Hereinafter, a specific embodiment of the broadcast and advertisement content monitoring automation system of the present invention will be described with reference to FIGS. 1 to 5. However, this is only an exemplary embodiment and the present invention is not limited thereto.

In describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of a user or an operator. Therefore, the definition should be made based on the contents throughout the specification.

The technical spirit of the present invention is determined by the claims, and the following embodiments are merely means for effectively explaining the technical spirit of the present invention to those skilled in the art to which the present invention pertains.

1 is a view showing the configuration of a broadcast and advertising content monitoring automation system according to an embodiment of the present invention. Here, the broadcasting and advertising content monitoring automation system may be applied to, for example, terrestrial broadcasting, DMB broadcasting, cable broadcasting, IPTV broadcasting, and radio broadcasting. However, the present invention is not limited thereto and may be applied to various other broadcasts (for example, broadcasts not currently commercialized or broadcasts to be developed in the future).

Referring to FIG. 1, the broadcasting and advertising content monitoring automation system 100 includes a unique information hiding device 102, a regional recording device 104, and a broadcasting and advertising content monitoring device 106.

The unique information hiding apparatus 102 receives a broadcast and advertisement content (eg, video content or sound content), and inserts a hidden signal into the input broadcast and advertisement content. At this time, the hidden signal is generated using the unique information of the broadcast and advertisement content (for example, copyright information, broadcast time, broadcast review number, advertisement review number, etc.) of the corresponding content. Thereafter, the unique information concealment apparatus 102 transmits each broadcast and advertisement content having the hidden signal inserted therein to the broadcasting station 103. Although the unique information concealment apparatus 102 has been described in a separate configuration from the broadcast station 103, the present invention is not limited thereto, and the unique information concealment apparatus 102 may be included in the broadcast station 103.

Region recording apparatus 104 is installed in each region (for example, Gyeonggi-do, Gangwon-do, Chungcheongnam-do, Chungcheongbuk-do, Jeollanam-do, Jeollabuk-do, Gyeongsangnam-do, Gyeongsangbuk-do, Jeju-do, etc.), recording the broadcast and advertising content transmitted from the broadcasting station 103 do. In this case, the region-specific recording device 104 may record broadcast and advertisement content at a predetermined time unit (for example, 24 hours), and the broadcast and advertisement content recorded at a predetermined time unit (hereinafter, referred to as a 'recording broadcast'). To the broadcast and advertising content monitoring device 106. In this way, by recording the broadcast and advertising content transmitted from the region through the region-specific recording device 104, it is possible to monitor the broadcast and advertising content nationwide.

The broadcast and advertising content monitoring device 106 receives the recorded broadcasts from the recording devices 104 in each region, and then detects the hidden signals in the received recorded broadcasts and separates the recorded broadcasts by the sections having the same hidden signals. Save it. Here, since the hidden signal includes unique information of broadcast and advertisement content, a section having the same hidden signal becomes a section in which one same broadcast and advertisement content that is distinguished from other broadcast and advertisement contents is aired. Therefore, when the recorded broadcast is divided into sections having the same hidden signal, the recorded broadcast can be separated by each broadcast and advertisement content. That is, since the recording broadcast is, for example, a 24-hour broadcast, the recording broadcast includes a plurality of broadcast and advertisement contents. At this time, if the recorded broadcast is divided into sections having the same hidden signal, the recorded broadcast can be separated for each broadcast and advertisement content. Hereinafter, the broadcast and advertisement content separated from the recorded broadcast is referred to as recorded broadcast and advertisement content.

The broadcast and advertisement content monitoring device 106 stores recorded broadcast information including a broadcast time and a broadcast duration of the corresponding recorded broadcast and advertisement content for each recorded broadcast and advertisement content. Here, the broadcast time of the recorded broadcast and advertising content indicates the time that the broadcast and the advertising content is broadcasted and started broadcasting, and the broadcast duration of the recorded broadcast and the advertising content is the time that the actual broadcast of the recorded broadcast and advertising content continued Indicates.

In addition, the broadcast and advertisement content monitoring device 106 stores original broadcast information including a scheduled broadcast time and a scheduled broadcast duration of the original broadcast and advertisement content. Here, the original broadcast and advertisement content refers to a state before the recorded broadcast and advertisement content is transmitted by the broadcasting station 103. The scheduled broadcast time of the original broadcast and the advertisement content indicates the scheduled time for the original broadcast and the advertisement content to be broadcast, and the scheduled broadcast duration of the original broadcast and the advertisement content is to be continued for the broadcast of the original broadcast and advertisement content. Represents the scheduled time.

