Digital Terrestrial Multimedia Broadcast

DTMB (Digital Terrestrial Multimedia Broadcast) is the digital TV standard for mobile and fixed terminals, developed in the People's Republic of China. It is used here and in both of their special administrative regions (Hong Kong and Macau), and also in Cambodia, the Comoros, Cuba, East Timor, Laos and Pakistan.


Previously known as DMB-T/H (Digital Multimedia Broadcast-Terrestrial/Handheld), the DTMB is a merger of the standards ADTB-T (developed by the Shanghai Jiao Tong University), DMB-T (developed by Tsinghua University) and TiMi (Terrestrial Interactive Multiservice Infrastructure); this last one is the standard proposed by the Academy of Broadcasting Science in 2002.

At first, neither Shanghai Jiao Tong University nor Tsinghua had enough political strength to make their own technology become the unique standard, so the final decision was to opt for a double standard, merged with the TIMI 3 standard, responding to a need for backward compatibility.

The DTMB was created in 2004 and finally became an official DTT standard in 2006.
