Claim:
The audio data code conversion and transmission method, comprising: a step of first audio code conversion and transmission means inputting compressed audio coded data, and outputting all or a part of frames of the input compressed audio coded data; a step of second to N-th (N is a predetermined integer equal to or larger than 2) audio code conversion and transmission means inputting the compressed audio coded data, decoding all or a part of the input compressed audio coded data, coding the decoded data, and outputting all or a part of frames of the coded data; a step of means transmitting output of the first to N-th audio code conversion and transmission means to first to M-th (M is a predetermined integer equal to or larger than 1) transmission lines; a step of selecting a transmission line for receiving the coded data from among first to M-th (M is a predetermined integer equal to 1 or larger) transmission lines; and a step of receiving the coded data from the selected transmission line, extracting the audio coded data received without a transmission error or a loss, and reconfiguring and outputting the audio coded data based on the extracted coded data.
