AUDIO CODER UTILISING REPEATED TRANSMISSION OF PACKET PORTION
摘要
A coder (13) generates a first output providing first data S1(n) from which a decoder can produce a reconstructed signal and a second output providing second, enhancement, data S2(n) 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 S1(n) in respect of a temporal portion n of the signal and the second data S2(n) in respect of the same portion of the signal and secondary data which includes the first data S1(n+1) in respect of a different temporal portion of the signal.
