Patent ID: 8161511

Claim:
A method of transmitting a broadcast signal in a transmitter, the method comprising: multiplexing mobile data and main data; and transmitting a transmission frame including the multiplexed mobile and main data, wherein a parade of data groups is transmitted during slots within the transmission frame, the slots being basic time periods for multiplexing of the mobile data and the main data, wherein the data groups include the mobile data, signaling information and known data sequences, wherein the signaling information includes fast information channel (FIC) data and transmission parameter channel (TPC) data, wherein the FIC data includes binding information between a service of the mobile data and an ensemble, and the TPC data indicates a version of the FIC data, wherein the FIC data includes an FIC data header and an FIC data payload having information identifying the ensemble, and the FIC data is divided into a plurality of FIC segments, and each of the plurality of FIC segments, including an FIC segment header and an FIC segment payload, is transmitted in each of the data groups, wherein the FIC segment header includes information indicating a number of a corresponding FIC segment and information indicating a number of a last FIC segment of the FIC data, wherein the ensemble includes the service and a signaling table describing the service, and wherein the ensemble is RS-CRC (Reed Solomon-cyclic redundancy check) encoded through a 2-dimensional Reed-Solomon (RS) frame, and each row of a payload of the RS frame includes a transport packet of the mobile data.
