New digital multimedia broadcasting technologies employed

TTA published T-DMB standards and Standardization is on progress.

T-DMB specification was legislated as ETSI standard and will be

legislated by ITU-R

T-DMB can provide TV, radio and various data services anywhere and

anytime & Mobile multimedia functions added to mobile phones

Various type of T-DMB receivers developed and is developing by many

electronic companies

Commercial T-DMB services launched in December 2005 around

Seoul metropolitan area, and will be available nationwide soon

China, Germany, England and many other countries consider T-DMB

services

7. Conclusion

According to emergence of digital technology in the field of broadcasting and convergence trend between communication and broadcasting technology, we should note that the advanced digital broadcasting standardization such as DMB, IPTV is being proceeded at the various standardization organizations.

It is necessary to share the information on Digital Multimedia Broadcasting standardization including mobile broadcasting between SDOs

Page 12: GSC: Standardization Advancing Global Communications 1 GSC-11 Standardization Status of TTA T-DMB (Terrestrial Digital Multimedia Broadcasting) 28 May

GSC: Standardization Advancing Global Communications 12

TV-like service at motion– Excellent mobile reception at max. 200 km/h

• VCD-like video quality on 5-7 inch LCD– Max 352*288 @ max 30 frames/sec

High quality audio service– CD-like quality audio broadcasting beats analog FM– Audio possibly with slide show

Data services– EPG, News, Weather, Stocks, Traffic Information etc.– Provision of local and remote interactivity

Mobile-phone-like multimedia service– free services like conventional TV– high-bandwidth data-box in my pocket for free reception (compared to mobile

communication network)
