Abstract
A terminal can play back song or video information in real time without downloading it, and thus restrictions on the hardware of the terminal are reduced and a large amount of music can be listened to anytime and anywhere. Also, the user can listen to music more cheaply than if it was downloaded, and copyright problems are reduced. Further, the terminal is charged based on the playback time or the amount of information. Accordingly, when the user stops playback because he or she does not like a song, the price is less than it is when the user listens to the song to the end, and thus the user can feel free to use this service.
