In this paper, we present a novel software architecture providing the connected multimedia services through networked embedded systems. The connected multimedia service means that a multimedia session is preserved even though an end-user moves from one computing environment to others. For getting the immediate multimedia services, all that he has to do is to carry a small mobile pad, such as PDA or cellular telephone, which shows a list of devices that he can use as I/O devices of the on-going multimedia session. He does not have to re-setup the session. When he clicks and selects the proper devices among the devices listed on the pad, the session is immediately migrated to the selected device. We, in this paper, present our novel mechanism using well-developed and commercialized protocols such as SIP and X.10 to support this new paradigm of ubiquitous multimedia services.
