FIELD: communications engineering. SUBSTANCE: proposed method is used for transmitting plurality of variable-speed dataflows. Plurality of dataflows is jointly multiplexed into common data frame. Information is channel-coded and multiplexed jointly with certain number of service bits containing coded information into multiplexed frame. The latter is then demultiplexed in at least one channel frame each being transmitted over separate channel such that first code channel always includes data on service bits. EFFECT: ability of transmitting plurality of variable-speed dataflows. 27 cl, 5 dwg
