Abstract
An information providing apparatus identifies a transmission enabled band of a transmission line and selects information conforming to the band, thereby effectively utilizing the transmission band of the transmission line. The apparatus determined a period which is to be required before demanded information is provided and notifies it to the user as a wait period, whereby the apparatus is made convenient for the user to operate. The apparatus is disconnected from the line during the wait period, thereby reducing a waste of a line charge.
