|
| People now possess various home-networked devices that are capable of upgraded computing, extensible storage,
multimedia processing, and network connectivity functions. With broadband home networking technologies, such devices can perform
media content distribution in a home network and play shared media files in a networked fashion. When users with portable homenetworked
devices are free to move in residential areas, they can cause the so-called playing discontinuity problem because device
movement can tear down any ongoing network connections for data transferring and then terminate any ongoing media playing
services in home networks. To contend with this problem, this paper proposes a software architecture for seamless home multimedia
services in ubiquitous home computing environments. This architecture design contains three functional components, including
network connection, media transfer, and media playing functionalities, all of which are designed on the base of standard Internet
protocol suites. As a result of a lightweight software design, the proposed architecture is platform-independent and can be activated
inside an application-level execution context. Home-networked devices can incorporate this application-level software without need
to modify underlying hardware configurations, system kernel modules, and operating systems. Prototype development implements
the software packages and applications, which are able to keep ongoing media playing services from playing discontinuity and
interruption when home-networked devices move in an administrative network domain. Scenario demonstration shows that the proposed
software architecture is able to provide seamless home multimedia services with better user experience for multimedia entertainment
in residential environments. |
