Definitions

  • Fig. 5 illustrates an encoding procedure according to the invention for the intermediate data stream 208 comprising the intermediate data units IF1, IF2, IF3... from the previous decoding operation 204.
  • the intermediate data is received and may be arranged into new intermediate data segments SI, S2 , S3... 500, if necessary, to be encoded into the second format F' .
  • the size of the new intermediate data segments 500 is in this example different from the size of the intermediate data units 300 coming from the decoding operation 204.
  • Each new intermediate data segment or unit 500 is then encoded 206 into a new data unit 506 of the second format F' based on a current encoding state ES 502 extracted from a previous encoding operation.
  • An encoding state comprises variables or parameters, apart from the actual data, extracted from the performed encoding operation and which is used for encoding data.
