  Inspired by the information superhighway concept, a revolution will occur in the distribution of books. Since the invention of movable typeset printing by Gutenberg, the world has never been at the root of such a revolution in the distribution of text materials. The definition of the term “book” will change dramatically in the near future.

  For reasons such as security, convenience, cost, and other technical issues, book and magazine publishers can currently distribute their products only in paper form. However, the present invention solves the problems facing publishers.

  Electronic book selection and transport systems are a new way of distributing books to bookstores, libraries, schools and consumers. The technical breakthrough of the present invention provides a reliable electronic system for delivering selected electronic books and receiving payment. This system provides consumers with everyday, familiar devices that are highly practical, portable, and easy to use while at the same time having a high technical appeal.

  The effect of this system is that the distribution of physical objects such as paper books and computer memory devices has been removed from the book or text distribution system. The purchase of books becomes a pay-per-read TM and avoids the overhead, "middle man", printing costs, and time delays associated with current book distribution systems. Published materials and text, such as presidential speeches, new legislation, court decisions on abortion, OJ Simpson's testimony, etc., can be made immediately available to consumers at minimal cost. In addition, when the advertising company that sponsors the book and embeds the advertisement in the book bears the funds, the book can be used free of charge by the end consumer.

  This system is a novel combination of new technologies related to the television, cable, telephone and computer industries. It uses high bandwidth data transmission, powerful security protection methods, advanced digital switching, high resolution visual display, new controls, and user friendly interface software.

  The basic components of this text delivery system are a subsystem that prepares the text for delivery and a subsystem that receives and selects the delivered text. Some embodiments of the system include additional components and optional features that enhance the system. The system can be configured for use by bookstores, public libraries, schools, and consumers. In one embodiment, the consumer system is comprised of four subsystems. (1) an operations center, (2) a distribution system, (3) a home subsystem including receiving, selecting, viewing, trading and transmission capabilities, and (4) a billing and collection system. Alternative configurations of this system are defined to allow for various traditional and non-traditional delivery methods.

  The operations center has several basic functions, text data manipulation (including text data reception, formatting and storage), text security encoding, book cataloging, messaging center capabilities, and Execute the uplink function. In one embodiment, the system delivers text from the operations center to the consumer's home by inserting text data into the analog video signal. Text insertion is typically performed with an encoder at an uplink site that is in or near the operations center. This system can send text data using several lines of vertical blanking period (VBI), all lines of analog video signal, digital video signal or unused part of bandwidth . With the VBI delivery method, the top 10 or 20 book titles can be transmitted with the video during normal programming using existing cable or broadcast transmission capabilities without interfering with subscriber video reception. it can. Using the entire video signal, thousands of books can be transmitted within just one hour of broadcast time. Nearly any analog or digital video or data delivery system can be used to deliver text data. Text data can also be transmitted over other low-speed and high-speed signal paths, including, for example, telephone networks with high-speed connections such as ADSL connections (for example, public switched telephone networks) and the Internet. .

  The home subsystem performs at least four functions: connection to distribution system, text selection, text storage, and transaction through communication mechanism. The components of the home subsystem can be configured in various hardware configurations. Each function can be performed by a separate component, the components can be integrated, or the capabilities of existing cable set-top converter boxes, computers, and televisions can be used. Connectors, library units, and viewer units can be used. In one embodiment, the connector portion of the home subsystem receives an analog video signal and pulls or extracts text from the video. The home library stores text signals, provides a user-friendly software interface to the system, and processes transactions at the consumer's home. The viewer provides a screen for viewing text or menus and new user-friendly controls. Alternative embodiments are shown that support the delivery of text using various communication mechanisms.

  The viewing device is preferably a portable book-like viewer that provides a screen for storing and interacting with the home library unit for reading one or more electronic books. A high resolution LCD display is used for both reading books and interacting with the home library unit. An optional telephone connector or return path cable connection initiates a telephone call, transmits the necessary data with the assistance of the library, and terminates the order and the billing portion of the consumer's transaction. User friendly controls include bookmarks, current books, and page turning buttons. The billing and collection system automatically performs transaction management, authentication, collection, and payment to publishers.

  Systems similar to consumer-oriented systems can be used in bookstores, schools and public libraries.

  FIG. 1a shows an electronic book distribution system 100 that can be used to distribute electronic books. The content provider 110 can publish hard copy versions of books or other print media including, for example, newspapers, magazines, and product catalogs. The content provider 110 can convert the printed material into an electronic format and provide the material in the electronic format to the distribution center 120 via the uplink path 115. The uplink path 115 may be a wired (wired) or wireless (wireless) path. The uplink path 115 is, for example, a communication network. Uplink path 115 can be a satellite relay path or a wireless telephone path. The uplink path 115 may provide an electronic book to a distribution center using a fixed medium such as a CD-ROM.

  In FIG. 1 a, content provider 110 and distribution center 120 are shown as separate components of electronic book distribution system 100. However, the content provider 110 and the distribution center 120 may be located at the same place.

  The distribution center 120 can convert the printed material into an electronic format. Alternatively, distribution center 120 may receive electronic files from an external source such as content provider 110. Distribution center 120 may process and store electronic books.

  The distribution center 120 distributes electronic books. This distribution can, for example, via distribution path 125, distribution network 130, and distribution path 135 to an electronic book subsystem or terminal 140 that may include an electronic book viewer (not shown). The terminal can also be a television, a set top terminal, a personal computer or similar device. Hereinafter, details of an apparatus and a method for distributing an electronic book will be described. Distribution network 130 can be an e-book store, an Internet web site, a wired or wireless communication network, an intranet, a radio program delivery system, a television program delivery system, cable television, satellite television broadcast (broadcast), air.

FIG. 1b shows the components of an electronic book distribution system 170 that distributes (distributes) electronic books using a television program (program) distribution system.
In the embodiment shown in FIG. 1b, the components of the electronic book selection and delivery system 170 are an encoder 174, a video distribution system 178, a connector 182 and a text selector 186. The encoder 174 places the text data on the video signal to form a composite video signal. A composite signal may contain only text data, but usually carries both video data and text data. Various equipment and methods can be used to encode text data onto a video signal. Video distribution system 178 distributes the composite video signal from a single point of encoder 174 to multiple locations having connectors 182. Connector 182 receives a digital or analog video signal from video distribution system 178 and separates, separates or extracts text data from the composite video signal. If necessary, the extracted text data is converted into a digital bit stream. Text selector 186 works with connector 182 to select text.

  With the combination of connector 182 and text selector 186, various ways of selecting and retrieving the desired text from a composite or video signal are possible. The text can be pre-selected, selected upon receipt, or selected after it has been received and stored. One way is for connector 182 to pull or extract all text from the video signal and have text selector 186 screen all text received from connector 182. Text selector 186 stores the text in long-term or permanent memory only if the text passes the screening process described below.

  FIG. 2 shows another embodiment of the electronic book selection and delivery system 200. The delivery system 200 includes an operations center 250 including an uplink site 254, a video distribution system 208, a home system 258 including a video connector 212, a library 262, a viewer 266, a telephone connector 270, A telephone system 274, an Internet web site 279, and a billing and collection subsystem 278 are included.

Any other information associated with the delivery system 200 can be displayed. Furthermore, the television 259 and the personal computer 261 provide a control function for copying and complementing the function of the viewer 266.

  The operations center 250 receives text material from external sources 282 such as publishers, newspapers and online services. Alternatively, the external source can maintain the electronic book on the Internet web site 279. External source 282 can convert text and graphics material to digital format or contact another vendor to provide this service. The operations center 250 receives this text and graphics material in various digital formats and converts it to a standard compressed format for storage. In doing so, the operations center 250 creates a pool of text material that can be delivered to the home system 258. Text materials are grouped by book or title for easy access.

