High Quality Multimedia Tools for Sophisticated Users

During 2015 the Multimedia Infrastructure innovation project (MMI2015) has continued UNINETT’s work towards a future infrastructure capable of satisfying high requirements to multimedia content and transport quality.

I MMI 2015 a fair amount of time has been spent collaborating with test-users from the domain of music and musical theaters. Department of Music at NTNU and Dokkhuset scene has been the most active user group, but other Norwegian institution including University of Tromsø and University of Oslo has joined in on experiments.

This user group, musicians and musical producers, has an very important and valuable quality. They have very strict requirements to sound quality as well as to latency aspects of both sound and video. For UNINETT, collaborating with such users is valuable. Very likely they represent the more general users of the future, i.e. the users UNINETT will be providing resources and services to.

During 2015 the MMI2015 project has contributed to several achievements.

  • Cribrum – a multi-display manager: MMI2015 has supervised a team of student (the screen team) from the Department of Computer and Information Science at NTNU in developing a user friendly open source software package for management of multimedia content in a multi-display infrastructure. Dokkhuset scene’s 8 screen infrastructure has been the target test bed. The resulting tool is operational and available on-line at https://sourceforge.net/projects/cribrum/  . Cribrum has already been applied in educational settings.
  • streamer.uninett.no: A foundation for a new version of this test-service for multimedia streaming has been developed and tested. The new service depends only on open source tools with ffmpeg as the core transcoder and segmenter. MPEG DASH was attempt applied as streaming transport technology. However it turns out that DASH is not yet straight forward supported in browsers on desktop, Android and IOS devices. The current version of the service hence applies HTTP Live Streaming as its transport format. By applying Momovi.com‘s open source HLS player for the browser, the streaming service makes content available on “all” devices with adaptive bit-rate control streaming as well as time-shift features. The finale “polish” to the service remains before it become available on-line.
  • High capacity music collaboration infrastructure: MMI2015 has been supporting NTNU’s work on establishing high capacity 10Gbps links to relevant rooms and halls for musical collaboration in the city of Trondheim. Three larger venues, Dokkhuset scene, Olavshallen, Rockheim and NTNUs orgelsal are now connected. Two studios at the Department of Music is also connected, enabling multiple students in parallel to test theirs skill in live production of concerts and events without needing to be on-site. Work on getting NRK, the Norwegian Television Broadcaster connected directly too is ongoing.
  • Business models for streaming at Dokkhuset scene: MMI2015 has supervised two Msc student in their work on a business model analysis for future multimedia steaming services at Dokkhuset scene.

Most of the activities persued in MMI 2015 has been suggested to be continued in a Multi media Infrastructure 2016.
