ABSTRACT:
A TV music broadcasting program is distributed from a distribution apparatus through a ground station and a satellite, and a musical-piece program is also distributed through a plurality of audio channels. A subscriber looks for the desired musical piece from a musical-piece list displayed on the screen of a TV receiver and downloads it into a storage device. A pay-per-view method is employed in which accounting is performed in units of musical pieces. At downloading, a purchase record is stored in an IC card placed in a receiving apparatus and it is periodically sent to a customer management center. The customer management center calculates the viewing fee and issues a bill to the subscriber. A copyright management apparatus in the distribution apparatus obtains the purchase record of a musical piece from the customer management center to calculate a copyright fee to be paid to the copyright holder.