  Here, “book” means text or graphics information included in an arbitrary novel, encyclopedia, article, magazine, newspaper, catalog, periodicals, manual, or the like. The term “title” represents an actual title assigned to the book by the author, or any other designation that indicates a particular group, part, or category of text information. A title may refer to a series of related text information, a group of text information, or a portion of text data. For example, "Latest Harlequin Romance", "Four Child Reading Books (for 10 to 12)", "Britanica Encyclopedia", "President's Speech", "Instruction Manual" "July 4th event schedule", "Pet Handbook", "Low vs. Wade", and "Joy of Cooking" are appropriate titles. The title may be a graphical symbol or icon. Thus, a wrench picture can be a repair book title, a computer picture can be a computer book title, a telephone graphic symbol can be a phone book title, and a dagger picture can be a mystery book title. The picture of the bat and ball can be the title of a sports book, and the picture of a ticker tape can be the title of a business book.

  The operations center 250 includes an uplink site 254 that places text on a communication signal and sends the communication signal to a distribution system. Uplink site 254 generally includes an encoder 204 (not shown in FIG. 2) that encodes text onto a communication signal.

  Many analog and digital video distribution systems such as cable television distribution systems, broadcast television distribution systems, video distributed via telephone systems, direct satellite broadcast distribution systems, and other wired and wireless Can be used with the electronic book delivery system 200. Almost all distribution systems that can deliver communication signals including video signals can work with the electronic book delivery system 200. It is also possible to distribute electronic books without using communication signals, as described in the embodiments presented in Section VII.

  The home system 258 has five basic functions: (1) connection with a video delivery system, (2) data selection, (3) data storage, (4) data display, and (5) transactions (transactions) ). An important optional feature of the home system 258 is communication using the telephone communication system 274 in one embodiment. The home system 258 has four parts: a video connector 212 or similar type connector for connection to the distribution system 208, a library 262 for storage and processing, and a viewer 266 for viewing menus and text. , And a telephone connector 270 for connecting to the telephone communication system 274. Section VII presents additional examples directed to alternative communication mechanisms.

  The billing and collection system 278 may be located at the same location as the operations center 250 or may be located away from the operations center 250. Billing and collection system 278 may communicate with home system 258 using a telephone-type communication system (eg, 274). Any number of communication systems described in Section VII, such as a cellular system or the Internet, may work with the billing and collection system 278. The billing and collection system 278 records a portion of the electronic book or text selected and ordered by the subscriber. The collection system charges the subscriber's credit account or charges the subscriber. Further, the billing and collection system 278 is entitled to publishers or other external sources 282 that have provided other services such as text data or air time to operate the text delivery system 200. The amount can be monitored.

  Also shown in FIG. 2 is an intranet 279 '. The intranet 279 'can be used as part of a private distribution network for distributing and circulating electronic books. For example, a university library may circulate electronic books to university students and professors using an intranet 279 '.

  FIG. 3 is an expanded view of a preferred delivery plan 301 for the delivery system 200. This is a delivery plan that supports different types of subscribers and different types of billing systems. FIG. 3 shows publisher 282 providing text transfer 302 to operations center 250 'and receiving payment 306 from billing and collection system 278'. A separate channel uplink site 254 'is shown in this configuration and receives data 310 from the operations center 250'. The operations center 250 'has three independent parts (318, 322, 326). That is, a first part 318 for receiving, formatting and re-entry of text, a second part 322 for security encoding, and a third part 326 for catalog and message center functions. is there.

  The collection and billing system 278 'shown has two parts (330 and 334). The first part 330 is responsible for managing business transactions, authentication and payment to publishers, and the second is the part 334 responsible for customer service.

  The public library and school 370 can have a modified system that allows the bookstore 374 to rent or sell the viewer and sell electronic book data while checking out or renting the viewer. Not only public libraries and schools 370 but also bookstores 374 can receive cable 378 services. An optional direct broadcast system (DBS) 382 may also be used with system 200, as detailed in Section VII.

I. Operations Center FIG. 4 is an overview of an operations center 250 that includes an uplink 254. The operations center 250 collects text or books by receiving, formatting, storing, and encoding. A data stream 302 containing text is received by the data receiver 402 at the operations center. Data receiver 402 is under the control of processor 404. When received, the data stream is formatted using digital logic 406 for formatting that is also controlled by processor 404. If any additional text is generated at the operations center 250 for local insertion into the signal to be distributed, this text generation is transmitted to the data receiver and keyboard (not shown). And so on) through the text generator hardware 410. After processing by the text generator 410, additional text can be added to the received text by the synthesis hardware 414 including digital logic circuitry (not shown).

  Processing at the operations center 250 is controlled by the processor 404 using the instruction memory 416. The processor 404 and the instruction memory 416 are provided by a personal computer or a minicomputer. To perform catalog and messaging functions, the operations center 250 uses a catalog and message memory 420 and, if necessary, a text generator 410.

  The text, catalog, and message data streams may be encoded by the security encoding module 424 before being sent to the uplink module 254. The security encoding module 424 can use various encoding techniques such as commercial derivatives of the NSA encryption algorithm (Data Encryption System (DES)) and DigiCipher II of General Instruments. . After encoding, the encoded text may be stored in text memory 428 before being sent on uplink 254. A first-in first-out text memory configuration can be used under the control of the processor 404. Various types of memory, including RAM, can be used for the text memory 428. The operations center 250 can use file server technology for the text memory 428 to catalog and spool books for transmission as described below. The operation center 250 can store an electronic book as a compressed data file.

  In one embodiment, to transmit text data, distribution system 208 (see FIG. 2) is as defined by the North American Broadcast Teletext Standard (NABTS) and World System Teletext (WST) standards. High bandwidth transmission techniques can be used. Using the WST format (each line in the vertical blanking period includes 266 data bits), for example, a 400 page book can be converted to approximately 1 in 1.6 minutes using four lines in the vertical blanking period. Book rate (63840 bits per second, which can be transmitted during normal television programming). Alternatively, books can be transmitted over a dedicated channel, in which case programming is interrupted and approximately 2250 books per hour (3.9 megabits per second) using 246 lines of video. Can be transmitted. The teletext type format is the simplest but probably the slowest text format for use with this electronic book delivery system 200. In any case, at uplink site 254, encoder 204 is used to insert text data into the analog video signal. In many other respects, the delivery of text information can be done using existing cable television plants and equipment. Alternative transmission formats and delivery systems are presented in Section VII.

  FIG. 5a is a flow diagram of the steps that occur at the operations center 250 related to processing text from a publisher or provider 282. FIG. As shown in block 500, publisher 282 processes the text data file of the book, compresses the data file, encrypts it, and sends it to operations center 250 or uplink 254. You can send a text file of books as if it were one book at a time. As indicated at block 504, uplink 254 or operations center 250 receives the data stream from publisher 282 and processes it. In general, part of this process includes encryption and error correction. The text file can be delivered to be received simultaneously by multiple home subsystems, or can be delivered to a particular individual home subsystem.

  In FIG. 5a, an electronic book is distributed to consumers using a video distribution system such as a cable television system. However, electronic books can also be packaged as data packets and distributed via other communication networks, such as a digital wireless telephone network.

  In some embodiments, as shown in block 508, the file is divided into smaller packets of information. Header information is added to the packet. The bit stream is converted from a serial digital bit stream to an analog bit stream compatible with NTSC video signals. Block 512 shows the switching of the analog data video signal to the video line. Analog data can be placed on either the VBI or the active video line. In some cases, unused portions of bandwidth (such as 5 to 40 MHZ, 70-75 MHZ, 100-109 MHZ or other guard bands) can be used instead of video lines. An alternative transmission method is presented in Section VII.

  FIG. 5 b is an example hardware configuration that performs some of the functions for blocks 508 and 512. Video feed 516 is received via sync stripper 520 and processed. Stripped sync signal 532 is used by digital logic control 524. Digital logic control 524 receives synchronization signal 532 and serial digital bit stream 528 for processing. Digital logic control 524 sends the serial digital bit stream to digital to analog converter 536 and outputs a control signal 540 for video switch 544. Video switch 544 integrates video feed 516 and analog data stream 548 into video feed 552 with an inserted analog data signal.

