The present invention relates to an audio-visual dynamic interconnecting system for connecting at least one television set and various peripherals to a tape recorder, a series of VIDEO (video), satellite satellite.

Today we can not connect to a single peripheral device after a television set; the number of such peripherals is limited: electronic collectors, gauges, tape recorders, which are connected by radio frequency which is connected to an audio frequency.

* However, in the near future, the number of connected peripherals after the home TV will be significantly reduced as we will be able to have:

. special terminals for the new wired radio service, or. telecommunications intended for the general public and today called:

ANTIORRE: Radio-telephoned, integrated into the television signal, or broadcast over a full channel.

EPEOS: 'Service for automatic recording of the received programs.

DI3CRET: Television service intended for the deaf and dumb listeners.

One solution may be a system of cables and connectors placed manually, gradually as needed. They are a complex system, with little effect on the average listener, with little due diligence due to possible connection errors, so, in essence, a little realistic and destined to fail due to the complexity of its uses.

One refinement could be found in the use of a set of mechanical inverters ensuring the potential for interconnection combinations. * In such a system it is therefore heavy, complex and therefore also a little satisfactory.

Finally, an AV banding connector is automatically connected to the processing unit and the unit plates to the BD data balance, the decoded signals emitted by the processing unit, as well as to the specified specifications. unit plates.

Slow and fast switching (control) switches are also connected to the respective lines of the TV sets.

We will already describe in detail the functional structure of a CM1 unit plate, referred to in Figure 10, for the precise determination of the mode of operation.

For the PRT1 peripheral reception, the unit panel is connected to the corresponding peripheral device or, presumably, to the right of the figure. The analog information, either coming from (or intended for) the peripheral device, passes to the TV device (or comes from it) (or goes to another computer or comes from it) via the BAN analog balance, analog CAT scales of the BAD balance-controlled addresses, through the decoded DEC1 addresses, where the RA or unit plate address is programmed.

This decoded address attacks the BOM still memory at the request of the BD data balancer. * The memory then transmits its contents from the BDV, via the BD balance, to the automatic AV which makes it active for the purpose of displaying it on the TV set.

As it relates to the circulation of operating information on the exchange lines E and data D, it will be better understood by the simple reading of Figures 11 and 12. In Figure 11 (left (section)) the microprocessor is assumed ΜΡ έρωτα το περιφερειακόν δργανον Ρ1 διά της γραμτής ανταλλαγή Ε.

- 18 and, following this question, instructs the P2 peripheral via the data line D (right-hand section). * The transmission of this command is not disturbed, as the microprocessor gives, through the exchange line E, to the peripheral P1 only the power supply to transmit.

Figure 12 shows the intervention, on such exchanges, of the commands transmitted by the user through the sensitive instrument 08, which is thus attacked by the CT remote control keyboard. These devices go to the MP processing microscope, which includes a DEC decoder.

We have already described, by a simple example and with reference to Figure 7, a possible way of using the system according to the invention.

It is assumed that the installation which the user has consists of, in addition to the T7 TV set, also of the following peripherals:

A simple code corresponding to the operating position of a given peripheral body begins to be tapped on the CT remote control keypad. This command, transmitted to the micro-processing device via the TC remote control line, causes the contents of the corresponding ROM memory corresponding to the specified peripheral peripheral to be displayed on the TV screen of the TV set. the details of the operations to be performed in order to actually achieve the desired position in operation. It then performs these operations on the CT keyboard.

Appropriately interconnected by the peripherals, according to the TC remote control command transmitted, the 12 GHz P1 receiver image is transmitted to the TV set, while the other frequency is transmitted by P23 tape recorder · The P2 tape recorder, connected after the antenna, records at the same time another program or information camera image surveillance-. P5 is transmitted to the TV set via the EDI format (IMAGE DANS L'LMAGE₌ images within the image).

To ensure a certain simplicity of use of the remote control, the invention provides the use of special keys. (function keys, eg dg + or -) connected after the alpha numeric keys.

Thus in the selected example, the user acts sequentially on the VCR keys, decoding the received code signals to form the VCR code.

The keys, especially the keys themselves, emit a certain code in one case or another.

The system according to the invention allows any desired interconnection to be made between the peripherals, whether it is technically complex or such interconnection.

* It is enough for the user to give simple and short instructions, and then confirm them with detailed instructions, the complex of which is no longer obscure, as these instructions are automatically displayed on the TV device. No substantial handling of connectors and cables needs to be performed, as the connectors are made by means of electrical switches.

To this advantage of flexibility and ease of use is added a unit construction which allows for the subsequent addition of additional unit plates in the case of the acquisition of new peripherals.

It is understood that the invention is not limited to the examples described and that it would be possible to conceive of various secondary variants without departing from this scope. Thus, for example, the CM1, CM2 ... modules may not consist of circuits physically separate and mounted (respectively) of corresponding distinct cards, but of circuits naturally assembled on the same printed form. It then makes sense to declare these units under the more general definition of control floors. In such an embodiment, the decoding agents DEC1, DEC2, ... may then be concentrated in a single decoding circuit.
