In the continuing saga of the Chinese government pondering which of its own proprietary mobile television standards to require, Du Baichuan the former chief technical officer of the country’s State Administration of Radio, Film and Television (SARFT), says the country will have two protocols by the end of the year: China Mobile Multimedia Broadcasting (CMMB) and Terrestrial Digital Multimedia Broadcast (TDMB), reports EE Times.
The article says, “CMMB…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).”
Other standards
EE Times says Du discounted another Chinese protocol, DMMB (Digital Mobile Multimedia Broadcast), because there have been delays in offering terrestrial digital TV as well as problems of compatibility between DMMB’s wideband and narrowband layers. Du also wasn’t favorable towards T-MMB (Terrestrial-Mobile Multimedia Broadcasting) and CDMB (China Digital Multimedia Broadcasting).
The Chinese government hopes to have CMMB-based mobile TV in some 60 cities before the 2008 Olympic Games in Beijing.