  As an alternative to cable, satellite, broadcast, or television delivery methods, the public telephone system can be used to transmit the book to the subscriber. Through the public telephone system, an average book is transmitted in about 7 minutes. With a telephone system, it is not necessary to combine video and text into a composite signal. In most other respects, the operations center remains the same whether the text delivery is by telephone or cable. ("Audio / Video File Server Decoding / Playback Means" granted to Mincer et al. In US Pat. No. 5,262,875 and Noveck et al. In US Pat. No. 5,218,695). The file server technology (as described in the given “File Server System Highing-Speed Write Execution”), which is incorporated herein by reference, together with the text delivery method by the telephone system, is the operation center 250. Is preferably used.

  As an alternative to delivery by cable, television, or telephone system, a public telephone system can be used to access the Internet and access the Internet web site 279. A telephone system can be used to order electronic books, make payments, and deliver them directly from Internet web sites.

  When distributing electronic books using a wireless telephone network or otherwise communicating with a home system 258, the home system can receive data using any one or more standard protocols; The optional one or more standard protocols include time division multiple access (TDMA), code division multiple access (CDMA), Global Systems for Mobile Communications (GSM), and advanced mobile telephone systems ( AMPS) protocol.

  In any delivery system that uses a telephone system, by incorporating other communication devices such as high-speed modems, integrated digital network (ISDN) connectors, or using asymmetric digital subscriber lines (ADSL) Thus, individual subscribers can increase the delivery speed of electronic books. These alternative delivery methods are presented in Section VII.

The home system 258 provides user friendly interface controls and software that receives data and video transmissions, strips (or extracts) data from video signals, screens and stores data, and menus and software. It performs several functions, such as displaying text, processing transactions, initiating telephone calls, and transmitting billing data. Various hardware configurations can be used to achieve the desired function of home system 258. For example, as shown in FIG. 6b, home system 258 utilizes the currently installed subscriber base of cable converter box and television 601 and the network computer's receive and channel tuning capabilities. It can be constituted as follows. The home system 258 can also be designed as an advanced set-top terminal converter box, described below in Section V with menu generation capability, electronic memory, and telephone modem. Alternatively, the home system 258 can be configured to support alternative delivery and ordering methods as described in Section VII.

  The electronic components that make up home system 258 can be configured in various ways. In the four unit system of FIG. 6 a, viewer 266 and library 262 are wired together, while the remaining components communicate via RF transceiver 604. In a simple version of home system 258, there are only two units, library 262 and viewer 266. FIG. 6b shows a two unit home system 258 with certain optional features.

  The viewer 266 includes a high resolution viewing area 602, digital logic (including key 605, security 606, and microprocessor 621), video graphics control and memory 607, and power supply circuit 602 (not shown). ), An optional battery 603, and an optional RF transceiver 604. In the two unit configuration, the library unit 262 includes a connector function to the video delivery system 208, a connector function to the public telephone communication system, and a memory 600 (which may be a removable portable 600 '). More particularly, library unit 262 includes data strip function 617, digital logic 609, memory storage 600, power supply circuit 610, and optional telephone connection 611 (including cellular or PCN 611 ′); Includes an optional battery (not shown), an optional tuner module 613, and an optional RF transceiver 604. Video connector 212 and public telephone system connection 270 may be separated into separate components, similar to removable portable memory unit 600 of library unit 262. (FIG. 6b shows a removable portable hard disk memory 600 ′ with a removable cartridge 614.) Finally, the home system 258 includes an attached keyboard 267 or a wireless keyboard 268. including. The attached keyboard 267 and the wireless keyboard 268 are both used to communicate with the viewer 266 or the library unit 262. The wireless keyboard 268 can communicate via, for example, radio frequency (RF) signaling.

  In an alternative arrangement, all functions of the home system 258 can be incorporated into a single unit. For example, the functions of the library 262 can be performed by a card or chipset in the viewer 266. All communication devices required to couple home system 258 to various communication networks can also be incorporated into this viewer. All interfaces between the home system 258 and the subscriber can be included in the viewer 266. In this example, the viewer 266 can include a communication device for receiving input from a separate keyboard. The viewer 266 can also include an embedded video camera 608 "that can be used to send images to the subscriber. Using the transceiver 608, camera 608", and speaker / microphone 608 ', the subscriber can: For example, the viewer 266 can be used for video conferencing.

  Thus, the home system 258 can have as many as five separate components that communicate with each other. The two, three, four, or five separate components that make up the home subsystem can communicate with each other in various ways. This includes a hardwired connection 615, an RF transceiver 604, and other wireless methods.

  RF communication can be used at home (home, home) and separate components can be placed without restriction throughout the home. The data communicated between the units is preferably data with guaranteed security. In addition, the library 262 can supply power to the viewer 266 via the hardwire connection link 615.

  Either the cable interface device or the cable connector 212 is used to receive data and strip it from the video signal at the consumer's home. The cable connector device includes a tuner 613, while the cable interface device utilizes existing tuning equipment in the home. In either configuration, the data is separated from the video signal and stored at the subscriber's location in the library unit 262. Telephone connector 270 and modem 611 initiate a telephone call and transmit order and billing information to operations center 250 or billing and collection system 278. Alternatively, telephone connector 270 and modem 611 can be used to provide access to the Internet and to order and receive electronic books from Internet web sites. Library 262 is an intelligent component of the home subsystem and contains the hardware and software necessary to store text data, generate menus, and implement purchase transactions. In addition to the RF transceiver 604, the library 262 includes the jacks and connections necessary to allow the system to be connected to the viewer 266. As shown in FIG. 6b, the library 262 communicates text data up to the viewer 266 in a secure format that requires a key 605 for decryption. The text is generally decrypted only page by page, just before it is read.

a. Video Connector FIG. 7 shows the process flow performed by the video connector 212. The video connector receives the video signal 608, tunes to the channel that includes the text data 612, pulls the text data away from the video signal 616, and communicates the text data stream to the logic components in the library 620.

  The connection to the video delivery system is preferably a cable connector to the cable television delivery system, as shown in FIG. 6b. The cable connector includes a data stripper circuit 617, which is either a set-top converter, a TV or VCR 601, or an optional tuner block 613 that receives a CATV signal via the cable connector 212 ′. Receive video input from The data stripper circuit 617 pulls the data away from the video and outputs a digital bit stream to the digital logic portion 609 of the library unit 262. The data is embedded in an encrypted and compressed format in the vertical blanking period or active video portion of the video signal. The data stripper circuit 617 can be located inside the set top converter box 601, TV or library unit. Data stripper circuit 617 outputs a digital bit stream that is used in the digital logic 609 of the library.

  The video connector 212 can also include a channel tuner module 613, which can provide access to video containing data that is tuned to and pulled from the video channel. With the optional tuner module 613, a set top converter, VCR, or TV tuner is not required in the home subsystem. The optional tuner module 613 will instead receive the CATV signal directly via the cable connector 212. Additional connector options that enable the reception of text files using alternative distribution methods are described in Section VII. This ubiquitous access is provided using a modular connector 700 as depicted in FIG. 6b.

b. Library An example of a library unit 262 for a two-unit home subsystem is shown in both FIG. 6b and FIG. The embodiment shown here includes the following optional parts: That is, in addition to removable portable memory 600 ′, microprocessor 628, instruction memory unit 632, digital logic 636, and power supply unit 640, video connector 212, telephone connector 270, RF transceiver 604, and It is a battery pack.

