`ABSTRACT
`
`An electronic publication publishing and distribution system
`is provided for dissemination of written materials that can be
`read on a portable electronic book. Ahost computer contains
`an inventory of written materials in electronic form, that can
`be selected and then downloaded into the portable electronic
`book’s memory. The host computer keeps track of the
`transactions, and encodes the data prior to downloading,
`using an encryption system involving a security number that
`is unique to the portable electronic book. The encrypted data
`cannot be decrypted until it is resident in the memory of the
`portable electronic book. Upon receipt of the encrypted data,
`the portable electronic book decrypts the data, and can
`display the text of the original material on its display screen.
`The portable electronic book has a central processing unit
`with an operating system for controlling the functions of the
`portable electronic book. There is non-volatile electronic
`memory storage for retaining publications in the portable
`electronic book. Aplurality of electronic keys is provided in
`the portable electronic book that corresponds to graphical
`representations such as icons on the portable electronic book
`display adjacent to each key. These keys are integral to the
`user interface for controlling the devices.

`METHOD AND APPARATUS FOR VIEWING
`ELECTRONIC READING MATERIALS
`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`
`The present invention relates generally to the publication
`and distribution of electronic reading materials, and to a
`method and apparatus for viewing electronic reading mate-
`rials.
`
`2. Description of the Related Art
`Electronic reading materials are commonly available on
`various on-line computer services, such as America On Line,
`Compuserve, the Internet and the World Wide Web. These
`materials are typically in the public domain, as there is no
`accepted method for distribution that maintains the integrity
`of copyrighted materials. This is due in part to the ease with
`which the recipient of the documents can redistribute them
`at no cost to potentially thousands of other subscribers, with
`no accounting for the royalties that are due to the copyright
`holder.
`
`Although it is a simple process for on-line subscribers to
`download these materials to their computer using a tele-
`phone line modem or other communication system, it is not
`practical for multiple-page documents to be read while
`sitting at a computer terminal.
`Accordingly,
`there is a need in the technology for a
`system for retaining a library of publications and for selec-
`tively loading these publications into a portable viewer with
`non-volatile memory storage. There is also a need in the
`technology for providing a secure communications system
`that permits downloading of copyrighted materials without
`concern for their proliferation through present on-line ser-
`v1ces.
`
`SUMMARY OF THE INVENTION
`
`The present invention is directed to a system for retaining
`a library of publications and for selectively loading these
`publications into a remote portable electronic viewing unit
`with non-volatile memory storage. The present invention
`also provides for a secure communications system that
`permits downloading of copyrighted materials without con-
`cern for their proliferation through present on-line services.
`One embodiment of the present invention includes an
`electronic publication and distribution system having a host
`computer which communicates with a plurality of remote,
`portable electronic viewing units, such as portable electronic
`books. The portable electronic books are designed to be able
`to load publications, selected from a bookstore or other
`on-line source via the host computer, into the remote com-
`puter memory. Each portable electronic book has a modem
`or other communications part for receiving and transferring
`data between the host and the portable electronic book. The
`portable electronic book has a central processing unit with
`an operating system for controlling the functions of the
`portable electronic book. There is non-volatile electronic
`memory storage for retaining publications in the portable
`electronic book. A plurality of electronic switches are pro-
`vided in the portable electronic book that correspond to
`graphical representations such as icons on the portable
`electronic book display adjacent
`to each switch. These
`switches are integral to the user interface for controlling the
`devices. A digitized pen input system can also be provided
`for the user interface.
`
`Accordingly, an object of the invention is to provide an
`improved publication distribution system and a method of

`storing publications and for loading a selected program or
`set of publications into an electronic display device.
`Another object of the invention is to provide a method of
`maintaining a publication “virtual bookstore” that allows for
`an effective manner of examining the contents according to
`individual interests, and selecting the material to download.
`A further object of the invention is to provide a portable
`electronic viewing unit that is compatible with the virtual
`bookstore, and the corresponding security and communica-
`tion features.
`
`A further object of the invention is to provide a user
`interface in the portable viewer that facilitates the selection,
`navigation and manipulation of the published works as they
`are read.

`
`DETAILED DESCRIPTION OF THE
`PREFERRED EMBODIMENT
`
`the terms electronic
`In the following description,
`publications, reading materials, text and documents are used
`interchangeably and generally refer to reading materials,
`pictures and graphics that can be read by literate individuals.
`The features: remote viewing system, portable viewer, elec-
`tronic book and display device, refer to a system for viewing
`reading materials. The terms: user interface, navigation,
`control and manipulation, refer to methods for controlling
`the environment of the reading materials. Typical applica-
`tions are reading materials that are of such a time-sensitive
`nature that publication and distribution via conventional
`means is not practical. Other applications include materials
`that consist of a collection of texts from a plurality of
`sources which are compiled in such a way as to provide
`value to the reader, materials currently out of print, and
`materials of highly specialized interest, limited interest or of
`unknown interest so as to not justify publication in printed
`form.

