专利汇可以提供Computer-assisted instruction via video telephone专利检索，专利查询，专利分析的服务。并且A teaching system utilizing a video telephone as a terminal in which the video telephone is tied into a computer whereby information is fed into the video telephone and other information is returned to the computer. A video tape recorder, containing a central bank of pre-recorded reels of video tape, is connected to the central processing unit of the computer and the video telephone whereby pictorial representations as distinguished from the alpha-numerical representations will appear on the screen of the video telephone enabling interaction with the student. This central bank of pre-recorded reels of video tape is connected to a buffer unit so that selected tape reels can be transfer recorded into the buffer unit where it is played back to the student selecting such tape. In this manner, the pre-recorded reels of video tape in the central bank will be available almost simultaneously to a large number of students at different terminal units in the teaching system.，下面是Computer-assisted instruction via video telephone专利的具体信息内容。
1. A teaching system comprising: a. a central video information storage medium of the type adapted for sequenced visual presentation of instructional information upon progressive sensing of said medium; b. a central electronic data processing machine connected to said central video information storage medium and having said instructional information programmed into said machine, said data processing machine including control and logic portions for determining which instructional information is to be presented in accordance with the program and the response sent to the machine by a user; c. at least one video telephone having a viewing screen thereon for the reception of said instructional information from said electronic data processing machine via said central video information storage medium, and including control means operatively connected to said video telephone permitting a user to send responses back to the electronic data processing machine; and d. a transmission means between said video telephone and said electronic data processing machine whereby signals can be sent between the video telephone and the machine; whereby responses sent by the control means of said video telephone to said data processing machine are used to determine which instructional information on said central video information storage medium is to be presented to the user.
2. A teaching system as described in claim 1, also including a control receiver unit operatively connected to said elEctronic data processing machine and said central video information storage medium for controlling the sending and reception of signals, and for translating the information sent from said data processing machine and said central video information storage medium into audio and visual signals delivered to the video telephone.
3. A teaching system as described in claim 1, in which said video telephone control means comprises a control panel operatively connected to said video telephone including buttons on said panel permitting a user to send responses back to the electronic data processing machine.
4. A teaching system as described in claim 1, wherein said central video information storage medium comprises a video tape recorder means operatively connected to respond to control signals from said electronic data processing machine so as to send pictorial and audio signals via said transmission means to said video telephone.
5. A teaching system as described in claim 4, in which said video tape recorder means comprises a central bank of pre-recorded reels of video tape connected to a buffer unit for transfer recording the audio and visual information from selected ones of said video tapes into said buffer unit, thereby permitting the pre-recorded reels in the central bank to be made available almost simultaneously to a large number of users.
6. A teaching system as described in claim 5, wherein said buffer unit includes a plurality of video tape reels for providing audio and visual information individually to a plurality of said video telephones, said central bank being activated to record information on one of said buffer reels in response to a control signal from the data processing machine indicating more than one demand for a particular pre-recorded reel.
7. A teaching system as described in claim 5, wherein said video tape recorder means includes reels or pre-recorded video tape in which a portion of the digital computer process control and answer signals are recorded on the same or adjacent tracks as the audio-visual (lesson) information.
8. A teaching system comprising: a public telephone system including multiple transmission paths interconnecting a multiplicity of student subscriber stations and a central station, the paths having the capability of transmitting at frequency bandwidths sufficiently wide to transmit video pictures and audio signals adequate to produce acceptable pictures and accompanying voice communication via video telephone; an electronic data processing machine at the central station programmed with various educational programs to be received in alpha-numeric form and audio and video form by any one of the following video telephones upon selection by a student subscriber of the video telephone; an interface receiver between said data processing machine and the following video telephones for translating the information of the data processing machine into audio and video signals to be relayed to the following video telephones; and a plurality of such student subscriber stations having terminal units each including: a video telephone; means for selecting an educational program at the central station; and means for submitting questions to the central station for receiving answers therefrom.
9. A system as in claim 8 in which the data processing station includes means for recording on a medium, such as tape, at said bandwidths, video-audio signals of educational programs for transmission to the video telephones of the student subscriber stations; and means for causing the data processing machine to actuate the recording means to direct its video-audio signals to the video telephones; whereby the information storage capability of the data processing machine may be minimized.
10. A system as in claim 9 including: branching means for the recording means.
