DTMB

Abstract

DTMB - Digital Terrestrial Multimedia Broadcasting - is a Chinese standard which, like DVB-T - has the aim of broadcasting television economically terrestrially by digital means and with modern supplementary services. DMB-T was published in 2006 – at least in excerpts, as “GB20600-2006 – Framing Structure, Channel Coding and Modulation for Digital Terrestrial Broadcasting System”. It was renamed DTMB, having combined two proposals to form one standard in 2007. In one proposal, a multicarrier method was stipulated, in the other one a single-carrier method is suggested. The favoured proposal of the multi-carrier method comes from Tsinghua University in Beijing and was called DMB-T for a long time. The single-carrier method is called ADTB-T and originates from Jiaotong University in Shanghai. DTMB has similarities with DVB-T whilst ADTB-T is derived from the North American ATSC.