In this case, the broadcast and advertising content monitoring device 106 compares the broadcast time and the broadcast duration of the recorded broadcast and advertisement content with the scheduled broadcast time and the scheduled broadcast duration of the original broadcast and the advertisement content, and the recorded broadcast and advertisement It is possible to check whether the content is properly aired by the scheduled broadcast duration of the original broadcast and advertisement content at the scheduled broadcast time of the original broadcast and advertisement content.

Hereinafter, the configuration and operation of the unique information concealment device 102, regional recording device 104, and broadcasting and advertising content monitoring device 106 will be described in detail.

Referring to FIG. 2, the unique information hiding apparatus 102 includes an insertion strength calculator 111 for an image, an insertion strength calculator 113 for a sound, a hidden signal generator 115, a hidden signal inserter 117, And a content transmitter 119.

The unique information hiding apparatus 102 may preferentially perform digital processing necessary for inserting a hidden signal into the input broadcast and advertisement contents when receiving the broadcast and advertisement contents (that is, the image content or the acoustic content). For example, when image content or sound content is received in the form of a multimedia file, the unique information hiding apparatus 102 separates the image content or sound content in the form of a digital file into image frame units or sound frame units, respectively. When the video content or the audio content is received in the form of a Digibeta tape, the unique information hiding apparatus 102 inputs an HD-SDI (High Definition Serial Data Interface) signal to the Digibeta tape, and lossless compression. After converting the format into a digital file format, the video content or sound content in the digital file format is separated into video frame units or sound frame units, respectively.

The image insertion strength determiner 111 determines an insertion strength (hereinafter, referred to as an image insertion strength) of a hidden signal to be inserted into the image content using the input image content. In this case, the image insertion strength determiner 111 may determine the image insertion strength for each image frame of the image content. The image insertion strength determiner 111 may determine the image insertion strength of each image frame through, for example, Equation 1 below.

Equation 1

Here, V _th (i, j) represents the image insertion intensity of the corresponding video frame, and V _L (i, j) and M _L (i, j) represent (i, The dispersion value and average value in the position of j) are shown, respectively. α represents a weight and can be set to 2 or 3, for example. However, the value of α is not limited thereto, and may be set to an appropriate value in consideration of the image quality of the image content and the robustness of detecting the hidden signal. W (M _{L (i, j)} ) represents a weight by the average value M _L (i, j) of the local region of the variance value V _L (i, j) of the video frame. At this time, the weight W is based on Equation 2 below.

Equation 2

Here, log _β may be log _e or log ₁₀ .

The sound insertion strength determiner 113 determines the insertion strength (hereinafter, referred to as "sound insertion strength") of the hidden signal to be inserted into the sound content using the input sound content. In this case, the sound insertion strength determiner 113 may determine the sound insertion strength for each sound frame of the sound content.

For example, the sound insertion strength determiner 113 converts each sound frame of the acoustic content into a frequency space, and has a first moment and a second moment for each frequency band with respect to an amplitude component of each sound frame converted into the frequency space. After sequentially calculating, the sound insertion strength is determined by calculating the difference of the second moments between adjacent sound frames. This will be described in detail below.

First, the sound insertion strength determiner 113 may obtain a first moment for an amplitude component of each sound frame through Equation 3 below.

Equation 3

Where Mo _1st (i) represents the first moment for the amplitude component of the acoustic frame, F (i) represents the amplitude component of the acoustic frame, i represents the frequency band of the amplitude component, and N represents the acoustic Indicates the number of amplitude components in the frequency band of the frame.

Next, the sound insertion strength determiner 113 may obtain the second moment for the amplitude component of each sound frame through the following equation (4).

Equation 4

Here, Mo _2nd (i) represents the second moment with respect to the amplitude component of the corresponding sound frame.

Next, the sound insertion strength determining unit 113 determines the sound insertion strength by calculating the difference between the second moments of two sound frames neighboring each other through Equation 5 below.

Equation 5

Here, A _th (i) represents the sound insertion strength of the corresponding sound frame. In this case, the sound insertion strength determiner 113 may calculate the sound insertion strength by adding a separate weight.

The hidden signal generator 115 generates a hidden signal by using the unique information of the input broadcast and advertisement content. That is, the hidden signal generator 115 generates a hidden signal using unique information such as a broadcast review number and an advertisement review number that are uniquely assigned to only the input broadcast and advertisement content. Here, the unique information of the broadcast and advertising content may be provided from a unique information management database (not shown).

