China narrows final mobile TV spec to CMMB, TDBM
September 13, 2007
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).
