- Interactive control of the video server via the video telephone is also provided.
- this video server for the individual user is limited to one service, namely the playing of videos. Further support of the services supported by telecommunications systems, in particular the simultaneous use of several services by a videophone, is not possible.
- the present invention has for its object to provide a telecommunications system for the transmission of video or audio signals, which enables the users of telecommunications terminals connected to the telecommunications system with image display device, in particular video telephones, access to other services even when using a service To enable telecommunication system.
- the video signal generator of the telecommunications system according to the invention for the transmission of video and / or audio signals additionally generates at least one further video signal signal and transmits this at least one further video signal alternatively to or in combination with the one video signal to the telecommunication terminal.
- the video signal generator fades the at least one further video signal into the first video signal as a secondary picture.
- the combined video signal transmitted to the telecommunications terminal thus contains the first video signal as the main picture and the at least one further video signal as the secondary picture.
- the at least one further video signal contains user guidance information for programming performance features of the telecommunication system using the keyboard of the telecommunication terminal.
- Performance features include all user-specific or globally adjustable features of services that the telecommunications system makes available to the users of the telecommunications system but also to outsiders. In this way, the user of a telecommunications terminal with an image display device is given the function provided a system-specific system terminal that allows the system to be programmed.
- the at least one further video signal contains a selection menu in which keyboard codes are assigned to the menu fields.
- the at least one further video signal contains information about the status of the telecommunication system and / or telecommunication terminals connected to the telecommunication system. It is therefore possible to program the system without preventing access to other services.
- a so-called "chief secretary function" can be implemented for the telecommunication terminal, in which the secretary informs himself about the busy state of his telecommunication terminal upon acceptance of the call which is intended for another subscriber can.
- At least one video surveillance camera is provided, which generates the at least one further video signal.
- the telecommunications system receives the additional functionality of a monitoring system.
- the surveillance camera can also be connected directly to the telecommunication system, which feeds the surveillance images supplied by the surveillance camera directly to a telecommunication terminal connected to the telecommunication system.
- an e-mail interpreter which establishes the connection to an e-mail server, interprets the information of the e-mails and converts them into video signals and feeds them to the video signal generator.
- the user of the telecommunication terminal can thus read the e-mails intended for him on his image display device.
- Interpretation means the conversion of the e-mail information into image information that can be processed by the video signal generator.
- the at least one further video signal contains automatic signaling when receiving e-mails.
- a browser which establishes a connection to Internet or intranet pages, which interprets information from the Internet or intranet pages and feeds it to the video signal generator.
- the browser can also display a unique number in the places where an internet or intranet page contains references to other pages, so that the browser can navigate between the internet or intranet pages by entering numbers on the keyboard of the telecommunications terminal supported, so that the system provides the user of the telecommunications terminal with a full Internet or intranet browser.
- At least one video memory is provided for storing image information with a control device. Upon request from the video signal generator, the control unit feeds the stored image information to the video signal generator.
- the video memory can be provided in a local computer network connected to the telecommunications system via a network interface. This is particularly advantageous if large amounts of data have to be processed and if the storage media can be used in an existing computer network.

- Figure 2 an embodiment of a telecommunications system with a video signal generator and a plurality of video phones;
- Figure 4 a variant of a selection menu generated by the video signal generator of the telecommunications system
- FIG. 6 shows an embodiment of a “boss-secretary function” with a secondary image faded into the main image
- FIG. 7 an embodiment of a telecommunications system with monitoring function by a video camera connected to a LAN and
- telecommunications system 1 shows a telecommunications system 1 which has an interface 2 to a higher-level network, for example an analog or digital public (ISDN) network 5, but also higher-level internal networks (Local Area Network - LAN).
- a higher-level network for example an analog or digital public (ISDN) network 5, but also higher-level internal networks (Local Area Network - LAN).
- the telecommunication system 1 has an interface 4, to which a commercially available and system-independent tele- Communication terminal with image display device, in this case a videophone 3, can be connected.
- the interface 4 can be a corded interface or a radio interface.
- the audio and video signals are transmitted via the interface 4 between the video telephone 3 and the telecommunication system 1 with the aid of a data format and data protocol corresponding to the video telephone 3 and the type of interface.
- the videophone 3 has a telephone keypad 30, an image display device in the form of a screen 31 for displaying received video signals, a hearing and speaking device 33 and a video camera 34.
