摘要
The present invention is a method and apparatus for hierarchical modulation is a modulation mode detection signal transmitted from the terrestrial DMB system applied relates. ; To this , the present invention does not detect the modulation applied to the second layer were combined signal is input to the first signal and the hierarchical modulation signal inputted to the mobile broadcast service and pre- divided in to one or more signals in accordance with the time interval after inserting a sequence for encoding / decoding in each of the divided signal, and provides the modulation mode detection signal transmitting method for transmitting the combined again. In addition, the first signal processing unit for processing a signal to be input to the present invention is a mobile broadcast service; A second signal processor for processing a signal to be input to the hierarchical modulation; And combining the first signal and the second signal divided by time intervals, and by inserting a sequence for encoding / decoding the divided signals to provide a modulation mode detection signal transmitting device including an insertion sequence to be transmitted. ; According to the present invention, the receiving end of a mobile broadcast system can easily detect the modulation method applied to the newly added signal, it is possible to use a plurality of modulation schemes at the same time it is possible to improve the data rate further.
