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 6. Brief

9. GSC: Standardization Advancing Global Communications 9 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
