1. A method of compression encoding an input data set into variable compression ratio, variable length data packets, the method comprising:

  • receiving a data set;

    dividing the data set into fixed length data packets;

    determining whether the fixed length data packets are analog fixed length data packets;

    converting, if the fixed length data packets are determined to be analog fixed length data packets, the analog fixed length data packets to digital fixed length data packets;

    determining the density of each fixed length data packet;

    compressing each fixed length data packet to produce variable compression ratio, fixed length data packets, using a compression ratio determined by the density of each fixed length data packet;

    determining the number of valid data bytes in each variable compression ratio, fixed length data packet;

    removing any invalid data bytes from each variable compression ratio, fixed length data packet;

    adjusting the fixed length of each variable compression ratio, fixed length data packet to produce a variable compression ratio, variable length data packet that contains only valid data bytes;

    inserting at least data packet length information in each variable compression ratio, variable length data packet; and

    outputting the variable compression ratio, variable length data packets.
