The present invention concerns methods and devices for coding and decoding a coded data stream as well as a signal format for a coded data stream. The coded data stream includes at least one high-level data packet having partitions of data () requiring different protection rates. Partition detectors () are inserted between two such partitions by a partition detector inserter, in order to provide guidance for coding the partitions with different protection rates. Information about the code rates used for the different fields is extracted by a controller on the receiving side in order to decode the partitions with the right code rate.

Robust signal coding

In order to form argyle intarsia patterns, stacked arrays of selection levers cooperate with selection butts, the levers being capable of selecting the needles to be raised. Each array of selection levers is located symmetrically between two adjacent yarn feeding stations for cooperation with one or the other feeding station to select the desired needles depending upon the direction of machine reciprocating motion. The jack lifting and lowering profiles on the respective operative cam rings are symmetrical with respect to the feeding stations and to the arrays of selection levers. The jack lifting profiles include 'V' shaped notches in alignment with the selection levers, and, correspondingly, the intermediate-jack lowering profiles include 'V' shaped projections provided for further lowering the intermediate jacks.
