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

1. World-Wide Promotion Status of T-DMB
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)
