2 Project Objective The objective of TEAHA is to combine the Home Control world with the Audio Video world through an open, secure, interoperable and seamless global home platform 2

3 Aims of The Project To create a platform that will be able to sustain a wide range of applications irrespective of protocols and type of networks used. The platform must be able to support different bouquet of services for the benefit of the customers. Operation must be easy and secured with an appropriate quality of service. Both Home Control and Audio Video applications must seamlessly co-exist on the same platform. To produce a demonstration system that will encompass the spirit of TEAHA. 3

4 R&D Activities The main R&D activities associated with the TEAHA project in support for a seamless interoperable/inter-working global home platform are: specification of an open and secure framework development of a low cost RF communication solution development of an ultra low cost powerline communication solution the development of advanced residential gateway subsystems 4

5 Key technologies Open Secure Middleware Framework Define and develop an open secure framework for seamless interworking Based on TAHI open architecture Convergence of worlds Protocols and standards. (MHP-OSGi-HAVi- UPnP-JINI..Konnex-Zigbee) Service Discovery Techniques. Define a network independent service discovery notation, Investigate new features such as service sub typing, service advertising, service browsing, service catalogue, eventing, garbage collection Security on the platform Investigation on security issues such as dynamic registration, and management of new components, dependability of registered components and privacy in the home environment. 5

7 Specification of an open and secure framework Adaptation of the TAHI Open Architecture to suit TEAHA requirements Use of a cluster based classification system (Taxonomy) for simplicity Application of Data and System security from conception Implementation of up-to-date Service Discovery Techniques 7

8 Middleware - TAHI Open Architecture. «A description of methodologies of an open architecture for technology and service delivery» The TAHI Initiative has defined an open architecture outline which provides guidelines on how to construct and deploy platforms for pervasive delivery of services. Main features of the Architecture The recognition of entity groups in the delivery of a service that are interdependent That each entity group will need (in sequence) an association with the next one That each entity may be described in terms of an Object that characterises the parameters of that entity That any service will need Agents to negotiate between its source and recipient entities, entity by entity That for some services the requirements of service delivery are different to those that control the delivery 8

14 Development of a low cost RF communication solution To validate the usability of low-cost, low-power wireless networking solutions (Zigbee) for future home applications. The Household Appliance Industry needs to improve the available communication components to be used in a mass market. The Zigbee Alliance is defining an ultra low-cost, low-power wireless networking solution, suitable for application such as remote control, home automation, toys and games, industrial sensors, meter reading etc. Integration of TEAHA concept into one of the prominent RF solutions (Zigbee) 14

15 Development of an ultra low cost powerline communication solution To investigate, define and develop an ultra low cost power line solution for seamless interworking Home Network Interface Proxy Home Network Ultra-low cost powerline Ultra-low cost connection In order to allow secure connectivity of some devices, an ultra low cost solution consists in physically separating network communication from the device, by including very simple dedicated connection from the device to the network communication systems. (proxy approach) investigate issues such as noise, compliance to EMC standards, coexistence with other powerline networks.

16 The development of advanced residential gateway subsystems To define and develop an end-to-end solution for the dynamic delivery of managed services and applications into the home, based on one or several Residential Gateway(s). Residential Gateway end-to-end solution The end-to-end solution will encompass a RG, a Gateway Operator- Aggregator, Service Providers. Enhancements in the three main components (Addition of Business Intelligence to the Aggregator, interconnection with legacy systems, exchange of information among subsystems by means of Web Services) Based on open architectures (TAHI) 16

18 Dissemination and standardisation Contribution to standardization bodies (OSGi, Konnex, EIBA, Zigbee Alliance ). Demonstrators to show advance in R&D activities. Dissemination (Ensure information of initiatives, especially into the company business units. Organization of documents, brochures, books,workshops, conferences, papers for journals ) Links/coordination to Forums, Initiatives, Alliances with common objectives Exploitation Plans 18
