digital multimedia broadcast terrestrial/handheld (DMB-T/H)
DMB-T/H is the terrestrial mobile TV technology used in China and Hong Kong, also known as Digital Terrestrial Multimedia Broadcast (DTMB). This is in contrast to China Multimedia Mobile Broadcasting( CMMB), which is a hybrid terrestrial- satellite technology.
Digital Multimedia Broadcast Terrestrial/Handheld (DMB-T/H) operates in the UHF range between 470 MHz and 760 MHz and uses single- carrier as well as two-carrier modulation schemes, including Time Domain Synchronous Orthogonal Frequency Division Multiplex( OFDM), TDS-OFDM, Quadrature Phase Shift Keying( QPSK), and Quadrature Amplitude Modulation (16QAM, 64QAM). The terrestrial reception range is said to be 10 km further than with DVB-T, which is used in Europe. In addition, reception is said not to be limited even at speeds of 200 km/h.
