The invention, an electronic book selection and delivery system, is a new
way to distribute books and other textual information to bookstores,
libraries and consumers. The primary components of the system are a
subsystem for placing text in a video signal format and a subsystem for
receiving and selecting text that is placed in the video signal format.
The system configuration for consumer use contains additional components
and optional features that enhance the system, namely: (1) an operations
center, (2) a video distribution system, (3) a home subsystem, including
reception, selection, viewing, transacting and transmission capabilities,
and (4) a billing and collection system. The operations center and/or
video distribution points perform the functions of manipulation of text
data, security and coding of text, cataloging of books, messaging center,
and uplink functions. The electronic books may be provided to an
intermediate point such as a library or a bookstore. From the library or
bookstore, electronic books may be provided to consumers for viewing on
the home subsystem. The library may store electronic books for lending on
a file server. The library may incorporate security features to prevent
unauthorized copying of the electronic books, such as including a time
out feature that disables the electronic book after a specified period.
