To transmit replacement commercial(CM) materials instead even when CM materials to be transmitted are non-recorded CM materials by preliminarily recording the replacement CM materials which may be interrupted at any time during the maximum CM material time length to be handled by a CM transmitting device, and which may be transmitted instead of CM materials in the CM transmitting device.

Commerical(CM) progress data 5 indicating the order of transmission of CM materials are preliminarily inputted to a video file control part 3. CM materials 6 are recorded in a video file part 4. Also, replacement CM materials are recorded in the video file part 4. When non-recorded CM materials are present in the CM materials recorded corresponding to the CM progress data 5, a video file control part 3 automatically transmits the replacement CM materials for the CM time length of the non-recorded CM materials inserted of the non-recorded CM materials. Thus, the materials which have no problem on operation can be transmitted, and impression to a viewer can be improved.
