Abstract:
A method of receiving and decoding coded data in a system having a transmission layer and a coding layer, the coded data being divided into transmission units, each transmission unit being received separately in the transmission layer, errors being detected in each transmission unit in the transmission layer, the received data being converted to coding units in the transmission layer, the coding units having a definite relation to the transmission units, the coding units being provided to the coding layer, each coding unit being decoded separately in the coding layer, comprising the steps of:providing error information from the transmission layer to the coding layer, said error information reporting results of error detection performed in the transmission layer by indicating which of the coding units provided from the transmission layer to the coding layer are free of errors; and using said error information, when information repeated in different coding units has different values in the different coding units, to select a correct value from among said different values.
