发明名称 Music distribution system and associated antipiracy protections
摘要 Music is blanket transmitted (for example, via satellite downlink transmission) to each customer's computer-based user station. Customers preselect from a list of available music in advance using an interactive screen selector, and pay only for music that they choose to have recorded for unlimited playback, for example, by a “CD burner”. An “ID tag” is woven into the recorded music so that any illegal copies therefrom may be traced to the purchase transaction.
