Perhaps the off-air DTV signals in China will be more widely used than in the U.S., and makers of DTMB demods can achieve some success. Or perhaps China can mandate that the receivers be included in all new TV sets, as the U.S. did, and create a guaranteed market.
DTMB "territory" is relatively small. DVB-C is primarily used in Europe. The products will roughly serve 2/3 of the world market. Just by market size alone is attractive enough for investors. Yet, where are the competitors in this space?
