Description

Technical field

The invention relates to television (TV) technology, in particular, to subscriber devices specifically designed for receiving content or interacting with content, for example, STB (set top box) and their operation; operations for processing content or additional data, for example, demultiplexing additional data from a digital video stream; operations for saving and restoring original content from a local local storage medium, for example, a hard disk; auxiliary operations, for example, prioritizing content components for accumulation and their subsequent storage in a local local storage medium; operations for splitting a multiplexed stream, for example, demultiplexing audio and video streams and extracting additional data from a video stream, re-multiplexing multiplexed streams, extracting and processing SI, splitting a packetized elementary stream and identifying its components; to operations of processing elementary video streams, for example, connecting fragments of a video program recovered from local memory with an incoming video stream, including operations of reformatting video signals for home redistribution, storage or presentation in real time, to reproducing images with the automatic exclusion of inserts of commercial (advertising) fragments in the main signal of the broadcast television program and can be used in the subscriber terminal play back television programs.

State of the art

Currently, technologies and equipment are gaining ground that provide the ability to take into account the individual preferences of a particular user during video monitoring and, accordingly, playback of broadcast television signals. In this regard, the ability to automatically eliminate, at the request of the user, with continuous video monitoring from the main signal regarding the time-extended signals of a fragment of advertising inserts or replacing them in the main television broadcast signal of a specific program with video material that meets the individual interests of the subscriber, significantly increases the competitiveness of the reproducing equipment. The competitiveness of the playback equipment also increases the provision of the possibility of accumulation and formation by the user of the currently relevant individual archive of television and radio products. A variety of information materials from such an archive can be reproduced by the user, for example, in the delay interval (time shift) of video monitoring of the main TV broadcast signal, due to the elimination of the specified length of the signal fragments of the advertising inserts from the main segment of the TV broadcasting signal with the subsequent conversion of this segment to continuous television and radio production.

A drawback of modern technical solutions in terms of eliminating, at the request of the user, during video monitoring from the main signal regarding the time-extended signals of the fragment of advertising inserts or replacing the corresponding fragments in the main signal of television broadcasting with video material that meets the individual interests of the subscriber is the need to introduce and use additional, standardized type, information data (timestamps, metadata, elements in the structure of video material or aud of the material) for specifying the start and completion of the advertising insertion fragment. In cases of a high level of interference or changes in the structure of the overall digital stream, including audio and video information materials, synchronization signals, headers, reference time and other types of data, errors may occur in the specification of the reference time data. When implementing the proposed technical solution, such reference time data can also be used, if necessary. At the same time, in the proposed embodiment, it is possible to use, when implementing the necessary conversion, only decoded digital information television and sound signals of a specific program.

From the report “On volume control of broadcasting programs” Abramov V. A., Ozhdikhin G. M., Popov O. B., Richter S. G. at the Seventh industry scientific conference "Information Society Technologies", Moscow: 2013, it is known that in the intervals of signal transmission of the advertising insert, the volume of sound exposure to the listener significantly increases, which is achieved by non-linear conversion of the corresponding source signal. In this case, most often there is a decrease in the dynamic range of the sound signal while maintaining a given level of the corresponding signal. A nonlinear, similar type, decrease in the dynamic range of the component of the sound signal determines the weight redistribution of its spectral components, a concomitant increase in the average signal power and the average component (envelope) of the sound level, loudness and intelligibility of the speech signal in the transmission intervals of the advertising insert fragment. In the form of an envelope signal of a sound signal, this non-linear processing is manifested by an increase in the level of the average (low-frequency) component of the envelope signal. This makes it possible to specify in the envelope signal the sound accompaniment of the television program of the sections, characterized by an increase in the average component.

However, a significant drawback of this method of detecting inclusions of advertising insert fragments in the signal of television broadcasting programs and the formation of the necessary control signal is the absence of taking into account correlation in the corresponding time intervals between changes in the parameters of the audio signal component and changes in the structure parameters of the video information components. The latter is reflected by an increase in errors in the implementation of this method for detecting signals of fragments of advertising inserts in the signals of television programs.

But our proposed option for detecting and eliminating signals of fragments of advertising inserts in a signal of a television program is different in view of changes in the parameters of all components of the signal of a television program in the interval of the appearance, continuation, and completion of a signal of a fragment of an advertising insert in relation to the previous and subsequent time intervals.

A known method for detecting fragments of images containing components that cause discomfort during the perception of the main signal of a television broadcast program [Pat. 2198472 Russian Federation, IPC H04N 5/00, H04N 5/14, H04N 5/235, “Method for recording and analyzing parameters of television images” / Nemtsova SR, Demircheglyan GG, claimed 16.05.2000], a distinctive feature which is that before measurements, adjustments are made to exclude the influence of ambient light on the monitor, project fragments of images of different brightness, frame-by-frame viewing of projected fragments, measure the integral brightness of the monitor’s glow at a frequency of 50 Hz, analyze the frequency luminance of images, identify frames corresponding to the maximum sensitivity of the eye to the frequency of flickering brightness, assign sequence numbers to the indicated highlighted frames, select fields whose brightness changes are more than 30% of the white level, select fields that satisfy this condition and are spaced 4 apart -8 fields, analyze the selected fields on the computer according to the algorithm for processing the luminance components of the signal in accordance with the defined threshold value and in accordance with the results of the image processing. botki give recommendations on how to eliminate the detected discomfortable fragments of images from the video.

In this technical solution, when monitoring and measuring the integral luminosity of the glow of the projected fragments of television images, frames (fields) in the structure of their sequence are detected that provoke reproducible images in the region of maximum sensitivity to flicker. The result of applying the considered method is providing the manufacturer (user) of this television and radio production with recommendations for the subsequent elimination of uncomfortable image fragments from the video sequence of the television program.

Accordingly, this method does not provide an automated elimination of uncomfortable fragments and, in particular, signals of advertising fragments from the video sequence, which is a drawback of the considered solution.

