Abstract: There are provided a content data transmission method, device, and program that minimize serious disturbances in reproduced content on the reception side, caused by a transmission error of encoded data, without sending feedback information from the reception side to the transmission side. When an encoder creates encoded data to be distributed, the encoder creates plural items of encoded data at the same time or creates FEC data at the same time in advance and, when storing the data in a file, stores the data as if the data were one item of encoded data. When a distribution server distributes the data using the file, the plurality of items of encoded data are automatically distributed at the same time and the FEC data is distributed. A client receives the plurality of items of encoded data or the FEC data to reduce the probability of data shortage due to a packet loss and, as a result, the deterioration in the image quality and the audio quality is reduced.

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 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.
