发明名称 Broadcasting signal transmission device, broadcasting signal reception device, and method for transmitting/receiving broadcasting signal using same
摘要 Disclosed is a broadcasting signal transmission device, a broadcasting signal reception device, and a method for transmitting/receiving a broadcasting signal using same. The method for receiving the broadcasting signal comprises the following steps: receiving the broadcasting signal, which includes a transmission frame, wherein the transmission frame includes a plurality of PLPs, which transmit components that constitute a broadcasting service, first signaling information and second signaling information, which include the signaling information of the plurality of PLPs, a first preamble signal, which has been signaled with a preamble format, and a second preamble signal, which has been signaled with pilot pattern information, wherein one of the plurality of PLPs is a base PLP, which includes a program number that corresponds to the broadcasting service and program map table information, which has been signaled with identifying information for each of the PLPs; demodulating the broadcasting signal based on the first and the second preamble signals; FEC decoding the demodulated broadcasting signal; and identifying a PLP group that includes the plurality of PLP from the FEC decoded broadcasting signal based on the first and the second signaling information, decoding at least one PLP of the identified PLP group, and providing the broadcasting service.

主权项 1. A method for receiving broadcast signals, the method comprising: receiving the broadcast signals; demodulating the received broadcast signals by an OFDM (Orthogonal Frequency Division Multiplex) scheme; parsing at least one signal frame from the demodulated broadcast signals, wherein each signal frame includes a preamble and a plurality of PLPs (Physical Layer Pipes), wherein the preamble located at the beginning of the each signaling frame includes signaling information for each PLP, and wherein each PLP carries at least one broadcast service or at least one broadcast service component and a randomly chosen PLP of the plurality of PLPs is a base PLP; decoding the signaling information, wherein the signaling information includes PLP ID information for identifying each PLP and PLP GROUP information for identifying a PLP group related to corresponding PLPs; and decoding data carried in each PLP in the parsed at least one signal frame based on the decoded signaling information, wherein the base PLP carries service signaling data for corresponding PLPs, and wherein the signaling information includes identification information for identifying the randomly chosen PLP.
