ABSTRACT:
A method of signal processing batch-bulk coded digital signals which are segmented into variable-length words and the variable-length words are allocated to constant-length blocks. The constant-length blocks which receive a variable-length word having a word length which is shorter than a predetermined word length are filled up with portions of variable-length words having a word length longer than the predetermined word length. Several successive constant-length blocks are combined into superblocks, and one address word which identifies the superblock location is added at one end of each superblock. The sum of the variable-length words within each superblock is smaller than, or equal to, the sum of the constant-length blocks within the superblock.
