Error correcting decoder

An error correcting decoder for decoding a plurality of block units of data, said data being encoded with plurality of parameters, comprising:

• a plurality of error correcting decoding circuits for inputting and outputting said block units of data and for performing error-correction decoding for said block units of data on the basis of said plurality of parameters;
• a selection circuit for selecting one of said block units from an output of said plurality of error correcting decoding circuits on the basis of said encoding parameters of the selected block;
• a plurality of first memory devices for temporarily storing signals outputted from said plurality of error correction decoding circuits;
• a second memory device for storing said signals inputted to the error correction decoder based upon the order in which said signals are inputted;
• a reading device for reading said outputted signal in said plurality of first memory devices based upon said order in said second memory device;
• and
• a multiplexing circuit for outputting a multiplexed signal read out from said reading device.