A device for subscriber reception is known, which protects the viewer from harmful psychophysiological during video monitoring of television broadcasting programs [Pat. 2261533 Russian Federation, IPC H04 N 7/16, H04N 7/173, H04N 7/12. “A device for receiving digital TV broadcasting signals, which protects the viewer from harmful psychophysiological influences from the TV broadcasting program” / Zubarev Yu. B., Krivosheev MI, Lopato SI, Kasatkin AA, Minkin V. M., Plotnikov A.A., claimed 02.02.2004]. The technical proposal under consideration is intended for the automated detection and detection of image ripple in the frequency range 6–13 Hz with a brightness modulation depth of more than 30% of the white level. If they are detected, an automated blocking of the playback of this fragment of images is implemented with its replacement by a static image from the memory or switching of playback to another channel for the period following harmful ripples. Another possible option for operation is the operational adjustment of the TV image, which ensures the removal or reduction of the ripple depth at frequencies of 6-12 Hz to a value safe for the subscriber. In this case, the maximum decrease in the modulation depth occurs at a frequency of 10 Hz. This device contains a central processor, a system bus controller, a first demultiplexer, video and audio decoders. To solve the problem, a scaling unit, a first delay register, a block of pixel block formation, a buffer register, a second delay register, a motion vector calculation unit, a first subtracter, a second demultiplexer, an enlargement unit, a ripple filter unit, an amplitude block are additionally introduced into the known subscriber reception device detectors, multiplexer, backscaler, second subtractor. At the same time, the central processor provides here the control functions of all units of the device. The system bus controller converts the control command signals received from the central processor into signals transmitted to the units of the device, implements procedures for exchanging signals on the system bus between the units of the device and between the central processor and units of the device. The first demultiplexer is designed to isolate from the composition of the multi-program digital TV broadcast signal received from the tuner output a separate TV program signal selected by the subscriber. Video and audio decoders are implemented in the device [Pat. RF 2261533] decompression of TV image signals and sound signals that were subjected to spectrum compression in accordance with the MPEG-2 standard. The introduced scaling unit converts the original image with a dimension of 720x488 pixels into an image with a dimension of 90 × 61, the first delay register ensures that the original image of the given field of the TV frame is time-aligned when the filtered image of the human health component of the pulsation of the brightness signal is removed from the original image of the TV frame field. At the same time, the block of forming blocks of pixels ensures the separation of the image signal of dimension 90 × 61 into 24 blocks of dimension 15 × 15 pixels. A buffer register is necessary for searching for motion vector signals when each of the received 24 blocks of dimension 15x15 of the signal of the current field is compared with each of the 24 blocks of the signal of the previous field. In the block for calculating motion vectors, image blocks are detected for which pulsations of the brightness signal with a frequency of 6-12 Hz are characteristic. The second delay register takes into account the delay of the TV image signal due to the calculation of the motion vector signal. The first subtractor provides the subtraction of the corresponding difference between the pixels in adjacent frames (fields) from the pixel values in each of the 24 blocks of 15 × 15 in the image of the small (90 × 61) dimension of the current field, which allows you to compensate for the changes in the spatial (intra-frame) within the blocks ) structure of image signals associated with the movement of objects. The calculated difference signal is fed to the second demultiplexer, the outputs of which receive divided difference signals for 24 blocks of dimension 15 × 15 from an image signal of dimension 90 × 61. The enlargement unit, by combining the signals of adjacent (four out of twenty four) blocks, generates independent signals corresponding to six regions within the intraframe space. The ripple filter block provides independent selection of brightness ripple signals with a frequency of 6-12 Hz for each of the six image zones. Reducing (zeroing) the level of the received ripple signal with a frequency of 6-12 Hz is implemented in the block of amplitude detectors if the ripple depth is less than 30%. In the multiplexer, a combination of six parallel signal areas of the television image takes place. The reverse scaling unit is designed to restore the original dimension of 720x488 ripple image signal with a frequency of 6-12 Hz. This signal is subtracted (in the second subtractor) from the delayed original image in the case when the depth is a value of 30% or higher. Thus, suppression of the filtered signal of ripple components with a frequency of 6-12 Hz is realized by the considered device in the TV image signal only when their level exceeds a relatively high value, which eliminates the possibility of the accumulation of undesirable effects on the observer with a relatively long video monitoring.

The disadvantage of the above method [Pat. RF 2198472] and devices [US Pat. RF 2261533 is the lack of accounting for the accumulation of harmful effects in cases of a significant extent of pulsation fragments having a level below the threshold value of 30%, and the lack of correction of the current information content of television broadcast programs taking into account the individual preferences of the subscriber.

More effective in this regard are the technical solutions proposed in the invention protected by US patent [US Patent No. 8,064,819. “Seamless switching between radio and local media” // Mikhail Ingrassiya M.T. San Jose, California (USA), Lee, Jeffrey T. Sunnyvale, California (USA); 04/17/2009] and in the continuation of this invention [US Patent No. 8,249,497. “Seamless switching between radio and local media” // Mikhail Ingrassia MT, San Jose, California (USA); Lee, Jeffrey T., Sunnyvale, California (USA); 10/14/2011]. Moreover, the invention [US Patent No. 8,064,819] is taken into account in its continuation [US Patent No. 8,249,497] in its entirety. Technical solutions presented in the specified [US Patent No. 8,064,819 and US Patent No. 8,249,497] method and devices of inextricable (seamless) switching of radio and other electronic media production options, provide the creation of an individual (local) archive of product segments, taking into account the preferences of the individual user, and the implementation of inextricable (seamless) switching of segments of electronic media products at those moments when changes in the current (received) information are not consistent correspond to the established circle of interests of the user. In particular, the proposed method [US Patent No. 8,064,819] provides for the parallel receipt of information segments of electronic media products from many independent points, ensuring its formation and transmission, sequential reproduction of information segments of products from each of the points, identifying current information from points of information arrays (segments) of no interest to the user, parallel identification of segments of the production of electronic means of mass information from other points or from an individual (local archive) that are of interest to the user, and inextricably switching (smooth transition) of playback to the identified segment, which is of greatest interest to the user at the present stage. At the same time, it is envisaged to receive, extract, record and form media products, data, catalogs, metadata, specific characteristics of information (profile of the broadcaster’s preferences) coming from each of the independent points that correspond to independent information points of transfer (delivery) of media products, assessment according to correlation criteria, in relation to the contents of the user's individual archive and taking into account all the specified data and characteristics of the incoming information segments with subsequent automatic non-execution by an explosive connection to the information segment being played for the user, which is of greatest interest to him in streaming broadcasting. An electronic device for operative and inextricable switching of audio broadcasting product segments according to this [US Patent No. 8,064,819] technical solution contains elements of selective radio tuning, memory and a central processor that provides radio tuning control, identifying that the subsequent segment of this broadcasting source is not of interest to the user , identification and automatic, without breaks, reproduction of segments of broadcasting of interest to the user from another and source, from an individual archive or from RAM. At the same time, the central processor of this electronic device, when playing the current segment from one of the sources, reveals that the subsequent (from another source) broadcasting segment is of interest to the user, writes the latter to the random access memory (buffer) with its continuous connection for automatic playback completion of the current segment being played. At the same time, the central processor compares the segments stored in the buffer and excludes from playback those that are less correlated with the user preference profile, and also simultaneously detects among controlled broadcast sources that transmit the next segment of greatest interest to the user , and, ultimately, provides a transition, without gaps, from playback from the buffer to playback from the radio broadcast.

In practically the same way, the functioning of the proposed method for operational and seamless switching of playback of product segments according to this [US Patent No. 8,064,819] technical solution in cases of reproducing products of other media is implemented: in automatic mode, information segments are evaluated by correlation (user preference profile) criteria, identifying and the inclusion of broadcast sources similar in accordance with the specified criterion in the same cluster (group) taking into account the contents of the buffer and the archive, including using metadata and other (machine-readable) media (instructions), as well as the relative identification of the segments of greatest interest to the user, and their connection to playback automatically and without breaks.

In essence, technical solutions for a later patent [US Patent No. 8,249,497] Ing. MT, Lee, Jeffrey T. only expand the scope (claims) of the first technical solution [US Patent No. 8,064,819] to the first and second set of user information elements with their sequential reproduction, taking into account the preference criterion for segments from the first set, revealing that the information flow of the first set of media is not of interest to the user with switching, without gaps, to play oizvedenie information stream from the second plurality of media.

In this case, a relative assessment of the relevance for the user of the arrays of the first and second information flows with smooth switching, according to the evaluation results, to the reproduction of the corresponding subsequent media segments of each of the flows is made.

As a source of mass media of the first stream, terrestrial radio stations, Internet radio stations and special broadcast sources or AM radio, FM radio, Internet radio and a special broadcast signal can be used. The second stream is connected to an electronic playback device [US Patent No. 8,064,819] through sequentially connected matching unit (host device) and a communication channel that is wireless or that uses the Internet. In some cases, the second stream is information signals, data signals, automatically analyzed (machine-readable) instructions (for evaluating information segments according to correlation criteria), metadata that are associated with the first stream and pre-loaded (into memory) of the electronic playback device. One of the signal sources of the first set may include music, sports or advertising segments of the broadcast. When implementing switching, without gaps, in the considered technical solution [US Patent No. 8,249,497] it is proposed to preliminarily add automatically analyzed (machine-readable) instructions to the buffer memory to identify information segments of the first stream according to the user's preference criteria.

