Abstract
A receiver is arranged to start receiving a data frameincluding application data followed by parity data. An erasure information table is generated, and includes one element for each element of a data frame. If there are no errors in the application data, the receiver is powered-down to sleep without receiving the parity data, and the application data is used without correction being needed. If the number of errors in the application and parity data exceeds the MPE-FEC correction capability, the receiver is powered-down to sleep without further parity data being received and the data is not decoded. If the number of errors is smaller than the MPE-FEC correction capability, the receiver is powered-down to sleep when sufficient parity data is received to correct errors in the application and parity data. This can save power in the receiver. In another embodiment, the erasure information table includes one element for each column of a data frame.
