FIELD: information technology. ^ SUBSTANCE: signal processing method involves receiving at least one of a first and second signal, receiving mode information to indicate that the assigned mode corresponds to one of at least three modes including a first mode, a second mode and a third mode, and if mode information indicates that the assigned mode is a first mode, then decoding the first signal using a first encoding scheme, if the mode information indicates that the assigned mode is a second mode, decoding the first signal and the second signal, including: decoding the first signal using a first encoding scheme, decoding the second signal using a second encoding scheme, generating the output signal using the decoded first signal and the decoded second signal, if mode information indicates that the assigned mode is a third mode, then decoding the second signal using a second encoding scheme, wherein the first encoding scheme corresponds to a voice encoding scheme, and the second encoding scheme corresponds to an audio encoding scheme. ^ EFFECT: high efficiency of processing different signals owing to selection of the optimum encoding scheme. ^ 11 cl, 9 dwg |
