Session 3 Home Network Architecture Conclusions & Recommendations Mayumi Matsumoto NEC Magnus Communications, Ltd. 2019/2/16

Presentations in Session Home Network Architecture and Logical Entities/ Steven Saunders, CableLabs Bridging to CE Devices across IP Domains / Mayuko Tanaka, Hitachi Ltd. Home Network Service Aggregation Platform and Service Collaborations / Nobuo Fujii, NTT Digital Television as “Integrated Information Device”/ Haruo Okuda, NHK 2019/2/16

Highlights from Presentation 1 “Home 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 2019/2/16

Highlights from Presentation 2 “Bridging 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 2019/2/16

Highlights from Presentation 3 “Home 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 2019/2/16

Highlights from Presentation 4 “Digital 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 2019/2/16

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 2019/2/16

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 2019/2/16

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 2019/2/16

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 2019/2/16
