    Abstract: The present invention relates to an apparatus and a method for initializing reception of a broadcasting signal in a digital broadcasting system. The present specification discloses an apparatus for initializing reception of a broadcasting signal. The apparatus includes: a broadcast program receiving unit which receives a broadcast program including at least one of a video signal and an audio signal from a broadcasting station; a function control unit which turn on or off the broadcast program receiving unit and controls the volume of a sound unit; an initializing unit which controls the broadcast program receiving unit to automatically set a channel of a program preset by a user, when the broadcast program receiving unit is turned on; a display unit which outputs the video signal; and the sound unit which outputs the audio signal. Therefore, a user can select a channel well by allowing a DTV receiver to switch into a channel of a predetermined broadcast program automatically or forcibly when the DTV receiver is turned on.

    Abstract: PURPOSE: A transmission method of digital broadcast signals, a transmission device, a reception method, a reception device, and a transmission frame structure thereof provide a single consistent transmission frame structure supporting various transmission modes, thereby providing various forms of services to a user. CONSTITUTION: A stream providing unit (100) converts service components of each program into streams. A multiplexing unit (200) modulates the streams into a predetermined mode according to a transmission mode. A transmission frame generator (300) generates a transmission frame based on the stream information allocated to each sub-channel and the multiplexing information due to the transmission mode. The transmission frame includes a frame body including the data information in respect to the services provided by the transmission frame and a frame header including the multiplexing information of the transmission frame.

    Abstract: PURPOSE: A broadcast data transceiving method in a digital broadcast system and a device thereof are provided to obtain additional transmission capacity while maintaining reverse-compatibility with an ATSC mode. CONSTITUTION: A detector(362) determines whether a level of a main data symbol belongs to a first group. When the level of the main data symbol belongs to the first group, a mapping unit(366) maps the main data symbol in an extension level using a modulation value of additional data. When the level of the main data symbol belongs to a second group, a bypass unit(364) maintains the level of the main data symbol.
