  • Patent number: 4977449
    Abstract: A broadband (RF) system using frequency agile demodulators or frequency agile modulators for coupling video cameras at remote locations to one or more video monitors at a central location. In a first embodiment, video cameras at remote locations are provided with respective modulators for coupling the outputs of the video cameras to a broadband coaxial or fiber-optic cable which couples all of the camera outputs to the input of a frequency agile demodulator at the central location. The output of the demodulator is coupled to one or more video monitors for display of the video signals from the remote cameras. The demodulator at the central location may be set to any camera channel manually or under processor control. Each video monitor can then view the video signals from any remote video camera by selecting the appropriate channel at the demodulator at the central location.

  • Patent number: 4943994
    Abstract: A still picture picturephone communication system for transmitting and receiving a still picture over a telephone circuit including a handshaking process wherein prior to still picture transmission, identification code data indicating a function of the picturephone set is transmitted and received, and a decision is made as to whether the still picture is being transmitted or not. A designation code of a desired response waiting time within an identification code data used at the time of handshaking is formed, and the response is delayed by a period of time corresponding to the response waiting time. A still picture data is directly transmitted and received without handshaking. In addition character data including character information and the like can be transmitted and received, and by manipulating the picturephone set of one party the picturephone set of the other party can be made to transmit picture data therefrom. Furthermore, the picture sent from the called party can be transferred to a third party.

  • Patent number: 4941040
    Abstract: A method of, and a system for, selectively delivering still television video with accompanying audio to home subscribers over a cable television system for advertising, promotional or educational purposes. A maximum number of home subscribers can interactively request presentations of their own choosing to be displayed on their home television sets. Only one standard television channel is required for transmission of still video with accompanying audio to serve 300 concurrent users. No equipment is required in the subscriber's home. The video is presented as still frames from one of a number of videodisc players, transmitted over one television channel during the appropriate time interval of 1/30th (or 1/25th) of a second. Such video frames, which may also contain overlaid graphics information, are uniquely addressed to a remote storage device. Unused bandwidth is used for the transmission of up to 300 discrete audio messages.

  • Patent number: 4941170
    Abstract: A facsimile transmission system is used to transmit documents over telephone lines using an electronic mail system, which may be a localized system or a distributed electronic mail system. Transmission is initiated by the sending facsimile machine transmitting a mark sense cover sheet, which has a mark sense identifier printed on it, to a facsimile controller. The controller checks for the presence of the mark sense identifier and if present, the controller reads the identifying information and destination address coded thereon. The controller then transmits the identifying information and destination address and the subsequently received document facsimile data to the electronic mail system in digital form, for retransmission back through the same or a different controller to one or more receiving facsimile machines.

  • Patent number: 4935953
    Abstract: A system for full motion videoconferencing. The total video image space is broken down into regions of such position and size relative to the space that the image data in predetermined sections of the regions is overlapped during the cyclic transmission thereof. The reception and display of the superimposed regions provides a significant increase in the perceived transmission rate in the overlapped sections, rendering those sections suitable for full motion effects.

  • Patent number: 4932047
    Abstract: An improved video phone transmits a source image over a standard telephone line in conjunction with voice signals. The unique initialization protocol provides a hardware preamble for synchronizing a receiver clock, a software preamble for identifying the video image and disabling the audio, automatic gain control adjustment data and amplitude calibration data. The audio portion is disabled by coupling a capacitor across the telephone to effectively short the telephone. The telephone is placed across a bridge circuit which is provided with switches to balance the bridge in both the telephone and video modes. The transmitted and received signals pass through the same delay equalization circuit, so that half the equalization is done before transmission, with the remaining half being done after reception. Input and output selectors allow the same circuit to be used. The digital signals are level shifted up prior to being converted into analog, and then are shifted down again to reduce the effects of DC offset.

  • Patent number: 4931865
    Abstract: This invention discloses apparatus and methods for monitoring the television viewing acts of individuals by transmitting a signal toward the individual and detecting the reflection of the signal from the individual's eyes to determine the time intervals and total times the individual is viewing the television. This viewing information is then correlated with the program information from the television. The apparatus and method of this invention can be used to identify each individual viewing the television and track and correlate the viewing information for each individual. The signals reflected from each individual's eyes can also be used to determine changes in blink rate and/or pupil dilation in order to determine the emotional response of each individual to the program being viewed. This invention also provides a system for monitoring the times at which particular programs are viewed by particular individuals even when the individual records the program on a VCR and views the program at a later time.
