This paper proposes a scheme of user-assisted QoS control by media adaptive buffering for user-assisted Quality of Experience (QoE) enhancement. The scheme consists of two modes: a manual mode and an automatic mode. Users can switch these two modes according to their inclinations. We deal with four QoS control schemes for comparison: the manual mode only, the automatic mode only, the switching scheme...
This paper deals with audiovisual and haptic interactive IP communications and designs a multidimensional QoE monitoring system with the QoE estimation in real time. For the estimation, we carry out regression analysis between QoE and application-level QoS and obtain equations for the estimation. We measured the application-level QoS and made a subjective experiment by assessing QoE multidimensionally...
For audiovisual and haptic interactive IP communications, we propose a media adaptive intra-stream synchronization control scheme, which exerts control suitable for each media. We assess QoE (Quality of Experience) of the following three intra-stream synchronization control schemes: 1) media adaptive buffering, 2) Skipping & buffering and 3) buffering. Schemes 1 and 2 are examples of the media...
