Patent ID: 8850493

Claim:
A method of processing broadcast data in a broadcast transmitter, the method comprising: performing, by a Reed Solomon (RS) encoder, RS encoding and Cyclic Redundancy Check (CRC) encoding on mobile service data to build RS frames belonging to an ensemble, wherein each of the RS frames is mapped into data groups that comprise known data sequences and a portion of fast information channel (FIC) data including information for rapid mobile service acquisition, wherein the information for rapid mobile service acquisition includes transport stream identification information for identifying a mobile broadcast carrying a mobile service that includes the mobile service data and current and next (C/N) indication information for indicating whether the FIC data are applicable to a current transmission frame or a next transmission frame; multiplexing data in the data groups and main service data; and transmitting a transmission frame including the multiplexed data in the data groups and the main service data, wherein the transmission frame comprises sub-frames that comprise slots that are time periods for multiplexing the mobile service data and the main service data, wherein each of the data groups is transmitted during each of the slots, wherein transmission parameters are transmitted in each slot during which each data group is transmitted, and wherein the transmission parameters comprise information for indicating a sub-frame number that contains the slot and information for indicating a total number of data groups to be transmitted during one sub-frame of the transmission frame.
