Abstract

Device for an automatic transmission method for video and audio signals via the conventional two-wire Deutsche Bundespost (NOT ISDN or NON-broadband) telephone network to a receiving station which uses this network.

Description

The said method has the purpose of image and sound signals from to transmit a quasi-transmitting station to a receiver. This can be a wide variety of image / sound types and Act content, depending on the desired application. On that However, the section "AREAS OF APPLICATION" is discussed in more detail become.

The transmitting station can be separated by individual components connected, all necessary functions of an automated Reach expiry. This would also be the case with a kind of compact device realizable, in which all individual components of the plant in a single, probably relatively small, device and are coordinated.

The components of the basic / basic version include:

• 1) Automatic pickup
• 2) Automatic switch to the required picture / sound source
• 3) Automatic frequency adjustment of the respective picture / sound source
• 4) Picture / sound source: (e.g. VIDEO REC, CAMERA, COMPUTER, IMAGE PLATE)
• 5) Automatic start device for the image source
• 6) Timer (device for presetting the transmission time)
• 7) Video telephone for operation on conventional, two-wire DBP telephone network

In addition to this basic version, it is also possible:

• 8) Computer program for various control options of the actual recipient
• 9) Acoustic control unit for implementing number ( 8 )
• 10) Automatic device for detection of a connection loss on the part of the recipient

Technical and functional process:
As mentioned, the transmission line in our process consists of the normal, two-wire telephone network of the Deutsche Bundespost (NOT the broadband network). An videophone device is connected to this, which harmonizes with this network (for example the XITEL currently offered by the DBP itself). The image signal of the camera originally used there is placed on an automatic switch, a kind of adapter, which enables the connection of other image / sound signal sources such as video recorders, computers, video discs and of course the camera etc.

At the beginning there is an automatic telephone pickup, which is technical works like the answering machine, d. H. when calling the transmitter the automatic responds by a recipient / consumer Buyer on the bell and sets independently the connection between the sender and the caller.

Furthermore, the transmitter with a preset timer and equipped with an automatic starter. For example, that comes Picture / sound signal from a video recorder or a video tape, can be set by timer, how long at the tape is to be played on a call or retrieval. After that the connection is broken, the tape is rewound and is for the next caller or caller ready for operation. The respective picture / sound signal device itself is controlled by an automatic Starting device after connecting is activated.

The most complex component of this system is the automatic one Frequency adjustment of the different picture / sound sources. Each transmitting device uses a different frequency. With a normal one TV set the associated frequency on the TV itself searched and set to receive picture / sound. This is here not possible because the videophones have no setting options to have. They are fixed to the frequency of the built-in camera, which normally provides the picture. So it is there the receiver is not aware of the frequency of other picture / sound sources can adapt the task or necessity of the transmitting station, the other signals to the original frequency of the bring built-in camera that the caller or retriever receive can. This is realized by an electronic component, which after a single manual adjustment to the respective sending device is fixed.

Expanding modules would be the automatic detection of a Disconnection on the part of the caller or caller (similar to the Principle of the answering machine) after the recognition itself the connection is interrupted and the sending station is in the initial position brings and provides for the next caller or caller. This would make the timer described above unnecessary.  

Another possible building block would be the provision of a Computer program, which various inputs or interventions on the part allow the caller. Here we think of a kind of control (e.g. selection option) various offered picture / sound information.

This, in turn, can only be achieved by an acoustic control unit be what inputs of the caller are recognizable for the Program passes on to this. Here we are thinking of an acoustic one Recognition device, which gives the caller the possibility of digits from 0-9 on his phone's normal dialing keypad to enter. The control unit recognizes the number from the noise. Entering a 1 z. B. creates a unique acoustic "Click" in the telephone network, a 5 a five-fold "click" etc. Our control unit is able to recognize them and to be requested as a corresponding number to the computer program Pass on processing.

Actual process:
A caller selects the transmitting station in order to call up picture / sound information offered by the transmitting station. He gets the number of this station from the corresponding publications / advertising etc. The transmitter responds to the ringing tone, answers automatically and establishes the connection to the caller. There is a switchover to the picture / sound source provided by the transmitting station and the corresponding automatic adaptation of the receiving frequency of the caller. Then the picture / sound signal transmitter is started automatically (e.g. video tape).

The caller now receives picture and sound from the one we have provided Picture / sound source on the screen of his videophone device sent. After the preset airtime has expired or after a recognized connection breakdown, the transmitter reset and is ready for the next call.

With the extended form (control via computer program) the caller, for example, a selection menu of various picture / sound information numbered, which he then over the Dialing keypad of his video telephone device according to his wish can retrieve.  

