3. Highlights from Presentation 1 “Review of Home Network Services based on Open Services Gateway”
Home services are delivered by gateways based on OSGi specifications
Some relevant European projects on the home services based on OSGi specifications

4. Highlights from Presentation 2 “Home Server/Network System toward Digital Broadcasting”
Introduction of home server/network-related TC100 activities
PC is leading the home network with network media player
Broadcasting services based on home server will drive gateway function between in-house network and access network
DRM is the key issue for A/V network deployment

5. Highlights from Presentation 3 “Service and System Model for Interworking in Home Network Environment”
Overview of standardization activity for interworking in DHF (Digital Home-networking Forum)
Home Network should be “network” rather than “link” for exchanging data between devices.
Focus is given to directory service for discovery of service and device
ITU-T SG16 is extending scope to multimedia systems in home network.
More standardization is needed on service integration, new services, NGN

6. Highlights from Presentation 4 “Integrating Cellular and VoIP Services Using In-Home Wireless Technologies”
Cellular subscribers are increasingly using their cell phones at home, wireless substitution for wireline telephony will likely drive home-based usage even further
Use of in-home wireless technologies as the over-the-air interface for cell phones within the home will meet the rapidly increasing capacity demands in residential areas
Integration with a Broadband Voice over IP network provides a signaling and transport mechanism for the voice traffic, as well as enables a variety of interesting features

7. Overview of issues in the session
Components of the home service provided in the home network environments are:
Internet access (web, , ….)
Audiovisual, including conventional and storage-based TV broadcasting
Telephone
Tele-control, appliance management, home security
Those components should be provided not only separately but also combined seamlessly to form integrated home services.

8. Recommendations
Write more scenarios of the integrated service that capitalize on the availability of the mentioned component services, such as a service merging broadcasting and telecommunication
From those service descriptions, derive requirements to the home networking architecture.

9. Follow-up actions
Go back to each Study Group with the given information and views, and study on issues specific to the SG in the home networking and home services area
In ITU-T SG16, consider multimedia services in the home network environments, add H.300-series system as a component
Consider if the current H.300-series specifications are sufficient for the home network use, for example any problems involved in the communication via the home gateway

10. Conclusion
This workshop has provided various ideas surrounding the home services as a good stimulus for exploring new multimedia services and systems in SG16 (or its successor)
Many thanks to the four speakers, Michal Lisiecki, Keiichi Murakami, Keiichi Hibi and Ed Miller, for their valuable information and insight
