A controller for obtaining a contents list via a network, in which a contents list of scroll destination is quickly obtained when a scroll instruction is input, is provided. When the scroll instruction in the contents list is input by a user's operation, the controller sets a scroll list obtaining flag into an on state, and preferentially obtains contents information about the scroll destination. When the scroll list obtaining flag is set into the on state, the controller does not transmit a normal contents list obtaining request to a contents list transmitting apparatus. Since the controller transmits the normal contents list obtaining request after average response time passes, the controller can obtain the contents information about scroll destination in the contents list without delay.
