A method of generating a bit stream by multiplexing non-compressed auxiliary information with an information stream. The information stream is obtained by compressing fixed-size units of an information signal with a varying compression ratio to provide varying-sized units of the information stream. The auxiliary information is for use in subsequently processing the information stream. Units of the auxiliary information correspond to the units of the information signal. In the method, the information stream is divided in time into information stream portions. The non-compressed auxiliary information is also divided in time into auxiliary information portions. The information stream portions and the auxiliary information portions are interleaved to provide the bit stream. Finally, the information stream dividing, auxiliary information dividing, and interleaving steps are controlled by emulating decoding of the bit stream by a hypothetical system target decoder. The hypothetical system target decoder includes a demultiplexer that demultiplexes the bit stream, a serial arrangement of an information stream buffer and an information stream decoder, and a serial arrangement of an auxiliary information buffer and an auxiliary information processor. Each serial arrangement is connected to the demultiplexer. The information stream dividing, auxiliary information dividing, and interleaving steps are controlled such that the information stream buffer and the auxiliary information buffer neither overflow nor underflow.
