Patent ID: 7647546

Claim:
A digital multimedia broadcasting (DMB) reception apparatus for receiving DMB service in a mobile communication system, the apparatus comprising: a Reed-Solomon (R-S) decoder for receiving a coded broadcast signal having a symbol and outputting an error symbol with a transport error indicator bit if all data bits in the symbol are ‘0’; and a moving picture experts group (MPEG) decoder for discarding the error symbol, wherein the R-S decoder comprises: an input buffer for storing input data on a symbol-by-symbol basis; a zero detector for outputting an error generated signal if all data bits in a symbol output from the input buffer are ‘0’; a transport error indicator bit generator for generating the transport error indicator bit according to the error generated signal output from the zero detector; an output symbol generator for generating an output symbol including the generated transport error indicator bit; and an error detector for detecting an error and a position of the error in a symbol output from the zero detector, if all data bits in the symbol output from the input buffer are not ‘0’, and determining whether to output an error generated signal or error correction signal, depending on whether a size of the detected error exceeds a threshold size.
