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

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

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

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

2016/5/31
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
