Definitions
- This invention relates to an electronic display apparatus.
- Passive video displays such as produced by a videotape or videodisc player, are well known. It is also known to provide a videodisc player with an interactive display, the videodisc player being provided with a miroprocessor which is programmed with program data read from data dump areas from the videodisc. The microprocessor enables the videodisc player to operate in programmed sequences, so as to display information in a manner other than the sequence in which it is recorded on the disc.
- the Pioneer Level II and III videodisc systems are provided with a microprocessor in the videodisc drive unit.
- the present invention is concerned with the provision of an interactive display apparatus in which a display of information is controlled in dependence upon a user's reaction to the displayed information and which is capable of being embodied in a compact form.
- the present invention accordingly provides an electronic display apparatus comprising a microprocessor means arranged in response to signals obtained from a program store to supply command signals to a transcribing means, the transcribing means being responsive to the command signals to transcribe from a storage means selected video information signals for display by a display means.
- the apparatus of the invention has manual input means for controlling the operation of the microprocessor means.
- the microprocessor means is preferably arranged to supply to the display means video information signals from the program store. It is advantageous for the programming of the microprocessor means to be changed as may be required in a simple and convenient way. Such re-programming is independent of the videodisc information and is therefore preferably provided for by constituting the program store as replaceable storage device for example a floppy disc drive.
- the display means may comprise a common display device for the picture or video information signals derived from both the microprocessor means and the transcribing means, and there may be provided control means controlled by the microprocessor means for selectively applying the picture information signals from the microprocessor means and the transcribing means to the display means.
- control means may comprise a changeover switch for connecting display information signals either from the microprocessor means or from the transcribing means to the display means, or the control device may comprise means, for example, a mixer, for feeding the picture information signals from the two sources selectively and concurrently to the display means for concurrent display.
- the invention may be carried into effect using a conventional passive videodisc player as the transcribing means, and a conventional domestic microcomputer as the microprocessor means, each developing display information signals fed to a single display screen under the control of a switch means controlled by the microcomputer, so that the display screen displays data either from the microcomputer or from the disc player.
- the microcomputer also develops, as the command signals, signals which simulate those developed by the conventional hand held remote control unit for the disc player, to enable the microprocessor to control the picture information produced by the disc player.
- the disc player and the microcomputer can be linked together to provide an interactive display, which is readily portable, and is suitable for use as a promotional display.
- the apparatus according to the invention may also be constructed to employ a microprocessor embodied in a disc player.
- the microprocessor means in any event has a program store separate from the videodisc.
- Figure 1 is a schematic block diagram of a first display apparatus according to the invention.
- FIG. 2 is a schematic block diagram of a second display apparatus according to the invention.
- a microcomputer 1 and a videodisc player 2 are so arranged that one or the other supplies video signals to a display means in the form of a video monitor 3.
- the microcomputer 1 is a conventional device, for example an Acorn microcomputer model no. BBCB, which includes a keyboard 4 and a microprocessor. A floppy disc drive 5 is used to program the microcomputer.
- the videodisc player 2 is also a conventional device, for example a Pioneer Level I (domestic) disc player which transcribes data from a videodisc by means of a laser so as to produce, video signals on an output line 6.
- the microcomputer 1 is programmed to produce video signals on a line 7 and command signals on a line 8.
- the command signals are used to control operation of the videodisc player 2 and also to operate changeover means comprising a detector circuit 10 and a relay 11 whereby video signals are fed to the video monitor 3 either from the microcomputer 1 or from the video disc player 2.
- the videodisc player 2 has an input 9 for receiving signals from a remote control keypad, but in the illustrated apparatus, the keypad is not connected.
- the command signals from the microcomputer 1 instead simulate the keypad generated signals and are applied to the input 9, thereby permitting the microcomputer to control operation of the videodisc player 2.
- the command signals on line 8 are also applied to the detector circuit
- the detector circuit 10 which drives the relay 11.
- the detector circuit 10 is arranged to detect command signals of a particular amplitude frequency and/or shape characteristic and to respond to these to selectively control operation of the changeover contact of the relay 11.
- the microcomputer 1 controls the changeover contacts of the relay
- the command signals supplied by the microcomputer 1 to the input 9 of the videodisc player 2 control the player to transcribe video information from the videodisc on a frame by frame basis, so that individual still frames are selectively displayed on the monitor 3, or predetermined sequences of moving picture information may be displayed at normal speed or at some different speed.
- an interactive display of data can be provided on the video monitor 3, the display data being controlled by the microcomputer 1 in accordance with the program provided from the floppy disc drive 5.
- the microcomputer 1 may first cause the display of data on the monitor 3 via its output line 7, the data comprising a display of a set of questions to be answered by the user. The user responds to the questions by operation of keys of the keyboard 4.