  Library 262 includes a digital logic portion 609 (not shown in FIG. 8) that includes a microprocessor 628, digital logic 636, and instruction memory unit 632. The microprocessor 628 is preferably a highly reliable microprocessor such as the MotSC21 sold by Motorola. The digital logic unit 609 receives the serial digital bit stream from the data stripper circuit 617 and processes the data. Error correction is also performed by the digital logic unit 609 and the data is checked for the appropriate address. If the address of the data is correct and the library unit 262 is authorized to receive the data, the data is transferred to the memory storage units 600 and 600 '. Approval to receive data is provided by the cable headend or other distribution point. It is also possible to send the authorization code in a serial digital bit stream. The digital logic unit 609 sends appropriate text and graphics data to the memory storage units 600 and 600 '. This data is transferred in a compressed and encrypted format and stored in a compressed and encrypted format.

i. Memory Storage Unit The memory storage unit of the library unit 262 can be a removable portable memory unit (shown in FIGS. 6a, 6b and 8). Various options are available for memory storage. That is, a hard disk drive, a hard disk having a removable platter, a CD-ROM, and the like. Referring to FIG. 6b, a hard disk drive unit 600 ′ including a removable platter can also be utilized. This gives the library an almost unlimited storage capacity. Data (ie, electronic book file) is stored in a compressed and encrypted format in a memory storage unit. As shown in FIG. 6b, the data has a key or unique ID number that matches the ID or key of the viewer 266. Such a match of the unique key or ID number prevents text data from being transferred from the memory storage unit to an unauthorized viewer. Data can also be stored using small memory devices such as smart cards, electronic memory cards or PCMCIA (Personal Computer Memory Card Industry Association) cards.

ii. Power Circuit As shown in FIGS. 6 b and 8, the library unit 262 is powered from either an AC wall power source, a DC power source 640, or an optional battery power source 624. The power supply circuits 610 and 640 preferably supply all necessary voltages from either the battery 624 or the AC unit to the various circuits in the library. Preferably, the power supply circuits 610 and 640, when connected to the viewer 266, provide power to the viewer via a single data cable. The power circuits 610 and 640 can also recharge the battery using an AC power source during operation. Once the optional battery unit 624 is installed, the library unit 262 becomes a portable unit and can provide power to the viewer 266. To prolong battery life, power saving measures are taken, such as shutting down the memory system when not in use. When the viewer 266 is used, the library circuit is not used, and almost all power is cut off from the library 262.

iii. Connection to the Public Telephone System In one embodiment, the connection to the telephone system is provided by a connector device 611 comprised of a modem. A variety of available modems can be used to perform this function. As shown in FIG. 6b, a cellular or PCN telephone connection 611 ′ may also be provided. When the home system 258 is first started, the consumer's name and credit card information can be transferred to the billing and collection system 278 using a modem. The telephone connection 270 can be used each time a book is purchased by a consumer to complete and record a transaction. The telephone connection 270 can also be used to receive text data from the operations center 250 and bypass the video distribution system 208. The telephone connection 270 may be a separate unit, as shown in FIG. 6b. However, there are alternative means for connecting the home system 258 to the billing and collection system 278 or the operations center 250. A modular connector 701 (shown in FIGS. 6 b and 8) provides access to each communications network and provides a path from the home system 258 to the billing and collection system 278 or the operations center 250. These alternatives are presented in detail in Section VII.

iv. Library Processing FIG. 9 is an example for one embodiment of a process for a data stream 651 received from a video connector 212 or stripper circuit 617 performed by the digital logic section 609 of the library 262. In step S650, the digital logic section 609 checks the data stream 651 for error correction. If an error is detected, the digital logic section 609 deinterleaves the data at step S654 and runs a FEC (Forward Error Correction) algorithm at step S658. In steps S650, S654 and S658, the digital logic section 609 performs the necessary error correction on the data stream. If error correction is not required, the digital logic section 609 proceeds to step S662 and individually checks the data packet for the packet address.

  If the address is a unique address, the process moves to step S666 and the digital logic section 609 checks whether the address of the packet matches the library box ID number. The ID number of the library box is a unique number associated with the library 262 and is used for confirming the security of data. The process then moves to step S670 where the digital logic section 609 determines whether an electronic file has already been opened and data packets can be saved therein. If the data file is not open, the digital logic section 609 opens a new data file for the packet. If an electronic file is open, the process moves to step S678 and the digital logic section 609 saves the packet to that electronic file on disk. The process moves to step 682 where the digital logic section 609 checks to see if this packet is the last packet of a particular book for the particular text data block being received. If it is the last packet of information, the process moves to step 686 and the digital logic section 609 closes the electronic file and updates the directory of available electronic files. Following either step S682 or S686, the process returns (returns) to receive another data packet from the data stream received from the data stripper block.

  If the packet address is checked and it is determined that the address is a broadcast address, the process moves to step S690 and the digital logic section 609 determines the type of message being sent. This message can be, for example, an index of the title of the book, information on menus (and menu graphics), announcements, special offers, discounts, bulletins, and previews. The process then moves to step S694 where the digital logic section 609 stores the message in the appropriate electronic message file 694. The process then returns to step S650 to receive another data packet and perform another error check.

  Using the process of FIG. 9, the library 262 receives and stores directories associated with text data and graphics data (which can be used to show images in a given book or generate a menu). And can be updated. Depending on the format of the data and the operating system of the library 262, process variations are possible.

  FIG. 10 shows an example of processing an information request from the viewer 266 in the library 262. Information requests from the viewer 266 are received via a cable connecting the viewer 266 to the library 262 or via a wireless transmission such as RF. In some embodiments, the subscriber's request may come from the set top converter box 602 (see section V).

  Information requests received from the viewer 266 generally belong to three categories. That is, (1) directory data of books stored in the library 262, (2) indexes of all books available in the system, and (3) requests for specific books (step S700). In step S <b> 704, the digital logic section 609 responds to a request from the viewer 266 for a directory of data representing books stored in the viewer 266. The directory of data is sent to the viewer 266 for display to the subscriber. In step S708, the digital logic section 609 processes the request from the viewer 266 for all book indexes available in the system. The library 262 acquires indexes of all books available in the system, and transmits the indexes to the viewer 266 together with the menu information in step S712. In step S716, the digital logic section 609 responds to a request from the viewer 266 for a particular electronic book. In step S720, the digital logic section 609 opens the electronic file of the specific book requested by the viewer 266 and transmits the record or information to the viewer 266 for each packet. This process of transmitting a particular book, record, or packet to the viewer 266 continues until the last record or packet is sent in step S724.

  In addition to the process shown in FIG. 10 in processing a request for a particular book, the library 262 also uses the process described in step S716 to order a particular book from the operations center 250. receive. Following a request for a particular book not stored in library 262, library 262 determines the next available time that the book will be on video distribution system 208 or an alternative delivery system, and Proceed to ensure receipt and storage of the book (this process is not shown). In performing this process, the library 262 transmits information to the viewer regarding when to obtain text data for the book, thereby allowing the subscriber to view the electronic book. In addition to timing information, prices and other order information can also be sent to the subscriber by the library unit 262.

FIG. 11 is a block diagram of the viewer 266 showing its internal components. The viewer 266 of FIG. 11 is the same as the viewer 266 shown in FIG. 6b. The viewer 266 is designed to be physically similar to a bound book. The viewer 266 is composed of five basic components and seven optional components. (1) LCD display 602, (2) Digital circuit (not shown), (3) Video graphics controller 607 ', (4) Controls 740, (5) Book memory 728, (6) Optional Power supply circuit 736, (7) optional battery 603 ′, (8) optional RF transceiver 604, (9) optional cellular or mobile connector (eg, 611 ′), (10) optional keyboards 267 and 268, and (11) Optional speaker / microphone 608 ', (12) Optional alternative communication interface device.

  (1) A high resolution LCD screen 602 of VGA quality can be used by the viewer 266 to display text and graphics images. This screen can be the size of one page of the book. A two-page screen or two screens can also be used in the viewer 266.

