Abstract:
1. A method for transmitting data over a channel, comprising: receiving data from a data source; generating categorization data that categorizes the data into one of a first category and a second category based on a determination of the degradation associated with reconstructing the data, the categorization assisting a receiver to reconstruct the data; transmitting at least a portion of the data and at least a portion of the, categorization data over the channel, wherein if the data is categorized into the firs category then error correction data is transmitted along with the data and the categorization data over the channel; receiving the data and categorization data; receiving the data and categorization data; determining whether the received data contains errors, if the data contains and is categorized in the first category then correcting the errors in the data by performing forward error correction based on the error correction data transmitted with the data; and if the data contains errors after performing the forward error correction, then further correcting the errors by performing error mitigation.