- the microcomputer 1 then instructs the videodisc player to transcribe video signals for a particular frame of picture information, the frame being determined by the answer given by the user on the keyboard 4.
- the microcomputer 1 also feeds a signal to the detector circuit 10 to operate the relay 11 so that the video signals produced by the disc player 2 are fed via line 6 to the monitor 3.
- the display apparatus shown in Figure 1 may be used for marketing purposes for example in pharmaceutical marketing.
- the microcomputer 1 may then be programmed firstly to instruct the videodisc player 2 to transcribe video signals for display on the monitor 3 concerning a particular medical condition.
- the microcomputer 1 commands the relay 11 to switch over and connect the monitor 3 to receive video display signals from the microcomputer.
- the microcomputer generated display signals may comprise a question about the previously displayed sequence from the videodisc player 2.
- the user responds to the question via the keyboard 4. Further data may then be displayed on the video monitor 3 in dependence upon the response of the user. If the user's response to the question was correct the microcomputer displays on the monitor 3 information relating to proprietory pharmaceutical preparations appropriate to the medical condition previously displayed.
- the microcomputer 1 If the user answered the question incorrectly, the microcomputer 1 provides a video display indicating an incorrect answer and then gives the user a choice of repeating the display from the player 2 about the medical condition, or of changing to a display concerning other aspects of the medical condition.
- the microcomputer 1 appropriately commands the player 2 and the detector circuit 10 in dependence upon the user's response.
- the display apparatus thus enables a conventional videodisc player providing a passive display, to be controlled by means of a microcomputer to achieve an interactive display whereby display data is selected in accordance with responses from the user.
- the microcomputer 1 and disc player 2 produce video signals at the line frequency of the video monitor 3.
- the computer 1 and player 2 can be arranged to produce video signals modulated onto a UHF or VHF carrier in which case the video monitor 3 can be constituted by a conventional television receiver.
- the commands produced by the microcomputer 1 to the input 9 of the disc player 2 can simulate all of the standard functions of the player so that it can be instructed to play or search, and operate in slow or fast forward or reverse modes or still frame.
- the disc player 2 produces audio signals on two channels to provide stereo sound and the video monitor 3 includes an audio system with loudspeakers for sound reproduction in response to these audio signals.
- the audio signal channels can be selectively switched by means of the command signals on line 8.
- the disc player 2 may again transcribe data from a videodisc or may be a laser-red transcription device using discs of the format currently used for audio transcription.
- the microcomputer 1 of Figure 1 is replaced by a dedicated microprocessor 21 provided with a keypad 24 and a program memory 25.
- the program memory 25 may comprise a floppy disc and associated drive equivalent to the floppy disc drive 5 of Figure 1 or alternatively an interchangeable read only memory ROM.
- the microprocessor 21 produces video display data on line 7 and command signals on line 8.
- the command signals control operation of the disc player 2 are additionally control operation of a mixer 27.
- the mixer 27 enables video signals on line 6 from the disc player 2 and on line 7 from the microprocessor 21 to be applied to the video monitor 3 either individually or in a superimposed manner.
- the microprocessor 21 and video disc player 2 have their own internal clocks which define respective time bases for the video signals on line 6 and 7.
- a phase lock loop 29 is provided, utilising the phase of the video signals from the disc player 2 as a reference, to ensure phase synchronism between the disc player video signals and the microprocessor video signals, so as to permit them to be mixed by the mixer 27.
- the described embodiments of the invention have the advantage that the video data from the video disc player can be controlled independently of the sequence in which it is recorded on the videodisc. Moreover, further video data can be displayed from the microcomputer 21.
- the form and sequence of the display is controlled by preprogrammed information from the floppy disc drive 5 or the program memory 25 and thus can be controlled without the need to make reference to data from the video disc.
- the program for the microprocessor may be arranged to define, via the system clock of the microprocessor, a predetermined time period associated with each frame of displayed video information.
- the time for the number of frames associated with the sequence is calculated and the videodisc player 2 is commanded to operate for this calculated time.
- the microprocessor 21 instructs the videodisc player 2 to search for a particular frame of video data
- the microprocessor is programmed to assume a particular average time for access of the searched frame and to inhibit execution of any further programmed instructions during the time allocated for the search.
- the above described arrangement has the advantage that if it is desired to change the form or sequence of display, the program stored in the program memory 25 can be altered without reference to the stored data on the videodisc in the player 2.
- the microprocessor program can be updated while still using the same permanently recorded video data on the videodisc.
- the videodisc player 2 could be replaced by a videotape player.
- the video monitor 3 can be a conventional cathode ray tube device or a flat screen display.