Closest to the proposed invention in technical essence is a method and device for generating metadata for identifying information content of a video stream using text data (subtitles, metadata, instructions of the provider, etc.) [US Patent No. 8,136,140. “Method and device for generating metadata used to filter content from a video stream using text data” // Kenneth Robert Hodge, Castle Rock, Colorado (USA); November 20, 2007], intended for separating alternating informational components of a video stream, including specifying, for example, the first informational component from the structure of the video stream that is not reproduced, and the next (second) informational component that is reproduced, parsing the text content of subtitle lines accompanying the video stream and reflecting the content of the first and second information components of the structure of the video stream, the identification, by the content of the subtitle lines, of the current frames of the television signal, respectively of the beginning, the continuation of the transmission of the second information component and the completion of its transmission with the formation of the accompanying signals of temporary identifiers (time stamps), an assessment of the sequence of values of the required offset intervals (for playback without time gaps) of the segments of the second information component of the video stream with respect to the signal of the corresponding first television frame (the beginning of the transmission of the second information component of the video stream), the formation of the initial and of course subtitle rows, the connection IDs of received signals of the current time and video signals corresponding to use text subtitle rows, the digital VCR for subsequent recovery (crosslinking) of the second reproduction signal continuity information component to include the accompanying text subtitle rows.

Moreover, the subtitle line text signals connected to the digital video recorder are characteristic (unique) for the second information component, the connected signals may also include in their structure corresponding to the video stream metadata data signals reflecting the individual preferences of the subscriber with respect to segments of the reproduced (second) information component of the video stream for additional conversion of the second component of the video stream and the text of the accompanying subtitle lines.

The second version of the method proposed by the authors [US Patent No. 8,136,140] provides, along with the determination of the start (and end) moments and the formation (use) of the corresponding timestamp signals for continuous (seamless) reproduction of the signal of the selected information component of the video stream, for example, the first segment and signal accompanying lines of subtitle text, evaluation of data signals, reflecting, in a sequence of frames (in time), the values of the intervals of the displacements of the boundaries of the first (previous d) and the second (subsequent) segment of the reproduced component of the video stream with respect to the moment (in the sequence of frames) of their connection (stitching) and the connection of the received signals, reflecting the value of the indicated offset intervals and lines of subtitle text, to the digital video recorder with the corresponding specification (elimination) the sequences of subtitle text lines used in the playback of the original video stream of the selected informational component of the video stream. Moreover, the subtitle line text signals connected to the digital video recorder are characteristic for a given segment of the reproduced information component, can reflect data signals in their structure reflecting the individual preferences of the subscriber with respect to the reproduced segment of the information component of the video stream with additional text conversion of the accompanying subtitle lines, and are formed with preliminary recording the reproduced information component of the video stream during the first go broadcast.

The third version of the method proposed by the authors for generating metadata for identifying the information content of the video stream using text data differs from the first two in that it is proposed here to pre-record the signal of the reproduced component of the video stream and the data signals of the text data of the corresponding subtitle lines or at least its first section in file during the first broadcast, evaluate, for example, during video monitoring of the recorded section, the position parameters in the follower osti frames (in time) of the moments of the first transition from the segment of the signal of the video stream corresponding to its reproducible component to irreproducible, and the second transition from the segment of the signal of the video stream corresponding to its non-reproducible component to reproducible, to generate accompanying data signals and text signals of the first and second lines subtitles that determine, among other things, the labels of the start and end frames of the monitored segment of the video stream signal corresponding to its reproduced In addition, the signals of the text of the subtitle lines in the order of the subsequent playback of the video signal of the segment in the frame sequence, determine the values of the necessary offsets for stitching, without gaps, the previous and subsequent segments of the reproduced component of the signal of the video stream, and connect the received signals of the text of the subtitle lines, the values of the intervals of the necessary offsets and data to the digital video recorder and their use when playing the selected component.

In this case, subtitle line text signals connected to a digital video recorder are characteristic (unique) for a given (current) segment of a reproduced information component, and a component of a video stream restored to a continuous form is reproduced in the broadcast mode of television programs in various time zones.

The disadvantage of the considered method, for all three versions of the generation of metadata for identifying the information content of the video stream using text data [US Patent No. 8,136,140], is the difficulty of implementing an automated assessment of the time identifiers necessary for seamless recovery of the selected component of the original video stream using only the current text string data subtitles, metadata and various timestamps included in the original video stream and lack of accounting, when implementing the decree This includes automated assessment, correlation in the corresponding time intervals between changes in the text of the subtitle lines, changes in the parameters of the audio signal component, and changes in the structure parameters of the video information components. The latter is reflected by an increase in errors in the implementation of this method of detecting signals of fragments of advertising (and other) type of inserts in the signals of television programs and, therefore, the formation of the necessary signals for temporary identification of the components of the original video stream.

A system (device) that implements a method for generating metadata for identifying information content of a video stream using text data [US Patent No. 8,136,140], which contains a digital video recorder unit, to the input (inputs) of which through the transmission network is connected the output (s) of video stream signals, metadata and lines associated with the video stream, subtitle text from the signal conditioning block of broadcast television programs, the output of the digital video recorder block, which is connected to the reproducing subscriber device, while the structure of the digital tape recorder unit includes a receiver unit, inputs (input), which is connected to the input (inputs) of a digital tape recorder unit, a unit for operational recording of signals, an analysis (generation) unit for identification signals, the inputs of which are connected to the outputs of the receiver, a memory unit (address storage), the inputs of which are connected via the online recording unit to the outputs of the receiver and to the outputs of the other blocks of the structure of the digital tape recorder listed above, the output of the signal analysis (generation) block ID identification, the playback signal generating unit of the selected component of the video stream, the inputs of which are connected to the outputs of the receiver units, the operational recording unit of the signals, the memory unit (address storage), the outputs of the generating unit of the playback signal of the selected video component, which are connected to the first output of the digital tape recorder, the second output of which connected to another output of the analysis (generation) block of identification signals.

The receiver unit used in the structure of the digital video recorder unit of this system [US Patent No. 8,136,140] can carry out wired or wireless reception of video stream signals, instruction, data, metadata and lines, the accompanying video stream, subtitle text from the broadcast television program signal generating unit. The recording unit records the signals of the original video stream, data, metadata, text lines of subtitles, additional instructions, etc. in the memory unit (digital media of any type). In the block of analysis (generation) of identification signals, a comparative assessment of the instruction signals, data, metadata and lines, the accompanying video stream, subtitle text is implemented. As a result, at the outputs of this block, a time identification signal (labels and values of the offset intervals) of the plot sequence of the user selected digital stream component is generated. The identification signal is fed to the playback signal generating unit of the selected component of the video stream, which ensures the necessary, without interruption, reading sequence of the selected component sections in the memory unit and elimination of the component signal inserts of commercial (advertising) fragments that are present in the signal of the original video stream.

The disadvantage of the system (device) that implements the considered method of generating metadata for identifying the information content of the video stream using text data [US Patent No. 8,136,140] is the dependence of the efficiency of eliminating the component inserts of the signal fragments of a commercial (advertising) nature present in the signal of the original video stream, on the quality of the formation and transmitting data signals, metadata, subtitle text lines, additional instructions, etc. to the device inputs. Allowed deterioration transmission quality and the identification of these signals, as well as disorders of ambiguity and the subtitle text strings structure recognized to decrease the precision in estimating timing current signal insertion fragment into the main video stream and to the corresponding operation mode of a device in general. A possible transition to manual control in this case drastically slows down the execution of necessary operations, is highly labor-intensive, and at the same time does not guarantee that errors do not occur in estimating the necessary time parameters of user-insigned insert signals in the main video stream.