For example, the hidden signal generator 115 may reconstruct the unique information of the inputted broadcast and advertisement content so that the hidden signal can be restored even if distortion or deformation occurs in the broadcast and advertisement content into which the hidden signal is inserted. Message encoding is performed using an error correction code such as a Solomon (LD) code or a Low Density Parity Check (LDPC) code.

Next, the hidden signal generator 115 generates a pseudo noise signal having an auto correlation property by using the unique information of the message-encoded broadcast and advertisement content as a seed value. Here, the pseudo irregular signal refers to a signal in which a value of 1 or -1 is randomly arranged according to the seed value.

Next, the hidden signal generator 115 shuffles the generated pseudo-random signal to generate a unit hidden signal pattern. That is, the hidden signal generator 115 shuffles the generated pseudo-random signal to be randomly located within the inputted broadcast and advertisement content to generate a unit hidden signal pattern. This is because if the generated pseudo-random signal is not randomly located in the input broadcast and advertisement content, the broadcast and advertisement content monitoring device 106 may cause a loss beyond the error correction range when detecting the hidden signal. Accordingly, the shuffling randomizes a position of the generated pseudo-random signal to be inserted into the broadcast and advertisement content.

Here, when the input broadcast and advertisement content is video content, the hidden signal generator 115 does not exceed the size of the unit hidden signal pattern to exceed 1/4 of the video content. For example, the hidden signal generator 115 prevents the horizontal and vertical lengths of the unit hidden signal patterns from exceeding 1/2 of the horizontal and vertical lengths of the image content (or, more specifically, the image frame). This is for the purpose of easily predicting and recovering the geometric deformation in the broadcast and advertising content monitoring apparatus 106 when a geometric deformation occurs in the image content into which the hidden signal is inserted. That is, when the size of the unit hidden signal pattern is generated to be 1/4 or less of the video content, the unit hidden signal pattern may be periodically inserted into the video content, and thus even if geometric deformation occurs in the video content. It can be easily predicted and recovered.

In addition, when the input broadcast and advertisement content is acoustic content, the hidden signal generation unit 115 does not allow the length of the unit hidden signal pattern to exceed 1/2 of the monitoring detection unit time of the acoustic content. For example, when the monitoring detection unit time of the acoustic content is 1 second, the length of the unit hidden signal pattern does not exceed 1/2 of the length of 1 second of the acoustic content. In detail, in the case of sound content having a sampling period of 44100 Hz, when 43 sound frames are separated in units of 1024 Hz, 43 sound frames per second are generated. At this time, the unit hidden signal pattern is periodically inserted in units of 21 sound frames. In this case, even if a geometrical deformation occurs in the acoustic content, the periodic characteristic of the unit hidden signal pattern can be easily predicted and restored.

Next, the hidden signal generation unit 115 generates the hidden signal by tiling the unit hidden signal pattern to the size of the input broadcast and advertisement content.

The hidden signal inserting unit 117 inserts the hidden signal into the input broadcast and advertisement content. When the input broadcast and advertisement content is video content, the hidden signal insertion unit 117 may insert the hidden signal into the video content by using Equation 6 below.

Equation 6

Here, Video '(i, j) represents the video content into which the hidden signal is inserted, Video (i, j) represents the video content to be input, V _Info (i, j) represents the hidden signal, and V _th ( i, j) represents the image insertion intensity.

When the input broadcast content is sound content, the hidden signal insertion unit 117 may insert the hidden signal into the sound content using Equation 7 below.

Equation 7

Here, Audio '(i) represents the acoustic content into which the hidden signal is inserted, Audio (i) represents the acoustic content to be input, A _Info (i) represents the hidden signal, and A _th (i) represents the sound insertion intensity. Indicates.

The content transmitter 119 transmits the broadcast and advertisement content in which the hidden signal is inserted, to the broadcasting station 103. On the other hand, when the unique information hiding apparatus 102 is included in the broadcasting station 103, the content transmitter 119 is not necessary.

According to an embodiment of the present invention, since a hidden signal can be inserted into broadcast and advertising content in a very short time unit (for example, in a video frame unit for video content and in a second for sound content), Secondary monitoring can be performed on advertisement content having a short duration of less than 15 seconds, thereby improving the precision of monitoring.

In addition, since the hidden signal is concealed and inserted into a broadcast or advertising content in an invisible or inaudible form, the general viewer or listener cannot confirm whether or not the hidden signal is inserted, thus affecting the viewing environment or listening environment. Do not give.

3 is a diagram illustrating a configuration of a recording apparatus for each region according to an embodiment of the present invention.

Referring to FIG. 3, the region-specific recording apparatus 104 includes a tuner unit 121, a recording unit 123, a temporary storage unit 125, and a recorded content transmission unit 127.

