Abstract:
1. A method for processing a broadcast signal in a broadcast transmitter, the method comprising: randomizing mobile service data; Reed Solomon (RS)-cyclic redundancy check (CRC) encoding the randomized mobile service data to build an RS frame; first converting the RS-CRC encoded mobile service data into a bit unit of data; error correction encoding the first converted mobile service data using a coding rate of G/H, wherein G and H are integers and wherein H is greater than G; second converting the error correction encoded mobile service data into a byte unit of data; formatting data groups including the second converted mobile service data; multiplexing mobile service data packets including the mobile service data in the data groups with main service data packets including main service data; non-systematic RS encoding the mobile service data in the mobile service data packets and systematic RS encoding the main service data in the main service data packets; and transmitting a broadcast signal including a transmission identifier of a collection of data groups being included in slots, each slot being a time period for multiplexing mobile service data and main service data.
