    摘要： A system for simulcasting a fully interactive program with a normal conventional program in the same standard video signal bandwidth. It allows active participation by subscribers who have interactive components connected to a television or personal computer display, as well as normal viewing of the conventional program by viewers with conventional television sets. Interactive participants are not limited to any particular reception system. Users can participate using an interactive program box connected to a standard television set or with a multimedia personal computer with an interactive board. An important feature is that interactivity is offered as an option, without any degradation or interruption in program content to users who choose not to interact or do not have the interactive components. Interactivity is personalized through the use of alternative audio responses and/or graphic displays. The interactive elements are presented to the subscriber either immediately after subscriber entry, later during the program at predetermined times, and/or at transparent "trigger points". At trigger points, program content is subtly altered to present specialized attention to each interactive subscriber viewing the displayed programming. Interactive programs viewable over the simulcast system include both live broadcasts as well as recorded programs. Interactive audio and graphics elements can be provided as part of the transmitted video signal bandwidth using efficient one way techniques or from local or external storage. The interactive innovative features are not limited to conventional cable or television broadcast or any particular transmission means or transmission format, and can be analog or digital.

    摘要： An interactive distance learning system which provides individualized and meaningful interactive responses to each student, as if the student is receiving instruction directly from a private tutor or instructor. An interactive program transmission occurs to a diverse number of facilities and locations. The primary transmission is a live lecture by the person making the presentation on the distance learning system. The live lecture is accompanied by questions to gage comprehension by students. The questions, in interrogatory form, are graphically displayed on the screen either as video or overlaying the video showing the lecturer. In addition to the interrogatory question, a set of responses, one correct, the rest incorrect, are also presented for the student choice. A complimentary suite of affirmative supportive commentary is prepared and prerecorded for the plurality of correct and incorrect responses which might be given to a question. Each response teaches, confirms and encourages the learning experience. A processor, branching codes and a memory device can be used to create a large variety of responses to provide an individual response for every student who responds to an interrogatory. A different response is created for every answer given to every question. Video or disk recordings of presentations can be prerecorded to demonstrate concepts or ideas or simply expand on lectured points and can be switched in and out of the video presentation of the live lecture as the instructor chooses. The transmitted interactive signal can be recorded for later playback and remain fully interactive. An extremely flexible, relatively inexpensive system is thus created which uniquely teaches and uniquely addresses the needs of every student participating in the interactive distance learning system experience.

    摘要： An interactive cable television system is disclosed which utilizes a standard cable television distribution network for simultaneously providing a plurality of viewers with an interactive television program comprising a plurality of signals related in time and content. Video signals are transmitted in a digital format, more than one signal being multiplexed onto a data stream on a single channel. The video signals may be compressed for efficiency. A receiver, in conjunction with a signal selector, selects a particular NTSC channel for playback, then selects a particular video signal from the data stream, and decompresses the video signal for playback. Seamless switching between video signals on different channels is provided. An alternative embodiment is disclosed wherein the various signals which comprise the interactive program are switched at the head end rather than at the receiver. The multiple choice control unit selects a desired signal by relaying the multiple choice selections of the user through a relay box back to a remotely located switching station. The switching station routes the correct video signal down the appropriate cable channel for the particular user.

    摘要： A voice recognition interactive conversational apparatus employs temporally related data storage tracks containing interactive conversational content. The conversational content is stored on each track in information segments. Each of the segments forms a complete message reproducible in response to the selection of the track upon which the segments are stored. Each information segment includes interrogatories having vocal responses, responsive messages, informational messages, or combinations thereof related in time and content to information contained on at least one other track. The information is stored on the tracks in a predetermined timed sequence for providing interactive conversation dependent on the verbal responses. A playback device facilitates playback of the conversational content. A track selector randomly accesses the tracks for retrieving and play back the information stored thereon via the playback device. A voice recognition controller receives vocal responses to the conversational content and causes the track selector to switch between the data storage tracks based upon the vocal responses in accordance with the interactive conversational content.