  (2) A digital circuit including a highly reliable microprocessor 621, instruction memory 732, and digital logic. When data is transferred to the viewer 266, it has a compressed and encrypted format. The reliable microprocessor 621 compares the ID number of the viewer 266 with the incoming data stream and only if the ID number of the viewer 266 matches the ID number inside the incoming data stream. Store the data. The viewer 266 can be configured not to output text data or any other data, but to decompress and decode the data only when viewed and only for the page currently being viewed. These measures provide additional security against unauthorized access to data.

  (3) The viewer 266 includes a video graphics controller 607 'that can assist and display VGA quality text and graphics images. The graphics controller 607 'is controlled by the digital circuit described above. Text can be displayed in multiple font sizes.

  (4) The viewer 266 of FIG. 11 has touch panel type controls (operation devices) 740. With these unique and new controls 740, consumers can select a stored electronic book and an electronic book in the catalog, move the cursor, and turn the pages in the book Become. Typically, preferred controls 740 include next and previous buttons 742 and 741, a ball 743 for moving the cursor, one or more select buttons 745, a current book button 747, and a bookmark button 749. (See FIG. 14a).

  Controls 740 are easy to use and must be placed in a convenient location. Referring to FIG. 14 a, controls for the viewer 266 can be located below the screen 602 below the viewer 266. The next page button 742 is the most used button 740 and can be arranged at a position close to the right edge of the page. The subscriber is likely to use the thumb of the right hand to operate the controls, particularly the next page buttons 741 and 742. Therefore, these buttons are preferably arranged so that they can be easily operated by the subscriber's right thumb. Generally, this is given along the margin below the viewer 266 or on the right side of the viewer 266, as viewed. The current book button 747 and bookmark button 749 are usually the least frequently used buttons in the controls 740. Thus, in the example shown, these buttons 747 and 749 are located in an internal area near the binder of the viewer 266. The ball 743 located at the lower center of the viewer 266 or other cursor moving device (such as four pointer arrows, but not shown) is easy to use by the subscriber and easy to operate the viewer 266. It is. The select button for the cursor 745 is preferably located on the left and right sides of the ball, as shown, half down the diameter of the cursor ball 743. If the pointer arrow is used for cursor movement, the select button 745 can be placed at the center of four arrow buttons (not shown). Again, the most frequently used controls 740 should be placed where the subscriber's right thumb is normally placed.

  (5) A book memory 728 for at least one book or more text is included in the viewer 266. The memory 728 stores text and arbitrary graphics representing photos in the book. The memory 728 can also store menu graphics data. In the viewer 266, two different memory devices 728 can be used. The first is for instructions to the microprocessor 621 in the digital circuit, and the second is for the book memory 728 (and graphics). Various commercially available memory devices such as ROM, RAM, or a small hard disk can be used. Since one book requires about 0.6 megabytes of storage, a small hard disk that provides about 60 megabytes of storage can provide memory for about 100 electronic books.

  Book text can be stored in various font sizes. Various fonts are stored in the instruction or book memory 728 to provide various fonts for display. Thus, larger or smaller fonts can be recalled from memories 621 and 728 to provide the subscriber's desired display.

  (6) The power supply circuit 736 in the viewer 266 receives power from either an AC power supply, an optional battery 603 ′, or a library unit 262. The power supply circuit 736 provides the voltage required for various systems within the viewer 266.

(7) An optional battery 603 'is provided in the preferred embodiment. The battery 603 ′ is automatically recharged when AC power is available.
(8) The viewer 266 can also include an optional RF transceiver 604 that provides a bi-directional data link between the viewer 266 and other components of the home subsystem.

(9) The viewer 266 can also include a cellular transceiver (not shown) for mobile communications.
(10) Using an optional wired (attached) keyboard 267 and a wireless (eg, RF) keyboard 268 (see FIG. 6a) with the viewer 266 to communicate between the subscriber and the viewer 266. Can do.

  (11) The speaker and microphone 608 'allows the viewer 266 to provide audio signals to the subscriber and allows the subscriber to make audio (voice) input. The speaker and microphone 608 'can be used with cellular transceiver 608 or other communication devices to provide telephony and data transmission and reception.

(12) Another optional communication interface device allows the viewer 266 to use various communication paths.
The viewer 266 of FIG. 11 is utilized to provide connections to the library connection 744, electronic card memory 748, CD-ROM device 752, and portable memory device 756 (such as 600 ′ shown in FIG. 6b). Have possible parts. Various electronic memory cards, such as PCMCIA, can be used with the viewer 266 to supply and store electronic books.

  Security, low power consumption, and excellent display technology are the features required for the viewer 266 design. Viewer 266 must be lightweight and portable. The viewer 266 is software that can store, read, and erase an electronic book, and further includes a function of ordering the book and holding it in a memory for a predetermined time determined by the system operator. Includes operating system. The software can read the book for a period of time (eg, 2 weeks), then automatically erased, erased once read, or permanently retained in memory , And so on. Each viewer 266 has a unique key 605. All data storage is encrypted using a key 605 for the individual viewer 266 to prevent multiple viewers 266 from accessing text files or book files.

  FIG. 12 is a flow diagram of some of the processes performed by the microprocessor 621 in the viewer 266. The viewer 266 receives input from the subscriber via the touch panel type controls 740. In step S800, the subscriber information request is processed by the microprocessor 621 (800).

  In step 804, the microprocessor 621 selects the electronic book menu when the subscriber requests an available electronic book menu. In step 808, the microprocessor 621 opens an electronic file listing the available electronic books (related to the topic category in the menu) and displays a menu with the names of the available electronic books.

  When the subscriber selects a particular book to read, at step 812, the microprocessor 621 processes the selection to determine the electronic file that contains the particular electronic book. In step S816, the microprocessor 621 opens the file for that particular electronic book and normally accesses the first page. (If the pointer is already set in the electronic file for the book, this process will default to that page.) In step S820, the microprocessor 621 will then display which page is displayed. Decide what you need. That is, the microprocessor 621 determines whether to display the next page, the previous page, or the bookmarked page. If the pointer to the electronic file is not at the correct position, in step S828, the microprocessor 621 moves the pointer and obtains the previous page of data from the stored file. Otherwise, in step S824, the microprocessor 621 typically obtains the next page of text from the stored electronic file. In step S832, the microprocessor 621 decodes and decompresses the text data and sends the data to the video display. Video displays typically have a video display memory associated with it. In step S832, the microprocessor 621 sends the data directly to this video display memory. The display circuit then completes the process of displaying a page of text.

  When the subscriber requests to turn off the power via the controls 740 (from step S800), in step S836, the microprocessor 621 starts to turn off the power. In step S840, the microprocessor 621 saves in memory a pointer to the number of pages in the book that the viewer 266 is currently reading. In step S844, the microprocessor 621 closes all electronic files and signals the power supply circuit to shut off the power supply to the various circuits of the viewer 266. Along with these basic process examples, the viewer 266 can display a selection of books and display text from those books.

d. Menu System Referring to FIG. 13, the delivery system 200 has a menu system for selecting functions and electronic books from the delivery system 200. The operating software and memory required by the menu system 851 are located in the viewer 266 (eg, instruction memory 732 and / or book memory 728). However, it may be located in the library unit 262 (eg, instruction memory 632), and the library unit 262 and the viewer 266 may share software and memory necessary for the operation of the menu system 851. Since the menu is usually displayed on the viewer 266 and the viewer 266 can operate even when the library 262 does not exist, the basic software and memory for creating the menu are arranged in the viewer 266. It is more convenient.

  The menu system 851 allows for sequencing between multiple menus and provides menu graphics for graphical display, such as on the LCD display 602 of the viewer 266. In an e-book system that uses a set-top converter, these menus can also be displayed on a television screen. In an electronic book system using a computer, these menus can also be displayed on a computer monitor. In one embodiment, the menu provides only basic text information from which the subscriber can select. In other embodiments, the menu provides a visual display with graphics and icons to assist the subscriber, and the subscriber interaction, e-book or other content available to the subscriber. Enable real-time ordering.

