Video Quality Adjustment Model Supporting Mobility for Seamless Multimedia Service Delivery

Abstract:

Advanced multimedia computing technology is capable of providing user-oriented services for the user and the environment through context-awareness. This study seeks to provide seamless video delivery service with the focus on the user’s mobility patterns during a multimedia streaming service session. Mobility supporting technology which ensures the provision of seamless services can be classified into host mobility and user mobility. The former corresponds to host-level handoff while the latter refers to user-level handoff. In host-level handoff, the factors that directly affect the quality of video consumption are total distance between hosts, the distance for streaming resuming while user is in mobility mode as well as the screen size of the end host. The relationship among these parameters is analyzed by carrying out a user subjective assessment and an appropriate video quality model was developed, accordingly. The proposed quality model supporting seamless-mobility has a high correlation to the assessed quality and enables an adequate seamless mobility for multimedia service delivery.
