Winter School Video Lectures now available

Firstly, an acknowledgement that we successfully held our Winter School on Multimedia Processing and Applications at the beginning of this year co-located with the MMM2014 conference in Dublin. 30 international attendees, mostly PhDs and young researchers, were present for a set of technology centred presentations by MediaMixer experts and industry centred presentations by research project leaders in areas such as broadcasting, digital preservation and the Internet of Things.

The student Siriwat Kasamwattanarote from the National Institute of Informatics, Tokyo, Japan won the school Best Poster award for work done on “Tell me about TV commercials of this product”.

The Winter School talks covered the latest technological developments in the area of multimedia processing (media analysis, media annotation, media rights management) and of emerging multimedia applications (in the Sensor Web, audiovisual archives, TV broadcasting, digital preservation and e-learning domains). We didn’t want to keep this purely for the 30 attending students, so now all of the talks are published online courtesy of VideoLectures.NET:

[UPDATED] Managing your Media Fragments Rights – next Webinar on Feb 3, 1130 CET

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

Demo of semantic technology for copyright management of User Generated Content

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.

See the demo video.

Test the online prototype.

 

Linked Data: the Entry Point for Worldwide Media Fragments Re-use and Copyright Management?

We are delighted to announce that the MediaMixer partner UdL’s presentation entitled “Linked Data: the Entry Point for Worldwide Media Fragments Re-use and Copyright Management?” has been invited to be presented at the 2013 Semantic Technology & Business Conference – NYC.

Roberto García Gonzalez will present on the conference 1st day, 2nd October 2013, this MediaMixer case study on future Content Management:

“One of the biggest barriers for the uptake of a Web of Media is the availability of easy ways to reuse media fragments and manage their copyright. Existing proposals provide limited solutions or find it difficult to scale to the Web. MediaMixer contributes state of the art techniques for media fragment detection and semantic annotation.

This is complemented with copyright management integrated into the Web fabric, using Linked Data principles and reasoning based on a Copyright Ontology. Altogether, it can make possible to navigate the Web retrieving the metadata describing a piece of content to be reused, linked to the agreement about its copyright, the parties that will share the revenue, etc.

A typical MediaMixer demo involves:

* Fragmenting media assets

* Annotating them using semantic descriptions

* Modeling licenses, policies,… using the Copyright Ontology

* Exposing them for fragment level retrieval and re-use, including copyright reasoning”

Semantic Copyright Management of Media Fragments being presented at DATA2013

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.

“Copyright for Media Fragments” to be presented at the Metadata Developer Network Workshop

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.
