e-Japan Priority Policy Program: Content as well as Networks
January 22, 2001
http://www.kantei.go.jp/foreign/it/network/priority-all/index.html
1. It is stipulated in “the Basic Law on the Formation of an
Advanced Information and Telecommunications Network
Society” that enrichment of content shall be promoted
through close linkage with expansion of advanced
information and telecommunication networks.
2. The IT Strategy Headquarters of Japan set the goal in the
e-Japan strategy that within five years, at least 40
million household will enjoy continuous connection
(ultra) high-speed Internet services. To achieve the goal
effectively based on market principles, killer content is
indispensable in demand boosting.

3
Approaches toward the Goal
 Services envisioned in the goal




are provided via the Internet or another network beyond that?
are affordable for everyone?
have human-machine interfaces as simple as televisions?
are media-rich and intelligible for everyone?
 Technologies envisioned in the goal
 High-speed Internet: xDSL to FTTH
 Information sharing platform
 And we are pursuing both approaches through
market creation of HIKARI (optical) services.

Evolution of Optical Networks in Japan
While optical networks is spreading throughout Japan as far as facility is
concerned, broadband services over them are still in their infancy.

What is HSAC ?
HIKARI Service Architecture Consortium (HSAC)
aims to make “HIKARI Service Platform” a reality.
- The Platform provides consistent interfaces for both senders and receivers.
- The Consortium studies functional models of HIKARI services and
requirements for the Platform.
- Study reports of HSAC are completely open to everyone.
http://www.hikari-sac.org/e/index-e.html
- Market creation of HIKARI services is in progress in
collaborated HSAC-based companies.

HIKARI Service Terminals: Types 1 to 3
1) Type 1 (HIKARI Service operation on an inexpensive and simple dedicated terminal)
Simple dedicated terminal (Television)
• Provides functions to receive the basic service
• Limited video display capability
• Limited web browsing functions
2) Type 2 (HIKARI Service operation by a combination of legacy terminals)
Existing video terminal (Digital Television / Set Top Box)
•
•
•
•
Provides functions to receive the basic service
Supports some of the extended function services (Extended function 1)
Provides a Java execution environment for applications
Limited web browsing functions
3) Type 3 (Full capacity for rich and high grade services provided only by HIKARI Service)
HIKARI Service dedicated terminal
• Provides all basic functions and extended functions and handle the highest quality
video of HIKARI Service.
• Supports broadband net-live service functions that allow a user to enjoy flexible
visual perspectives such as multi-angle video.
• Provides realistic, large-screen video for the bi-directional communication service,
with precise audio localization.

Next Step:
Toward HIKARI Market Creation
Market creation of HIKARI services is in progress in
collaborated HSAC-based companies.
-Advanced RTSP is proposed in the HSAC Report (IR
Appendix) and study is going on.
RTSP: Real Time Streaming Protocol
- NTT, Hitachi, and Panasonic begin Joint Research on
Protocols of HIKARI Commerce Services
