MediaMixer will give its next LIVE Webinar – online at http://mediamixer.eu/live – on February 3rd at 1130 CET on the topic of Semantic Management of your Media Fragments Rights

This webinar continues with the MediaMixer semantics-based media workflow. Once media has been fragmented and fragments semantically annotated, it is time to manage them. Digital Asset Management (DAM) solutions empowered by semantic technologies help managing assets lifecycle at the fragment level. This includes copyright management to facilitate their reuse and exploitation. MediaMixer proposes the use of a copyright ontology based on semantic technologies, which models access control policies and offers the possibility of automating licence checks and filtering of available content against their terms of use. In this case, semantic technologies make it possible to go beyond Digital Rights Management and, because it is possible to model copyright through the whole media value chain, manage media rights from creation or remix to end-user consumption.

Join us on February 3rd, 1130 CET, live with Q&A via Twitter and TitanPad at http://mediamixer.eu/live

A MediaMixer submission together with the team at VideoLectures.NET entitied “Video Lectures Mashup – remixing learning materials for topic-centred learning across collections” will be presented in April 23-25 at the OCW Global Conference 2014, in Ljubljana, Slovenia.

The OCW Consortium global conference is the annual opportunity for researchers, practitioners, policy makers and educators to deeply explore open education and its impact on global education.  Conference participants will hear from global thought leaders in open education and have the opportunity to share ideas, practices and discuss issues important to the future of education worldwide.  Sessions cover new developments in open education, research results, innovative technology, policy implementation, best practices and practical solutions to challenges facing education around the world.

MediaMixer’s presentation will look at using media fragment and semantic media technology to help make it easier for learners to browse topics across video lectures from different collections, and show our prototype with VideoLectures.NET content.

MediaMixer partner CERTH has released a video showing a demo of video shot segmentation and visual concept detection applied to lecture videos. All the processing of the videos was performed using automatic analysis techniques. Results can be used to support the subsequent annotation and re-use of the video materials, as in the VideoLecturesMashup use case.

Happy New Year from project MediaMixer! Next week is also the next Webinar, on January 14th (2pm CET) our use case partners will present their use of MediaMixer technology: a Semantic Newsroom enables the news editor to access on demand relevant video snippets around the in-focus news story, while VideoLecturesMashup is capable of accepting a specific learning topic as input and produces as a result a mashup of fragments of learning materials from the site addressing that topic, ordered in a meaningful way. The talk will reflect on the new learning opportunities realised for online learners as a result of the MediaMixer technology. All Webinars are broadcast live at http://mediamixer.eu/live and available afterwards courtesy of VideoLectures.NET (http://videolectures.net/mediamixer_webinars/)

Topic and description of the tutorial

This tutorial will address the state of the art in the area of online media analysis, annotation and
linking, reflecting that a number of Web-based specifications and technologies are now emerging
that in combination can provide the technical solution for media owners to be enabled to manage
and re-use their online media at a fragment level.

Alone the need to raise the visibility of these individual Web-based specifications and technologies,
part of the remit of the MediaMixer project which will support this tutorial, would motivate the
tutorial for researchers and practitioners in the multimedia domain: the W3C Media Fragment
specification offers a chance to have a standard URL-based expression for media fragments across
the Web, the W3C Media Ontology and Open Annotation Models with their fragment re-use
specific extensions in projects like LinkedTV offer the possibility of interchangable and machine
reusable semantic media descriptions across repositories, , support for media fragments and the
related specifications needs to be built into multimedia search and retrieval systems and HTML5-
based media playout technology with the first early adopters being visible. On top of this, the
combination of these specifications and technologies can form a full online media workflow able to
support media fragmentation and re-use, which opens means to derive new value from media to
media owners and new models for media acquisition and use for media consumers. Hence the
awareness of and ability to use these specifications and technologies will be of great importance to
future curators and publishers of online media.

