    Abstract: The present invention relates to a transmission method, a transmission apparatus, a reception method, and a reception apparatus of a digital broadcasting signal that can add frame header information to a front portion of a transmission frame in a transmission system for digital broadcasting to thereby determine a different transmission mode, modulation level, hierarchical modulation, error correction code, and the like for each temporally different transmission frame, and a transmission frame structure thereof. The transmission frame structure includes a frame header containing multiplexing information of the transmission frame, and a frame body containing data information associated with a service provided by the transmission frame. Also, the frame header may include a frame synchronization signal unit including synchronization signal information for extracting a start position of the transmission frame and a frame information unit including multiplexing information of data contained in the transmission frame. The multiplexing information denotes information associated with a transmission mode, a modulation level, a hierarchical modulation, and an error correction code of the data contained in the transmission frame.

    Abstract: A repeater converts a frequency of a received signal based on a local oscillating frequency and transmits a transmitting signal of a frequency that is different from the frequency of the received signal. Here, the local oscillating frequency includes a local oscillating error that may be different in a plurality of repeaters. Accordingly, the repeater cancels the local oscillating frequency error itself in a frequency conversion so that transmitting frequencies between the plurality of repeaters may be identical.
