Abstract (en)

[origin: EP3023984A1] Disclosed are an encoder and encoding method for a multi-channel signal, and a decoder and decoding method for a multi-channel signal. The present invention may code a normal channel signal and a low-frequency effects (LFE) channel signal included in a multi-channel signal through a two-stage coding process or a one-stage coding process employing a time delay, thereby efficiently coding a multi-channel signal.
