About lyndon.nixon@sti2.org

MediaMixer has published two new tutorials on its community portal, free to access by registered members:

They cover techniques and technologies to analyse media assets in order to determine the significant spatial and temporal regions which can be defined as separate media fragments. Each fragment can then be individually annotated with the concepts and topics they represent, using structured annotation models and ontologies to allow for semantic search and machine-automated processing.

The combination of these technologies can allow media owners to better prepare their media for retrieval and re-use, both internally and if desired by external parties who may have to agree to a specified license and/or pay a fee. Future tutorials by MediaMixer will address the topics of media fragment management, rights and re-use!


MediaMixer as a project is promoting the use of innovative semantic technology for analysing, annotating, managing and re-using media assets at the fragment level to the benefit of both the media owner and the media consumer.

However, any new technology needs explanation: what technology exists for each task? where is it and how can I use it? what does it support, what not, and what experiences have been had with it? MediaMixer supports interested adopters on its community portal with lists of useful software and demonstrators, and can directly help community members via online forums, events and offers of knowledge and technology transfer*.

As part of this, we just published the first version of the Core Technology Set.  This document introduces the different aspects of MediaMixer technology with a state of the art, existing technology and specifications, and links to further information and downloads. We cover:

  • Media Fragment specification, server playout and client playout
  • Media Fragment creation via visual analysis
  • Media Fragment description using annotation models and controlled vocabularies
  • Media Fragment rights management
  • Media Fragment asset management including fragment identification
  • Media Fragment re-use via search and retrieval in IT systems

This technology is in flux and we will update the Core Technology Set when necessary. Any registered community member (registration is free) can access the document, and if you have questions or comments on it, you can start a discussion in our What is MediaMixer? forum.

 


MediaMixer will be presented at the Metadata Developer Network Workshop 2013 (http://tech.ebu.ch/MDN2013), organised by the European Broadcasters Union. June 5-6 2013, Geneva, Switzerland. The talk “MediaMixer: facilitating media fragments mixing and its rights management using semantic technologies” to be given by Roberto García of the University of Lleida will focus on how Media Fragments will be also linked to rights information based on a copyright ontology, which integrates licenses, policies and rights expressions based on existing standards like DDEX, ODRL or MPEG-21.


MediaMixer has co-supported the first worldwide workshop on Linked Media (LiME) together with the EU project LinkedTV at the World Wide Web Conference (WWW2013). The workshop has promoted for the first time to the international Web community the vision and goals of “Linked Media”. MediaMixer promotes technology for eased publication and re-use of fragments of audiovisual media across the Web, which can be part of the Linked Media vision. Project co-ordinator Lyndon Nixon held a keynote talk at the workshop outlining his goals for making Linked Media a reality – the keynote slides can be seen at http://de.slideshare.net/linkedtv/www-linked-media-keynote


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:
http://acmmm13.org/submissions/call-for-multimedia-grand-challenge-solutions/mediamixervideolectures-net-grand-challenge/

CHALLENGE DESCRIPTION
———————

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 AND PUBLICATION OF RESULTS
————————————–
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.

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

SUBMIT AND WIN A TRIP TO LJUBLJANA
———————————-

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.

MediaMixer partner JSI is pleased to announce a special workshop on “Advanced Methods and Tools for Web-based Education” one day before the main OCWC Global Conference 2013. OCWC – the Open CourseWare Consortium – is a collaboration of more than 200 higher education institutions and associated organizations from around the world creating a broad and deep body of open educational content using a shared model. The mission of the OpenCourseWare Consortium is to advance education and empower people worldwide. The workshop will permit conference attendees to learn about, among others, technologies for granular level media fragment re-purposing and re-mixing that may be pertinent to setting up an e-learning or open education project.

 


VideoLectures.Net and the MediaMixer project have launched a challenge at the 21st ACM International Conference on Multimedia. This requires participants to develop tools for automatic segmentation of videos that could then be implemented in the video library. For more information and submission guidelines visit the official website. The finalists will be published in the proceedings and presented in a special event during the conference in Barcelona.

Call for participation now published

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.

Evaluation

There will be 3 criteria for evaluation:

1. The quality of segmentation and annotation. The key criteria for evaluation will be the quality of the segmentations and annotations* that are extracted from a particular video. Goal: most clearly separated and detailed automatic description of why a segment is a new segment. For the annotations of the segments we do not have a specified vocabulary. Participants should annotate the segments with descriptive labels that allow us to differentiate between various segments and retrieve subsets of them, e.g. using labels of actions (presentation, Q&A, etc.) or also labels based on presentation (sub-)topics.

2. Service effectiveness. How to increase the searchability of the content (when searching for specific content using a search engine, or while browsing)? Goal: quality of annotations used for searching; duration of the processing in time; amount of processed data.

3. Efficiency of the underlying algorithm. Goal: ease of integration, processing speed.

Dataset

Videos 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.
