    摘要： A method for transmitting signaling information includes: generating a link layer packet including signaling information; and transmitting the generated link layer packet. The link layer packet includes a fixed header and a payload. The signaling information includes information regarding a broadcast program and data and information needed for reception of the broadcast program and data, and the signaling information is contained in the payload of the link layer packet. The fixed header includes a packet type element for identifying a category of data contained in the payload of the link layer packet and a signaling type element for identifying a format of the signaling information contained in the payload of the link layer packet.
