DTMB Intake Test Suite

Chinese government officially launched DTMB standard in 2006. DTMB was commonly known by two different modes, multi-carriers and single-carrier. The former is similar to DVB-T standard, while latter one roots from ATSC standard.

Since 2007, many cities have started DTMB live broadcasting and dispatched free STBs to consumers. For example, CCTV is broadcasting MPEG-2 HD trial signal in Beijing metro area.

DTMB is also chosen by Hong Kong authority as digital terrestrial broadcasting standards, incorporated into Hong Kong OFTA 1108 standard.

Unlike counterparts in European countries, big cities in China selected cable network broadcast content delivery in city/urban area, while terrestrial broadcasting targeting mainly for rural and remote area, and emergency broadcasting.

Since our head-end system have been involved in many trials, we understand the broadcaster requirements and service allocation strategy.
