In recent years, it has been realized that the success of multimedia services or applications relies on the analysis of the entire user experience (UX). The relevance of this paradigm ranges from IPTV to video-on-demand systems offering professional TV and user-generated content that is consumed and produced ubiquitously. To obtain a pleasurable and ubiquitous user experience a large amount of aspects have to be taken into account. Major challenges in this context include the identification of relevant UX factors and the quantification of their in influence on Quality of Experience (QoE).

In the particular scenario of ubiquitous production and consumption of content, 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.
In the support of ubiquitous QoE the acquired knowledge on the context and on identified parameters affecting users’ experience could be used to improve multimedia applications and their associated content delivery mechanisms.

* Workshop objectives
The objective of this workshop consists in collecting and developing know-ledge on the following three main topics defining the session structure
of the workshop:

– Context awareness for multimedia applications (video on demand, live broadcast,
3DTV, IPTV, social aspects, sensors, GPS, semantics, energy
efficiency)

– Content and context aware quality measurements (user generated& professional
content, live& on demand)

– Assessing and supporting QoE in ubiquitous scenarios
(constant and variable in influence factors).

* Research topics
The central research question of the workshop consists in determining key elements (including content and context information) for assessing and supporting QoE ubiquitously: These questions include, but are not limited to
the following topics:

– QoE in ubiquitous scenarios
– Context awareness
– Subj/ective and objective quality evaluation in the context of use, context-aware solutions
(situation specificity, interactivity, user-generated& professional content)
– Interplay between ubiquitous delivery and QoE support – 3D Multimedia and Free ViewPoint
– QoE support for interactive multimedia

* Submission
Workshop papers should not exceed a maximum length of four pages and follow the ACM Style Guidelines

Special Session on Perceptual Quality Assessment in Networked Video Applications

18th International Packet Video Workshop (PV2010)

Dec. 13-14, 2010, Hong Kong

http://www.mtrec.ust.hk/pv2010/

Special Session on Perceptual Quality Assessment in Networked Video Applications

Recent advances in video coding and wired/wireless networking have propelled many exciting networked video applications to the center stage of people’s life.  Due to the heterogeneity and dynamics of the network, such applications require dynamic adjustment of video coding parameters (including quantization, frame rate, frame size, and error resilience features) and error control mechanisms.  The decoded video may suffer from packet loss and delay jitter in addition to coding artifacts. From the perspective of the service providers, it is critical to have an effective way to measure or predict the end user satisfaction under different network conditions, and to adjust the system operating parameters accordingly. As a witness of such demand, there are ongoing standardization efforts to design hybrid quality metrics that use both bitstream information and decoded content as inputs to a video quality metric.  This special session will provide a forum for exchanging new ideas specifically important for networked video applications. Topics of interests include, but are not limited to:

  • Impact of spatial and temporal resolution on video quality
  • Effect of fluctuation of spatial, temporal and amplitude resolutions on the perceived quality
  • Non-reference and hybrid quality metrics
  • Impact of packet loss, delay jitter, and audio-visual synchronization in the quality of experience
  • Quality monitoring and feedback in networked video applications
  • Perceptually optimized error control
  • Services oriented quality assessment (Mobile video quality assessment, Stereo and multiview video quality assessment, HDTV quality assessment …)

Prospective authors should prepare and submit the paper following the instruction for the regular papers posted on the workshop website. Papers submitted to the special session will go through a regular review process. The authors are encouraged to inform the special session organizers about their intent to submit the paper with a paper title.

ETSI Workshop on Quality of Service, Quality of Experience

ETSI TC STQ, User Group and TC HF are very pleased to invite you to a workshop on Quality of Service, Quality of Experience / User experience, focusing on speech/multimedia conference tools.
You are receiving this email, as you attended an STQ workshop in the past. Please accept our apologies if you receive multiple copies.

The event will take place in the Espaces de Sophia in Sophia Antipolis, France, on 21st and 22nd of September 2010.

Bus shuttles (to and from the hosting site) in the Sophia Antipolis area will be organized and further information will be provided closer to the date of the event.

In the context of the Green Agenda, teleconference meetings appear to be a potential alternative to physical meetings. However experience shows that the quality of teleconference services offered to the users is of major concern. The definition of Quality of Service (QoS) and Quality of Experience (QoE) required for such systems is a challenge.

We are calling for papers dealing with any of the subjects below:

· Users expectations

· Feedback from users of their experience of the applications in various uses (eg medical teleconference, within vehicles, in the context of home networking, Standardization Bodies, in the educational domain …).

· What are the benefits of 3D technologies for teleconferencing?

· What are the needs for standardization to increase the number of implementations and tools?

· How to implement performance testing methodologies in the context of teleconferencing?

· What will be the next generation of electronic tools?

· What are the requirements and quality criteria for video when added to speech communications?

· What are the minimum requirements for rooms characteristics used for teleconferences?

· What are the approaches of other SDOs when implementing and using electronic tools for meetings?

· Conference bridges. What are the consequences when user equipment implement different bandwidth (narrowband, wideband, super wideband)?

Abstracts should be sent using the events before 5th June 2010.
Abstracts should not exceed 200 words.

Participation in the workshop is free of charge, and open to everyone !