  FIG. 13 shows a menu system 851 with sequencing. The basic menu in this system is an introduction menu 850, a main menu 854, and a plurality of submenus 858. In the embodiment shown, there are three levels of submenus. In some cases, one or two submenus 858 may be sufficient to easily guide the subscriber to the selected or requested information. However, there are functions that can provide a user interface that is more user-friendly for subscribers if there are more than two sub-menus 858. Each level of the sub-menu 858 can be constituted by various menus for display. The particular menu displayed depends on the subscriber's selection for the menu shown above. Examples of this tree sequence of one or many menus are help submenus 887 and 888. Depending on the specific help requested, the subscriber is presented with two different levels of help menus.

  An example of an introductory menu 850 is shown in FIG. 14a. In general, introductory menu 850 directs viewer 266 to the system and provides initial guidance, announcements and instructions. The introductory menu 850 is followed by a main menu 854, an example of which is shown in FIG. 14b. The main menu provides the viewer 266 with the basic selections or functions available in this system. FIG. 14b is an example where the main menu 854 provides the subscriber with many additional features and sub-menus 858. For example, FIG. 14b shows that the viewer 266 can select multiple options, including the following example, by a point-and-click method. (1) free (free) preview, (2) books you can order, (3) books in your library, (4) your current books, (5) help, (6) online services, and ( 7) Other system functions. After selection in main menu 854, a corresponding submenu 858 is shown.

Examples of an “account setting menu” 862 and additional submenus 858 (providing instructions and account input 864) related to setting up an account are shown in FIGS. 14g and 14h. These sub-menus 858 allow the credit card to be charged by initializing or ordering an account at the operations center 250. Submenu 858 includes the ability to enter data related to your desired PIN number or password, credit card, phone number, and the like. In one embodiment, account setup is performed using a telephone system. The confirmation menu verifies that the account (account) has been properly set up using the desired PIN or password and credit card. However, additional configuration methods are described in Section VII.

  A free preview 866 of the book is also provided by the submenus (868 and 870). An example of a free preview menu is shown in FIGS. 14i and 14j. FIG. 14i shows a menu displaying various electronic books that can be previewed for viewing. Following the selection of the electronic book, a screen sub-menu showing an excerpt from the cover of the selected book is provided along with an excerpt from the critic's book review on the selected book. In one embodiment, this preview screen for a particular book also allows the subscriber to select a submenu that gives information about the author. The book preview submenu includes still video images and graphics in which a book cover and a scene of the book are represented. An example of such a still video image or graphics is shown in Figure 14j, where a preview screen 870 for the author is shown. The author preview screen 870 shows the author's photo, gives a short biography, and allows the subscriber to order the author's books. The price for ordering the author's various electronic books can also be shown on the menu.

  In addition to the free preview, in a more advanced embodiment, the delivery system 200 provides subscribers with an electronic book recommendation function (see 855). This is accomplished using a menu system 851 and a processor with associated memory located at the viewer 266, library unit 262 or distribution point (1020 or 250). When necessary, information for the program recommendation function is sent to the home subsystem 258 as text data in a composite or video signal. According to this feature, a book or author is proposed to a subscriber based on historical data, demographic data or trends, other indicators, and / or text word searches regarding the subscriber's previous orders. The

  In an embodiment relating to book recommendation, preview information (book cover description, critic's book reviews, author biography, etc.) and / or text word search of book text or other titles may be included in the library unit. 262 is executed using a database stored in the library memory 600. Personalized book or author recommendations are made to a subscriber by obtaining information obtained from the subscriber that indicates the subscriber's interest. Entries from subscribers are preferably organized using an electronic book recommendation entry submenu 855. The system uses the entries from these subscribers directly or indirectly to search for books or authors to recommend to the subscribers.

  Generally, book recommendation methods are divided into two categories. A responsive method and an intelligent method (analyzing data and recommending an e-book). Using a responsive or intelligent method, the delivery system 200 determines a list of recommended titles or authors, creates second or third level submenus 856 and 857, and the titles are subscribed to by the subscriber. Suggest to choose.

  Responsive methods for proposing titles include, for example, the use of questions regarding trends, author searches, and keyword searches. Using the instruction memory 732 and menu generation hardware (eg, 607) of the viewer 266, questions regarding a series of trends can be presented on the menu to determine the subscriber's interest at a particular time. In this way, the processor 404 and instruction memory 416 of the operations center 250 provide each title with a light, serious, violent, short, long, bored, exciting, complex, easy to read, youth theme, for the elderly Assign trend indicators (and sub-indicators) from themes, adventures, romance, drama, fiction, science fiction, and other groups. These indicators are sent to the home system 258 along with the text data and stored in the library memory 600. Based on the subscriber's entry, the processor 404 associates the set of indicators with the subscriber's request, finds the set of electronic books that match the indicator, and proposes to the subscriber.

  Responsive searches for authors or keywords (search words provided by subscribers) are typically performed by the library processor 628 and instruction memory 632 for data stored in the library memory 600. For example, keywords provided by subscribers can be searched for matches in library memory 600 that stores book reviews, critics, and preview databases. In this way, if the subscriber is providing an entry for the word “submarine” on the appropriate submenu, the microprocessor 628 uses the instructions from the routine in the instruction memory 632 to “red” A title “Hunt for Red October” can be placed.

  Intelligent methods of proposing programs include analyzing personal profile data about the subscriber and / or historical data about the subscriber, such as books (or purchase data) previously ordered by the subscriber. It is. This method is preferred for book on demand systems and can be performed at the distribution point or operations center 250 by the on-site processor 404 using a subscriber database stored in memory 428. The home system 258 receives text data including distribution points and program suggestion information from the operations center 250, receives the same text data 212 and the above-mentioned viewer menu generation hardware (eg, 607, 621). Is used to generate program proposal submenus 855 and 856. Software routines and algorithms stored in the instruction memory (eg, 632, 732) are used to analyze historical data and book order data to determine book lines to be proposed to the subscriber.

  The algorithm for this powerful feature of recommending books and authors to subscribers is US Pat. No. 5,798,785 dated Dec. 2, 1993, “Terminal for Sugging Programs Offered on a Television Program Delivery. It is disclosed in detail in “System”. This US patent is incorporated herein by reference.

  Referring to FIG. 13, a plurality of submenus 858 are shown on a submenu 872 of “Books in Your Library”, preferably divided into bookcase numbers with submenus for each bookshelf 874 and 876. The sub-menu above the sub-menu 858 “books you can order” is similarly divided into sub-menus by bookshelves 880 and 882. Each of these bookshelves can be a book category or genre. Electronic books can be grouped into categories such as bestsellers, novels, fiction and romance. See Figure 14d.

  Referring to FIG. 13, a sub-menu 858 of “Your current book” 884 allows the subscriber to select the current book 884 and determine which page to read next. This selection can be confirmed using the level 2 submenu 885. Help submenu 887 can provide the subscriber with an additional help screen 888. The submenu 858 for the available functions 890 can be divided into separate submenu sequences for the respective functions 891 and 892.

  Referring to FIG. 13, the delivery system 200 can be used to send a message. The level 1 message screen allows the subscriber to select from various messages 893 that the subscriber has. Each message is then shown on a separate submenu screen 894 and 895. The message can include text and graphics.

  Referring to FIG. 13, account information is shown above the level 1 submenu 896, followed by a submenu 858 showing recent orders and your account deduction 897. There is also a level 1 submenu for outgoing messages 898 with a subsequent submenu used as input screen 899.

  Many other variations and functions are possible in addition to the specific functions and submenus shown in FIG. 13 and FIGS. 14a-14j. When the book is finally selected for reading, a title page 886 appears on the screen, followed by a page of text.

