The Media Technology
Research Group
It should just work!
Applied research for
the future!
The research area media technology is the study and practice of storage, distribution and presentation
of media including real-time media as audio, video, music and animations as well as non real-time
media such as images, text, graphics and other data. The research area also includes computer based
human interaction and other media related applications such as learning environments (both local and
net-based), distributed team-work, telepresence, distributed computer simulations, games and contextaware systems.
Storage of media includes technologies for efficient and practical storage of media including the
research about media database indexing, searching and retrieval of media objects as well as
knowledge representation. For efficient storage and distribution media coding is central.
Distribution of media includes design of distributed applications as well as protocols
for efficient network utilization during the distribution process. A central area is media
scalability where different forms of distribution over heterogeneous networks are
researched, where heterogeneous means both varying bandwidth as well as varying
network types. The primary distribution form is utilizing the Internet Protocol but also
interaction with other related distribution forms are included. Distribution also includes
research into new forms of media exchange within groups of distributed users as well
as the important aspects of information system security.
Presentation of media includes how different forms of media are presented to the
receiver. This includes various forms of user interfaces and presentation techniques as
well as efficient technologies for computer based presentation. Presentation also
includes research regarding alternative physical presentation forms such as wearable
computing devices.
Interaction includes how people can efficiently communicate using computers and
computer networks where both synchronous as well as asynchronous communications
are central. This subject includes natural language processing, computer vision and
computer speech processing.
The Media Technology research group at the Luleå University of Technology was founded 1995
and have until 2002 produced two PhDs, one Docent, and have currently 7 PhD students enrolled.
The group has published a great number of publications in both international journals and at
international conferences, received several best paper awards as well as several individual research
The group is today led by Dr. Peter Parnes together with Dr. Kåre Synnes. The research group
believes strongly that research results should both consists of academic publications of high quality
as well as industry near prototypes, i.e. prototypes that can actually be used. This approach led in
1998 to the creation of the company Marratech AB which now develops software for real-time
interaction over the Internet.
The research group has been part of several international EU research projects and has a long
experience from working in very large research and development projects. Previous and current
industry project partners include among others Telia, Ericsson, Frontec, Marratech, Teracom,
Philips, Thomson, Dassault, Bertelsmann. Non-industry partners include Centre for Distancespanning Technology, Centre for Distance-spanning Healthcare, Centre for Distance-spanning
Media, Centre for Distance-spanning Learning, The Swedish Research Institute for Information
Technology, UCL UK, KTH, and FramKom.
