Abstract:
1. A signal decoding apparatus that decodes coded information formed with n layers, n being an integer of two or greater, the signal decoding apparatus comprising: a coded information operation section that performs error detection for the coded information per layer; a decoding section that, when no error is detected in m layers, m being an integer of one or greater and n or less, decodes coded information of the m layers, per layer, and generates m decoded signals, and that, when a frame is lost in an i-th layer, i being an integer of two or greater and n or less, decodes coded information of a first to (i−1)-th layers, per layer, and generates (i−1) decoded signals; a sampling frequency adjustment section that adjusts sampling frequencies of all decoded signals generated, to sampling frequencies in accordance with transmission mode employed upon transmission; and an addition section that adds all the decoded signals with adjusted sampling frequencies.