`Referring now to FIG. 1, the publication and distribution
`system 10 of the present invention includes transmitting
`station 12 and receiving station 14. The transmitting station
`12 includes host computer 16, content database 18, data
`compressor 20, data encryptor 24, modem 26 and memory
`40. The receiving station 14 includes modem 30, which is
`connected to a portable display unit 32 and optionally, a
`personal computing device 44. It should be understood that,
`although the data communication between the computer 16
`and the computer 44 or device 32 is described as unidirec-
`tional (from the computer 16 to the computer 44 or device
`32), the system 10 allows for bi-directional communication.
`In addition, one of ordinary skill in the art will recognize that
`either one side or both sides of the system 10 can be
`embodied as a transmitter/receiver. The publication and
`distribution system 10 is controlled by a host computer 16
`located within the transmitting station 12. The host computer
`16 can be any computer, data processing system, or World
`Wide Website capable of handling the peripheral devices
`described below.
`
`The host computer 16 manages a content database 18
`which contains primarily copyrighted publications or works.
`In the process of distributing these works, the host computer
`16 communicates with a portable display unit 32 located
`within the receiving station 14. The receiving station 14
`includes modem 30, which is connected to a portable display
`unit 32 through a communications channel 34, which may be
`a digital data stream on a telephone line, an Integrated
`Services Digital Network (ISDN) line, a coaxial cable, a
`fiber optic cable or any other serial streaming medium.
`As shown in FIG. 1,
`the communications channel 34
`includes data compressor 20, data encryptor 24 and modem
`26 which are located at the transmitting station 12, and
`modem 30, and optionally, a personal computing device 44
`and portable display units which are located in the receiving
`station 14. The host computer 16 first
`interrogates the
`portable display unit 32 through the data channel 34 for its
`unique serial number, which consists of a number that serves
`as a “public key” 36 in the data encryption system. The host
`computer 16 compares the public key 36 against a valid key
`list 42 located in memory 40 to determine whether it is a
`valid key. If it is,
`the host computer 16 passes the data
`through the data compressor 20, which may be a software
`algorithm, hardware device, or combination of the two. The
`host computer 16 then uses this key 36 to encrypt
`the
`selected published works from the content database 18 using
`a corresponding private key from the key list 42, and a data
`encryptor 24, which may be a software algorithm, hardware
`device, or combination of the two, as is known in the
`technology.
`The encrypted, compressed data is then sent to the display
`device 32 through a modem 26 located at the transmitting
`end of the system 12. The modem 26 modulates the data
`according to the requirements of a transmission medium 28,
`which may be a landline, a satellite, a cable, a fiber or other
`telecommunications medium. At the receiving end, a modem
`30 demodulates the data provided in a transmission medium
`28. The modem 28 can then provide this data to the portable
`display unit 32, or alternatively, to a personal computing
`device 44, which then provides the data to the display device
`32 through an electronic connection 46.
`Once the data is in the portable display unit 32, the data
`is decrypted using the private key 38 of the device 32. This
`is accomplished either through a software algorithm, a
`hardware device, or combination of the two, as is known in
`the technology. The resulting compressed data is then stored
`in non-volatile memory in the portable display unit 32.
`

`FIG. 2A is one embodiment of the portable display unit 32
`of the present invention, as utilized in the publication and
`distribution system 10 of FIG. 1. The portable display unit
`32 a slim rectangular unit of six inches in width, seven
`inches in height and one inch thick. The portable display unit
`has a front face 50, a top 52, a base 54, a first side 55, a
`second side 56 and a back 58. The front face 50 includes a
`display screen 60, which may be a liquid crystal display
`(LCD), cathode ray tube (CRT), electro-luminescent display
`(EL) or other display device as is known in the technology.
`In a preferred embodiment, the display screen 60 is an LCD.
`Located next to the display screen 60, along the second side
`56, are a plurality of keys or function switches 62, which are
`used to select icons displayed on the display screen 60.
`These icons represent a variety of functions that are pro-
`vided by the portable display unit 32, as will be discussed in
`detail in the following sections. The brightness of the display
`screen 60 is controlled by an LCD adjust switch 64 located
`below the display screen 60, at the bottom of the front face
`50.
`
`Located on the top 52 of the portable display unit 32 is a
`switch 66 for powering the portable display unit 32 on or off.
`In addition, an RJ-11 phone jack 68 is located on the top 52,
`as is a connector 70 for connection to an AC adapter 72. The
`phone jack 68 and connector 70 may alternatively be located
`on the back 58 of the portable display unit 32. In addition,
`the portable display unit 32 may be powered by batteries
`such as NiMh batteries. The portable display unit 32 also
`includes an electronics module (not shown), which includes
`a central processing unit (CPU), memory units such as
`Read-Only Memory (ROM), Random Access Memory
`(RAM) and non-volatile Random Access Memory
`(NVRAM), an internal modem, the LCD driver, a charge
`circuit and a clock, and optionally,
