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

摘要

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.
