Korean mobile television broadcasters using terrestrial digital multimedia broadcasting (T-DMB) are expanding the number of channels and testing e-commerce features of the mobile television service:

The new T-DMB channels have existing channels scrambling to up their game. KBS, one of the three national networks that provides mobile television broadcasting, and U1 Media are some of the T-DMB operators that will start their trial services for ``DMB 2.0,'' an interactive version of mobile television, this month.

DMB 2.0 allows viewers a limited range of electronic commerce and other data-based services, and the broadcasters are in talks with mobile telephony operators such as SK Telecom to develop and test ``mobile home shopping'' and other interactive services. The interactive mobile television services are eyeing a commercial launch by the year's end.