In this device (Fig. 1) for reproducing broadcast television image signals, the component signals of the provider's instructions, closed captioning, metadata and video stream are received in the receiver 5 at the input (s) 1, 2, 3, 4. The structure of these signals may also contain standardized signals data and typical inclusions (labels) that are directly intended to be specified in a sequence of frames of moments of time, reflecting, for example, the beginning and end of the signal of the advertising insert. Decoded independent signals from the output of the receiver are connected in parallel to the inputs of block 6 for separating the signal of the television program into components for sound, brightness and color difference signals and are connected to the inputs of block 7 for controlling the local time sensor 8, block 14 for extracting signal signals for instructions, block 15 for extracting subtitle line signals , block 16 allocation of metadata signals (labels) and block 17 operational and address recording. The outputs of the specified block 17 operational and address records are connected to the inputs of the block 22 address storage.

If there are corresponding signals or some of them at the input of the receiver 5 of the device for reproducing the image signals of broadcast television in blocks 14, 15, 16, data signals are selected that allow you to specify the information structure and the sequence of time of video and audio of individual information messages in the signal of a separate broadcast program television. In control unit 7, the video materials of broadcast television programs of interest to the user that are input to the receiver 5 within the specific subsequent local time intervals are specified. In accordance with the user-defined distribution (schedule) of the indicated time intervals, the output signals of local time are generated in the sensor 8. The transmitted data signals obtained by extraction (decoding in blocks 14, 15, 16) are fed to the inputs of the block 21 for identifying the temporary parameters of the insert signal, where a comparative assessment of the received instruction signals, data, metadata, and lines accompanying the video stream of the subtitle text is realized and the corresponding the results of such an assessment, identification signals reflecting the values of the necessary time parameters for the sequence of information messages included in this television program. In particular, at the outputs of the insertion time parameter identification block 21, in the case of the presence of data signals intended for this purpose in the video stream, a time identification signal (positions of regular marks and values of the offset intervals) of the plot sequence of the user-selected component of the digital stream, allowing to exclude in the converted a variant of television and audio production of a specific television program, undesirable (for a specific user) fragments (inserts) corresponding to and Khodnev its embodiment.

In block 6, the signal is divided by a user-defined television program into constituent sound, brightness, and color-difference signals, and a common video stream is decoded to produce independent digital streams that reflect the above informational components of a specific television program signal. The independent digital component streams obtained in block 6 are supplied to the multiple delay unit 9 of the audio signal, brightness, and color difference signals, the structure of which includes the independent multiple delay unit 10 of the audio signal component, the multiple delay unit 11 of the brightness signal component, the multiple delay unit 12 component of the first color difference signal, block 13 multiple delay component of the second color difference signal. At the outputs of these blocks 10, 11, 12, 13 in parallel there are sets of multiple times delayed by time intervals that are multiples of the duration of the frame of the television signal, the components of the sound signals, brightness and color difference signals. At the same time, the signals of the components not delayed and delayed at different intervals are combined in time by frames, rows, and individual pixels within the rows. This provides the possibility of their subsequent relative mutual processing in the device for reproducing signals of images of broadcast television.

From the output of block 8 of the local time signal sensor, synchronization signals of the program, clock frequency and local time signals (SMW) are fed to the first input of the block 19 for adjusting the duration of the reference intervals. At the same time, the local time signals generated in block 8 are also fed to the control input of the receiver 5, ensuring its inclusion in the operating mode at user-specified local time intervals and the selection of a given broadcast television program. Using local time signals from block 8, arriving at the corresponding control inputs, they realize, within the user-defined time intervals, the operational and address recording unit and address storage unit 22 and other necessary device units being included in the operating mode of operation. At the same time, the structure of the address storage unit 22 includes an operational address storage unit and an archive address storage unit. At intervals, according to the local time of reproduction of the transmission selected by the user from a specific television program, the corresponding portion of the television broadcast signal is recorded in the indicated operational address storage unit, which is part of the structure of the address storage unit 22. In this case, the identification of the address is determined by the program and the local time of operational archiving.

The adjustment of the duration of the reference intervals, implemented using block 19, is based on the choice, including with the participation of the user, for each specific (from the user specified) broadcast television programs in the range, for example, the possible minimum, average and maximum values of time intervals that reflect temporal parameters of the eliminated fragments (inserts) and their changes over the course of local time. From the outputs of block 19, signals specifying the specified time parameters are supplied to block 27 of generating signals of reference intervals. Taking into account the indicated selected typical values of the intervals corresponding to the eliminated inserts, and the specifics of their dependence on local time within the video materials of this broadcast television program, the block 27 generates signals of the values of the reference intervals (SDI) received at the outputs 32 of this block.

