Abstract:
1. A method of receiving a broadcast signal in a receiver, the method comprising: receiving a broadcast signal including a transmission frame, wherein a parade of data groups in the broadcast signal is received during slots within the transmission frame, the slots being basic time periods for multiplexing of mobile data and main data, and each of the data groups includes the mobile data, signaling information and known data sequences; demodulating the broadcast signal and obtaining, from the signaling information, fast information channel (FIC) data having cross layer information between a physical layer and an upper layer, and transmission parameter channel (TPC) data having an identifier of the parade and version information of the FIC data; building a Reed-Solomon (RS) frame corresponding to an ensemble of a service of the mobile data by: extracting video data from the mobile data; parsing the extracted video data by a network abstraction layer (NAL) unit; and decoding the parsed video data based on header information of the parsed NAL unit.
