Audio coder utilizing repeated transmission of packet portion |
摘要 |
A coder generates a first output providing first data from which a decoder can produce a reconstructed signal and a second output providing second, enhancement, data whereby a decoder receiving both the first and second data can produce a higher quality reconstructed signal. Packets of data are assembled for transmission, each packet containing primary data which includes the first data in respect of a temporal portion of the signal and the second data in respect of the same portion of the signal and secondary data which includes the first data in respect of a different temporal portion of the signal.