Independent delayed and uncontrolled components of sound, brightness, and color-difference signals are fed to a block 20 of the selection of signals of time parameters, the structure of which includes the first block 23 of the selection of signals of temporary parameters, the second block 24 of the selection of signals of temporary parameters, the third block 25 of the selection of signals of temporary parameters, the fourth block 26 of the selection of signals of time parameters. At the same time, in the first block 23 of the selection of signals of time parameters, the independent inputs 34, 36, 38, 40 receive delayed by the time (nТк) multiple of the frame duration (Тк), and the independent inputs 35, 37, 39, 41 arrive (according to FIG. .2) components of the luminance signal, sound, the first and second color-difference signals of a television program delayed for, for example, the duration ((n + 1) Tk). In the first block 23 of the selection of signals of time parameters, pairwise distribution (pairs: 34, 35; 36, 37; 38, 39; 40, 41) of inputs delayed for a while (pTk) and delayed for a time ((n + 1) Tk of components, respectively the same-named brightness, sound, first and second color-difference signals of a television program. As shown in figure 2, these distributed pairs of signals of the delayed components are connected to the first and second inputs of each of the four blocks - the first block 42, second block 43, third block 44, fourth bl to 45 - the formation of averaged and subsequent frame-rate samples of the envelope of changes in the level of the components of the brightness signal, sound, first and second color-difference signals of the television program, connected to the inputs of the first block 23 of the selection of signals of time parameters, in particular, the inputs 34, 35 delayed time (nTk) and delayed by time ((n + 1) Tk of the luminance signal component are connected to the inputs of the first block 42 for generating averaged and subsequent envelope samples with a frame rate the level of these input delayed signals of the luminance component, which are unipolar. The indicated luminance signals at the inputs 34, 35 are usually characterized by the presence of an average component or its restoration is carried out through the use of a damping level fixing circuit. Correspondingly, the envelope samples of the change in the data level (delayed by time (nTk) and by time ((n + 1) Tk) of signals following with a frame rate can be obtained in this block by averaging delayed by time (nTk) and delayed by time ((n + 1) Tk of the luminance signal component in the interval of each frame. The pairs of delayed by time (nTk) and delayed by the time ((n + 1) Tk components of sound signals (inputs 36, 37 of block 43 in figure 2) , the first color difference signal (inputs 38, 39 of block 44 in FIG. 2), the second color difference signal of the TV program (inputs 40, 41 of block 45 in figure 2) do not contain average components.Therefore, initially in blocks 43, 44, 45 receive signals from the modules (detection) of input delayed by time (nTk) and delayed by time ((n + 1 ) Tk of the components of the soundtrack, the first and second color-difference signals of the television program.Then the envelope samples of the level change of the indicated signals, following with the frame rate, are formed in these blocks by averaging the signals of the modules delayed by time (nТк) and delayed by time ((n +1) Tk comp -governing sound signal, the first and second color difference signals of a television program in each frame interval. Therefore, the first and second outputs of each of the four blocks 42, 43, 44, 45 (Fig. 2) receive the averaged and the next with the frame rate samples of the envelopes of the changes in the level of the components, respectively, of the brightness signal, sound, first and second color-difference signals of the television program. The indicated pairs of outputs of these (42, 43, 44, 45) blocks are connected, according to the scheme of FIG. 2, to the inputs of the first 46, second 47, third 48 and fourth 49 subtraction blocks. At the outputs of the blocks (46, 47, 48 and 49), subtractions receive the difference signals delayed by time (nTk) and delayed by time, for example, ((n + 1) Tk of samples of the envelope of changes in the level of the components, respectively, of the brightness signal, sound, first and of the second color-difference signals of the television program. Changes in the level of difference signals at the outputs of the first 46, second 47, third 48, and fourth 49 subtraction blocks exceed changes in the level of noise components only in the regions where the envelope samples follow, differing in the presence of relative relatively high-gradient changes in the level of the components of the luminance signal, sound signal, or the first and second color-difference signals of the television program. as a result of subtractions, in blocks 46, 47, 48, 49, differential processing of the envelope samples of the level changes x, respectively, the brightness signal, sound, the first and second color-difference signals of the television program. The received signals of the difference of the samples from the outputs of the subtraction blocks are supplied to the first 50, second 51, third 52 and fourth 53 blocks of inverters of polarity of the independent input difference signals. Therefore, the output of each of the blocks of subtraction 46, 47, 48, 49 contains signals of a difference of a given polarity, and at the inverter outputs 50, 51, 52, 53 the same signals of opposite polarity. The difference signals of the given and opposite polarity from the outputs of the subtraction units and inverters are connected to the inputs of the first 54, second 55, third 57, fourth 56, fifth 58, sixth 59, seventh 60 and eighth 61 blocks of the threshold estimate. Essentially, in these blocks a threshold nonlinear detection is made in the structure of the input signals of the difference of the sections within which the initially set threshold is exceeded by the signal level of the difference of the selected (for example, positive) polarity, and then it is exceeded - of the opposite (negative) polarity. In time, such sections are associated with intervals of a sharp increase and then a drop in the level of the components of the brightness signal, sound, the first and second color-difference signals of the television program. Due to the nonlinear threshold processing, control signals are generated in blocks 54, 55, 57, 56, 58, 59, 60, and 61 of the threshold estimate, specifying the indicated moments of occurrence and completion of the mentioned level jumps in the sequence of frames of the components of the brightness signal, sound, the first and second color difference signals of a television program. From the outputs of the blocks (54, 55, 56, 57, 58, 59, 60, 61) of the threshold assessment, the received signals identifying the sections (intervals in the sequence of frames) of the increased level of the components of the brightness signal, sound, the first and second color-difference signals of the television program are received on the first 62, second 63, third 64 and fourth 65 blocks for evaluating the parameters of the duration of the intervals that specify in the sequence of frames the moments of occurrence (beginning), continuation (duration) and completion (end) of increases in the level of The audio and video signal of a television broadcast program. The outputs of the generated control signals from the blocks (62, 63, 64, 65) for estimating the interval duration parameters are connected to the first 66, second 67, third 68, and fourth 69 blocks of relative calculation of the interval duration into a signal of a specific broadcast television program. Other inputs of the indicated (66, 67, 68, 69) blocks are connected to the outputs 32 of the block 27 of the formation of signals of the reference intervals. In block 27, the value of the beginning of the given program in local time is specified and specified, based on the current parameters of the advertising inserts in the signal of each individual, regional or federal program, the average values of the time parameters of the implementation of the advertising insert: the minimum and maximum values of the duration of the signal of the advertising insert, duration repeating (after the end of the display of the advertising insert) the previous plot of the main program of broadcast television. The indicated local time parameters and statistically averaged, current minimum, average and maximum values (range of values) of the duration of the advertising insert signal are compared in blocks (66, 67, 68, 69) of the relative calculation of the duration of the intervals of the fragments of the advertising insert with the calculated durations of the generated control signals received in blocks (62, 63, 64, 65), reflecting the moments and intervals of relative increases in the level of the components of the audio and video signal of a given broadcast television program by relevant to local time. The result of the comparison is the exclusion from control signals generated using the individual components (audio and video) of the signal of a given broadcast television program, those that are not included in the range of acceptable values for the duration parameter and, therefore, a decrease in the number of options for each of these components intervals corresponding to the probable localization of the signals of advertising inserts. In the first block 70 of the formation of the output signal of the values of the time parameters, a comparison of the values of the signals of the time parameters received from the blocks (66, 67, 68, 69) of the relative calculation of the duration of the intervals of the fragments of the advertising insert is implemented and finally the control signals reflecting the coordinates of the signals of the advertising inserts in the frame sequence the signal of a controlled broadcast television program with respect to the moment of the start of the local time transmission of interest to the user. At the output 71 of the first block 70 of the formation of the output signal of the values of the time parameters, control signals are obtained that reflect the position of the signals of the advertising inserts in the given signal fragments of each of the individual broadcast television programs of interest to the user.

