Fig. 7 and 8 show the practical use of the method and system in accordance with the present invention in the form of a generalized schema.

In Fig. 1 shows a variant of a communication system in accordance with the present invention, containing the node 1, the transmitting full signal containing audio and/or video information, in the form of a conventional analog radio or television signal, which is assumed to be near custom installations 2, of which the drawing shows only one.

In the described embodiment, the main components of the parts of alausa information a limited number of alphanumeric characters generated encoded as a sequence of signals of relatively short duration, consists of a number of simple sound signals representing individual characters of a message, the device 4 to add or write the message control information, initiated by the encoder control information 3 full signal representing audio and/or video information containing parts of the signal, as shown by the arrow 4A, obtained from other sources, not shown in the drawing, in addition to the encoder control information 3, and the transmitter 5 to transmit complete signal containing the message control information.

Accordingly, the installation user 2 comprises a receiver 6 for receiving full signal transmitted by node 1, the device search control information and the decoder 7 to extract the control information, bearing a series of beeps from the full signal received by the receiver 6, and a decoding this sequence in the original message management alphanumeric information, included in the full signal at the node 1, the data processor 9, and p is which actions initiated in response to the message control information received from the host 1, as part of the transferred full signal carrying audio or video information.

Fig. 2 shows the basic elements and illustrates the data processing and signal generator control information and the encoder 3 in node 1.

Message alphanumeric control information 5 is usually formed of a personal computer 10 managed by specialized software to generate a message that can be included in the full signal representing audio and/or video information and again extracted from this signal.

Part of the message control information, carrying important information, is entered from the keyboard of the personal computer 10 in the form of a sequence of a limited number of characters, usually from 10 to 150 characters.

The resulting message alphanumeric control information is further encoded character by character in a series of simple sounds, which can be composed of a single pure tones of different frequencies representing individual characters that can be used as the management information, the. Such single or dual tone signals can be read in digital form with the help of specialized programs from table 11 that preserves all possible single or dual tone signals to separate the encoded characters that are addressed by the address generator 11A, managed alphanumeric information entered from the keyboard of the computer 10.

Digital representations read from table 11 control the tone generator frequency 12 generating single or dual voice frequency signals of different frequencies, which constitute a separate message signs alphanumeric control information. Blips representing individual characters, are fed to the device Assembly 13, in which the signal indicating the beginning and the signal indicating the end of transmission is added to the beginning and end of the sequence of signals carrying information, respectively, and collected together to form a sequence of sound signals, which in this embodiment is the message control information, which is included in the full signal transmitted by node 1.

In Fig. 4 and 5 show typical coding or schema conversions is estwenno. The table on the drawings show a separate sound frequencies assigned to the numeric characters (digits) from 1 to 0, and the above-described indicator signals the beginning and end of transmission and the signal indicating the recurrence described below for single tone (Fig.1) and dual tone (Fig.5), in which the individual sound signals are a combination of the low tone frequency high tone frequency.

In the described embodiment of the method and system of the present invention, where the message control information may be the usual way included in radio and television programmes and the message control information usually appears on the installation location of the user as a sequence of short audible sound signals. To ensure a short response time and to avoid possible inconvenience, an important feature of the invention becomes, therefore, that the transmission of control information occupies a relatively short time, preferably less than 5 seconds.

On the other hand, a separate single or dual tone signals generated by the sound generator 12 should be of sufficient duration to allow without interference to be found in use is preferably has a duration of from 30 to 150 milliseconds and for practical purposes, the most appropriate is a duration of 85 milliseconds.

The indicator signals the beginning and end of transmission, introduced in the part of control information, carrier information, must clearly be different from the tone representing individual characters of alphanumeric information. This difference can be easily achieved in a simple way, by assigning these signals indicate the frequency that is significantly different from the frequency of the sign representing the tone signals and/or duration, which is much longer than the duration of the last. The preferred duration of the signal indication is in the range from 200 to 600 milliseconds when choosing 450 milliseconds as the most suitable value for practical purposes.

Thus, within the recommended maximum duration of 5 seconds may be formed from the message control information, which in addition to the signals indicating the beginning and end of transmission may contain from 10 to 150 individual characters.

To avoid confusion, when the same characters repeated several times in a continuous stretch of sequence signals General message control information, it is preferable that the tonal signal representing such a recurring character in each is repeated signal indication, which can be single or dual-tone signal with a frequency different from any frequency assigned to this sign, representing the signals, but the same duration, as these signals.

In Fig. 6 graphically shows an example of a sequence of audio signals as they are generated by the generator control information and the encoder 3, by generating single character representing the tone signals in accordance with the scheme of single tones, shown in Fig. 4 and represents a very simple message control information is composed entirely of digits "011123448911". The indicator signals the start, end and repeat transmission is indicated as S, E and R respectively. It is clear that the full sequence of beeps will be the nature of sound a short beep in this example with a duration of approximately two seconds.

In order to ensure that the detected transmission error in the installation user, it may be desirable to add a relatively simple parameter validation to the transmitted signal sequence control information. In the above described case is composed of otdelnyh digits of numerical messages in a single figure, which can, in principle, be encoded in a tone the same way as the real characters of the message control information. To distinguish the tone parameter validation from the mark representing the tone signals, the latter can be assigned to a predefined location within the sequence of signals, for example, as the first tone signal after the signal indicator of the beginning or, as shown in the example in Fig. 6, where the parameter V validate calculated in accordance with the above summation, as the last tone before the indication of the end of the sequence of signals.

