Abstract: A DTMB-based control system includes a carrier mode detector, a TPS decoder, a first latch, a second latch, and a latch controller. The carrier mode detector receives a number of NTPS and NCS of input signals to thereby produce an amplitude sign signal and a carrier sign signal for accordingly determining a carrier mode to be multi- or single-carrier mode. The TPS decoder receives the NTPS input signals and accordingly determines a codeword index signal. The first latch locks the amplitude sign signal and the carrier sign signal. The second latch locks the codeword index signal. The latch controller receives a frame number and drives the first latch to lock the amplitude sign signal and the carrier sign signal or drives the second latch to lock the codeword index signal.
