Abstract:
1. 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 and building one or two RS frames per a parade depending on RS frame mode information, the RS frame mode information indicating a single frame mode or a dual frame mode; mapping a portion of the one or two RS frames into a group, wherein the group further comprises known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data, wherein the FIC data includes status information of a mobile service, and wherein the TPC data includes FIC version information for identifying an update of the FIC data and the RS frame mode information; and transmitting a broadcast signal including the group, wherein the status information of the mobile service is assigned with two bits, and wherein a first bit indicates whether the mobile service is active or inactive and a second bit indicates whether the mobile service is hidden.