In Fig. 3 the device search message control information and the encoder 7 of the installation user 2 shown in Fig.1, shown in more detail. Full signal transmitted from node 1 and received by the receiver 6 in the user, is applied to the detector 14 indicate the beginning and end of the signal. Once detected, the indicator of the start of transmission of the next sequence is fed to the Gating scheme 15, in which the received audio signal components are converted into digital signals PCM (pulse-Kodo the PCM from the Gating circuit 15 are processed in the device 16 fast Fourier transform (FFT) is fed to the spectrum analyzer frequency 17, detecting the frequency of individual elements of discrete signal sequence, forming a single character initial alphanumeric message control information issued by the host 1. The flow of data from a spectrum analyzer frequency is supplied to the assembler messages 18 that form the original message.

The sequence output from the analyzer frequency 17 also includes a parameter validation, served in the unit 19 to perform the operation confirmation of the correctness of the individual characters of the sequence data for the calculation of parameter validation in accordance with the same method of calculation, which is used in the maintenance host 1, and to compare this estimated parameter validation parameter validation passed node as part of the message control information. This comparison is performed after detection of the signal of end of transmission detector 14.

Only when the result is positive, validate the device 19 assembled message control information is transmitted to the data processor 8 computational ustanova information and decoder 3 in node 1 and all devices 14-19 search control information and the decoder 7 installation user 2 can be provided with software for personal computer so that these devices will usually appear as a separate structural components of the system of the present invention.

In the described embodiment, the message control information in the form of a sequence of sound signals can be used a personal computer equipped with a sound card. In the maintenance host sound card will serve as a sound generator 12, and the user 2 sound card performs the functions of the detector and discriminator 14 and 15, respectively.

In the above-described method and system, and when the message control information included in the transmitted radio or television signal, the message control information will be received and processed by the listener or viewer with a personal computer with a sound card and special software needed to perform the functions of the devices 14-19, search control information and the decoder 7 in the installation user 2.

In accordance with another important development of the method and system of the present invention, it is also possible to transmit the message control information in the transmission, aimed at defined

To this end, the device search control information and the decoder 7 installation, user 2, as shown in Fig.3, may include a memory block 20 with the stored personal information relating to the actual user, such as address, date of birth, gender, occupation, etc., that identifies a user belonging to any particular group. This address is stored in the node service to the message control information is directed only to members of this particular group. This information is then added to the message control information, originally formed in the personal computer 10, and this address information includes at least one parameter characteristic of a specific group of users.

In Fig. 7 shows an example of application of the method and the system for the case of satellite transmission of television program, as mentioned above. This television program may be a conventional television entertainment shows or educational or business program, but the possibilities of application of the invention can be varied and is in no way limited to only these types of programs.

From the device 22 television signals are transmitted on terrestrial broadcasting satellite station, is symbolically shown by the parabola 23, from which the signals in the usual way are transmitted to an orbiting satellite 24, relay the signals to the ground system of the user, as symbolically shown by the parabola 25. From ground stations television signals are transmitted over a cable network to a television receiver 28 connected to the installing user.

As mentioned in the description of option the message transmission control information in the form of a sequence of sound signals, the installation of the user may include a personal computer, equipped with sound cards. The audio portion of a television signal can be entered into the user's computer 27 or by using so-called SCART-cable that connects the computational setup with the TV or, as shown in the drawing, from the speaker system of the television receiver through the microphone 28, which is connected with a conventional microphone input of your computer sound card.

The example shown in Fig. 7, in which the message control information is inserted in the transmitted television signal, nimet television program signal, entered in the message control information recorded in the usual way on the magnetic tape, which can be used either for transmission or can simply be bought or taken for viewing by users. It is clear that on the user side, you can also connect the TV to the device the records in order to perform an initial program entry, including control information, and to execute playback of the program, including communication control information at a later time.

Method of transmitting control information as part of the composite television signal, does not limit this scope of the method and system of the present invention. As shown in the example in Fig. 8, another possible application is the use of transmission through the telephone network, where the computer 29 host service associated with the telephone station 30 connected to a conventional telephone network, which may include any telephone device 31 connected to the user computer 32. In this case, also, the signal received by the telephone station user 31 can be transferred to computer 32 via a connection cable or, as pokazateli of the invention in the installation user is what specialized software that performs search and decoding control information, as shown in Fig.3, and generate a user interface between the receiver 6, the memory unit 8 and the processor 9 in the computer by the user, supplemented by certain types of application software program that manages the type of trigger actions in response to the message received control information. Depending on the actual application, such action may have different shapes, for example, display images, play videos, run a video game or its parts, and so on, with the method and system in accordance with the invention is in no way limited to any particular type of action that will be initiated depending on the transmitted message control information.

A typical example of such use may, for example, to serve interactive participation of the audience in entertainment television programmes, for example in the well known show "Wheel of Fortune", allowing the viewer with a computer, to take their own part in the game together with direct participants of this television show.

Another important area of application is the transfer of a message control information to specific groups of people. In this application, the method and system of the present invention can be used for direct mail or advertising, for example, if there are users in the selected group purchasing program, the management of one or more actions that should be taken in response to the message control information recorded on a standard computer media type CD-ROM, and sending users belonging to a specific group, the message control information, which could be transmitted, for example, as part of television advertising, or by direct telephone communication.

From the above-described example with reference to Fig. 7 it is clear that passed in signal, but it can also be a signal that contains only the audio information.

In the framework of the present invention can use a method and system for two-way communication between the host service and one or more user computing systems. In this case, the specialized software that performs the functions of the generator control information and the encoder-side node of the service and the device search control information and the decoder-side user should be provided as a node-side service, and on the user side.
