FIELD: information technology.
SUBSTANCE: on a network the first and second transactions are switched on, separated by different visits of web-sites. At the first transaction the supplier of files gets payment through the network connection, chooses the first codec on the basis of the type of network connection and loads to the client the first copy of the media-file which is compressed by the first codec, guaranteeing loading of the additional copy of the song during the second transaction. During this second transaction this or another supplier loads an additional copy of the media-file without getting additional payment from the client. The additional copy is compressed by the second codec which is optimum for the connection used at the second transaction. Preferably clients make a decision to load files AAC+ of a smaller size on mobile stations, and the files AAC LTP with higher accuracy of reproduction - on a personal computer.
EFFECT: guaranteed loading of various types of hardware platforms with the allotment of media-files.
