Multimedia Quality of Experience (QoE) Current Status and Future Requirements

Multimedia Quality of Experience (QoE)
Current Status and Future Requirements

Multimedia Quality of Experience (QoE): Current Status and Future Requirements discusses the current status of QoE (Quality of Experience) research, providing guidelines on QoE assessment and management practice. Moreover, it covers many different aspects of QoE research, including definitions, standardization (ITU, ETSI, IEEE, IETF), measurement, management, and architectures. In addition, the authors bring together contributions from recognized experts (worldwide) in the area of subjective and objective QoE video assessment.

• Discusses the current status of QoE research; reporting the latest advances from various standardization bodies
• Provides guidelines on QoE assessment and management practice
• Explores methods, means, and architectures of QoE
• Considers future requirements of QoE
