ABSTRACT:
A system and a method of suppressing outstanding degradation of decoded audio quality due to a transmission error of audio coded data are provided without feedback information from a receiver, thereby reducing the increase of the number of necessary transmission bands and the arithmetic complexity on the receiving side. A code conversion and transmission apparatus100for inputting audio coded data includes first to N-th code conversion and transmission units102and104to106for converting audio data to N pieces of coded data, and transmitting the data at predetermined or adaptively variable time intervals to M transmission lines130. The second to N-th audio code conversion and transmission units104to106codes a frame at a compression rate equal to or higher than the rate of input coded data. The code conversion and reception apparatus120selects a transmission line using a selection unit107, and selecting data from correctly received coded data in a frame or packet unit, thereby reconfiguring the coded data using a coded data reconfiguration unit112.