III. Billing and Collection System The Billing and Collection System 278 (shown in FIGS. 2 and 3) uses the latest technology in electronic commerce and telephone exchange, tracks orders, authenticates delivery, and charges consumers. , Automatically pay the publisher. A telephone call initiated by telephone connector 270 is received by billing and collection system 278, which responds immediately without human intervention by taking an order and charging the consumer's credit card account. . The data is compiled periodically and publisher 282 receives payment for book sales. The billing and collection system 278 can also connect to subscribers via a two-way cable connection, cellular or other communication means.

  The billing and collection system 278 preferably communicates with the operations center 250 to track changes relating to available books and to provide statistical data to the operations center 250.

IV. Public Library, School and Bookstore System The electronic book system according to the present invention can be modified for use in public libraries, schools and bookstores. FIG. 15 illustrates a possible configuration of components for public library, school or bookstore locations. The main unit in a public library, school or library is a file server 900. The file server 900 is a large electronic memory unit that can store thousands of books. Various electronic storage means such as a hard disk, a read / write type CD-ROM, and a read-only CD-ROM can be used for the file server.

  This system is composed of five components. A converter or video connector 904, a controller 908, a viewer 912, and a catalog printer 916. Software for controlling the system is basically arranged in the controller 908. Converter or video connector 904 is similar to that described above. In this configuration, the controller unit 908 monitors data being transferred to the file server 900 by the converter 904. The controller 908 preferably includes a screen for viewing and a plurality of control buttons. If it is necessary to have a larger screen to perform a higher degree of control of the system, the viewer 266 can be connected to the controller 908 and the viewer screen and controls 740 can be used. it can.

  For security reasons, the controller 908 can download the book only to public viewers 912 that are authorized to receive the book from a particular file server 900. For security reasons, it is not desirable for the public viewer 912 to access multiple file servers 900. In this way, security regarding the text data of the book can be maintained. The public viewer 912 can be restricted to receive one or two books at a time from the controller 908. When a user of the public viewer 912 needs a new or additional book, it can return the viewer 912 to the school or library where it can receive a new book from the controller 908.

  In order to track available books on the file server 900, the titles of available books can be printed on the catalog printer 916. The catalog printer 916 is connected to the library controller 908, and book titles are downloaded to the catalog printer 916. The coded text of any book cannot be printed using the controller 908 and catalog printer 916 of this system. In order to maintain data security, no book data is permitted to be downloaded to the printer 916. Once a complete printout of available electronic book titles, magazines or other text material is complete, a hard copy of catalog 920 can be maintained on file server 900.

  The system shown can also be used in bookstores. The bookstore can rent a public viewer 912 to the customer and load the text of one or two books into the public viewer 912. The public viewer 912 can have an automatic timeout sequence. This time-out sequence erases the text data of the book after a certain period of, for example, about two weeks. At the end of a period of about two weeks, the borrower is expected to return the public viewer 912 to the bookstore and receive additional books for reading. Using such a configuration, the bookstore can also sell the viewer 912 (permanently) to regular customers. In that case, the patron can sometimes stop by the bookstore to receive the text data of the book and store it permanently on his own viewer 912. For bookstores, schools, and libraries, various other configurations using the file server 900 and viewer 912 described above are possible.

V. Use of set-top converters Existing set-top converter boxes, such as those made by Scientific Atlanta and General Instruments, are currently book selections of the present invention. It is not designed to handle the system. While it is possible to create set-top converters that include library functionality, hardware modifications are required to use the book selection system of the present invention with existing set-top converter technology.

  16a and 16b are examples of hardware modifications or upgrades. The hardware upgrade described later is attached to the set-top terminal using the port. Two upgrades are possible for the set-top converter 601 to assist in receiving and selecting an electronic book: a menu card upgrade (FIG. 16a) and an information download unit (FIG. 16b). Each of these upgrades can be connected to the set top terminal unit via an upgrade port. The upgrade can be connected to the set-top converter 601 using a 4-wire cable, ribbon cable, FireWire (IEEE 1394B) interface connector, USB connector, or the like.

  The addition of a card 950 to the set top converter 601 is shown in FIG. 16a. The card 950 shown provides the additional functionality necessary to use a book selection system with existing set-top converter 601 technology. The card 950 can be configured to be inserted inside the frame of the set top terminal and become part of the set top terminal, an advanced set top terminal. The basic functions that the card 950 adds to the set-top converter 601 include data signal interpretation, menu generation, menu sequencing, and, ultimately, using either a television or viewer 912. Ability for subscribers to select books. In addition, the card 950 provides a way for a remote location, such as a cable headend, to receive information about the ordered book. Book ordering information and control commands can be passed from the cable headend to the card 950 using a telephone line or alternative ordering method described in Section VII.

  The basic components of the card 950 are a PC chip CPU 952, a VGA graphics controller 954, a video combiner 956, a logic circuit 958, an NTSC encoder 960, a receiver 962, a demodulator (not shown), a dialer. It is a connector 611 'comprised by these. Card 950 operates by receiving a data text signal from the cable headend via a coaxial cable. The logic circuit 958 of the card 950 receives data 964, an infrared command 966, and a synchronization signal (not shown) from the set top converter 601. Menu selections made by the viewer 266 on the remote control are received by the IR device of the set top converter 601 and passed to the card 950. Card 950 interprets the IR signal and determines the book (or menu) selected by the subscriber. Card 950 modifies the IR command and sends the information to set top converter 601. The modified IR command includes channel information required by the set top converter 601. Using phone line 968 and dialer 611 ', card 950 can send electronic book order information to the cable headend. It is also possible to receive electronic books via telephone lines or other communication networks including wireless networks and bypass the video distribution system.

  These commands may be sent over an interface that links the microprocessor of the set top terminal with the hardware upgrade microprocessor. In this way, the subscriber's input is entered via the keypad or remote control of the set top terminal, but can be forwarded for processing to any hardware upgrade and generated there. The response can be sent back to the set top terminal for display. In the preferred embodiment, IR command 966 is forwarded from set top terminal 601 to a hardware upgrade.

  Hardware upgrades include a microprocessor, interactive software, processing circuitry, bubble memory, and long-term memory devices. In addition to these basic components, hardware upgrades may utilize additional telephone modems or CD-ROM devices.

  The information download hardware upgrade 1001 (FIG. 16b) allows subscribers to download large amounts of information from the operations center or cable headend using the set-top converter 601. The hardware upgrade 1001 allows a subscriber to download data such as books and magazines to a local storage. Basically, hardware upgrade 1001 is an additional local storage unit (eg, hard disk, floppy, optical disk or magnetic cartridge, as shown in FIG. 16b, microprocessor 1005, instruction memory 1007, and may include RAM). Preferably, an upgrade 1001 is also provided for a small portable viewer 266 that allows the downloaded text to be read without using a TV.

  The downloadable information is text or graphics supplied by the operations center 250 or cable headend. With this upgrade, books can be downloaded and read anywhere using a portable reader 266. With this upgrade, books can be downloaded, stored in a compressed format, and later decompressed. Defrost the book only when you see it. Important text that the public wants to access immediately will be available using this system. Presidential speeches, new laws, and the latest judgments made by the Supreme Court can be made immediately available.

  In one embodiment, the book order information is stored at each set-top terminal until it is polled by the cable headend using a polling request message format. An example of the polling request message format is composed of six fields. (1) Rise flag at the start of the message, (2) Address field, (3) Subscriber area designation, (4) Set top terminal identifier including polling command / response (ie P / F) bits , (5) Information field, and (6) Last falling flag of the message. A similar response frame format for information communicated by the set top terminal to the cable head end in response to a polling request can also be used.

  FIG. 17 shows a preferred set top terminal including a data receiver 617 'and a data transmitter 1011. The data transmitter provides upstream data communication capability between the set top terminal 601 and the cable headend. Upstream data transmission is achieved using the polling system described above and further using the data transmitter 1011. Both the receiver 617 'and the transmitter 1011 can be incorporated into the set top terminal 601 itself or can be added via an upgrade module. Regardless of the specific hardware configuration, the data transmission capability of the set-top terminal can be achieved using the hardware shown in FIG.

