To improve response time of time-sensitive application in a network using low speed communication link, implementation design of a middleware bundle adjusting bandwidth between applications is proposed and performance of the design is experimentally evaluated. The experiment shows that worst case delay of a high-priority packet is reduced from 4230 ms to 218 ms.
This paper presents the implementation process for an API that integrates interactive digital TV (iDTV) applications and home network (HN) services, mainly concerning issues of the Brazilian iDTV model. The research in this field is important because it represents current trends on the use of iDTV opening many business opportunities. With the convergence of service providers, modern communication...
In this paper, we investigate an integrated architecture to support interoperability among heterogeneous middle wares on home networks. We propose and implement a general middleware bridge to support device interoperability on different middle wares for efficient home networks. The IWFEngine(inter working function engine) architecture provides an interface for identifying and utilizing services among...
This paper gives the theoretical and technical research about home network architecture, three-layer home network protocol conversion, hardware and software's design and integration of home network, proposes a solution about home network architecture and home wired control network based on SoC. Specific study includes: home network general interface SoC, Home Gateway SoC, home network platform design...
Among the most promising applications provided by digital TV systems are the ones that enable TV-sets to work as the central processing unit of a house. This is supported by the extending of iDTV functionalities, taking into account its computer platform not only for application execution, but also for management of electronic devices services in smart homes, like a home gateway. In this context,...
Recent developments of information technologies are leading the advent of the era of ubiquitous healthcare service, which means healthcare services at any time and at any places. In a home, the ubiquitous healthcare service requires some context aware system for smart services using home network. In this paper, we propose a systematic design tool of a context aware system for ubiquitous healthcare...
As the core of digital home, RG(residential gateway) distributes services to diverse electronic appliances through different mediums. In this paper, we propose a new solution using a more intelligent STB(set top box) to fulfill tasks of RG. On the one hand, it integrates the two equipments together to cut the costs; on the other hand, it provides much more functions with good quality. We adopt the...
The home environment becomes ready to host distributed devices dynamically adapting to service availability and reacting to user location and user activity. Sensors, high definition rendering systems, home gateways, wired and wireless controllable equipments are now available. Many protocols enable connectivity and interaction between devices. However, challenges remain: protocol heterogeneity, interface...
