ABSTRACT:
An arithmetic datastream representative of an original sequence of input bi-level symbols is transmitted, before an information code carrying information on a total length of the input symbols, from a coding subsystem to a decoding subsystem. A register shifts out respective transmitted portions of the datastream to an arithmetic decoder, where they are decoded into a symbol sequence starting with the same sequence as the original sequence. The decoded symbol sequence is output through an output circuit which counts symbols in that sequence. The register holds a final portion of the datastream. The information code is decoded by an information decoder, which informs the output circuit of decoded information, before flushing the register to input the final portion of the datastream to the arithmetic decoder. The output symbol sequence becomes equal in symbol number to the original sequence, when the output circuit stops outputting.