In the second block 24 of the selection of signals of time parameters to the independent inputs 72, 74, 76, 78 are delayed by the time (mTk), a multiple of the frame duration (Tk), and to the independent inputs 73, 75, 77, 79 are received (according to FIG. 3 ) delayed, for example, by a time that is a multiple of the frame duration, (mТк + Тс) components of the brightness signal, sound, first and second color-difference signals of the television program. Moreover, the duration of the delay (Tc) is a multiple of the frame duration and does not exceed the maximum signal duration of a single plot within the general fragment of the advertising insert. Here, as in the first block 24 of the selection of signals of time parameters, pairwise distribution (pairs: 72, 73; 74.75; 76, 77; 78, 79) of inputs delayed for a while (mТк) and delayed for a time (mТк + Тс ) of correspondingly corresponding brightness signals, sound, first and second color-difference signals of a television program. As shown in figure 3, these distributed pairs of signals of the delayed components are connected to the first and second inputs of each of the blocks - the first block 80, the second block 81, the third block 82, the fourth block 83 - subtracting the components respectively of the brightness signal, sound, first and the second color-difference signals of the television program connected to the inputs of the second block 24 of the selection of signals of time parameters. At the output of the subtraction blocks 80, 81, 82, 83, the difference signals of the delayed components (mТк) and delayed (mТк + Тс) of the components of the brightness signals, sound, the first and second color-difference signals of the television program are received. Since the adjacent plot signals of the commercial insert have a low level of correlation, there is an increase in the intensity of these difference signals within the interval of the commercial insert signal. The received difference signals are connected to the inputs of each of the four blocks - the first block 84, the second block 85, the third block 86, the fourth block 87 - the formation of averaged and next with the frame frequency samples of the envelope of the level changes of the input signals coming from the outputs of blocks 80, 81, 82 , 83 subtracting time-delayed (mTk) and time-delayed (mTk + Tc) components of the luminance signal, sound, first and second color-difference signals of the television program, respectively. According to the principle of operation, blocks 84, 85, 86, 87 are similar to blocks 43, 44, 45 of the first block 23 of the selection of signals of time parameters. Here, the signals of the modules (detection) of the input signals of the difference of the time delayed (mTk) and time delayed (mTk + Tc) components of the brightness signal, sound accompaniment, the first and second color-difference signals of the television program are received. Then, the signals of the envelope samples of the level changes of the received modules of the difference signals, following with the frame rate, are formed in these blocks by averaging each of the four modules of the difference signals in the interval of each frame. Therefore, the outputs of each of the four blocks 84, 85, 86, 87 (Fig. 3) receive averaged and next with a frame rate signals samples of envelopes of changes in the level of the modules of the difference signal signals delayed by time (mTk) and delayed by time (mTk + Tc) components, respectively, of the brightness signal, sound, the first and second color-difference signals of the television program. These readout signals arrive at the first inputs of blocks — the fifth 92, sixth 93, seventh 94, eighth 95 — subtract directly, and the second inputs are fed through blocks — the first 88, second 89, third 90, and fourth 91 — delays in the signals of the averaged envelope samples changes in the level of the module of the difference signal signals delayed for a time (mТк) and for a time (mТк + Тс) of the components of the brightness signal, sound, the first and second color-difference signals of the television program. At the outputs of the subtraction blocks (92, 93, 94, 95), the signals of the difference between the delayed and delayed by time are received, for example, the frame of the signals of the averaged samples of the indicated envelopes, which reflect the changes in the level of the module of the signals of the difference of the delayed by time (mТк) and by the time (mТк + Тс ) components of the brightness signal, sound, the first and second color-difference signals of a television program. Changes in the level of difference signals at the outputs of the first 92, second 93, third 94, and fourth 95 blocks of subtraction exceed changes in the level of noise components only in the sections of averaged envelope samples that differ in the presence of relatively high-gradient changes in the level of the module of difference signals delayed by time (mТк) and by time (mТк + Тс) components of the brightness signal, sound accompaniment, the first and second color-difference signals of a television program. In areas with no sharp changes in the level of subtracted envelope signals, the samples of the difference signals are localized in the range of levels close to zero, negative or positive. In practice, as a result of subtractions, in blocks 92, 93, 94, 95, differential processing of the signals of the averaged samples of the envelope of changes in the level of the module of the difference signal signals is delayed for the time (mТк) and for the time (mТк + Тс) of the components of the brightness signal, sound, first and second color difference signals of the television program. In its output (after the subtraction blocks 92, 93, 94, 95), the second block 24 of the selection of signals of time parameters is completely equivalent to the first block 23 of selection of signals of time parameters considered above. For example, at the output of each of the subtraction blocks 92, 93, 94, 95, there are signals of a difference of a given polarity, and at the outputs of inverters 96, 97, 98, 99 - the same signals of opposite polarity. The difference signals of a given and opposite polarity from the outputs of the subtracting units and inverters are connected to the inputs of the threshold assessment blocks 100, 101, 102, 103, 104, 105, 106, 107, which realize a nonlinear detection in the structure of the input signals of the difference of the sections within which the initially set threshold it is exceeded by the signal level of the difference of the selected (for example, positive) polarity, and then it is exceeded - of the opposite (negative) polarity. From the outputs of the blocks (100, 101, 102, 103, 104, 105, 106, 107) of the threshold estimate, the received control signals identifying sections (intervals in the sequence of frames) of the increased level of the signal difference module delayed by time (mТк) and by time (mТк) + Tc) of the components of the luminance signal, sound accompaniment, the first and second color-difference signals of a television program are supplied to blocks 108, 109, 110, 111 for evaluating the parameters of the duration of the intervals in which the moments of occurrence (beginning), continuation (d itelnost) and completion (end) increases in the level of said input signals with respect to the top (local time) of a given transmission user within the main program. The outputs of the generated control signals from the outputs of the blocks (108, 109, 110, 111) for evaluating the interval duration parameters are connected to the blocks 112, 113, 114, 115 of the relative calculation of the interval duration corresponding to increases in the level of the signal difference module delayed by time (mТк) and by time (mТк + Тс) components of the brightness signal, sound accompaniment, the first and second color-difference signals of a television program. Other inputs of the indicated (112, 113, 114, 115) blocks are connected to the outputs 32 of the block 27 of the formation of signals of the reference intervals. The statistically averaged and current minimum, average and maximum values (range of values) of the signals of the duration of the advertising insert are compared in blocks (112, 113, 114, 115) of the relative calculation of the duration of the intervals of the fragments of the advertising insert with the calculated durations of the generated control signals received in blocks (108, 109, 110, 111), reflecting the intervals of relative increases in the level of the module of the difference signal delayed for the time (mТк) and for the time (mТк + Тс) of the components of the brightness signal, sound, p the first and second color difference signals of the television program. The result of the comparisons is the limitation of the analyzed intervals, reflecting the indicated increase in the level of the module of the difference signal delayed for the time (mТк) and for the time (mТк + Тс) of the components of the brightness signal, sound, the first and second color-difference signals of the television program. In the second block 116 of the formation of the output signal of the values of the time parameters, a comparison of the values of the signals of the time parameters received from the blocks (112, 113, 114, 115) of the relative calculation of the duration of the intervals of the fragments of the advertising insert is implemented and finally the control signals reflecting the coordinates of the signals of the advertising inserts in the frame sequence a signal of a controlled broadcast television program with respect to the start of a user-defined local time transmission. At the output 117 of the second block 116 of the formation of the output signal of the values of the time parameters, control signals are obtained that reflect the position of the signals of the advertising inserts in the given signal fragments of each of the individual broadcast television programs of interest to the user.

