TRANSMISSION METHOD, TRANSMISSION APPARATUS, RECEPTION METHOD, RECEPTION APPARATUS OF DIGITAL BROADCASTING SIGNAL AND TRANSMISSION FRAME-FORM THEREOF |
摘要 |
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. |
