Then, at block 350, the media relay server determines if at least one frame read from the file of the replacement advertisement is in the desired format. If the result of the determination is that at least one frame is not the desired type, then the process branches to block 340 to read another at least one frame from the file of the replacement advertisement, If this is the desired form, the process proceeds to block 360.

At block 360, the media relay server determines if at least one frame above is sufficient. If the result of the determination is that at least one frame is not sufficient, the process branches to block 340 to read another at least one frame from the file of the replacement advertisement. On the other hand, if the result of the judgment is that at least one frame is sufficient, the process branches to block 330. In the block 330, the media relay server reads the corresponding frame from the buffer section, In the block, the media relay server inserts the corresponding frame of the substitute advertisement read from the buffer unit at the substitute advertisement inserting position of the media file, thereby combining it with the media file. The combined media files may also be provided to the user device 130, for example, where a media player capable of running the media file through the network 120 of FIG. 1 is provided.
