Highlights from Presentation 1Home Network
Architecture and Logical Entities

• Main issues
• Focus on Management, Security, and QoS
• Transport technology independent
• Accommodate IP and non-IP home devices
• Logical Entities and Domains
• Portal Services Element
• Conclusions
• Flexible and expandable architecture allowing
  different domains
  
• Configurable PS functionalities
• Applicable for A/V contents to time critical
  services

Highlights from Presentation 2Bridging to CE
Devices across IP Domains

• Main issues
• Seamless access between IP domain and proprietary
  domains
  
• No change of the existing CE devices in the
  proprietary domains
  
• Common commands and common directory schemes for
  unified access
  
• Common protocol and secure access for inside and
  outside home
  
• Domain Gateway Architecture
• Conclusions
• Need Domain gateways for connecting IP and
  proprietary domains
  
• Home gateway is for connecting inside and outside
  home
  
• Define common commands and common directory
  information format

Highlights from Presentation 3Home Network
Service Aggregation Platform and Service
Collaborations

• Main issues
• Software based OPEN architectural Service
  Gateway
  
• OSGi platform Java-based software platform
• Service Aggregation Platform
• Service operation architecture on Service gateway
  
  
• Conclusions
• Needs for Service Gateway (SGW) to handle
  diversified services
  
• Service collaboration function will increase
  values of home services
  
• Some new standards for SGW is needed

6
Highlights from Presentation 4Digital
Television as Integrated Information Device

• Main issues
• Connecting ISDB to Home Network via Home Gateway
• Copt Right Protection for Digital Receiver and
  Digital Storage
  
• Home Server and RMP (Rights Managements and
  Protection)
  
• Conclusions
• ISDB is a solution of future broadcasting that
  shall be connected with Home Network
  
• Copy Right Protection is strictly required for
  Digital Storage Device
  
• Spreading Services are expected by Digital
  Television

7
Overview of issues in the session

• Architecture is required to terminate access
  networks and to control Home Networks.
  
• Architecture shall be independent from Transport
  technologies.
  
• Need Domain Gateway (DGW) for connecting IP and
  proprietary domains
  
• Common commands and directory schemes for unified
  access are required.
  
• Needs for Service Gateway (SGW) to handle
  diversified services
  
• Some new standards for SGW is needed
• Future broadcasting shall be connected with Home
  Network
  
• Copy Right Protection is strictly required for
  Digital Storage Device

8
Recommendations

• Basic Home Network Architecture is ITU-T Rec.
  J.190
  
• Needs enhancement to connect Proprietary Domains
• Common commands and directory schemes for unified
  access are to be specified
  
• Some new standards for Service GW is needed to
  handle diversified services
  
• Need mechanism (DGW) enabling broadcast services
  to connect with Home Network
  
• Copy Right Protection shall be specified in Home
  Networking environment

9
Follow-up actions

• Enhancement of ITU-T Rec. J.190 Series
• Works to be continued for
• Specifying unified access including Common
  commands and directory schemes
  
• Studying Service GW to handle diversified
  services
  
• Creating mechanism enabling broadcast services to
  connect with Home Network
  
• Inclusion of Copy Right Protection in Home
  Networking
  
• environment

10
Conclusion

• Agreed to further study for enhancement of Home
  Network Architecture based on ITU-T Rec. J.190
  Series
  
• Home Networking as a milestone toward Ubiquitous
  Networking
  
• Agreed to study mechanism enabling broadcast
  services to connect with Home Network
  
• Agreed to study Copy Right Protection in Home
  Networking environment