In the third block 25 of the selection of signals of time parameters, the independent inputs 118, 119, 120, 121 receive sets of brightness, sound, and the first and second color-difference signals of a television program that are repeatedly delayed by a given number of different intervals (rTk + Tov). Each of the delay intervals is a multiple, when changing a given sequence of values of a variable integer p, the duration of a single frame (Tk). In this case, the initial (at p = 0) value of the initial delay Tov does not exceed the minimum length of the signal of the advertising insert, characteristic for this television program. At the same time, the independent inputs 126, 127, 128, 129 receive (as shown in FIG. 4) the uncontrolled components of the brightness, sound, first and second color-difference signals of the television program. The sets of components of the luminance signal, sound accompaniment, first and second color-difference signals of a television program that are repeatedly delayed by discrete intervals (rTk + Tov) are connected to the signal inputs of the first 122, second 123, third 124 and fourth 125 blocks of delayed signal switching, respectively. The signals received at the control inputs of the switching blocks determine the order of connecting each of the input signals, which differ in delay time, to the outputs of the switches of the corresponding brightness signals, sound, the first and second color-difference signals of the television program. Consistently, for example, and in the order of a floppy increase in the delay intervals, repeatedly delayed luminance, sound, first and second color-difference signals of a television program can be connected to the outputs of switching blocks 122, 123, 124, 125. The outputs of these blocks 122, 123, 124, 125 switching connected to the first inputs of the first 130, second 131, third 132 and fourth 133 blocks of subtraction, respectively. The second inputs of these subtraction units are connected to the independent inputs 126, 127, 128, 129 of the undelivered components of the brightness, sound, first and second color-difference signals of the television program. When subtractions are implemented, the signals of the difference between the uncontrolled and through the corresponding switching blocks of the connected detainees are received for different time intervals (p = var> 0), the same brightness signals, sound, the first and second color-difference signals of the television program. The outputs of the indicated blocks 130, 131, 132, and 133 of the subtraction blocks are connected to the inputs of the first 134, second 135, third 136, and fourth 137 blocks of the threshold estimation of changes in the signal level of the difference between the unstoppable and delayed components of the luminance signal, sound accompaniment , the first and second color difference signals of the television program. During a discrete increase in the relative duration of the delay, a drop in the level of the difference signal usually occurs. The latter is due to the fact that before and after the signal of the commercial insertion, the signal sections of the main television program most often have a high degree of information correlation or are simply repeated. Accordingly, for example, a discrete, after a given interval, increase in the delay interval value connected through the blocks 122, 123, 124, 125 to the first inputs of the blocks 130, 131, 132 and 133 of the subtraction of the brightness signals, sound, the first and second color-difference signals of the television program provides , upon reaching certain values of the delay interval, the appearance at the outputs of the subtraction blocks in the sequence of frames of the sections in the difference signals, characterized by a sharp decrease in the level of the latter down to the level w mov. The relatively accurate selection of the delay interval allows us not only to specify in blocks 134, 135, 136, 137 the threshold assessment of the difference in signal level differences, the temporal parameters of the signals of the advertising inserts (turn-on time, duration, turn-off time), but also to reveal the duration, again, after the end of the advertising fragment insertion of the reproduced section (plot) of the signal of the main television program. The coordinates of the plots within which the changes in the level of the difference signals are reduced in the sequence of frames to a predetermined minimum limit and are specified in blocks 134, 135, 136, 137 of the threshold estimate of the changes in the level of signals of the difference of the proposed device. Moreover, a discrete increase (selection) of the delay interval (rTk + Tov) of the components of the brightness signal, sound, first and second color-difference signals of a television program, when changing a given sequence of values of a variable integer p, is carried out in blocks 122, 123, 124, 125 switching up until a difference is detected in the difference signals (at the outputs of the subtraction blocks 130, 131, 132 and 133) with respect to the extended section of the specified minimum level. The corresponding control signal is generated in blocks 134, 135, 136, 137 of a threshold estimate of the difference signal level changes, is fed to the control inputs of delayed signal switching blocks 122, 123, 124 and 125 and determines the specificity of discrete changes in the delay values. In blocks 134, 135, 136, 137 of the threshold assessment of level changes, the difference signals undergo integral (averaging) and nonlinear (detection and threshold level restriction) transformations. In its subsequent structure, the third block 25 of the selection of signals of time parameters is not significantly different from the first (23) and second (24) blocks of a similar purpose. From the outputs of blocks 134, 135, 136, 137 of the threshold assessment of level changes, difference signals are converted difference signals that allow to identify sections (intervals in the sequence of frames) of a given minimum level of the signal difference signal module undetected for a time and delayed for a fixed time (p ₀ Tk + Tov) components of the luminance signal, sound accompaniment, the first and second color-difference signals of a television program are sent to blocks 138, 139, 140, 141 for estimating the parameters of the duration of the intervals in which I specify Xia moments in a sequence of frames of occurrence (start), the continuation (duration) and the completion (end) drops to the level of the input signal relative to the beginning (local time) of a given transmission user within the main program. The outputs of the generated control signals from the outputs of the blocks (138, 139, 140, 141) for evaluating the interval duration parameters are connected to the blocks 142, 143, 144, 145 of the relative calculation of the interval duration corresponding to the minimum level of the signal difference signal of undelayed and delayed by time (p ₀ Tk + Tov) components of the brightness signal, sound, first and second color-difference signals of a television program. Other inputs of the indicated (142, 143, 144, 145) blocks are connected to the outputs 32 of the block 27 of the formation of signals of the reference intervals and the local time signal that identifies the beginning of a user-defined transmission. The statistically averaged, current minimum, average and maximum values (range of values) of the signals of the duration of the advertising insert are compared in blocks (142, 143, 144, 145) of the relative calculation of the duration of the intervals of the fragments of the advertising insert with the calculated durations of the generated control signals received in blocks (138 , 139, 140, 141), reflecting the intervals of relative drops in the level of the module of the difference signal of undetected and temporarily delayed (p ₀ Tk + Tov) components of the brightness signal, sound , the first and second color difference signals of the television program. The result of comparisons is the limitation of the analyzed intervals, reflecting the indicated decrease in the level of the signal module of the difference between the undetected and delayed components of the brightness signal, sound, the first and second color-difference signals of the television program. In the third block 146 of the formation of the output signal of the values of the time parameters, a comparison of the values of the signals of the time parameters received from the blocks (142, 143, 144, 145) of the relative calculation of the duration of the intervals of the fragments of the advertising insert is implemented and the control signals reflecting the coordinates of the signals of the advertising inserts in the frame sequence are finalized signal of a controlled broadcast television program with respect to the start of a user-defined local time transmission. Output 14 7 of the third block 146 for generating the output signal of the values of the time parameters, control signals are obtained that reflect the position of the signals of the advertising inserts in the specified transmissions of interest to the user corresponding to the signals of individual broadcast television programs and the reproduced sections of the signal of the main program after the completion of the signal of the fragment of the advertising insert.

In the input part, the fourth block 26 of the selection of signals of time parameters is equivalent to the third block considered above. Here, the independent inputs 148, 149, 150, 151 also receive sets of luminance, sound, first and second signals delayed by a given number of different intervals (rTk + Tov) color difference signals of a television program. Each of the delay intervals is a multiple, when changing a given sequence of values of a variable integer p, the duration of a single frame (Tk). At the same time, the initial (at p = 0) value of the Tov delay does not exceed the minimum length of the signal of the advertising insert, typical for this television program. At the same time, the independent inputs 156, 157, 158, 159 receive (according to FIG. 5) the uncontrolled components of the brightness signals, sound, first and second color-difference signals of the television program. The sets of components of the luminance signal, sound accompaniment, first and second color-difference signals of a television program, repeatedly delayed by discrete intervals (rTk + Tov), are connected to the signal inputs of the first 152, second 153, third 154, and fourth 155 blocks of delayed signal switching, respectively. The signals arriving at the control inputs of the switching blocks are determined in a similar way, as in the third block 25 of the selection of signals of time parameters, the order of connection of each of the input signals that differ in delay time to the outputs of the switches of the corresponding brightness signals, sound, the first and second color-difference signals television program. The output of the first 152 switching unit is connected to the first input of the DC compensation unit 160. Accordingly, the luminance signal of the television program is delayed at various intervals (rTk + Tov) at the first input of block 160 in the given sequence when the values of the variable integer p change. At the second input of block 160, an uncontrolled luminance signal of a television program is connected. At a block 160, a constant component in the delayed and uncontrolled luminance signals of the television program is compensated. The received luminance signals, delayed and uncontrolled, with a lost constant component, respectively, are received at the first and second output of the constant component compensation unit 160, which are connected respectively to the first and second inputs of the first multiplication unit 161. The outputs of the second 153, third 154, and fourth 155 switching blocks of the delayed sound signal, the first and second delayed color difference signals of the television program are connected respectively to the first inputs of the second 162, third 163, and fourth 164 multiplication blocks, to the second inputs of which unreserved components of the same signal are connected this television program.

