UPnP based intelligent multimedia service architecture for digital home network

Demand of multimedia contents in home network is growing rapidly and UPnP is expected to bring better multimedia experience with various A/V devices. However, UPnP A/V architecture, which allows the multimedia contents to be shared between A/V devices, is limited to the environments where interoperable contents format and identical network protocols are used. In this paper, we propose an intelligent multimedia service framework which enables A/V contents to be adopted and shared according to user multimedia environments. We design and implement our multimedia service architecture based on UPnP A/V service and MPEG-21 multimedia framework
