Apparatus and method for fine tuning of signals

The present invention relates to a signal reception apparatus and method. Demodulating the broadcasting signal transmitted from a signal transmission apparatus in the first main service channel data and the first high-speed information channel data, analyzing the first data and fast information channel and extracts the value of the hierarchical modulation mode. It extracts fast information data channel information for the broadcast signal using a hierarchical modulation mode value from the then demodulated into two main service channel data and the second high-speed information channel data, and the second fast information channel data. Using a high-speed information channel data information of the second high-speed information channel after the primary service channel data and enhanced services demultiplexes the channel data of the layers of the hierarchy outputted from the data generated by a plurality of broadcast services, a plurality of broadcasting services created choose one of the broadcasting services, plays a program. AT-DMB, the hierarchical modulation mode value, FIC
