Abstract: The Internet streaming is changing the way of watching videos for people. Traditional quality assessment on the cable/satellite broadcasting system mainly focused on the perceptual quality. Nowadays, this concept has been extended to Quality of Experience (QoE) which considers also the contextual factors, such as the environment, the display devices, etc. In this study, we focus on the influence of devices on QoE. A subjective experiment was conducted by using our proposed AccAnn methodology. The observers evaluated the QoE of the video sequences by considering their Acceptance and Annoyance. Two devices were used in this study, TV and Tablet. The experimental results showed that the device was a significant influence factor on QoE. In addition, we found that this influence varied with the QoE of the video sequences. To quantify this influence, the Eliminated-By-Aspects model was used. The results could be used for the training of a device-neutral objective QoE metric. For video streaming providers, the quantification results of the influence from devices could be used to optimize the selection of streaming content. On one hand it could satisfy the QoE expectations of the observers according to the devices, on the other hand it could help to save the bitrates.
