Abstract
A digital multimedia broadcasting (DMB) reception apparatus receives DMB service in a mobile communication system. In the DMB reception apparatus, a Reed-Solomon (R-S) decoder receives a coded broadcast signal and outputs an error symbol with a transport error indicator bit, if all data bits in the symbol are ‘0’. A moving picture experts group (MPEG) decoder discards the error symbol.
Claims19
A reception apparatus in a mobile communication system, the apparatus comprising:
- a Reed-Solomon (R-S) decoder for receiving a coded broadcast signal;
- 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.
A decoding apparatus for decoding a coded symbol in a mobile communication system, the apparatus comprising:
- 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 a transport error indicator bit according to the error generated signal output from the zero detector;
- and
- an output symbol generator for generating an output symbol comprising the generated transport error indicator bit.
A method for receiving digital multimedia broadcasting (DMB) service in a mobile communication system, the method comprising the steps of:
- receiving a broadcast signal;
- outputting an error symbol including a transport error indicator bit if all data bits in the symbol are ‘0’;
- and
- discarding the error symbol.
A method for decoding a coded symbol in a mobile communication system, the method comprising the steps of:
- storing input data on a symbol-by-symbol basis;
- outputting an error generated signal if all data bits in an input symbol are ‘0’;
- generating a transport error indicator bit according to the error generated signal;
- and
- generating an output symbol comprising the generated transport error indicator bit.
