Digital Terrestrial Multimedia Broadcast
DTMB (Digital Terrestrial Multimedia Broadcast) is the TV standard for mobile and fixed terminals used in the People's Republic of China, Cuba, Hong Kong, and Macau.
Overview
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 being the unique standard, so the final decision was to opt for a double standard, merged with theTIMI 3 standard, responding to a need for backward compatibility.
The DTMB was created in 2004 and finally became an official DTT standard in 2006.