Intended audience

The target audience is researchers from the different areas of Web multimedia research that deal
with the analysis, organization and indexing of online multimedia content, with an interest of being
enabled to better do so at fragment level, as well as developers of novel applications for the re-use
and re-mixing of media fragments which can be of benefit to media owners, providers and
consumers. The participants of the tutorial will gain an insight into the current state-of-the-art of
research on multimedia fragments and remixing. The participants will also have the opportunity to
hands-on use different tools for the purpose and create their own media re-mix.


Our tutorial is focused on intermediate skilled Web media researchers and professionals. It will
assume a basic knowledge in the principles around media analysis, annotation, management, search
and presentation but not assume the use of any specific technologies or standards.

Duration and program

We plan a half day tutorial of three one hour blocks plus breaks.

Session 1: Media fragment analysis and creation
Speaker: Vasileios Mezaris (CERTH)
Summary: Explain approaches to visual, audio and textual media analysis to automatically
generate meaningful media fragments out of a media resource. Demonstrate latest results in the
areas of video fragmentation, visual conceopt and event detection, face detection, object redetection,
and the use of speech recognition and keyword extraction from text for supporting
multimedia analysis.
Session 2: Media fragment specification and semantics
Speaker: Benoit Huet (EURECOM)
Summary: Introduce the W3C Media Fragment URI specification. Highlight how media fragments
can be incorporated into known media description schema, with a focus on the W3C Media
Ontology and the Open Annotation Model. Extensions to these ontologies to more richly link
media fragments to the concepts they represent.
Session 3: Media fragment re-mixing and playout
Speaker: Lyndon Nixon (MODUL)
Summary: A number of novel application ideas will be introduced based on the media fragment
creation, specification and rights management technologies. Semantic search and retrieval allows
us to organize sets of fragments by topical or conceptual relevance. These fragment sets can then
be played out in a non-linear fashion to create a new media re-mix. We look at a server-client
implementation supporting Media Fragments, before allowing the participants to take the sets of
media they have selected and create their own re-mix.

We are happy to announce the 1st International Workshop on Social Events in Web Multimedia, taking place in conjunction with ICMR 2014 (Glasgow, Scotland).

The modeling, detection and processing of events in video is an area that has started to receive considerable attention by the multimedia community, and is supported by both the LinkedTV and MediaMixer projects, who promote the value of richer annotation of web multimedia to industry communities such as broadcasters, media archives and producers.

This Workshop aims to attract and present the latest developments and results on the discovery of social events from web multimedia content, and on techniques for the detection and retrieval of media items that are related to such social events. By social events, we refer to events that are planned by people, are attended by people, and are represented by multimedia and in general social media content that is captured by people.

The target audience of this workshop includes all researchers and practitioners interested in the better understanding of multimedia retrieval and of events in the context of the Web and/or social networks. Submission of papers deadline is February 1st 2014, for more see the Call for Papers.

The EBU Semantic Web Activity Report provides an introduction to Semantic Web technologies for the EBU members and illustrates them through several use cases in the broadcast environment. As the report itself states:

The purpose of this report is to raise awareness on the importance and high potential of Semantic Web technologies now rapidly developing from initial conceptual prototypes to services in real production also in the broadcasting and media domain. Several successful applications of these technologies now exist for media archives. Others are being considered to enrich second-screen applications or search engines.

MediaMixer is pleased to have been able to contribute to the report (Section 8), highlighting the use case of re-using media fragments from archived video footage (e.g. to lower cost of new media productions) and pointing to technologies and tools in the areas of Media Fragment Creation, Description, Rights and Management. This is a summary of our very own Core Technology Report, available to community members for free.

At the recent Internet of Education event Lyndon Nixon, co-ordinator of the MediaMixer project, spoke about the offer of MediaMixer technology to the e-learning domain. In particular, he presented how semantic multimedia technology can help online lecture video be split into fragments around distinct topics and mashed up into new learning offers, helping e-learning portals like VideoLectures gain more value from their materials as online learners derive more value from the same materials.
