1. A method of operating a data processing system that comprises:
an encoder operable to compress data; and
a communication system operable to transfer data compressed by the encoder;
the method comprising:
the encoder compressing data to produce compressed data;
decompressing compressed data produced by the encoder to produce first decompressed data;
generating a first signature representative of the first decompressed data;
the communication system transferring compressed data produced by the encoder;
decompressing compressed data that has been transferred by the communication system to produce second decompressed data;
generating a second signature representative of the second decompressed data;
comparing the first signature and the second signature; and
using the comparison to determine whether an error has occurred.
