The present invention relates to broadcasting, and more particularly, to a method for separating and replacing commercial broadcasting separated from broadcasting.

In recent years, broadcasting services using various media such as cable broadcasting, internet broadcasting, and the like are being provided as well as over-the-air broadcasting. In order to expand and activate the base of various broadcast contents, the role of broadcasting in all fields such as sports, show entertainment, news reports, and culture is exploding. Broadcasting content will be resold in a variety of ways depending on the rights of broadcasting and broadcasting rights. In addition, broadcast contents are classified into online, offline, mobile, etc. according to the delivery method. Businesses in the sector will pay for their rights and royalties and purchase their programs.

In this case, broadcasting companies need to provide broadcasting contents separately for the companies that purchased the broadcasting rights under the contract. In reality, in case of live broadcasting, the real broadcasting such as commercial broadcasting mixed with advertisement broadcasting Broadcasting network). This is provided on the same terms as regular viewers and is provided in an unequal manner to operators paying for expensive content costs.

A general broadcast advertisement is an advertisement formed before and after a broadcast program (from the announcement of the broadcast program start date to the start of the broadcast program and from the end of the broadcast program until the end of the broadcast program end title) And post-commercial (commercial after the end of the program). In addition, the intermediate advertisement is an advertisement in which a corresponding program is interrupted between the start of one broadcast program and the end of one broadcast program. For example, in the case of sports broadcasts, the form of intensive interim advertising is now entering each time, before and after the end of the year. In addition to terrestrial broadcasters, IPTV, CATV, and other commercials have become more common.

In other words, a company purchasing content purchases broadcast content, but broadcasters transmit various commercials in addition to the broadcast (i.e., the broadcast program) to the provider. Therefore, There are many inconveniences to utilize. If the program is easily separated from the commercial, the operators who bought the program will be able to use only the necessary broadcasting services. However, broadcasters produce commercials and programs separately, but ultimately send them as one broadcast content to operators, so operators can easily separate commercials and commercials, replacing commercials with other content .

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is therefore an object of the present invention to provide a method for replacing commercials in broadcasts with other contents by distinguishing broadcasts from commercials.

In addition, the present invention is to provide a method of efficiently dividing the broadcasting and commercial broadcasting and reducing the processing load thereof.

Another object of the present invention is to provide a method of replacing advertisements in a broadcast which can distinguish advertisement broadcasts more efficiently by different analysis methods for commercial broadcasts according to types of broadcast contents.

According to an aspect of the present invention, there is provided a method of replacing an advertisement in broadcast contents received in real time, comprising: setting and maintaining alternative methods including an analysis method and an advertisement programming method according to each type of broadcast content; Extracting an alternative method corresponding to a type of a real-time broadcast to be analyzed; And analyzing the real-time broadcast according to the analysis method of the alternative scheme, and if the advertisement broadcast is recognized as an analysis result, replacing the advertisement broadcast with an alternative broadcast organized according to the alternative advertisement- There is provided a recording medium on which an advertisement replacement method and a program for performing the method are recorded.

Here, an analysis section is set as the analysis method, and only broadcast contents according to the analysis section of the real time broadcast can be analyzed.

In addition, when the advertisement is recognized during the real-time broadcast, the advertisement image may be used to recognize a future advertisement broadcast.

In addition, at least one of the types of the broadcast contents can recognize the advertisement broadcast by using the change of the noise according to the audio signal according to the real time broadcast.

In addition, when the noise is lower than a predetermined level as a result of the analysis of the audio signal, it is possible to determine whether the advertisement is started by comparing the broadcast images before and after the noise change.

A method of replacing an advertisement in broadcast contents received in real time, the method comprising: setting a threshold value using a noise value of an audio signal recognized as a main broadcast among real-time broadcasts to be analyzed; Measuring a noise value of an audio signal according to the real-time broadcasting at various times, and determining whether to start commercial broadcasting by determining whether the measured noise value is lower than the threshold value; And replacing the real-time broadcast with a preset substitute advertisement, and a method for replacing an advertisement in a broadcast, and a recording medium on which a program for performing the method is recorded Is provided.

Here, it is possible to determine whether or not the advertisement is started by comparing the broadcast images before and after the point at which the noise starts to fall below the threshold value.

In addition, when the advertisement is recognized during the real-time broadcasting, the step of storing the advertisement image capturing the image at the start of the commercial broadcasting may further include the step of analyzing the noise of the audio signal of the real- If the advertisement is recognized, the advertisement image can be used to determine whether or not the advertisement is broadcast.

According to the present invention, it is possible to replace the broadcast and the commercial broadcast with respect to the broadcast content transmitted in real time, thereby replacing the advertisement in the broadcast with another advertisement desired by the business operator. Thus, Differentiated content will be produced and opportunities for broadcast advertising can be provided to the advertising market in an inexpensive manner.