The tuner unit 121 selects a predetermined channel (for example, a TV channel or a radio channel) according to a manager's command, and then receives the broadcast content transmitted from the broadcasting station 103 through the selected channel.

The recording unit 123 records the received broadcast and advertisement content at predetermined time units (for example, 24 hours). The recording unit 123 records when the received broadcast content is video content, for example, in the form of Moving Picture Experts Group-Transport Stream (MPEG-TS), and when the received broadcast and advertisement content is acoustic content, For example, recording in the form of pulse code modulation (PCM).

The temporary storage unit 125 stores the recorded broadcast and advertisement content, that is, the recorded broadcast, on a predetermined time basis. In this case, the temporary storage unit 125 may store, for example, one week of recorded broadcasts.

The recorded content transmitter 127 periodically transmits the recorded broadcast to the broadcast and advertisement content monitoring device 106. For example, the recorded content transmitter 127 may transmit the 24 hours of the recorded broadcast data to the broadcast and advertisement content monitoring device 106 at a predetermined time every day based on the screen adjustment time of 5 am. In this case, the recording content transmitter 127 may include the region information for identifying the corresponding region and the channel information for identifying the channel from which the corresponding recording broadcast is transmitted to the recording broadcast.

Here, when the recorded broadcast is not transmitted due to a communication problem, the recorded content transmitter 127 retransmits the corresponding recorded broadcast in response to a request for retransmission of the broadcast and advertisement content monitoring device 106. Here, when the communication problem is not solved for a predetermined time (for example, 24 hours), the recording device 104 for each region may transmit a notification message to an administrator's e-mail or a mobile terminal to take an action.

When the transmission completion signal is transmitted from the broadcast and advertisement content monitoring device 106, the recorded content transmitter 127 deletes the corresponding recorded broadcast item from the temporary storage unit 125. In this case, since the temporary storage unit 125 stores and deletes the recorded broadcast data for one day every day, it is not necessary to continuously secure the space for storing the recorded broadcast, thereby reducing the system construction cost.

According to an embodiment of the present invention, since the recording device 104 for each region is installed in each region, the broadcasting and advertisement contents broadcast only in the region can also be monitored, so that terrestrial broadcasting, radio broadcasting, cable broadcasting, etc. Broadcasting and advertising content monitoring.

Referring to FIG. 4, the broadcast and advertising content monitoring device 106 includes a recorded content receiver 131, a hidden signal detector 132, a matching registration manager 133, a web server 134, and a database 135. do. Here, the database 135 includes a recorded broadcast and advertisement content database 135-1 and a matching broadcast information database 135-2.

The recorded content receiving unit 131 receives a recorded broadcast from the recording apparatus 104 for each region installed in each region. In this case, the recording content receiver 131 may simultaneously receive the recording broadcasts from the recording devices 104 for each region. For example, when the region-specific recording device 104 in the region A and the region-specific recording device 104 in the B region simultaneously transmit the recording broadcast, the recording content receiving unit 131 sets the receiving channel for each of the recording broadcasts. Can receive water at the same time.

The recording content receiving unit 131 may include a buffer (not shown) for temporarily storing the received recording broadcast. At this time, the recorded content receiving unit 131 may store the received recorded broadcasts in a buffer (not shown) by distinguishing each region, channel, and date.

The recording content receiving unit 131 transmits a retransmission request signal of the corresponding recorded broadcast to the regional recording device 104 when the corresponding amount of the recorded broadcast is not transmitted from the predetermined regional recording device 104. That is, the recording apparatus 104 for each region transmits, for example, 24 hours of recorded broadcasts at a predetermined time (for example, 5 am). At this time, the recorded content receiving unit 131 checks whether the corresponding amount of the recorded broadcast is transmitted from the recording devices 104 for each region. As a result of the check, when the corresponding amount of the recorded broadcast is not transmitted from the predetermined region-specific recording apparatus 104, the recorded content receiver 131 transmits a retransmission request signal to the region-specific recording apparatus 104.

The hidden signal detector 132 detects a hidden signal (ie, unique information) in the received recorded broadcast. Thereafter, the hidden signal detection unit 132 separates the recorded broadcast broadcasts by the same section of the received hidden broadcast broadcast signals. This will be described with reference to FIG. 5. 5 is a diagram illustrating a recording broadcast.

