screen by 1080i and 720p system

• Simultaneous broadcast (standard

quality ) of max. 3 channels

Semi- HD by 480p

• The supplemental information

service by text and picture

• By-directional service with Inter-net
• 1 segment simulcast TV and/or supplemental

service which transmission system is robust against fading and multi-path of mobile reception

• By-directional service with mobile-phone

network

Examples of Business model of terrestrial digital broadcasting

The world of the Internet

• Bi-directional/multi-functional service
• Broad-band (ADSL, fiber to the home)

The world of cellular phone

• 70 million users in Japan-
• anytime, anywhere-
• I-mode, FOMA
• Co-operate with Internet
• Clear picture quality even though SD and high-

quality sound for CM and TV program

• Home-theater with wide screen/high quality picture

and sound

• Multi-lingual and/or stereo
• Movie and sports event with 5.1 surround audio

High-quality and multi-functional sound broadcasting

• clear picture without ghost

and/or noise

Digital cinema related business

• The digital cinema production by 24P

and/or 30P

• Contents production for multi-use(

movie, TV and DVD, broad-band, etc.)

• e-cinema theater business

Step by Step Enlargement of Cover Area

Digital Terrestrial Broadcasting has start in 3 area (Tokyo(Kanto), Nagoya(Tyukyo), Osaka(Kansai) on

• Dec. 1, 2003

At early stage, transmitter power is suppressed to avoid interference to analog TV channel, but step by step increase the transmitter power and finally reach to full power operation. In other area, Digital terrestrial broadcasting will start during 2004-2006.

system should treat both analog TV program and Digital TV program simultaneously. -Show the outline of TV Tokyo master system as an example

Transmitter : Digital Transmitter should be separately

• prepared. - Show the block-diagram and out-of-view of

Tokyo tower transmitter as an example

Antenna: 3 area starting at Dec. 2003, analog TV channels

are mainly located in VHF Band, therefore, antenna for Digital Broadcasting should be prepared separately. -Show the out-of-view of Tokyo tower as an example

Step 2-b: Selection of standard system & evaluation

• Select the Standard for DTTB
• Trial first! At first, Check its own performances and functions (HDTV

and/or SDTV, fixed, mobile & portable use, Inter-operability with communication network,etc)

• Commonality between other broadcasting-media

Digital satellite, DTTB, Digital Audio,Cable, etc

• Harmonize to Spectrum planning, Spectrum utilization efficiency
• Study, evaluation, proto-type test & technical evaluation

Decide the standard system

Step 3-a: Planning & estimation of digitalization(details)

• Select the spectrum:
• which frequency band? -Bandwidth/channel, -Period of simulcast

both analog and digital,

• Movement scenario from analog to digital
• Channel planning
• Transmitter site locations and frequency allocation
• Service configuration in digital broadcasting system
• Which types of Video/Audio format
• Data-broadcasting
• Receiving type ; fixed, mobile, portable
• Commonality and Inter-operability with Communication

Conclusions

• ISDB-T is the most flexible DTTV standard
• ISDB-T showed the best results in Brazil’s comparison test. The

similar results were obtained in Singapore and Hong-Kong trials

• The sales of Digital TV receivers reached more than two

millions and will increase rapidly around 2006 in Japan

• The analog channel re-arrangement is the first big challenge
• Developments of ISDB-T one-segment receiver and its

components were announced in the end of 2003 in Japan. Mobile TV broadcasting will be launched in 2005.
