Patent ID: 8089929

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 the mobile data and the main data, wherein data groups of multiple parades are assigned to a single transmission frame and a plurality of consecutive data groups are assigned to be spaced apart from one another within the transmission frame, wherein each of the data groups includes the mobile data, signaling information and 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, wherein each of the plurality of FIC segments includes an FIC segment header and is transmitted in each of the data groups, wherein the ensemble includes the service and a signaling table describing the service, and wherein the mobile data belonging to the ensemble is RS-CRC (Reed Solomon-cyclic redundancy check) encoded through a 2-dimensional Reed-Solomon (RS) frame, each row of a payload of the RS frame including a transport packet of the mobile data.
