Abstract
The invention is based on a communications terminal, in particular on a video telephone, for transmitting and receiving video and audio, which contains video recording means (2) and video reproduction means (1), it being possible to switch the video recording means (2) off by means of a flap (6). In order to use the transmission capacity of the communications terminal even when the flap (6) is closed, an image which exists in a video memory (3) is transmitted in this case. A changeover is automatically made to the video memory (3) by operation of the flap (6).
Description
J
D 95/002*Ar 2172419 Communications terminal The invention is based on a communications terminal for transmitting and receiving video and audio, which contains video recording means and video reproduction means, it being possible to switch the video recording means off.
Communications terminals of this type are known, for example as a video telephone or videophone. These make it possible for a user to converse electronically with another user over a relatively long distance. Images of the users are in this case transmitted in both directions at the same time.
A video telephone in which the recording means, in this case a camera, can be switched off by means of a flap is known from the Zeitmagazin [Time Magazine], No. 10, 3.3.1995, pages 24-27.
In this context, the term communications terminal also means other equipment which makes it possible to transmit video and audio in two directions for communication via a telecommunications system. Thus, for example, personal computers can be retrofitted with video recording means and video reproduction means so that it is possible, using said means, to transmit video and audio between their users.
The problem arises for a user of the communications terminal that he can be called at any time of day by a known or unknown person and this person sees the user and his private environment, possibly at an undesirable point in time.
The object of the invention is thus to develop the communications terminal in such a manner that a caller is prevented from having undesired views of the private environment of a user, without this limiting the transmission capacity and the use of a communications terminal.
The communications terminal is therefore equipped in a known manner with means using which the video recording means (camera) can be switched off, for example when a call arrives and the user does not automatically want transmissions to be permitted live. However, since the user is interested in continuous video ._o_ transmission an image ,of thc~ user, which is stored z_n the communications terminal., is t;.ransmitted ~~ccord~_ng t.o the invention, at least as long as the system is not switched to normal camera operat.iorw A stored :image can be tra.nsmitt:ed once or continuously, ~~r else arc ir~lag<= :'c.~quence car: be transmitted.
An advantagecu.zs development: o:~ the communications terminal comprises said ternuina~. .;c~nta~n ~ng a ~rideo memory in which images of a pl.urali t:y c:~f: peop~.e, for example of a family, a croup or of i.rud:ivi.dual members of sa_d group ar_e stored, and a user can look for a des:ir_ea~ image, which is intended to be transmittec:~ when a a:.a7 i. ar:rives, before booting up the communi:::at:ior:s term~~nai.
The communication: terminal carp also be operated in such a manner that ~~n :image from the r,~ideo memory is automatica~_ly transmitted wren the video recording means are switched off . A changeover to true v icxc>o recording means can then be made, as desir~yd, du.r.ing operation.
The communications ter:rnir~al, whs.ch i:~ used by a group of people, can be scat, for r=xample, such that. a standard image, for ex~~mple of this groui:.~, is t:rant;mitted first when a call arri~Tes. A user from this group can then change over to his pert>on<~l image, which i.s stored in the video memory, during operati on. ~llter_nat:i.vely, the communz_catvyons terminal can be equipped uaith speaker identificat;.ion means, which automat=icvall,~ change over to the image of the person spc:ak:inct. Thc~ commur:i.cations terminal can also be equipped wi th means for imaga-; processing, us:Lng which the articulation anc~ nuirnici:i:~g cf t~1-~.e user speaking are evaluated and are i.ncorporat:.ed unto t:.r~e image of= the video memory which is c:urrer:tly being tr.rnsmitt:ed.
2a The images which are stored in the video memory can be produced in an advantageous manner using the communications terminal. The video recording means which are provided on the equipment are used for this purpose, it being possible for the user to monitor the image on the associated monitor. The image can then be stored in the video memory by pressing a button, as desired.
The invention may be summarized as a communications terminal for transmitting and receiving video and audio, which comprises video recording means, video reproduction means, and a flap, wherein the video recording means can be switched off by closing the flap, wherein the communication terminal further comprises: video storage means in which video information is stored; a processor for connection to a telecommunication transmission system; a switch having an input switchable between an output of the video recording means and an output of the video storage means and having an output connected to the processor, the switch being connected to the flap such that upon clo:;ing of the flap an automatic switching of the switch input from the video recording means to the video storage means occurs; the processor, when the switch input is connected to the video recording means, transmitting video information from the video receiving means and, when the switch input is connected to the video storage means, transmitting vicleo information stored in the video storage means.
An advantageous refinement of the invention is explained.

in more detail with reference to the schematic figure.
The figure illustrates schematically a video telephone which contains a monitor 1 for video reproduction and a camera 2 for video recording. The video telephone makes it possible to communicate via a telecommunications transmission system between two remote users, video and audio being transmitted in both directions. The means for audio transmission correspond, for example, to a known telephone system and are not illustrated in the figure.
The video telephone also contains a video memory 3 and a processor 4, which is connected between the video memory 3 and the monitor 1 and via which the connection to the telecommunications transmission system NS is made. An image from the camera 2 or an image from the video memory 3 can be transmitted over the telecommunications transmission system NS, as desired, by means of the changeover switch 5.
A flap 6, which switches the camera 2 off when it is closed, is arranged on the camera 2. Closing the flap 6 automatically results in the switch 5 making a changeover to the video memory 3, which then transmits an image from the video memory 3 instead of the image from the camera 2.
The processor 4 can be used for widely different purposes, for example for controlling the changeover switch 5, for reading from the video memory 3, for speech identification or for image processing. Using it, it is also possible to record images of a person via the camera 2, and to store them in the video memory 3.
If required, the video memory 3 can store a relatively large set of images. This video memory 3 is, for example, a semiconductor memory or a hard disk. The images remain in the memory 3 even after the video telephone is switched off or in the event of a power failure.
