A method and an apparatus are provided for transmitting and receiving signaling information in a digital broadcasting system. First signaling information for a physical layer is encoded to generate a first coded block. Second signaling information is encoded to generate a second coded block. A frame including the first coded block, the second coded block and at least one physical layer pipe (PLP) data is transmitted. The first signaling information has a fixed number of bits. The second signaling information has a variable number of bits. The first signaling information includes information indicating a forward error correction (FEC) type of the second signaling information for receiving the second information. The second signaling information includes information indicating an FEC type used for a related PLP data.
