAL Metadata event, and join our community where you can also enter into a discussion with us.
One of the challenges faced by the MediaMixer consortium is that there is no pre-existing industry “buzzword” or well-defined market segment for “semantic multimedia”, or combining “the web” (the application of fragment URIs and linked data in particular) across the broadcast and media value chain. MediaMixer’s community represents part of the solution, by providing a focal point where these techniques may be brought together, drawing together common strands from more established segments.
IBC is the foremost media conference for the broadcast-related industry. The “Booster” was the first event of its type for IBC, promoting interactive formats designed to address the need for delegates from all areas of the media value chain associated with broadcast, to better share insights and information regarding their innovations and future predictions. MediaMixer is predicated on the assumption that semantic multimedia and specific W3C web standards being important in the future, so it was beneficial to the project and industry attendees that MediaMixer was visible at the event. Most presentations required audience participation. The two themes, “Cloud” and “Connecting Content”, are both umbrella themes that broadly encompass the touch points the industry has with MediaMixer’s topics.
MediaMixer is pleased to have been Silver Sponsor at this event and our colleague Martin Dow had the pleasure to engage with attendees on the MediaMixer offer and benefits of community membership. Martin will speak again about MediaMixer at a FOCAL Metadata conference in London on July 10, 2013.
The recent Metadata Developer Network Workshop organised by the EBU in Geneva on 5-6 June 2013 included a talk by Roberto García González of the University of Lleida. The subject was “facilitating media fragment mixing and its rights management using semantic technology” (slides online)
Our finding from the event was that broadcasters are progressively maturing towards applying semantic technology, perceiving opportunities there but taking slow steps to avoid internal technological disruptions, where many are now at the stage of working with structured data in the form of XML, mappings with XSLT etc.
MediaMixer will continue to work to encourage gradual adoption of the new technology through providing informative materials, highlighting use cases and preparing proof of concept demonstrators.
In the context of the MediaMixer use case on mashing up e-learning video, the technical partner CERTH and the use case partner JSI (for VideoLectures.net) have produced an online demonstration of technology necessary for the first step: creating fragments of the learning video assets and detecting concepts of relevance in those fragments.
Check the demonstrator at http://160.40.50.201/mediamixer/demonstrator.html and give us your feedback and comments on the technology at our forum on fragment creation and description.
*Due to the VideoLectures.NET dataset (lectures) the demo does not express the full potential of the video shot segmentation and concept detection process, but is still a nice example.
Do you have datasets which could be more suitable for creating media fragments with video analysis techniques? Become our community member and get to know MediaMixer technologies!
Our partner Josef Stefan Institute has uploaded a technical update on its use case with the e-learning video platform VideoLectures.net. Now the technical work will start to create a working demonstrator of VideoLecturesMashup – media fragment playout for learning about topics shared across different learning video materials! See http://community.mediamixer.eu/usecases/ucvideolectures for the slides.
This has been complemented by a presentation on “advanced methods and tools for Web-based education” covering various project approaches including MediaMixer, see http://de.slideshare.net/MediaMixerCommunity/intelligent-toolsmitjajermol2013bali7-may2013-22424692.

- TELL ME WHY! AIN’T NOTHIN’ BUT A MISTAKE? DESCRIBING MEDIA ITEM DIFFERENCES WITH MEDIA FRAGMENTS URI AND SPEECH SYNTHESIS
- A FEATURE-ANALYSIS BASED FRAGMENT REMIX INSTRUMENT
MediaMixer, who will be represented at ICME 2013 by our colleague Vasileios Mezaris (of the Greek research centre CERTH), looks forward to seeing ICME attendees at our workshop!
This month, June 2013, MediaMixer partner Acuity Unlimited will be present at two media events, the Sheffield Doc/Fest on June 12 and the IBC London Technology Booster on June 25-26. Meet our representative Martin Dow to learn more about MediaMixer’s offer to community members:
- the Crossover Interactive Summit focuses on Transformers, people who want to change the world and have moved from one platform to another to do so: filmmakers creating apps, doc producers moving to social platforms, app designers making hardware and video game developers making physical objects. Acuity can explain web standards-oriented media technologies to enable diverse possibilities for media access and reuse across multi-platform production contexts.
- IBC’s inaugural London based conference will cover today’s two hottest technology topics – Connected Content and The Cloud. Such “new technologies for connecting content to consumers” include what MediaMixer promotes, and Acuity can explain MediaMixer’s semantic and web standards-oriented approach to fine-grained Connected Content, and the significant role played by linked data on the web to media management, rights management and metadata enrichment in the Cloud.
With the title “Advanced Methods and Tools for Web-based Education”, this event at the OCWC Global conference brought together students, researchers and other professionals from diverse technological, social and educational backgrounds to understand the ways in which new technologies are shaping the future of education. Organised by FP7 projects such as transLectures, Xlike and Mediamixer, this one-day event was held immediately prior to the main conference in Bali, Indonesia and was by all means very successful.
The lecture room was completely full hosting 27 attendees from 1) APTIKOM, an association of colleges and universities in Indonesia that offer educational programs in computing, information systems and technology – out of 2,750 higher education institutions in the country, approximately 750 of them are the members of APTIKOM, with a collective student body of 600,000 people – 2) the OpenCourseWare Consortium, 3) the Ministry of Communication and Informatics of Indonesia, and 4) the Ministry of Education and Culture of Indonesia. The speakers were Marko Grobelnik (JSI), Mitja Jermol (JSI) and Colin de la Higuera (Uni. Nantes).
Since the workshop was directed towards showing the participants an overview of the European state-of-the-art on new-media solutions, the workshop presented 1) short introduction to machine learning, machine translation language technologies, 2) an introduction to advanced large scale data analytics (big data), 3) language-agnostic cross-lingual services, and 4) technologies to monitor and aggregate knowledge that is currently spread across different domain collections, and granular level media fragment re-purposing and re-mixing that may be pertinent to setting up an e-learning or open education project.
Mediamixer fits into this workshop scenario by providing a community that can help these practitioners that are opening up to online educational videos, thereby expanding the consumer base of any given video for sharing and re-purposing. One of the main facilitator being the exponential growth of Internet access in Indonesia with 25% penetration and 80 million users – all high consumers of digital online content,mostly via smart devices. This uptake is also present and visible in the audio-visual market.
The videos, presentations and follow up news to the workshop will be posted on the Knowledge 4 All Foundation Ltd. website (http://www.k4all.org/?q=node/1093) for further consumption.
