Abstract:
1. A method of transmitting a broadcast signal in a transmitter, the method comprising: encoding the mobile data for Forward Error Correction (FEC) to build a 2-dimensional Reed-Solomon (RS) frame through which the mobile data belonging to an ensemble is RS - cyclic redundancy check (RS-CRC) encoded, wherein the ensemble is a collection of services that require the same quality of service (QOS) and that are encoded with same FEC code, wherein the ensemble includes a service map table (SMT) describing a service and including an identifier of the ensemble and an identifier of the service; dividing the built RS frame into a plurality of portions; converting one of the plurality of portions to Serially Concatenated Convolutional Coding (SCCC) blocks according to an SCCC block mode; mapping the SCCC blocks to ten data blocks to form data groups that include the ten data blocks, wherein each of the data groups comprises a plurality of regions that include the ten data blocks, wherein the plurality of regions includes a first region having fourth, fifth, sixth and seventh data blocks, a second region having third and eighth data blocks, a third region having second and ninth data blocks and a fourth region having first and tenth data blocks, wherein the fourth, fifth, sixth and seventh data blocks are located between the third and eighth data blocks, wherein the third data block is located between the second and fourth data blocks, wherein the eighth data block is located between the seventh and ninth data blocks, wherein the second data block is located between the first and third data blocks, wherein the ninth data block is located between the eighth and tenth data blocks, and wherein the fourth data block includes fast information channel (FIC) data having cross layer information between a physical layer and an upper layer, and transmission parameter channel (TPC) data indicating a version of the FIC data and the SCCC block mode; forming mobile data packets including data in the data groups; multiplexing the mobile data packets and main data packets including main data; and transmitting a transmission frame including data in the multiplexed data packets, wherein a parade of the data groups is transmitted during slots in the transmission frame, the slots being basic time periods for multiplexing the mobile data and the main data.
