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:

Project coordinator Lyndon Nixon will speak at the Internet of Education conference, in Ljubljana, Slovenia this coming November 11, 2013. (see

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.

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 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 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.

MediaMixer is pleased to announce a Call for Multimedia Grand Challenge Solutions: Participate in the MediaMixer/VideoLectures.NET Temporal Segmentation and Annotation Grand Challenge, and win a trip to Ljubljana, Slovenia!

to be held at ACM Multimedia 2013, Barcelona, Spain, October 21-25, 2013

offical Grand Challenge page:


VideoLectures.NET mostly hosts lectures 1 to 1.5h long linked with slides and enriched with metadata and additional textual contents. With automatic temporal segmentation and annotation of the video we would gain on efficiency of our video search engine and be able to provide users with the ability to search for sections within a video, as well as recommend similar content. This would mean that the challenge participants develop tools for automatic segmentation of videos that could then be implemented in VideoLectures.NET.

The criteria for the evaluation of the proposed solutions to this challenge include the quality of the segmentation and the annotations, the duration of the required processing in time, and the ease of integration of the proposed solutions into VideoLectures.NET.

A dataset of Videos from VideoLectures.NET will be provided. Participants are also free to use additional datasets for testing their approaches, in addition to the videos provided by the Challenge organizers.

Submissions should depict working, presentable systems or demos, using the provided grand challenge dataset, and should describe why the system presents a novel and interesting solution.

The submissions (max 4 pages) should be formatted according to ACM Multimedia formatting guidelines. Multimedia Grand Challenge reviewing is Double-blind so authors shouldn’t reveal their identity in the paper. The finalists will be selected by a committee consisting of academia and industry representatives, based on novelty, presentation, scientific interest of the approach and performance against the task.

Finalist submissions will be published in the conference proceedings, and will be presented in a special event during the ACM Multimedia 2013 conference in Barcelona, Spain. At the conference, finalists will be requested to introduce their solutions, give a quick demo, and take questions from the judges and the audience. Winners will be selected for Multimedia Grand Challenge awards based on their presentation. An additional prize (sponsored by Technicolor) will be awarded to the most innovative multimodal solution, and a special MediaMixer prize will be awarded to the best solution presented for the MediaMixer/VideoLectures.NET Challenge.

Challenge Dataset: Already available!
Paper Submission Deadline: July 1, 2013
Notification of Acceptance: July 29, 2013
Camera-Ready Submission Deadline: August 12, 2013


MediaMixer is pleased to sponsor a prize for the Grand Challenge. The best solution – as determined by the evaluation criteria and subject to final decision by the challenge organizers – wins the submitting author(s) a trip to beautiful Ljubljana, Slovenia!

The winners are invited to visit the offices of VideoLecture.NET, meet the team over lunch and discuss how their solution may be integrated into the next release of the video portal. The rest of their stay they are free to explore Slovenia’s capital city.

The prize is reimbursement of flight and hotel costs for up to *2* persons (at least one of whom MUST be a named author of the winning paper) to Ljubljana, Slovenia. The flight taken must be in economy class and the hotel stay no more than 2 nights, and a maximum reimbursement amount of 1000€ can be claimed, subject to the provision of original receipts.

The first step is to contact us, we will answer any questions you have and most importantly we can give you access to the MediaMixer/VideoLectures.NET Challenge dataset.