  FIG. 17 shows an RF signal received when the data receiver 617 'and the tuner function together. Both of these devices have an interface with a microprocessor 1013 that receives input 1015 from the subscriber, either via the keypad, remote control or viewer 912 of the set top terminal. All cable signals intended to be received by the subscriber's TV are accessed by tuner 613 and then processed by processing circuit 1017. The processing circuit 1017 typically includes additional components (not shown) for descrambling, demodulation, volume control, and remodulation on the channel 3 or 4 TV carrier.

  Data destined for individual set top terminals is received by the data receiver 617 'according to the specific address or ID of each set top terminal. In this way, each addressable set-top converter receives only its own data. The data receiver 617 ′ receives the data specific to the set top converter 601 in the information field of the signal frame already mentioned or on a separate data carrier placed at the appropriate frequency in the incoming spectrum. To do.

  Any data received includes information about the book and menus available for selection. The subscriber enters a series of commands 1015 using a keypad or remote control to select a channel or program. Upon receipt of such a command, the microprocessor 1013 instructs the tuner to tune to the appropriate frequency of the channel carrying the data, and then initiates processing circuit 1017 to descramble this data. To order.

  When a book is selected, the microprocessor 1013 stores all selection information in local memory (not shown) and later returns the data to the cable headend. The microprocessor 1013 coordinates all CATV signal reception and further interacts with various upstream data transmission components. Typically, the data transmitter 1011 operates in the feedback frequency band of 5 to 30 MHZ. In another embodiment, a frequency band of 10 to 15 MHZ is used. However, regardless of the frequency band used, the data transmitter 1011 sends information to the cable headend in the information field of the response frame already described. One skilled in the art can consider many variations, and upstream data transmission can be achieved using a combination of hardware components of the set top terminal described above.

VI. Book-on-demand system (Book-On-Demand System)
The electronic book system 200 described in this application can also be configured in a book on demand style. FIG. 18a shows an example of a configuration for a book on demand system. A book-on-demand system provides a more powerful two-way communication between a consumer's home, bookstore, school, or public library and either a distribution site 1020 such as an operations center 250 or cable headend. I need. In some embodiments, this type of bi-directional communication may be provided by the hardware shown in FIG. 17 and described above. Additional methods relating to other communication paths are described in Section VII.

  Referring to FIG. 18a, in the book on demand system, the subscriber selects a book to download from an available menu for the book. Available menus are typically sent by the distribution site 1020 to the subscriber's location. After he selects, information about his selection (or request) is communicated to either a distribution point 1020 (such as a cable headend) or an operations center. Upon receipt of this request, the text and graphics information required for the book is spooled and sent to the subscriber. In this way, books are sent only when requested by the subscriber and immediately upon request for a book (or text).

  In order to support such demand systems, the transport and distribution of text is carried out on public node distribution systems such as video-on-demand cables and telephone television systems. Must be made through the use of individual telephone calls on the telephone system or cellular telephone system, through the use of the Internet, or with several other data network options.

  According to the book on demand system, the subscriber can select a book more strongly, and the amount of unnecessary or unnecessary book data communication can be limited. It also provides e-books to subscribers much more quickly.

  In addition to the more powerful distribution system, the book on demand system requires the distribution point 1020 to be equipped with a more sophisticated device for spooling out text information. This can be accomplished using file server technology 1024 for storing books or telephone type switching (not shown) for distributing text information. A file server 1024 and distribution techniques that can be used to construct such a book on demand system are described in previously cited US Pat. Nos. 5,262,875 and 5,218,695. Has been.

  FIG. 18a shows an embodiment of a book on demand system using file server technology. In addition to electronic books, the embodiment of FIG. 18a supports almost any digital data distribution. Electronic books or text files are received from publisher 282 and other sources, through local feed 1032, ATM 1028, or by satellite dish 1036. Preferably, distribution point 1020 is a cable headend that receives requests from subscribers and delivers text via a two-way communication system (such as a video on demand (VOD) 1044).

  Library 262 may be a basic premium type service cable system 1048, a near video on demand type cable system (or pay-per-view (PPV) 1052), or a video on demand cable system. 1044 can be connected. When connecting to any of these three systems, the library 262 can access the cable directly or access the system via the set-top terminals 601 ′, 601 ″, 601 ′ ″. You can also

  With the interactive video on demand system 1044, when a subscriber requests a specific book title, it can receive that text immediately after the request. To accomplish this, the distribution point 1020 transmits a list of available books to the library unit 262 via the cable distribution system. Library unit 262 displays a list of available books on a menu or similar format. As noted above, library unit 262 preferably uses a menu that lists the categories of available books and forms a request from distribution point 1020. After selecting the electronic book, the library unit 262 sends a request signal to the distribution point 1020 on the bidirectional communication system 1044. This request signal can be processed in two ways. Either the library unit 262 initiates a request, or the distribution point 1020 polls the various libraries onto the interactive system 1044. When a request for a book title is received, the text associated with the book title is transmitted using the bidirectional cable system 1044.

  FIG. 18b is an enlarged view of an operations center 250 that supports a regional or national book-on-demand system. In fact, the operations center 250 shown supports the distribution of almost any arbitrary digital data. The operations center 250 supports multiple feeds that receive digital information by tape 1060, 1060 ', ATM 1028, or satellite 1036. The information reaches the master file server 1072 after being processed through the input MUX 1064 and the small file server 1068. Digital data such as books received from the publisher 282 is stored in the master file server 1072. Digital data is preferably compressed and stored in a standard format such as MPEG2.

  The system controller 1076 controls the regional or national book on demand system. Electronic books are packaged by group and provide feeds to various cable headends. Further, scheduling and market research are performed at the operation center 250. In order to process scheduling and market research, electronic book purchase data is received at the operations center 250 via the multiplexer 1082. Electronic book purchase information can be provided from the operations center 250 to the billing and collection subsystem.

  The operations center 250 also has a function of inserting messages and advertisements into the file server. These messages and advertisements are ultimately received by the subscriber.

  Master file server 1072 uses output multiplexer 1080 and ATM 1028 in addition to satellite connection points for distributing digital data. In the preferred embodiment, the cable headend receives text data about the book from the master file server 1080 via output multiplexer 1028 and ATM system 1028. Upon receipt of the digital book data, the cable headend stores the book in the local file server 1024. Distribution point 1020 of FIG. 18A is an example of a cable headend that receives data from operations center 250 of FIG. 18b via ATM hookup 1088 or satellite hookup.

VII. Alternative Delivery and Ordering Methods Electronic books and related data, including electronic book menu data, can be provided to subscribers by using an on-demand delivery system. Here, the electronic book is delivered after the order is received by the delivery system. The delivery system provides the electronic book in real time or near real time (ie, near on demand), or after a delay period that allows the delivery system to process, package, and send the electronic book. can do. Alternatively, the delivery system can broadcast one or more electronic books in a continuous manner. In this embodiment, the subscriber designates a desired electronic book from the broadcasted electronic book list. This delivery system, or an associated authentication system, can provide a local authentication code that allows the subscriber to decrypt, store and view the desired electronic book.

a. When using a TV program / broadcast delivery system for delivery of electronic books i. In addition to advances in television broadcast technology, government regulators impose requirements on the broadcast television industry. In particular, broadcast television networks over the air will move to high definition television (HDTV) or digital broadcast television standards in the near future. These broadcasters can choose to provide a single HDTV digital signal in the allocated bandwidth. In this case, the remaining bandwidth is used for standard definition television (SDTV) digital programming. Alternatively, broadcasters can choose to use their bandwidth for services related to data, such as electronic book delivery.

  This embodiment relates to an electronic book delivery system using a digital television program delivery system. This embodiment can be used in at least two regions. In other words, distribution of e-books embedded in broadcast digital multiplex signals using terrestrial air media and embedded in broadcast digital multimedia signals via existing cable television systems E-book delivery.
