Process of Digitization of Terrestrial Television Broadcasting

MIC

1997

・Technical Standards for DTTB were established in E.U (DVB-T) and U.S.(ATSC)

1998

・DTTB started in E.U (DVB-T) and U.S.(ATSC)

1999

・Technical Standards for DTTB were established in Japan (ISDB-T).

2000

・Technical standards for Digital Terrestrial Sound Broadcasting were established in Japan. ・Planning of DTTB station channels.

2001

・Development of institutions for digitization of Terrestrial Television Broadcasting.

・Support center for R&D of DTTB in Japan opened. (Shared use of facility, Organization of Communications and Broadcasting)

(Revised part of Basic Plan Popularization of Broadcasting and Use of Broadcasting Frequency)

2003

・DTTB started in Japan (in three metropolitan areas). ・Start of trials for practical application of Digital Terrestrial Sound Broadcasting in part of Kanto and Kinki areas.

ISDB-T is the newest DTTB system and as such includes the latest technology 2

Key Points for Introduction ISDB-T to Indonesia MIC

➢ Adaptability of ISDB-T ・ In Japan, the 6MHz bandwidth is assigned to One Digital TV channel. ・ Of course, ISDB-T technologically adapts the 8MHz bandwidth. →If a market is established, then LSI encoder which is a key component to come into practical use to enable TV reception to adapt the 8MHz will be supplied.

➢ Technical Cooperation ・ Dispatch a mission and implementation of demonstration with regard to broadcasting for mobile reception. ・ Fostering of broadcasting technical experts. →Cooperation to establish channel planning based on Japan’s know-how. 18

Outline of Technical Cooperation Project MIC Project Title “The Project on the Capacity Development of the Ministry of Communication and Information Technology concerning Broadcasting Strategy Formulation and Planning”

Overall Goal Broadcasting administration is properly conducted in Indonesia.

Project Purpose The Ministry of Communication and Information Technology’s function concerning strategy formulation and planning on broadcasting is strengthened.

Outline of Project 1. The Project aims toward the capacity development of the Ministry of Communication and Information Technology concerning the strategy formulation and planning on broadcasting. 2. The strategy and plan on broadcasting will be considered taking account of the following policies: 1) Policies for the introduction of digital broadcasting in Indonesia, 2) Policies for the nationwide dissemination of broadcasting in Indonesia. 3.

Summaries

MIC

¾ Rapid diffusion of mobile phones indicates that diffusion of terminals coupled with mobile phones is sooner than renewing fixed TV receivers. ¾ Additional TV channel is not necessary, in the midst of the growing expansion of demand for frequency in the case of ISDB-T. ¾ High-quality audio broadcasting and/or data broadcasting can be provided together with One-Seg broadcasting in the same investment (transmitter, network Terminals etc.). → ISDB-T can be the most suitable DTTB system for Indonesia. 21
