Studium Generale (Prof. Hideaki Yoshino-Nippon Institute of Technoloy): QoE Assessment and Measurement in Communication Network
Prof. Hideaki Yoshino form Nippon Institute of Technoloy (NIT). Three aspects about “Quality” in Japan and Global Organization of Telecommunication :
1. Critical Evaluation
2. High User Expectation
3. Regulation.
QoE (Quality of Experience) methods and tools are definetely needed. Domain to measure the QoE of IPTV :
1. Pre Transmition domain
2. Network domain
3. Post Transmition domain.
QoE measurement is necessary when :
1. Before service is developed
2. After service is developed
3. After service is delivered.
Standardization activities on QoE assesment by its :
1. Methode : Subjective assessment Objective assessment
2. Media : Individual media
Three models of Objective Quality Assessment
1. Parametric Planning Model
2. Media Layer Model
3. Parametric Packet-Layer Model
Quality in Japan and global standardization :
1. Critical Evaluation in japan
2. High user expectation
3. Regulation : QoS and QoE requirement by law
QoE, the overall acceptability of application or services percieve subject by endure start from producer up to end user
QoE measurements of IPTU :
1. pre transmission
2. network
3. post transmission
Measurement of QoE time cousumis, expensive. Objective assessment with G.107 model, P1201, 61070 with benchmarking with P.863, J.341. Research topics in QoE :
1. Expand target services
2. expand assessment atributs
3. user
4. etc
5. design
6. input
7. control
