MediaMixer promotes technology for fragmenting media assets and making it possible to annotate those fragments for subsequent retrieval and re-mixing in new contexts. We believe this can help media owners to derive more value from their assets by making those assets more useful for media consumers.

Our last live Webinar addressed how to create fragments out of larger media assets such as videos.  Vasileios Mezaris of Greek research centre CERTH discusses a set of video processing techniques for media fragment creation and annotation. These include techniques for the temporal segmentation of the video into shots and scenes, the re-detection of appearances of specific objects throughout the video, and the detection of concepts that describe the temporal video fragments. Such techniques are the first step towards converting the raw video material into meaningful media fragments.


MediaMixer partner JSI will present the project demos on e-learning, news and media rights management this week during a fully booked workshop at Online Educa (Berlin, 4-6 December).

The Wednesday afternoon workshop “Artificial Intelligence Methods for Online-Based Education” has as its aims:

  • To present state-of-the-art machine translation methods and tools
  • To present state-of-the-art user profiling, aggregation and methods and tools
  • To present state-of-the-art cross lingual knowledge technologies
  • To present success stories from similar domains
  • To discuss future directions and potential projects

The participants as an outcome of the workshop will be able to understand how new technologies offer universities and academic communities new solutions to old and familiar problems. Higher education is trying to catch up with the changes of the digital age and the internet, and so the main goal of this half-day event is to clarify how emerging technologies, based on machine learning, machine translation, text mining, semantic web, open access, academic video journals, free video libraries, open lecture capture systems, OER and more, can change and help co-create emerging publishing, curriculum, designation, filtration, validation and research trends in Academia in Europe and in general.

For non-attendees, the demo videos can be seen at http://community.mediamixer.eu/demonstrators

Tomorrow, 22 November 2013, Martin Dow of project partner ACUITY Unlimited will speak at Archiving Tomorrow 2013 on “MediaMixer technologies: semantic multimedia and media archives”.

Archiving Tomorrow (AT-13) is a new international conference covering aspects of media archiving and restoration. Chaired and supported by leading figures in the film, media and broadcast communities, Archiving Tomorrow will become the premier annual event for archivists, film makers, creatives, academics, manufacturers and those wishing to find out about this exciting area.

MediaMixer is pleased to be involved and to present how the technology it promotes – semantic annotations applied to media fragments – can be used in media archives to improve media search and retrieval at fragment level. We believe the application of MediaMixer technology can contribute to archive materials’ re-use, re-mixing and even re-selling, respecting digital rights and owners’ copyright.

MediaMixer co-ordinator Lyndon Nixon presented at the Internet of Education 2013 conference at Ljubljana, Slovenia (organised by project partner Jozef Stefan Institute) one possible MediaMixer future of e-learning. In this future, learning videos are mashed up to generate new learning offers for online learners, and such re-mixes could be the basis for new MOOC offers that are more flexible and personalised to individual learners. Dr Nixon noted that as e-learning materials become increasingly video, there are new requirements on how to retrieve relevant video by topic and access it in term of its parts (fragments), especially relevant for learners on the go or on mobile devices.

MediaMixer technology is a solution for this, as shown by our use case with VideoLectures.NET, the VideoLecturesMashup. This use case has been described previously, and the video of the demonstrator is also online.

Our slides on MediaMixing for e-learning are available:

Our colleague Vasileios Mezaris (CERTH) will hold the next live Webinar on 14 November (1100 CET) at http://www.mediamixer.eu/live.  It is titled “Fragmenting your Media Assets meaningfully – media analysis for fragment detection and extraction“.

The Webinar will discuss a set of video processing techniques for media fragment creation and annotation. These include techniques for the temporal segmentation of the video into shots and scenes, the re-detection of appearances of specific objects throughout the video, and the detection of concepts that describe the temporal video fragments. Such techniques are the first step towards converting the raw video material into meaningful media fragments.

Join the live presentation and discuss with us via Twitter @project_mmixer. Webinars are also recorded and will be available online at http://mediamixer.eu/live later. MediaMixer community members receive regular mails reminding them of MediaMixer activities – join free at http://community.mediamixer.eu 

Project coordinator Lyndon Nixon will speak at the Internet of Education conference, in Ljubljana, Slovenia this coming November 11, 2013. (see http://www.k4all.org/Internet_of_Education/)

The already booked out event will bring together researchers and policy makers from both university and academia to research into methods for improving the effectiveness of video based MOOC education.

Dr Nixon will highlight the MediaMixer offer of semantic media and media fragments, concretely demonstrating its benefits in an extension of the VideoLectures.NET platform in which learning videos can be explored by topic, across collections, in the form of sequences of different video fragments which are annotated with the same terms.

The MediaMixer project is pleased to release a demo of semantic technologies facilitating copyright management in the context of User Generated Content.

It is a key issue for the media industry these days, in addition to unauthorised media reproduction and distribution, to control the reuse of media in user generated content (UGC). To solve this issue and avoid publishing content that infringes copyright, UGC services like YouTube offer mechanism to detect the unauthorised reuse of media, and give the choice to monetarise its use rather than take down the content. However, all the potential of this new revenue stream is at risk if copyright subtleties are not managed appropriately. For instance, if the same song is owned by different rights holders depending on the territory.

What is required is a scalable decision support system capable of integrating digital rights languages, like DDEX or ODRL, together with contracts or policies, like talent contracts or business policies.
MediaMixer semantic technologies provide a common and expressive framework where all these copyright information sources can be represented together.

The daily news shows have become the TV broadcaster´s first reference to their viewers. But unfortunately, the delivery of just-in-time, high quality news shows has become more challenging over the last years, by the needs 1) to serve the cross-department workflow integrating the growing number of input channels, 2) for a more complex composition of news contents to serve additional distribution channels and 3) to further exploit the available vast archives and raw materials.

Regarding this challenges, the MediaMixer project offers to shift the workflow more towards the Media Fragment level and employ the MediaMixer toolset in a SmartNews use case. This allows to improve the news production through:

  • the cross-department retrieval for specific persons, places or objects inside the vast video content,
  • the establishment of a repository with re-usable video snippets improving the collaboration and shorten production time and
  • the more flexible composition of contents to serve different distribution channels such as Internet, TV, HbbTV or mobile TV. In addition, the semi-automatic Media Fragment identification and annotation of the MediaMixer toolset enables to better exploit the vast amount of footage and raw materials.

The MediaMixer project provides a demonstrator offering retrieval, recommendation and re-use of Media Fragments for newsroom editors in the “Climate” and “Renewable Energy” domains. 


News video material storage and retrieval for the broadcasters’ newsroom is promoted by the partner CONDAT providing search and recommendation support for the newsroom tool of ANNOVA1 GmbH for MediaMixer.

1 ANNOVA is one of the leading TV newsroom providers in Europe

The MediaMixer project is pleased to announce the release of the recording of our recent Webinar on Describing Media Assets, given by Raphael Troncy of EURECOM. In this talk he explains how semantic descriptions of non-textual media available on the Web can facilitate retrieval, re-use and presentation of media assets.

He first presents the Media Fragment URI specification, a recent W3C recommendation that enables to uniquely identifying sub-parts of media assets in the same way that the fragment identifier in the URI can refer to part of an HTML or XML document. Then models and ontologies are described that we will illustrate with several real world applications using semantic annotations attached to media fragments.

This is the second in a set of Webinars on MediaMixer technology and their benefits for the enterprise, see http://mediamixer.eu/live for the full schedule and past Webinar recordings.

MediaMixer Webinars are made possible thanks to the Jozef Stefan Institute and VideoLectures.NET.
