FIELD: data processing.
SUBSTANCE: invention relates to the transmission of redundant frame information. Frame decoding method comprises: receiving a second audio frame at a decoder of a computing device, wherein the second audio frame follows a first audio frame in an audio signal, the second audio frame includes: a first number of bits allocated to primary coding information associated with the second audio frame; a second number of bits allocated to redundant coding information associated with the first audio frame; and an indicator of whether the first audio frame has an all-predictive frame type, a noise-excited linear prediction frame type, a generic frame type, a non-predictive frame type, or a frame type that does not carry redundant coding information. In response to the frame erase state associated with the first audio frame, determining, based on the indicator, the second number of bits of the second audio frame that are allocated redundant coding information associated with the first audio frame; and decoding the first audio frame based on the redundant coding information.
EFFECT: technical result of the invention is improved efficiency of encoding / decoding data.
