Open Issues and Challenges for Standardization of QoE Need for Resources Testing is expensive & labor intensive Industry wants No-Reference Models Difficult technical problem High Quality Test Material (esp. AV & 3DTV) 3DTV QoE Subjective methods Objective methods Telepresence QoE (Question in SG12) Joint Efforts (JEG and JEG-Hybrid) vs Competitive See VQEG JEG-Hybrid Call for Proposals and Participation: 4
