DE4203021A1 - Decentral audio and video facsimile generation procedure - transmitting reproducible contributions via radio or TV network outside normal transmission time - Google Patents

Abstract

The decentral and time independent generation of audio or video facsimiles are intended for groups of interested subscribers. The contributions to be reproduced are transmitted via radio or TV broadcasting outside the normal transmission time by agreed group characteristic signals accompanying programmes. Only the video recorder stations of the authorised subscriber group receive automatically the transition at the same time. Pref. the allocation of the group characteristic signals, e.g. similarity with time announcement, causes the programme, transmitted within normal transmit time period, to be received by each suitable video recorder automatically. USE/ADVANTAGE - For education system using satellite transmission, with time programmed transmissions available at any time from copies.

Description

In countries like Brazil, education and training are dependent on many factors Education system very much from broadcasts distributed via satellite supported.

Because of the different times - 5 in number - there are serious ones Problems, e.g. B. Children have to go to school in the morning to be on To be able to take lessons in front of the screen.

On the other hand, the parenting problems prove expensive broadband during the day Satellite capacity used for other profitable purposes could.

It is an object of the invention to provide a solution to the above Solves time dependency problems. The solution is based on that in Europe distributed video program Servis VPS in TV broadcasting and on Radio Data System RDS according to EBU specification 3244-E, command PIN program identification Number, on the radio.

The object is achieved according to the invention by a system with a service character According to the main claim, particularly advantageous further developments result from the Subclaims.

With this system, the training fees are broadcast at any time. Like the VPS, these programs are accompanied by key figures that serve the purpose have all VCRs on and off that have these metrics have set.

The method according to the invention provides that in every school VCR is located, which is always ready to record. The recorder was with an agreed educational key figure, e.g. B. 4010, once on site set or its decoder was permanently set with this code delivered.

The educational key figure can be divided into groups, the spatial Facts of the educational institutions are adapted, u. B.

4011 1-4 great
4012 high school
4013 distance learning university
etc.

After the broadcast, this will result in the corresponding educational institutions automatically the correct audio or video copies. These facsimiles can then can be played any number of times.

The task of exemption from time dependency has been solved.  

Since the system with the application of education alone is hardly used and a z. B. 4-digit code contains 10,000 addresses, it is advisable to integrate further sub-services.

The extension of this service to health care is proposed.

The procurement of the originals to be broadcast for educational and Health care is primarily the responsibility of the authorities. These authorities hit one Selection from the contributions available on the world market or leave special Produce originals for this service.

Internationally operating institutions such as WHO, UN, churches, Development Aid Organization u. a. could in this way be central for the worldwide improvement of education u. Healthcare. So could reproduce important current information such as B. AIDS Combat, arise overnight at all doctors and high schools in the world.

Reserving health care metrics could include:

5020 hospitals
5030 doctors
5040 veterinarians
5050 pharmacology
5060 universities
etc.

Other conceivable applications in public and municipal areas are:

7010 military
7020 Disaster Service
7030 police
7040 environmental protection
7050 secret service

In these applications, even the broadcast of amateur footage could be broadcast Be interested when it comes to the rapid dissemination of visual information arrives e.g. B. in the fight against crime.

Occupational sub-services: Since the service according to the invention groups of Appeals to interested parties, it also makes sense to introduce occupational indicators, such as B.:z. B.

6410 architects
6420 biologists
6430 chemist
6440 tour operators
6450 politicians
6460 fashion designer
6470 musicians
6480 artists
6490 press
6500 sport
6510 video rental

A subscriber sub-service would be available for this job-related application own. Professional chambers or agencies to be established take care of the selection of productions available on the world market for the professional group of May be interested, or have special produce.

Examples

• - An agent produces excerpts from the Hanover Fair, especially for the Tailored to the needs of chemists, mechanical engineers, etc. and leaves them broadcast worldwide via video fax. The subscribers are thus over audio or Video resources updated continuously without having to travel.  
• - A tour operator describes a new route on video and offers it via videofax to travel agencies. These can receive the received video fax present it to the interested tourist. Confidential information how commission amount can be gained via text overlay if necessary - see Claim 4 -. The subscriber gets a valuable tool at work to practice his profession.
• - Filmmakers offer video rental retailers samples of the latest Productions not via the visit route, but across the country Video fax. Based on the samples, the rental companies decide which films include them in the program.
• - An architect publishing house offers its subscribers in addition to the magazine also the video fax service.

Videofax + Vido program service: according to claim 2, the private Service VPS or similar, also best integrated into the inventive solution by reserving the key figures 0000 to 2400, which look like times. This is another attraction for broadcasters and industry given.