When implementing multiplications, they obtain signals of the result of multiplications, reflecting the products of uncontrolled and connected ones, in a given sequence through the corresponding switching units, delayed by different time intervals (p = var> 0) of the same brightness signals, sound, first and second color-difference signals of a television program. In the areas of almost complete coincidence of the signals subjected to multiplication, the result of the multiplication is determined within the indicated areas by the input signal to the second degree. This entails a significant change in the constant component in the signals of the result of multiplications in areas with an equivalent form of multiplied signals. The signals of the multiplication result obtained in the first 161, second 162, third 163 and fourth 164 blocks are connected respectively (Fig. 5) to the inputs of the first 165, second 166, third 167 and fourth 168 integration blocks. During a sequential discrete increase in the relative duration of the delay, a conversion usually takes place, within a frame-limited signal of the result of multiplication into a unipolar form. The latter is due to the fact that before and after the signal of the commercial insertion, the signal sections of the main television program most often have a high degree of information correlation or are simply repeated. Accordingly, for example, a discrete, at a given interval, increase (regulation) of the delay interval value connected through the blocks 152, 153, 154, 155 of switching to the first inputs of the blocks 161, 162, 163 and 164 of the multiplication of brightness signals, sound, the first and second color-difference signals The television program ultimately provides, upon reaching certain values of the delay interval, the appearance at the outputs of the multiplication units in the sequence of frames with respect to time-stretched sections in the output signals ata multiplication, characterized by the presence of the constant component. Subsequent integration of the multiplication result signals to a limited extent is reflected in this case by an increase in the level of integrated signals in areas with a constant component, which makes it possible to specify the time coordinates of such sections and the duration of a fragment of the advertising insert, taking into account the established (discrete sequential change) resultant shift interval in the sequence of delayed frames signals in relation to uncontrolled. The outputs of the indicated integration blocks 165, 166, 167 and 168 are connected to the inputs of the first 169, second 170, third 171 and fourth 172 blocks of the threshold assessment of changes in the level of integrated signals of the result of multiplying undetected and delayed components of the brightness signal by the specified number of intervals (rTk + Tov), sound accompaniment, the first and second color-difference signals of a television program. The relatively accurate selection of the delay interval allows us not only to specify in time blocks 169, 170, 171 and 172 of the threshold assessment of changes in the level of integrated signals the temporal parameters of the signals of the advertising inserts (turn-on time, duration, turn-off time), but also to reveal the duration, again, after the end of the advertising fragment insertion of the reproduced section (plot) of the signal of the main television program. The coordinates of the areas within which changes in the level of the integrated signals increase in the sequence of frames to the maximum value are specified, thus, in blocks 169, 170, 171, 172 of the threshold assessment of changes in the level of integrated signals of the proposed device. Moreover, a discrete increase (selection) of the delay interval (rTk + Tov) of the components of the brightness signal, sound, first and second color-difference signals of a television program, when changing a given sequence of values of a variable integer p, is carried out in blocks 152, 153, 154, 155 switching up until it is detected in the integrated signals (at the outputs of the integration blocks 165, 166, 167 and 168) the presence of a relatively extended section of the highest possible level. The corresponding control signal is generated in blocks 169, 170, 171, 172 of the threshold assessment of changes in the level of integrated signals, fed to the control inputs of the first delayed switching blocks 152, 153, 154, 155 and determines the specificity of discrete changes in the delay values. In blocks 169, 170, 171, 172 of a threshold assessment of level changes, the integrated signals are subjected to linear and nonlinear transformations, providing concretization in the sequence of coordinate frames of the reproduced portion (plot) of the signal of the main television program.

In its subsequent structure, the fourth block 26 of the selection of signals of time parameters is not significantly different from the first 23, second 24 and third 25 blocks of similar purpose. From the outputs of blocks 169, 170, 171, 172 of a threshold assessment of changes in the level of integrated signals, converted integrated signals, allowing

to identify the sections (intervals in the sequence of frames) of their maximum level are supplied to blocks 173, 174, 175, 176 for evaluating the parameters of the duration of the intervals in which the moments of occurrence (beginning), continuation (duration) and completion (end) of increases in the input level are specified in the sequence of frames signals with respect to the beginning (local time) of the user-specified transmission within the main program. The outputs of the generated control signals from the outputs of the blocks (173, 174, 175, 176) for estimating the interval duration parameters are connected to the blocks 177, 178, 179, 180 for the relative calculation of the interval duration corresponding to the maximum level of integrated signals of the result of multiplying undetected and delayed by time (p ₀ Tk + Tov) of the components of the brightness signal, sound accompaniment, the first and second color-difference signals of a television program. Other inputs of the indicated (177, 178, 179, 180) blocks are connected to the outputs 32 of the block 27 of the formation of the signals of the reference intervals and the local time signal that identifies the start of a user-defined transmission. The statistically averaged, current minimum, average and maximum values (range of values) of the signals of the duration of the advertising insert and repeated plots are compared in blocks (177, 178, 179, 180) of the relative calculation of the duration of the intervals of the fragments of the advertising insert with the calculated durations of the generated control signals obtained in blocks (173, 174, 175, 176) for estimating interval duration parameters. The result of comparisons is the limitation of the analyzed intervals. In the fourth block 181 of the formation of the output signal of the values of the time parameters, a comparison of the values of the signals of the time parameters received from the blocks (177, 178, 179, 180) of the relative calculation of the duration of the intervals of the fragments of the advertising insert is implemented and finally the control signals reflecting the coordinates of the signals of the advertising inserts in the frame sequence a signal of a controlled broadcast television program with respect to the start of a user-defined local time transmission. At the output 182 of the fourth block 181 of generating the output signal of the values of the time parameters, control signals are obtained that reflect the position of the signals of the advertising inserts and the replay of the signal portion of the main television program that precedes the signal of the fragment of the advertising insert after it is completed in the specified programs of interest to the user that correspond to the signals of individual programs broadcast television.

The control signals received in blocks 23, 24, 25, and 26 of the selection of signals of time parameters reflecting the specifics of the distribution and time parameters of the signals of fragments of advertising inserts within the total duration of the transmission selected by the subscriber (user) corresponding to a particular broadcast television program are input to the second 28 block temporary coordination for their hard pairing in time with respect to the beginning and completion of the local time of the transmission. At the same time, the duration of the programs selected by the subscriber corresponding to the used television programs is associated, with some approximation, with the duration of the accompanying processes of seamless conversion of the intervals occupied by such programs in the signals of each individual television broadcast program. Therefore, in the second block 28 of the time coordination, in addition, the necessary time offsets of the indicated control signals are carried out, taking into account the duration of the process of seamless conversion of audio and video signals corresponding to specific broadcasts in the used broadcast television programs.

The signals from the output of the insertion signal temporal identification block 21 identify the inputs of the first 29 block of temporal matching for hard pairing and time offset with respect to the beginning and completion of local time broadcasts selected by the subscriber from broadcast television programs used in the region. The time-coordinated signals of the time parameters are supplied from the corresponding blocks 28 and 29 to the first and second independent inputs of the block 31 of the relative evaluation of the signals of the time parameters. The third input of this block 31 receives local time signals. In block 31 of the relative assessment of the signals of time parameters, a comparison of the signals of time parameters obtained in the analysis of the instruction signals, data, metadata and lines of the subtitle accompanying the video stream and the signals of the time parameters obtained during the selective processing of the luminance components, the envelope of the soundtrack, and each of the color difference constituent parts of the signal of broadcast television programs specified by the subscriber. Based on the results of the comparison, the resultant signals are generated identifying the time parameters of commercial inserts in this broadcast of a specific broadcast television program and related addressing signals. The use of such allows seamless conversion of the signal corresponding to the transmission selected by the subscriber within the signal of a separate television program. From the first output of block 31, the resulting identification signals of temporal parameters of commercial inserts in this particular program broadcast television broadcasting and related addressing signals are fed to the control inputs of address storage unit 22 and playback unit 30. In accordance with these signals, a seamless rewriting of the selected transmission signal from the operational address storage unit to the archive address storage unit is implemented, in which the resulting resulting signals for identifying temporary parameters of commercial inserts are archived. Using these signals, it is also possible to extract from the signal of the main program and operational address storage of the advertising fragment accompanying this transmission for its reproduction, in the case of a user request. In parallel, the resulting identification signals for temporary parameters of commercial inserts are sent to the playback unit, stored and used to create user metadata associated with the archived signals of broadcast television programs.

In block 31 of the relative evaluation of the signals of the time parameters, the obtained values of the time parameters for each program are also averaged over time, for example, for 6 or more hours. Such averaged values of the signals of time parameters (USVP) corresponding to the used broadcast television programs are supplied to the corresponding inputs of the reference interval adjustment unit 19 and are used when generating the reference interval signals in the corresponding block 27.

The technical and economic effect can be obtained due to the hardware implementation and serial production of set-top boxes, which suppress the content undesirable for the subscriber.
