Patent ID: 8171308

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 data 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 each of the data groups includes the mobile data, signaling information and regularly spaced known data sequences, wherein the signaling information includes fast information channel (FIC) data having binding information between a service of the mobile data and an ensemble and transmission parameter channel (TPC) data indicating a version of the FIC data, wherein the FIC data is divided into a plurality of FIC segments, and each of the FIC segments includes an FIC segment header and is transmitted in each of the data groups, wherein the FIC segment header includes an error indicator indicating whether or not an error is detected in a corresponding FIC segment, 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.