In addition, according to the present invention, processing load can be reduced as compared with a general image analysis method by using an audio signal in distinguishing between broadcasting and commercial broadcasting.

In addition, according to the present invention, it is possible to distinguish advertisement broadcasting more efficiently by different analysis methods for commercial broadcasting according to the type of broadcasting contents, and it is possible to provide an alternative advertisement suitable for the advertisement broadcasting.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that the invention is not intended to be limited to the particular embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout the specification and claims. The description will be omitted.

FIG. 1 is a block diagram schematically illustrating an overall system for a service that replaces an advertisement in a broadcast according to an embodiment of the present invention. Referring to FIG.

1, the overall system according to the present embodiment includes a broadcaster 10, a content provider 30, an advertiser 50, and a viewer 70. [

The broadcaster 10 is a broadcast provider that provides broadcast content as real-time broadcasts. The content provider 30 pays a royalty to the broadcaster 10 and purchases the broadcast content and broadcasts the broadcast content to the viewers 70 again . In particular, the content provider 30 replaces the advertisement broadcast included in the broadcast content with the substitute advertisement requested by the advertiser 50 and provides the same to the viewer 70.

Hereinafter, a method of replacing an advertisement in a broadcast performed by the content provider 30 will be described in detail.

FIG. 2 is a flowchart illustrating an advertisement replacement process in a broadcast according to an embodiment of the present invention. FIG. 3 is a diagram illustrating a configuration of a broadcast content having a common intermediate advertisement, Is a table illustrating information on an alternative method for each type of broadcast content according to the type of broadcast content.

Referring to FIG. 2, an alternative method including an analysis method and an advertisement programming method for each type of broadcasting contents is set (S10).

Referring to FIG. 3, in the case of a broadcast content in which an intermediate advertisement is inserted, an advertisement is broadcast in the middle of broadcasting after the pre-broadcast advertisement is started. It is necessary to be able to recognize the time (T2, T4, etc.) at which the advertisement is broadcast and the time at which the broadcast is broadcast (T3, T5, etc.) In order to efficiently recognize each of the viewpoints and the patterns in which the respective commercial broadcasts are inserted, an alternative method is set for each type of broadcast contents according to the present embodiment.

In many cases, the manner in which the advertisement is inserted for each type of broadcast content is different. Referring to FIG. 4, for example, in the case of a sports broadcast broadcast, in the case of a baseball game, an advertisement for about one minute is broadcast each time the game ends, and in the case of a football game, two advertisements are broadcast for about ten minutes after the first half. Therefore, it is possible to organize advertisement to be replaced by setting an advertisement organizing method according to the type of broadcast contents.

The analysis method of the alternative method can be set differently according to the analysis method for distinguishing the commercial broadcasting from the main broadcasting type for each type of broadcasting contents. The analysis method is as to how to analyze the video or audio, An analysis section for determining which broadcasting section is to be analyzed may be set.

For example, if the broadcast content is relayed to a baseball game, it is possible to distinguish the commercial broadcast from the main broadcast by analyzing the audio signal among the signals according to the real-time broadcast. After 10 minutes from the start of the broadcast (refer to FIG. 2, 10 minutes after T1 or 10 minutes after T3, etc.), the analysis of the audio signal can be started. This is to reduce the processing load due to analysis of unnecessary audio signals or video signals.

Referring again to FIG. 2, when the type of real-time broadcasting is recognized, an analysis method and an advertisement programming method according to the type are extracted (S20). Here, the type of the real-time broadcast may be input by the administrator, but according to another example, the broadcast type may be directly recognized by analyzing the advertisement or the main broadcast image before the start of the broadcast program. Since the information (title, etc.) about the broadcast program is usually displayed on one side of the screen (upper right side) in the advertisement before the start of the broadcast program, the type can be recognized using this information. Or by analyzing the video itself of the broadcast or analyzing audio (using speech recognition technology).

In step S30, the viewer 70 analyzes the real-time broadcasting according to the extracted analysis method to recognize the commercial broadcasting in step S30. In step S40, the viewer 70 replaces the commercial broadcasting with the alternative broadcasting program organized in accordance with the advertisement programming method. So that the user can view the alternative broadcast included in the advertisement broadcast.

According to the present embodiment, in a state in which the substitute advertisements are set in advance, the substitute advertisements can be easily organized in real time using the type of broadcast content received. In addition, the analysis method suitable for the type of broadcast contents can reduce the processing load due to the analysis of the image or audio and increase the accuracy thereof.

Although not shown in the drawing, according to an example, if an advertisement is recognized during real-time broadcasting, an advertisement image that captures an image at a time when the advertisement is started can be stored. The stored advertisement image can be used for recognition of the advertisement broadcast later. For example, in the case of a baseball broadcast, about 20 times or more commercial broadcasting is provided. In general, the same advertisement is often broadcast a plurality of times. Therefore, It becomes easy to recognize the commercial. With reference to Fig. 2, for example, it is possible to easily recognize the start of the same advertisement during T3 to T4 using the advertisement image captured at the time point T2.

