FIELD: information technology.
SUBSTANCE: invention relates to data transfer, more specifically to reformatting variable-rate vocoder frames for system transmission. Method and apparatus are presented for supporting transmission of variable-rate vocoder frames over non-compatible communication channels. Variable-rate vocoder frames are reformatted as effective load in multi-rate vocoder frames. At the receiver determination is made as to whether a received multi-rate vocoder frame carries a variable-rate vocoder frame effective load. If a variable-rate vocoder frame is effective load, then determination of the frame type is made. Various versions for conveying effective load information are presented.
EFFECT: possibility of transmitting through non-compatible systems variable-rate vocoder frames without their conversion into fixed-rate or multi-rate vocoder formats.
