A transmission system for transmitting compressed audio data selected by a user from compressed audio data stored in a server to a client located remote from the server. If the state of the recording medium loaded on the client side is normal and/or the money deposited on the client side is sufficient to permit charging the user, the selected compressed audio data starts to be transmitted from the server. If the state of the recording medium loaded on the client side is not normal and/or the money deposited on the client side is insufficient to permit charging the user, transmission of the selected compressed audio data from the server is inhibited. This prevents incorrectly billing the client.