Possible applications:
In principle, any type of image / sound transmission is conceivable that can be implemented with the above-mentioned image / sound sources. However, the transmission speed of the image information is extremely slow compared to the broadband network (ISDN), so that (at least currently) the transmission of video films is hardly conceivable due to the immensely long transmission time. The DBP system regarding The normal, two-wire network therefore compresses itself on the transmission of static images and, when the images move, does not transmit the entire image but only the smallest possible sections that move and, for example, leaves the background that is not moving. This technical limitation (optimizations are hoped for) unfortunately limits the scope. However, to clarify the purpose of the transmitter station, we will show some technically feasible examples:

1) Example mail order companies

Various mail order companies broadcast on private television channels Permanent advertising programs such as TELESHOP from Otto Versand. There are different products shown, described and provided with an order number, the interested parties via a can order by phone. This process would also be achievable through our plant. The Shipping company publishes a phone number provided by customers can be called. There is a previously created video tape provided which products according to the same principle optically shows and also describes acoustically. On this tape can not only the (because of expensive airtime) mostly only 4 offered Articles are presented, but any number. The costs of the provider are limited to the one-time purchase of a transmitter and the creation of the product video tape, which is comparatively at airtime should only make up a fraction. The order is placed after the same principle, the caller gets e.g. after every 5 Offered a phone number called where he was after Call the advertising video and order if interested.

2) Example auction houses

An auction house creates a presentation video tape before an auction the item to be auctioned. This on one of ours Transmitting systems provided allow any owner of a Videophones to view these items before the auction and to be described. What positive progress for the auction house AND for the customer, who can now use color and sound can inform, instead of a meaningless, mostly black and white Holding (text) catalog in hands. A piece of the future.  

3) Example television program "File number XY unresolved"

Phantom images become more certain during each of these programs Gentlemen shown. Most of these are at the end of the show Repeatedly ask many callers to show them again. This is where the use of our system really comes in handy. The phantom images shown in the program are previously on a Video tape specially recorded and provided in the system. At the end of the show Eduard Zimmermann will say one day: "And for all owners of a videophone are below Number the phantom pictures of today's broadcast for another week available around the clock. . . " This example relates to a specific TV show, however, we are sure that there are multiple uses for television stations, various picture information via video phone to be made available in addition to the current program.

4) Example animal shelters

Here we lean on the principle of the TV show "A home for Animals ". There changing dogs and cats become animals and other animals presented, hoping for them a new one To find at home. Viewers of the show can be interested in an animal via a number displayed with the animal shelter Make contact. This system is also feasible through our system. An animal shelter creates a video tape of the animals that are happy to be conveyed would. This can be slow because of the already mentioned Transfer speed only uses static images be, but they are completely sufficient to unite a prospect to create a colored impression. So he has the opportunity get a picture before visiting an animal shelter. There would certainly be a chance here in advance of some things To arouse caller interest, and rather to visit the shelter to motivate than would otherwise be the case.

5) Example car dealerships / tuning companies / parts suppliers

Our system results in countless numbers, particularly in the automotive sector Possible uses. Car dealerships can go beyond a certain Video phone number, for example, a demo tape about their latest car model Make it available (compressed accordingly). An effective advertising medium with tiny acquisition and operating costs. Tuning companies could also benefit greatly from this. Man says that spoilers are equal to spoilers, but you can't get around, that every spoiler looks different. So have interested Customers have the opportunity to embellish these parts To be inspected in advance by videophone and see for yourself choose the tastiest part for yourself. This saves at least the time-consuming catalog order, should this does not even exist, it often saves a long one Drive on suspicion to the provider company. So providers in turn AND users of the system great advantage. The same system is of course also available for parts suppliers at. This therefore does not need to be explained any further become.  

6) Example agencies

Here we speak, for example, artist agencies, model agencies, Contact and matchmaking etc. In this industry it is necessary to represent people who, in in whatever way should / should be conveyed. This is most effective if, in addition to (as in newspapers, for example) text also published the picture can be made visible to the person. This is with ours System can be implemented easily. In addition to the color image shown the otherwise written text next to the photo can be acoustic be transmitted. The chances of a successful placement increase immensely in this way, and in turn have providers AND users great advantage of such a system. Here too we see a real piece of the future.

7) Example entertainment

When it comes to entertainment, our system of imagination is almost no limits. From picture puzzles for children to Strip poker game for adults are almost any form of Entertainment options can be realized and offered. Also, or just about the image / sound source used here a myriad of compressed tele-games adapted and provided become. An absolute piece of the future!

These 7 points now show various possible applications. We are certain that the range of these possibilities is only touched upon to have, however, think that it is understandable which innumerable, positive possibilities through our system for Providers and users would result.  

To the following drawing:
In the following drawing, the combination of the blocks and the logical sequence are made visible again.

The arrows show the to illustrate the logical sequence Direction on, over which the input signal the sending station activated and in which direction the signal then sent the Leaves the station to the receiver.

All of the listed modules would also be in a single, compact device conceivable, which is hardly larger than a normal one Video device should be. In this regard, we will submit a separate registration become.
