1st International Workshop on Standards and Technologies in Multimedia Archives and Records (STAR)

1st International Workshop on Standards and Technologies in Multimedia Archives and Records (STAR)

26th - 27th April 2010, EPFL Lausanne, Switzerland



The ability to effectively manage and protect digital multimedia content in creation, collection, preservation, and dissemination is increasingly crucial as digital technology continues to produce vast amounts of valuable and irreplaceable knowledge and information. The amount of such digital multimedia information is already huge, but as we speak it is still growing at unbelievable speed and to gigantic amount of such information.

The big questions are:  Can data generated yesterday be searchable and displayable by hardware and software today and in future? Will digital content created today be accessible and presentable throughout its lifecycle (i.e. also tomorrow)? How to deal with the large number and quite different incompatible multimedia archives? How to ensure some level of interoperability among them? What are the requirements for multimedia long term archival in general? What do we cover today in standards and what and where are the gaps?

To answer these questions (or at least some of them) the workshop aims to bring together archive professionals with technical experts working in the research, development and standardization in order to assist the alignment of user needs with the availability of technical solutions. The workshop will address with invited talks and panel discussions the following key topics:

  • End user requirements on preservation methods and formats
  • Digital archival projects - user expectations and experiences
  • Technical frameworks and architectures for multimedia archives
  • Trends in data modelling
  • Progress in digital preservation methods and archival formats
  • Interoperability issues and standardization efforts
  • Ingest and access methods for cooperation of archives

Special Issue on Multimedia Quality Assessment of IEEE Signal Processing Magazine


Special Issue on Multimedia Quality Assessment



The field of multimedia is maturing and one of the positive outcomes is the increasing number of new, innovative and improved products and services. It is, however, no longer sufficient to just add features to a multimedia product or service; it is also vital to measure the added value, in terms of quality, for end-users.  The era of user-centric multimedia has already begun and Quality of Experience (QoE) plays a central role, bringing a new and fresh look at the quality and performance of multimedia systems. In contrast to traditional QoS, which aims to capture the system-related characteristics, QoE is not restricted to subjective perception based on fidelity measures. Instead, QoE extends to user behavior/needs, appropriateness, context, usability and other human factors pertaining to delivered content. Evaluation of QoE requires comprehensive subjective quality assessment methodologies and objective quality metrics based on models of human perception, behavior, and sense of presence. These metrics must also incorporate such issues as end-to-end system issues, environmental context, user preference, and human-machine interaction.

The aims of this special issue are to provide researchers and professionals in the field of multimedia signal processing with well‐written tutorial‐style papers addressing the latest advances in the evaluation and assessment of multimedia quality. The targets are not only traditional media such as speech, audio, image and video, but also new types of emerging media.


Scope of Topics

-        Speech and audio subjective and objective quality assessment and metrics

-        Image and video subjective and objective quality assessment and metrics

-        Audio-visual quality assessments and metrics

-        Subjective and objective quality assessment and metrics for new media (UHD, HDR, stereo and multiview, 3D audio, haptics, etc.)

-        Human sensory models and their applications to media quality assessment

-        Standards, and benchmarking efforts in media quality assessment

-        Applications of media quality assessment

-        Multimedia quality of experience assessment and metrics

Quality of Experience for Multimedia Content Sharing at EuroITV2010


Quality of Experience for Multimedia Content Sharing at EuroITV2010
Place: Tampere, Finland
Time: 9th June 2010

Workshop web site: http://dcti.iscte.pt/events/qoemcs/


- 1st March 2010: Workshop paper submission
- 19th March 2010: Notification of acceptance
- 5th April 2010: Camera-ready submission
- 9th June 2010: Workshop at EuroITV 2010

In recent years, it has been realized that the success of multimedia services or applications not only depends on Quality of Service (QoS) parameters but also relies on the analysis of the entire user experience (UX).
The relevance of this paradigm ranges from IPTV or video-on-demand systems for distributing and sharing professional TV to user-generated content over the web. To obtain a pleasurable user experience far more aspects than QoS have to be taken into account. Major challenges in this context include the identification of relevant UX factors and the quantification of their influence on Quality of Experience (QoE). In particular, context awareness and assessment of users' expectations play an essential role. This is further justified by the emergence of new multimedia enhancement techniques, notably 3DTV and Free Viewpoint.
Future Internet architectures under current research are also promising on the possibility to accommodate protocols and policies that take QoE issues into consideration. Consequently, acquired knowledge on the context and on identified parameters affecting users' experience could be used to improve media delivery.


The objective of this workshop consists in collecting and developing knowledge on the following three main topics defining the session structure of the workshop:
- Context awareness for multimedia applications (video on demand on the web, content sharing, user-generated & professional content, IPTV, social aspects, sensors, energy efficiency)
- Content and context aware quality measurements (user-generated & professional content, live & on demand)
- Content and context aware interplay between media service/applications and network strategies. Namely, QoE support in the future internet architectures.


The central research question consists in determining key elements (including content and context information) for QoE assessment and evaluation of "web.sharing.tv.content" and to use this information to shape the future internet.
- Context awareness
- QoE for content sharing over the web and for IPTV
- Subj./Obj. quality evaluation in the context of use, context-aware solutions (situation specicity, interactivity, user-generated & professional content)
- Media Transmission over the Future Internet
- 3D Multimedia and Free ViewPoint
- Interactive multimedia QoE support
