1. IEC TC 100 Standardization of Common API for T-DMB receivers May. 20. 2008 IEC/TC100/AGS, Washington DC, USA

2. IEC TC 100 2 Contents Status of Standardization on T-DMB receivers Coverage of the Standardization

3. IEC TC 100 3 A series of international standards on T-DMB receivers are under way Series 1 : IEC 62516-1 : Terrestrial Digital Multimedia Broadcasting (T-DMB) Receivers - Part 1: Basic requirements ( IEC 62516-1 published as an IS on 03/2009) Series 2 : IEC 62516-2 : Terrestrial Digital Multimedia Broadcasting (T-DMB) Receivers - Part 2: interactive data service using BIFS (Binary Format For Scene) ( 100/1540/NP is in circulation by 07/10/2009) Series 3 : IEC 62516-3 : Terrestrial Digital Multimedia Broadcasting (T-DMB) Receivers - Part 3: Common API for T- DMB receivers (Preparation of NWIP is required) Standardization - Status

4. IEC TC 100 There are many receiver chipsets in the market They have their own Command Set API Solution for the development of T-DMB Software Standardization - Why needed? (1)

5. IEC TC 100 If the T-DMB Receiver chipset is changed, the software development cycle has to be started all over again to accommodate this new hardware.

(2)

6. IEC TC 100 There are various kinds of receiver chipsets in the market They have their own Command Set API Solution for the development of T-DMB receiver Software This causes heavy dependence of T-DMB software on receiver chipsets If the T-DMB Receiver chipset is once changed, the software development cycle has to be started all over again to accommodate the new hardware => Standardization of Common Command Set API is required Standardization - Why needed? (3)

7. IEC TC 100 Common API Standards in relevant technologies DAB : DCSR (Command Set API for Receivers) MediaFLO : Receiver API DVB : ETSI ES 201 812 MHP Specification DVB platform API Standardization - Why needed? (4)

9. IEC TC 100 T-DMB will be serviced not only in Korea, but also in Norway, France, and Indonesia soon as well. In addition to video delivery, T-DMB will be able to provide various kinds of additional services such as visual radio, BIFS, TPEG, etc. Implementing these services in software requires a significant amount of time and effort. A common API needs to be standardized for these application services in order to make implementation of inter-operable and reliable T-DMB software easier. Standardization - Why needed? (4)
