In the unified system, means (205) and methods employing computer systems have the ability to generate specific information to a particular user, simultaneously with each station (26) a plurality of subscriber stations ( 26).

Signal processing apparatus and methods.

A system of distributing video and/or audio information employs digital signal processing to achieve high rates of data compression. The compressed and encoded audio and/or video information is sent over standard telephone, cable or satellite broadcast channels to a receiver specified by a subscriber of the service, preferably in less than real time, for later playback and optional recording on standard audio and/or video tape.

Audio and video transmission and receiving system

Provided is a method and system for the electronic distribution of product redemption coupons to remote personal computers located at users' homes. A centrally located repository, such as an online service provider or web site on the Internet, stores packages of coupon data for downloading on demand to the user's computer. The user may view, select, sort and print desired coupons from the downloaded package. The user's demographic as well as coupon selection data is provided back to the online service and coupon distributor and issuers for subsequent marketing analysis. The online service can perform subsequent coupon processing on previously downloaded coupon packages such as variation of discount amounts. The online service provider can also determine how many times a particular coupon was viewed. When the printed coupons are presented at a retail store, the discount is provided to the user. Upon redemption by the store via a coupon redeeming center, transaction data is also supplied to the coupon issuers and distributor for integration into marketing analysis. The electronic coupon system is secure due to the inclusion of user-specific identification indicia printed thereon.

Method and system for electronic distribution of product redemption coupons

A data processing system issuing electronic certificates (6) through 'online' networks of personal computers, televisions, or other devices (3) with video monitors or telephones. Each electronic certificate (6) includes transaction data and identification data, and can be printed out on a printing device (4) linked to a consumer's personal input device (3), or electronically stored in a designated database (5) until a specified expiration date. The certificate can be used for various purposes, including use as a coupon for a discounted price on a product or service, proof of a gift or award, proof of reservation, or proof of payment. Consumers access the data processing system online, browse among their choices, and make their selections. The data processing system provides reports on the selected certificates and their use following selection. Certificate issuers (1) also have online access to the data processing system and can create or revise offers, and provide various instructions pertaining to the certificates to be issued, including limitations as to the number of certificates to be issued in total and to each individual consumer.

Interactive marketing network and process using electronic certificates

A system is provided for interactively and selectively communicating particular multimedia presentations to each of a plurality of subscribers along a CATV cable network. The subscriber communicates his selections, both for viewing particular presentations from a menu and for transactions with respect to the information and products being viewed, by entering codes on his Touch-Tone telephone pad. Subscriber input signals are communicated as digital signals through the intercommunications network and response signals are generated, ultimately as analog TV signals for viewing by the subscriber.

Interactive multimedia presentation and communications system

A viewdata system and decoder apparatus for providing interactive communication between a host computer and a consumer which utilizes, without modification, a conventional television receiver. The system utilizes telephonic communication, the handset of a telephone being positioned upon an acoustic coupling arrangement of the housing of the decoder. The decoder automatically carries out logon and logoff procedures through the utilization of memory retained character sequence which are transmitted at predetermined rates. A small, hand-held keypad provides for user interaction with the host computer, such keypad being coupled with the decoder housing through an elongate cable.

Viewdata system and apparatus

A system and apparatus for providing information exchange between a host computer facility and a remotely located user terminal. The host facility includes an audio memory under the control of a host computer which, in response to requests from the user facility is actuated to transmit audio information to the user terminal. During this audio mode of operation, carrier tones are removed and telephone interface components associated with the user terminal and host facility are enabled. The system further includes an interactive audio mode of operation wherein two-way telephonic communication is established between an intermediary or operator associated with the host facility and the user terminal. The related computer programs of the host facility and user terminal are configured such that control over the user facility from the host facility is emphasized.

Audio-enhanced videotex system

Substantial efforts to establish standards for encoding and accessing electronic resources have occurred over the past five years. We have designed a Web-based tool, called Spectrum, to enable individuals without specialized knowledge of library cataloging or markup to create records for describing and accessing networked electronic resources of various types. System users may create descriptions of electronic resources and view them as formatted USMARC bibliographic records, TEI headers and URCs. Because we anticipate continued volatility in the definition of data element standards, the Spectrum system is designed to allow maximum flexibility in the design of the input formats.

Spectrum: a Web-based tool for describing electronic resources

WordView is a tool that shows how words are used in naturally occurring phrases to support the intelligent parsing of such phrases. It embodies an easy to understand graphic summary and a user-controllable inspection facility.

WordView: understanding words in context

Unless you have a hardware clock on an accessory board and have set up an AUTO‐EXEC file to automatically set your PC's internal clock from the hardware clock, the first thing you must do each time you start or reboot your system is enter the current date and time. If you're feeling lazy, or you've lost your watch, you can press when DOS asks for the date and again when it asks for the time, and DOS will come right back with the familiar A> prompt. There is a problem with doing this, though.
