MEDIAMOSA TRANSCRIPTING TECHNOLOGY

• The number of AV-archives on the Internet increases rapidly

• Archiving is not enough: disclosure and reusing is required!

• The use of speech technology is needed (Reduce human effort).

Disclosure of audiovisual archives

Huge amount of workand no time-coded relations with video

Adding metadata, the traditional approach:Manual annotation




Adding metadata, the new approach:Exploiting Speech technology for metadata generation

Speech Recognition(Speech-to-Text)Time-coded Transcript

Indexing and Search:Search on fragment level

Community Development Projects

MEDIAMOSA DRUPAL MODULES AND SDK

Drupal 6




DEVELOPMENT MEDIAMOSA FRONTEND

• Support for basic functions like:federative login, screening, uploads, transcoding, metadata, playback, collections, search.

• Works together with MediaMosa 3.x.

• Based on Drupal CMS and makes use of the MediaMosa Construction Kit (Drupal Modules).

• Skinable: easy to change template to change look and feel.

• Installable as a ‘ready to use’ frontend application or as a SURFconext service.




Next Steps• SURFnet funding for development ends 1-1-2012

• SURFnet is ending enduser services like SURFmedia as of 1-1-2013

• Dutch education is looking for alternatives:- MediaMosa in the Cloud?- MediaMosa as a service of SURFconext?- Alternative video services as a service of SURFconext?- Using MediaMosa as an institutional service?


The role of the Community becomes more and more important!

• Future of MediaMosa depends on it.• Secure commitment from educational

institutes.



MediaMosa Funding

• SURFnet/Kennisnet Innovation Program (until 1-1-2012)

• Sponsoring from SURFnet / Institutions / Partners / Developers

• Contributions from MediaMosa Community


SURFnet’s decision to end enduser services like SURFmedia will boost the uptake of MediaMosa.

The role of the Community becomes more and more important!

MediaMosa is there to stay!