In general, image analysis techniques are widely used in the way of distinguishing between broadcasting and commercial broadcasting. For example, it is possible to distinguish between broadcasting and commercial broadcasting using the presence of a specific phrase, image, etc. displayed on one side of the image. As an easy example, in most intermediate advertisements, the phrase related to the broadcast is displayed on the upper right corner. The image can be analyzed and the advertisement can be distinguished from the broadcast using the existence of the corresponding phrase.

Analysis of audio signal can be faster than analysis of image. In the present invention, an analysis method of an audio signal is proposed to improve the analysis processing speed and to improve the accuracy for distinguishing between broadcasting and commercial broadcasting.

5 is a flowchart illustrating a process of replacing an advertisement image by analyzing an audio signal according to an embodiment of the present invention.

Referring to FIG. 5, noise of an audio signal is measured (S510), and it is determined whether the value is below a threshold (S520).

Generally, in the case of sports broadcasting, the broadcast includes a high numerical noise in the audio signal as compared with commercial broadcasting. In the case of baseball or soccer, there is a lot of noise in the audio signal according to the broadcasting because the game is played outdoors and the crowd cheers. In this embodiment, by using this point, the main broadcasting and the commercial broadcasting are distinguished according to the amount of noise.

That is, a value corresponding to the noise level measured in the broadcast (for example, a value obtained by subtracting a constant value from the lowest folded or average noise value measured in this broadcast) is set as a threshold value, When an audio signal having a noise value is received, the advertisement may be recognized as being broadcast at that time. Here, the predetermined threshold value may be a predetermined fixed value, or any value may be set according to the type of broadcast content. According to another embodiment, the threshold value may be set using the noise figure measured in the broadcasting as described above. That is, when the broadcast starts, the noise may be measured for a predetermined time (e.g., one minute), and a value obtained by subtracting a certain value from the average value or the lowest measured value may be set as a threshold value.

If the noise value of the measured audio signal is greater than or equal to the threshold value, it is recognized that the broadcast is broadcast, and the broadcast received in real time is maintained (S530).

In order to increase the accuracy, in the present embodiment according to an exemplary embodiment, if the audio signal is recognized as an advertisement broadcast, the image analysis is further performed (S540), and it is determined whether or not the image is an advertisement image (S550).

Here, as an image analysis method according to an example, it is possible to determine whether the advertisement is started by comparing one or more broadcast image images before and after a noise change occurs. For example, it can be recognized that commercial broadcasting starts if the difference between the before and after images of the above point (noise change) is larger than a certain level (more than 50%).

According to another example, if an audio signal having a noise equal to or less than a threshold value is recognized, the image at that point of time and the above-mentioned advertisement image (captured image at the time point recognized as commercial broadcast) . If they are not equal to each other, the advertisement may be determined by analyzing the image itself at that point in time or by comparing images before and after the point of time as described above.

According to another example, the initial image of the broadcast content (i.e., the initial images after the start of the broadcast program) is analyzed to recognize text such as [offer] or [commendation] The displayed text is used for recognizing the advertisement image. Generally, in the case of TV broadcasting, information on advertisers is displayed on the screen at the beginning of the broadcasting program. For example, when a beverage advertisement is inserted, the information about the advertiser requesting the beverage advertisement is displayed together with the phrase [offer] or [sponsorship] on one side of the image. And extracts information on advertisers by analyzing an initial image of a broadcast program using the extracted information. The information about the extracted advertiser can be used to grasp the information about the advertisement contents that the advertisers mainly advertise and can be used for identifying the advertisement image in the broadcast contents. For example, if the company A is an advertiser, since the company mainly grasps the advertisement content a, the advertisement image in the broadcast program can be accurately and quickly recognized using the images of the advertisement content a.

According to the above-described embodiments, it is possible to analyze the audio signal only or to perform the image analysis only at a specific point in time (at which noise is measured below a threshold value), thereby reducing the analysis processing load required for recognizing commercial broadcasts and improving the speed have. In addition, more accurate analysis may be performed by using the advertisement image and / or the information about the identified advertiser.

If it is determined that the image is not an advertisement image, the process proceeds to S510. If the image is determined to be an advertisement image, the corresponding advertisement image is replaced with a replacement image (S560).

The above-described method of replacing an advertisement in a broadcast according to the present invention can be implemented as a computer-readable code on a computer-readable recording medium. The computer-readable recording medium includes all kinds of recording media storing data that can be decoded by a computer system. For example, it may be a ROM (Read Only Memory), a RAM (Random Access Memory), a magnetic tape, a magnetic disk, a flash memory, an optical data storage device, or the like. In addition, the computer-readable recording medium may be distributed and executed in a computer system connected to a computer network, and may be stored and executed as a code readable in a distributed manner.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that various modifications and changes may be made.
