Workshop on Multimedia Quality in Virtual, Augmented or other Realities

ETSI TC STQ is organising a workshop on Multimedia Quality in Virtual, Augmented or other Realities. The event will take place in the ETSI Headquarters in Sophia Antipolis, France, on 10 - 11 May 2017.


TC STQ is responsible for standardization relating to terminals and networks for speech and media quality, end-to-end single media and multimedia transmission performance, Quality of Service (QoS) parameters for networks and services and Quality of Experience (QoE) descriptors and methods.

Objectives of the workshop

The workshop aims at covering all aspects of multimedia quality in different environments. We would like to cover the latest developments in this area especially under QoS and QoE aspects. ETSI is interested in fruitful discussion between researchers, implementers, operators, users and standardization bodies. This includes the topics speech, audio, video, tactile and haptics. Besides quality aspects, implementation/5G/architecture and management/monitoring aspects are also covered.

The workshop aims at connecting experts working in this area and providing them the opportunity to present their work, share their experiences and give possible input for future standardization.
