摘要：
The invention, an electronic book selection and delivery system (200), distributes text to subscribers (258). The system includes a subsystem for placing text in a video signal format (204) and a subsystem for receiving and selecting video format text (216). The system contains an operation center (250), a video distribution system (208), a home subsystem (258), and a billing and collection system. The operation center (250) and/or video distribution points (1020) perform the functions of manipulation of text data, security and coding of text, cataloging of books, message center, and uplink functions. The home subsystem (258) connects to a video distribution system (208), generates menus and stores text, and transacts through communicating mechanisms (611, 613, 617). A portable book-shaped viewing device (266) is used for viewing the text. The billing system (278) performs the transaction, management, authorization, collection and payments utilizing the telephone system (274).
