TRANSMISSION METHOD OF DIGITAL BROADCAST SIGNALS SUPPORTING VARIOUS TRANSMISSION MODES IN THE DIGITAL SATELLITE BROADCASTING, A TRANSMISSION DEVICE, A RECEPTION METHOD, A RECEPTION DEVICE, AND A TRANSMISSION FRAME STRUCTURE 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.;COPYRIGHT KIPO 2013;[Reference numerals] (300) Transmission frame generator; (400) Transmission unit; (AA) First program providing unit; (BB,CC) Second program providing unit; (DD) First multiplexing unit; (EE) Second multiplexing unit; (FF) N-th multiplexing unit
