Digital Terrestrial Multimedia Broadcast - Overview

Overview

The DTMB is a merger of the following standards: ADTB-T (developed by the Shanghai Jiao Tong University, Shanghai), DMB-T (developed by Tsinghua University, Beijing) and TiMi (Terrestrial Interactive Multiservice Infrastructure), which is the standard proposed by the Academy of Broadcasting Science in 2002.

At first, neither Shanghai Jiao Tong University nor Tsinghua had not 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 of backward compatibility.

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