- a further display 32 for displaying short text information, control characters, symbols or the like can be provided become.
- the first and the second video signal it is possible to combine the first and the second video signal and to supply this combined video signal to the videophone.
- Such a combination of the video signals takes place by superimposing the video image transmitted by the second video signal into the video image transmitted by the first video signal in the form of a secondary picture.
- the technical realization of the overlay itself has been known for a long time from television technology, so that in this regard reference is made to already available methods and devices.
- the interface 2 shows a telecommunications system 1 to which, in addition to a first videophone 3a, other communication terminals, such as a second videophone 3b and an audio telephone 7, are also connected.
- the interface 2 enables access to a public (ISDN) network 8, via which a connection to other video telephones can be established.
- ISDN public
- LAN local area network
- the possibilities that a telecommunications system can offer the user of a commercial video telephone are considerably expanded, because the second video signal enables the telecommunications Communication system, to supply further video information to the video telephone even during the transmission of the first video signal.
- this also allows the combination of several services that are offered by the telecommunications system 1.
- FIGS. 3 and 4 each symbolically represent a video image which contains an operating menu which enables the user of the video telephone to set the performance features of a telecommunications system using the video telephone keypad 30 according to FIG. 1.
- the main advantage is to make the videophone available for other services even while programming the telecommunication system. Incoming calls, e-mails, etc., for example, can be signaled in a secondary image on the screen 31 of the video telephone.
- Entry into such an operating menu generated by the video signal generator 10 according to FIG. 1 is preferably carried out by selecting a predetermined code number or special key on the video telephone keypad 30.
- the special keys "*" and "#" which are usually provided today are particularly suitable for this purpose, possibly in combination with others Keys. Often there are other special keys on modern video telephones that can be assigned accordingly.
- the telecommunications system establishes a switching connection to the video telephone, which usually contains a signaling channel for exchanging signaling information and a user channel in which the user data, in this case the audio and video signals, are transmitted.
- the individual menu items 310 can be displayed as text lines including a selection number 301 or an input field on the screen 31 of the video telephone.
- the selection of the represented Menu items 310 or an entry in an input field takes place by dialing the corresponding numbers or number combinations of the video telephone keypad.
- the telecommunication system can use the second video signal to show the user of the video telephone the status, in particular the busy state, of further video telephones or audio telephones connected to the telecommunications system in the conversation state of the one video telephone.
- the display of the status of interfaces to other telecommunications networks such as the network interface or the interface to the public network is also provided.
- a so-called "boss-secretary function" for a videophone 3 can be supported.
- a secretary can make a call for her boss on her videophone accepted, the status of the headset, which can be a videophone or an audio phone, is displayed optically on the screen 31. The status is displayed either at the request of the user of the video phone by selecting a key on the keyboard or automatically.
- the automatic overlay is particularly useful when a video call is transferred to a videophone in which only audio signals are transmitted and the screen 31 is not required for the call.
- the video signal generator of the telecommunications system can convert the audio call into a video telephony call, the audio information of this call originating from the audio call and the representation of the status being inserted as image information.
- the entire screen can be used for the display as shown in FIG. 5, the video signal of the telephone call being briefly interrupted, the video signal being faded in with the menu, and the video signal of the telephone call being subsequently transmitted again. It can be expedient to display the status of all telecommunications terminals in a department, group or even the entire company, from which a person can then be selected whose device is not manned.
- FIG. 6 shows an automatic display of the information about the busy state of another video telephone or audio telephone as an "on-screen display" in the form of a small secondary image 320 next to the main image 324 on the screen 31 of the video telephone.
- the size and position of the superimposed sub-picture 320 is chosen so that it covers only small parts of the main picture 324 and interferes as little as possible with the conversation.
- Another application of this automatic overlay is to signal the so-called "waiting" of another caller not only acoustically by means of a waiting tone, but also visually.
- the video signal generator generates a video signal for the videophone, which contains an displayed call number of the caller and any other information available about the caller.
- the telecommunication system according to the invention also offers the possibility of providing other information which is useful for the user of the video telephone in the form of image information.
- the duration of the call and the telephone costs accrued so far either as a number or as a graphic, e.g. in the form of a progress bar.
- a telephone book function can be provided which informs the user of the video telephone via internal or external telephone numbers. The number is selected by selecting it on the screen as described above.
- FIGS. 7 and 8 show a telecommunications system 1 that supports security functions, in particular monitoring functions.