Video fax in VPS: during normal broadcasting, there are also articles that be of interest to architects, lawyers, doctors, scientists, etc. can. Claim 3 provides that groups of interest also these Can receive contributions as Viedofax / Audiofax.

Example: the architects' video recorders switch on at Code 1410 as 6410.

Text overlay: Claim 4 describes another tool for applications to be able to operate that would otherwise require cumbersome image encryption.

Example: video transmission for horse racing betting shops. Protective measures are necessary to ensure that the offices pay the fees accordingly. As the most important information for Betting agencies is not the course of the race, but the profit table, the Transfer table according to the program and only on site licensed offices.

Protective Measures: Claims 5th, 6th and 7th record ways to help abuse the fee-based sub-services integrated here prevent. Because the transmissions are actually recorded by every recorder can be, the irregular transmission acc. Claim 5. the the simplest solution to protection. It can be assumed that a Users will not program continuous nighttime shots, only for fees of z. B. to save 30, - a month.

Another way of protection, acc. Claim 6, is the irregular Change the group key figure, e.g. B. from a selection of 5 options. The Changes will only be communicated to the authorized subscriber. The audio or Video recorders must offer a corresponding possibility to change the code to be able to.  

An attractive variant of the protection is gem. Claim 7. the addition of a individual key figure in the system so that it becomes possible to each one To activate or deactivate the decoder. This performance is in FM radio the individual responsiveness already with the service RDS-PAGING acc. EBU- Specification 3244-E. Realized. RDS-PAGING contains a 6-digit number Code number that guarantees the addressability of 1,000,000 recipients.

A videofax-specific solution to individual addressability is without further possible. By introducing RDS-PAGING, as later in Claims 11 and 12 shown arise for the video variant of the claim 7. possibly a cheaper solution.

Removal of the text display: Claim 8 means another non- public application for the service according to the invention, which otherwise one Encryption of the picture is required.

Example: fee-based video transmissions in the hotel room. Through the open transmission of the image, the interest of the guest can indeed be aroused by overlaying text throughout Screen surface acc. Claim 7, the enjoyment is very strong disturbed. There is reason to deactivate the display for To apply for room unit.

Tone coding: Claim 9 records with the coding of the sound signal another possibility to realize closed TV application. Withdrawal the audio information in a TV program is sufficient to enable a TV Deny viewers the enjoyment. This idea of the same inventor was already there registered with P 39 40 767.5.

Channel accompanying the program: Claims 10th, 11th and 12th stand for three of many possibilities of the mentioned program accompanying transmissions. Claim 10 records the variant as used in the VPS. Because the needed Data containing no color information will only be two worldwide Variants of video fax systems required: one for countries with a 525 line System, one for countries with a 625 line system.

Claim 11 shows a new aspect, namely the accompanying program Transmission of the digital information in the same medium as the stereo sound transmits. Z offers the possibility of this. B. the NICAM 728 system, which in England and is common to the Scandinavian countries.

The NICAM 728 carrier is placed next to the conventional sound carrier. NICAM contains a service channel that is used for the transmission of key figures and texts, possibly coded according to the RDS system.

With this solution, the aforementioned dependency on the national Number of lines. Only the subcarrier frequency varies.

Claim 12 speaks another possibility of accompanying the program Data transmission, the exploitation of Fukinuki Lochs. This option is interesting for countries that are all invisible Have occupied picture lines and have already introduced a 2-carrier stereo system have that hinders the accommodation of the aforementioned subcarrier.  

Claims 13 and 14 are other applications that make the System increase. Claim 13, the remote controlled shutdown of radio Devices is an advertising effect.

Claim 14 solves internal synchronization problems of broadcast networks.

Credit card block list: Claim 15. records another application of program-accompanying data transmission of great importance. In connection with claim 11. B., the solution can look like this: in the second The audio channel of the NICAM system becomes the complete program simulating once a day List of credit cards to be blocked or the like with a speed of over 300 kbit / sec. transfer. For the daily update of those to be blocked Cards, e.g. B. one per 5 minutes, is the speed of the program Channel, which may be operated with RDS, sufficient.

In credit card acceptance points, e.g. B. Restaurants are special Broadcasters who record this data and, if necessary, with the data compare customer cards. With this inventive application it is possible, within a few minutes, the most current worldwide Realize credit card protection.

Fax multi-address: Claim 16. relates to an integration of the Fax service in this service. This integration is particularly advantageous for offices, the news in paper form to a larger group of interested parties want to send.

Claim 17. relates to a recurring transmission of program Key figures instead of sending out program start and program end key figures. This can prevent the decoder from receiving signals when reception is poor missed. According to the invention, the receiver contains a hold circuit, which Gaps bridged.

Claim 18 fulfills the wish of households to be able to hide the advertising.
