Du Baichuan, former CTO of China’s State Administration of Radio, Film and Television has confirmed that “China will have two mobile TV standards by the end of this year: CMMB and TDBM”.

CMMB (China Mobile Multimedia Broadcasting) is based on a hybrid satellite and terrestrial network, originally developed by China’s Academy of Broadcast Science and Sarft. TDMB is a mobile TV standard using China’s home-grown 3G mobile telecommunication standard, TD-SCDMA (Time Division-Synchronous Code Division Multiple Access). TDBM was developed by Datong Telecom, a research body of China’s Ministry of Information and Industry (MII).
