摘要： 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 apparatus 100 for inputting audio coded data includes first to N-th code conversion and transmission units 102 and 104 to 106 for converting audio data to N pieces of coded data, and transmitting the data at predetermined or adaptively variable time intervals to M transmission lines 130. The second to N-th audio code conversion and transmission units 104 to 106 codes a frame at a compression rate equal to or higher than the rate of input coded data. The code conversion and reception apparatus 120 selects a transmission line using a selection unit 107, and selecting data from correctly received coded data in a frame or packet unit, thereby reconfiguring the coded data using a coded data reconfiguration unit 112.

摘要： A transmission side has first through Nth moving picture encoder/senders (101-1 through 101-N) for compressing moving picture frames into N encoded data and sending the encoded data. Second through Nth moving picture encoder/senders (101-2 through 101-N) compress frames encoded by the first moving picture encoder/sender 101-1 at compression ratios which are higher than that of the first encoder/sender based on interframe prediction by referring to frames at the same time as the interframe prediction performed by the first moving picture encoder/sender. Each one of reception sides selects the encoded data having the lowest compression ratio and high image quality with frame-by-frame or packet-by-packet selection from the received encoded data without error and decodes the selected encoded data.
