Patent ID: 8370728

Claim:
A receiving system comprising: a signal receiving unit for receiving at least first mobile service data or second mobile service data; a first data processor for demodulating the received first mobile service data and performing first error correction decoding on a Reed-Solomon (RS) frame that includes the demodulated first mobile service data in order to correct an error generated in the first mobile service data, wherein the RS frame includes at least one data packet that includes the demodulated first mobile service data, RS parity data generated based on the at least one data packet, and Cyclic Redundancy Check (CRC) checksum data generated based on the at least one data packet and the RS parity data; a second data processor for demodulating the received second mobile service data and performing second error correction decoding different than the first error correction decoding on the demodulated second mobile service data in order to correct an error generated in the second mobile service data; and an Audio/Video (A/V) decoder for performing AV decoding on at least the error-corrected first mobile service data or the error-corrected second mobile service data.
