The storage units 11 are made using microprocessor technology. The clock generator 13 is a highly stable and powerful pulse generator and is

synchronizing block for all blocks and nodes of the proposed device.

All the switches and control buttons used in this device are designed to operate without interference (contact bounce, vibration, contact sticking, etc.). The switches and control buttons are located on the remote control 31, which is in the hands of the viewer, controlling the operation of the device 5. The remote control 31 has, for example, two additional buttons: 1st — on / off the suppression system and 2nd — editing ( accelerated viewing without sound in a compressed form of undesirable information).

The operation of the entire device and its components and units occurs on-line, because television information directly from the television receiver, which receives it from the television station, is fed to the storage units. The received television information on the signal channels passes through all the devices of the system shown in Fig. 1, as well as through the nodes and blocks of the device 5, shown in Figs. 2 and 3.

The device for reproducing television information with the suppression of unwanted information is intended to eliminate the information that the viewer of the television channel does not want to view.

In this regard, one should pay attention to the fact that the viewer cannot influence the on-line television channel, so the viewer must register the on-going television program with a time delay. After that, a registered television program can be presented to the viewer for viewing, and the viewer can edit it to eliminate unwanted information from it, for example, to carry out accelerated viewing without sound of this information.

In this case, the operation of the device can be carried out in two modes: recording mode (recording) of television information and reading mode (playback) of television information. Both of these modes are interconnected, because it is during their joint implementation that this device can perform the functions assigned to it, i.e. edit television information registered with a delay for a specified time. For this, it should be borne in mind that the device is able to record television information during a given time interval. When recording this information, it is quantized into time fragments, which together cover the entire specified time interval. Information on each name fragment is recorded in the corresponding storage unit and subsequently from the same storage unit it is read. At the same time, when reading the registered television information, the viewer of the television program can edit the information and eliminate that unwanted information that he will not view. Typically, this television information reproducing apparatus with the suppression of unwanted information should function as part of the television information reproducing system shown in FIG. Moreover, in the absence of the proposed device in the system, it works as follows.

The television signal, falling on the antenna 1, passes through the amplifier 2 and the detector 3, and through the information channel, which includes the key 6, enters the device 7, which already goes to the screen of the information display device 8. When entering the system of the described device 5 (see figure 1) between the high-frequency detector 3 and the device 7 for controlling the reproduction of television information, the key 6 is turned on in the normally closed state, which changes when the device starts functioning

5. To start the operation of the device 5, the voltage of the source is supplied to it (not shown in Fig. 1), and all its components and units are put into standby mode, and it can begin to function.

To enable the operation of the claimed device 5, it is necessary to turn on a normally open switch 4. At the same time, our device starts to operate in the recording mode of television information, namely, the signal from the antenna goes to the input of the analog-to-digital converter 12, but no signal processing occurs. When the signal circuit is closed using a normally open switch 4, the signal from the output of the high-frequency detector begins to flow into device 5, where the process of recording (recording) television information begins. At the same time, the entire system for reproducing television information continues to function, as the key 6 is in the closed state and on the channel between the devices 3 and 7 passes the television information that appears on the screen of the information display device 8. At this moment, a television “picture” is displayed on the screen of the device 8 and the television information is recorded in the device 5. From this moment, we consider the operation of the proposed device 5 in the recording mode of television information. In this case, when the switch 9 and the first control button 10 are pressed simultaneously, the implementation of this mode begins. In this case, a clock generator 13 is activated, synchronizing the operation of all nodes and blocks of the device and a single pulse generator 14, which is supplied to the timer 15 and the first pulse counter 16 (see Fig. 2). From the output of the counter 16 pulses, the signal goes to the decoder 17, the outputs of which appear code combinations, which, on the one hand, are fed to the inputs of the unit 18 for indicating the number of the operating storage unit 11 and to the corresponding control keys 26, which connect the selected unit 11 to the recording mode. It should be noted that each memory

block 11 is designed to register its corresponding (depending on the number, which sequentially increases) going on-line time fragment. This is due to the fact that the working unit 12 provides digitized information to the signal channel. At the same time, this information when sequentially turning on the keys 26 (the recording circuit is closed) in one or the storage unit 11 (see figure 2). In this way, until the storage unit 11 is connected to the operation, it registers the last time fragment from the predetermined time interval of the television information on-line. Upon completion of registration of the last fragment, the output of the corresponding unit 11 is a signal to a single pulse generator 19, which, when activated, turns on a single pulse generator 21 and a timer 22. From this moment, the proposed device starts operating in the information playback mode. It should also be emphasized that when recording the last fragment and the specified time interval of television information from the corresponding block 11 to the key 6, which opens the signal channel between blocks 3 and 7 (see figure 1), and now the information in playback mode is transmitted to the screen of the device 8 for displaying information from the proposed device 5. The viewer begins to actively work with this information, changing fragments of his viewing on the screen of the device 8 using the control button 20.

Consider the operation of the proposed device 5 in the playback mode of television information, in the implementation of which the viewer participates. In this case, the viewer presses the control button 20 and the resulting pulse is fed to the input of the single pulse generator 21. From its output, a single pulse is fed to the reset counter 23 pulses and to the input of the timer 22. The timer 22 is configured so as to supply control pulses to the input of the counter 23 pulses at equal intervals

time, the duration of which corresponds to the duration in the on-line time fragment of a given time interval of television information. Moreover, this duration also corresponds to the time that information was stored by the storage units 11. From the outputs of the pulse counter 23, the information goes to the input of the decoder 24, at the outputs of which a code combination corresponding to the quantitative content of the pulse counter 23 occurs. These code combination signals go to the display unit 25, showing the information about the number of the turned on storage unit 11 and to the corresponding information reproduction control key 27. The included key 27 closes the contacts of the information channel (bus) coming from the corresponding block 11. The selected block 11, under the influence of the clock frequency generator 13, sends the television information stored in it in the form of corresponding signals to the digital-to-analog converter 30 and after it to the input of the device 7 for subsequent conversion of the received information on the screen of the device 8.

Sequential reading of information from all storage blocks 11 ultimately leads to the last block 11, in which information is accumulated for the last fragment from a given time interval of television information. Upon completion of the reading of information from the last storage unit 11 through the delay line 29, a signal is supplied to the input of the additional information reset unit 31. From the output of this circuit, the received signal goes to the input of the pulse counter 23 and resets as a result of its appearance the pulse counter 23 itself, the decoder and the display unit 25.

In the case when the viewer of the television program while watching it on the screen of the device 8 considers it necessary to suppress the appeared television information coming from one of the blocks 11

(his number appears on block 25) and wants to interrupt the viewing, moving on to the next fragment, he presses the control button 20.

At the same time, a new pulse arrives at the pulse counter 23, and its state increases by one. At this time, the timer 22 is activated from the generator 21 and begins a new countdown, which corresponds to the current fragment. After that, the corresponding signal coming from the counter 23 pulses is decrypted and gets to the display unit 25, showing the number of the current storage unit 11 and through the corresponding key 27 of the playback control to read unit 11. In this case, information from this unit 11 passes through the corresponding channel through digital-to-analog Converter 30 and through the device 7 to the device 8 and is displayed in the form of a television picture on the screen of the device 8.

It should be noted that during operation of the device 5, it is necessary to ensure that its playback and recording modes are separated from each other in time by a value of three to four times the length of the time fragment.

Using this utility model increases the efficiency of suppressing unwanted television information through the use of recording and reading television information.
