1. A system (FIG. 12) for processing a packetized digital datastream (MPEG Byte Data In) to produce an output datastream (Symbol Data Out) representing sequential datafield structures each containing data and overhead information, said system comprising:

  • input means (14, 24,

         30) for providing a datastream of data packets separated by inter-packet data gaps;

    means (48) for providing a field overhead information segment (Field Sync) having a duration different than the duration of inter-packet gaps within a data field; and

    processing means (16,

         50) responsive to said datastream from said input means and to said field overhead segment for producing an output datastream (Symbol Data Out) representing a sequence of datafield structures (FIG.

         1) each comprising a field overhead segment and a data field containing a group of data segments (X);

    whereinsaid input means provides said datastream with predetermined constant uniform inter-packet gaps over a plurality of said datafield structures, said uniform inter-packet gaps being dimensioned to facilitate the insertion of overhead information.
