Abstract:
1. A broadcast signal transmitting method, the method comprising: encoding each of PLP (Physical_Layer_Pipe) data and first signaling information, the PLP data including a base layer and an enhancement layer of a broadcast service; generating a preamble including the encoded first signaling information and a transmission frame including a plurality of LLPs (Link_Layer_Pipes), wherein each of the plurality of LLPs includes the encoded PLP data, second signaling information, and third signaling information, wherein the first signaling information includes a first identifier identifying each of the PLP data and a second identifier identifying each of the plurality of LLPs, wherein the second signaling information includes a first descriptor including the first identifier and the second identifier, and wherein the third signaling information includes a second descriptor including information on the base layer and enhancement layer of the broadcast service, and a third descriptor including information on whether each component being transmitted through the PLP data corresponds to the base layer or the enhancement layer; and transmitting a broadcast signal including the transmission frame.
