Patent ID: 8046794

Claim:
A method for receiving a broadcast signal, the method comprising: receiving a broadcast signal including a transmission identifier of a collection of mobile service data groups being included in slots, each slot being a time period for multiplexing mobile service data and main data, wherein the mobile service data is processed using a process comprising: Reed Solomon (RS)—cyclic redundancy check (CRC) encoding the mobile service data, converting the RS-CRC encoded mobile service data into a bit unit of data to generate first converted mobile service data, 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, converting the RS-CRC encoded mobile service data into a byte unit of data to generate second converted mobile service data, and non-systematic RS encoding the second converted mobile service data, and wherein the main data is encoded by systematic RS encoding; demodulating the broadcast signal; acquiring the transmission identifier from the broadcast signal; and receiving the collection of mobile service data groups corresponding to the transmission identifier by cyclically supplying power to a tuner, wherein the broadcast signal has a plurality of types of known data sequences.
