In this paper, we propose QoE assessment model for video streaming service such as IPTV and VoD using QoS parameters in wired-wireless network. Existing perceptual quality assessment models are unsuitable for experienced quality assessment of a streaming service which passed through the IP-based network because they only take account of the characteristic of used codec and bit rate. However, QoS parameters for measuring video experienced quality must be considered because reliable delivery of real-time video streaming services is guaranteed by the network performance. Network and service providers can predict perceptual quality and quality satisfaction using the proposed model. Also, they can provide optimal service environment through selection of video streaming data rate and network traffic control based on video QoE assessment model.
