Operating mechanism for device cooperative content on ubiquitous networks

We propose an operating mechanism for device cooperative content, which is a concept to provide new content on ubiquitous networks. There are two types of device cooperative content. The first is temporal synchronizing content and the second is semantical synchronizing content. Therefore, the content operation mechanism consists of two types of cooperative operation. Device cooperative playing plays various content synchronously after distributing user profile information to other accessible devices in setting up a cooperative playing environment. Device cooperative browsing is an interactive method, which can be used to browse related content for being content watched. Both operation mechanisms are based on multi-device operation, which are connected to a peer-to-peer network; the former operates cooperatively to find its own interests and maintains these around itself, the latter is a synchronous multi-device player. Multi-devices sharing common information might have common interest topics on various user devices. When new devices are connected to the environment, they detect suitable information through filtering, and obtain this from other devices on a local ubiquitous network. We describe this concept and discuss the device cooperative SMIL player and WebBoard, which are implementations of our concept.
