1. A method of coding a source signal representing a moving picture, comprising the steps of:

  • (a) generating a series of digital information items of at least three different types from said source signal, said different types of digital information item indicating information about the moving picture;

    (b) coding the digital information items of at least one of said types according to at least one fixed-length coding rule, thereby generating fixed-length codewords; and

    (c) coding the digital information items of all other of said types, comprising at least two of said types, according to a single, self-resynchronizing, variable-length coding rule, thereby generating variable-length codewords.