- the simplest possibility consists in establishing a connection to the surveillance camera 12 for the users of video telephones 3, which can be connected directly to the telecommunication system 1 according to FIG. 7 via a LAN 5 or according to FIG.
- the video signal generator 10 can be used to display a plurality of images from different surveillance cameras 12 side by side on the screen 31 of the video telephone 3.
- the image of a surveillance camera 12 can also be represented as a main image, that of other surveillance cameras as a secondary image. It is particularly advantageous if the main image is provided cyclically by the various monitoring images.
- the display of a surveillance image as a secondary image also opens up, while another application, for example a video telephone conversation, supplies the main image. In this way, the videophone 3 receives the function of a monitoring terminal with which it is also possible to monitor generously, but other functions are possible in parallel.
- cameras and microphones are installed in the security-relevant areas.
- Such a monitoring function with the help of the telecommunications system can also be used in a hospital or old people's home to monitor the patients.
- the image supplied by a surveillance camera is fed from the telecommunications system to a videophone and enables the doctor or nursing staff to intervene quickly in the event of an emergency.
- An expanded monitoring option for users of video telephones is that the telecommunications system can either use a combination of several monitoring signals on a videophone or cyclically switches the video signals from various surveillance cameras to the videophone.
- Another security-relevant application of a telecommunications system is in a video door intercom. This can be implemented by connecting a camera to the telecommunications system via the S Q -BUS. By pressing the bell button, a predetermined videophone is dialed by the telecommunications system. As soon as the user accepts the call, he sees the visitor on the screen and can then communicate with the visitor via the audio channel using the telephone handset. The image display increases the security of opening the door to unwanted visitors.
- the telecommunication system can also be used to provide received e-mails as video signals for the video telephone.
- the request for such a service is again made by selecting a predetermined key on the keyboard.
- the video signal generator of the telecommunication system then first generates an overview menu of the e-mails received for the video telephone, the menu items being selected in the manner described above.
- the selection of an e-mail via the keyboard leads to the corresponding e-mail being displayed as picture content on the picture telephone.
- the user can then delete the e-mail, switch back to the overview menu or perform other actions by selecting fixed digits or special characters.
- Incoming e-mails can also be signaled automatically. This can be done by the overlay a secondary picture or a treadmill that runs up or down the screen. Additional signaling by an audio signal can be useful when it comes to important messages.
- the recipient's e-mail address is entered or selected from a selection list. Since the input of texts via a telephone keypad would be too expensive, the sending of audio and / or video e-mails is provided, which is recorded via the telephone, temporarily stored in the telecommunications system and then sent.
- the invention offers the possibility of displaying these pages as picture content on the video telephone.
- the prerequisite for this is that the telecommunication system contains a browser that is able to interpret the HTML format or other formats, i.e. to convert into information that can be processed by the video signal generator. This feature can again be requested by selecting a button.
- the browser After establishing a connection between the telecommunication system and the videophone, the browser fetches a predefined Internet or intranet page, passes it in an interpreted form to the video signal generator, which converts it into video signals and transmits it to the videophone.
- the telecommunications system automatically shows numbers in the picture. By dialing such a number, the user of the videophone can reach the display of the page to which reference is made. A navigation through the In this way, the Internet can be implemented, with the browser automatically displaying numbers in the image to support navigation when referring to other HTML documents, which can then be dialed using the video telephone.
- the telecommunication system can be used by a language school for unusual languages, in which the participants cannot be expected to take part in courses physically due to the long travel distance or a physical disability.
- the participants must be connected to the public network with an ISDN connection and equipped with a videophone.
- the language school calls the participants and a video conference call is set up.
- the language teacher can use the video signal generator to display additional video signals, for example the spelling of vocabulary, from a computer-assisted control terminal as a secondary picture.
- the language teacher can also provide the participants with prepared exercise videos or interactive computer applications.
- the application is equipped with a speech recognition algorithm that evaluates the pronunciation of the participants.
- this application can of course also be used for distance learning or distance learning for children in remote areas.
- Deaf people who are connected to the public network via a videophone can also make telephoning with non-deaf people significantly easier with the help of the telecommunications system. If the non-deaf also has a videophone, the video signal generator can automatically fade in the words spoken by the call participant as text in a further improvement of the speech recognition programs. The deaf can see the person they are talking to and at the same time capture their words through the text.
