Abstract: The transmitter has a pilot generation unit (120) for generating a predetermined pilot signal. A spectrum spreading unit (122) spreads a spectrum of the generated pilot signal for generating a spread spectrum pilot signal. A modulation unit (124) modulates the generated spread spectrum pilot signal for generating a spread-out and modulated pilot signal. A signal synthesizing unit (126) synthesizes a modulated broadcast signal with the generated spread-out and modulated pilot signal. Independent claims are also included for the following: (1) a channel tuning device utilizing a spread spectrum in a digital broadcasting system (2) a method for transmitting a spread spectrum control signal for channel tuning in a digital broadcasting system (3) a method for channel tuning in a digital broadcasting system.

Abstract: PURPOSE: A broadcasting apparatus of disaster information and a method thereof are provided to broadcast a disaster condition in a specific region. CONSTITUTION: Broadcasting information processing units(121-123) generate and modulate a second ETI(Ensemble Transmission Interface) frame. The second ETI frame includes channel and disaster information as a high speed information channel. The high speed information channel carries out control information about a general broadcasting information. A broadcasting information switching unit(130) selects the first ETI frame and the second ETI frame.