Here, the recording broadcast consists of a plurality of broadcast and advertising content, such as drama 1, advertisement 1, advertisement 2, drama 2, advertisement 3, news 1, .... The unique information of the broadcast and advertisement contents is inserted into the hidden signal for each broadcast and advertisement content. For example, drama 1 is a 101, ad 1 is b 101, ad 2 is b 102, drama 2 is a 102, ad 3 is b 103, and news 1 is c 101. It is in the inserted state as a hidden signal. Therefore, when the hidden signal detection unit 132 detects the hidden signal from the recorded broadcast, the recorded broadcast can be separated by the same section where the hidden signal is the same, in which case the recorded broadcast is divided into each broadcast and advertisement content unit. Will be separated.

The matching registration manager 132 stores the broadcast and advertisement contents separated from the recorded broadcast, that is, the recorded broadcast and the advertisement contents in the recorded broadcast and the advertisement content database 135-1. In this case, the broadcast and advertisement content monitoring apparatus 106 stores the recorded broadcast and advertisement contents, whereby it is possible to verify whether the monitoring result is correct.

The matching registration manager 132 matches the recorded broadcast information of the corresponding recorded broadcast and the advertisement content with the original broadcast information of the original broadcast and the advertisement content, and stores the matching broadcast information database 135-2 in the matching broadcast information database 135-2. .

Here, the recorded broadcast information includes a broadcast time and a broadcast duration of the corresponding recorded broadcast and advertisement content. The original broadcast and advertisement content refers to a state before the corresponding recorded broadcast and advertisement content is transmitted by the broadcasting station 103, and the original broadcast information includes a scheduled broadcast time and a scheduled broadcast duration of the original broadcast and advertisement content.

Table 1 is a table showing a state in which the recorded broadcast information of the recorded broadcast and the advertisement content and the original broadcast information of the original broadcast and the advertisement content are matched and stored in the matching broadcast information database according to an embodiment of the present invention.

Table 1

Recorded broadcast and advertising content	Recording broadcast information		Original broadcast information
Recorded broadcast and advertising content	Airtime	Airing duration	Scheduled airtime	Scheduled air duration
Drama 1	2010.12.31.22:00	2010.12.31.22:00~23:05	2010.12.31.22:00	2010.12.31.22:00~23:05
Ad 1	2010.12.31.23:05:05	2010.12.31.23:05:05~23:05:14	2010.12.31.23:05:05	2010.12.31.23:05:05~23:05:15
...	...	...	...	...

Referring to Table 1, it can be seen that in the recorded broadcast and advertisement content, drama 1 matches the recorded broadcast information (airtime and airtime duration) with the original broadcast information (scheduled airtime and scheduled airtime duration). On the other hand, the advertisement 1 only matches the broadcast time of the recorded broadcast information and the scheduled broadcast time of the original broadcast information, and it can be seen that there is a difference of 1 second between the broadcast duration of the recorded broadcast information and the scheduled broadcast duration of the original broadcast information. have.

The web server 134 provides a monitoring result of the broadcasting and advertising contents to the user through a web page when a user (for example, a broadcasting and advertising contents producer) accesses and requests a monitoring result of the broadcasting and advertising contents. . In this case, the web page may display the recorded broadcast information and the original broadcast information of the corresponding broadcast and advertisement content, respectively, and may indicate whether the recorded broadcast information and the original broadcast information match. In this case, the user has properly broadcasted the corresponding broadcast and advertisement content for a predetermined time (that is, the scheduled broadcast duration of the original broadcast information) at a predetermined time (that is, the scheduled broadcast time of the original broadcast information). You can check whether or not at a glance. In addition, the web server 134 may provide a corresponding web page so that a user may search the monitoring result of the broadcasting and advertising content by each broadcasting and advertising content, by date, and by channel.

Meanwhile, the web server 134 may display a representative key frame on the web page for the broadcasting and advertisement content for which the user requests the monitoring result. For example, the web server 134 extracts the recorded broadcast and advertisement content corresponding to the broadcast and advertisement content that requested the monitoring result from the recorded broadcast and advertisement content database 135-1, and then extracts the recorded broadcast and advertisement content from the extracted broadcast and advertisement content database. The first image frame may be extracted and displayed on a web page as a representative key frame of the broadcast and advertisement content. In this case, the user can view the broadcast and advertisement contents as an image image, so that it is easy to distinguish each broadcast and advertisement contents.

According to an embodiment of the present invention, the user can automatically determine whether the broadcast and the advertisement content is properly aired for a predetermined time at a predetermined time for each broadcast and the advertisement content. This can improve the accuracy of the monitoring and reduce the time required for monitoring.

Although the present invention has been described in detail with reference to exemplary embodiments above, those skilled in the art to which the present invention pertains can make various modifications to the above-described embodiments without departing from the scope of the present invention.
