    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: A computer-based system for collecting and displaying weather information includes a microprocessor-based computer programmed to receive digital signals encoding weather data collected at each weather station; and to store and retrieve those digital signals in predetermined screen buffers to generate weather data screens displaying alphanumeric and graphic displays of weather data. The system further includes multiple weather stations, each comprised of one or more weather instruments, each capable of sensing a particular weather parameter and converting that parameter into a analog electrical signal, with means for converting the analog signal into a series of digital signals corresponding to the values of the weather parameter over time. The system further including means for communicating the digital signals from the weather stations to the computer and means for displaying the data screens to multiple end users in real time. Remote weather stations are connected to the computer by conventional modem/telephone hookups. Display screen data output from the computer is converted to a television broadcast quality signal so that the data screens may be broadcast or otherwise delivered to television viewers through conventional television delivery systems.

    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: A teletext system provides teletext services and teletext support services in a multiservice communication system. Multiplexed data streams for a plurality of services, including teletext data, are transmitted in a sequence of frames between a transmitter location and a receiver location. Teletext information is transmitted in the format of a header packet and a data packet. The header packet contains information identifying the teletext information according to page number as well as other filter fields, such as language, time zone, etc. By appropriate selection of the values of the filter fields, the operator is afforded greater flexibility in providing a variety of classes of service and service support to subscribers. In addition, the system may be easily be reconfigured to support the addition of services or the cancellation of services.

    摘要: A digital transmission system for transmitting, e.g., television sound has two packet type indicators indicating, e.g., mono/stereo transmission. Normally the same packet type indicator is transmitted for a long sequence of packets. To provide synchronizing information to enable, e.g., appropriate timing of a sound signal to the associated video signal, the packet type indicator for a single packet is changed to an indicator which is inappropriate to the packet concerned but is appropriate to another type of packet.

    摘要: A system broadcasts videotext data in the form of data packets originating from numerical data coming from several paths. Each packet has a prefix which contains synchronization and path identification code signals, a format signal which indicates the length of the data which follow the prefix. The transmitting station has as many coupling devices as there are paths for originating data. The coupling device has a data memory coupled to drive to a multiplexing circuit under the control of a common governing circuit. An inhibition order is given either as soon as the memory is full, or as soon as a counter has reached a pre-determined count. Then, the memory is connected to the multiplexing circuit, into which the stored data is emptied. The system is characterized in that a small capacity buffer is used between the memory and the input circuit for reading data out of the buffer memory responsive to a programmer. A transcoder treats the broadcast data to fit it into the system format.

    摘要: Disclosed is a process for the transmission of information over television networks wherein certain information is encoded in digital form and transmitted by supplementing and/or replacing the information forming the conventional program. The digital information is received by a conventional receiving set equipped with a decoding, memory and detector means. Information is transmitted in the form of analog signals subdivided into scans or groups of scans, each scan having associated identifying material. The information transmitted in digital form has other identifying material and is transmitted generally synchronously with the corresponding information in analog form. The transmissions are received by receivers with detectors sensitive to the identifying material and which have analog-digital and inverse conversion means as well as memory and decoding means to reproduce the information contained in the analog and digital signals.
