Transmitting apparatus and transmitting method, receiving apparatus and receiving method, transceiver apparatus, communication apparatus and method, recording medium, and program

A receiving apparatus for receiving coded voice data obtained by coding voice data, comprising:

• receiving means for receiving the coded voice data;
• decoding means for decoding the coded voice data received by the receiving means;
• parameter storage means for storing a parameter concerning the reception performed by the receiving means and a parameter concerning the decoding performed by the decoding means in association with specifying information for specifying a transmitting side that transmits the coded voice data;
• and
• parameter setting means for selecting and setting, based on the specifying information, the parameter concerning the reception performed by the receiving means and the parameter concerning the decoding performed by the decoding means stored in the parameter storage means,
• wherein the receiving means further receives quality-improving data obtained by decoding the coded voice data and by improving the quality of decoded voice data, wherein the parameter storage means further stores the quality-improving data received by the receiving means in association with the specifying information.
