According to another exemplary embodiment of the present invention, the detection condition D / B 150 may be implemented in a form included in a program code for implementing each means constituting the content operation server 100, whereby the present invention It is not limited.

The advertisement data includes image data or video data displaying an advertisement image (or advertisement shape) in a rectangular area.

According to an exemplary embodiment of the present invention, the advertisement data may include image data or video data displaying an advertisement image (or advertisement shape) of the rectangular area.

According to another exemplary embodiment of the present invention, the advertisement data may include image data or video data including an advertisement area displaying the advertisement image (or advertisement shape) and a transparent region in which the advertisement image (or advertisement shape) is not displayed. It may include.

The advertisement display condition may include any one of a geometrical condition and a palette configuration condition capable of effectively displaying the advertisement data in the rectangular area.

For example, when the advertisement data is composed of an advertisement region and a transparent region, and the geometry of the advertisement region is an ellipse, the advertisement display condition is that the advertisement data is displayed when the geometry of the advertisement region object is an ellipse. It may contain a condition to display on the area object.

May include a condition to display the advertisement data on the advertisement region object.

Here, the advertisement display condition is a priority advertisement selection condition for determining advertisement data to be preferentially displayed on an advertisement region object, and the geometry and palette configuration of the advertisement region object to display the advertisement data is limited by the advertisement display condition. It never happens.

The video content is composed of video data and audio data whose playback time is synchronized, and the video data is composed of M (M> 1) video frames including a predetermined number of pixels in a horizontal / vertical direction. The video data may include various video frames. For example, if the video content complies with the MPEG standard, the video frame may include an I-frame, a P-frame, and a B-frame.

Referring to FIG. 1, the content operation server 100 determines a geometry condition and a palette configuration condition for detecting an advertisement region object for displaying advertisement data from video data of video content. The detecting condition storing means 105 may be stored in the form. The geometry condition and the palette composition condition may be stored in the form of program code for implementing each means constituting the content operation server 100.

The geometry condition is a circle consisting of an N-angle, a center point and a radius of a boundary line of an area divided based on the hue / saturation displayed in the video data of the video content. And a condition for determining whether it matches a geometry of an ellipse consisting of a center point, a long radius, and a short radius.

For example, the geometrical condition is that a boundary line of a region divided based on the hue / saturation displayed in the video data of the video content is a straight line, and the lines connecting the straight lines are triangular, quadrangular or N-angled. It may include condition information for determining whether it corresponds to the geometry of one figure.

Alternatively, the geometrical condition is a closed curve connecting a boundary line of a region divided based on the hue / saturation displayed in the video data of the video content, and the closed curve corresponds to the geometric structure of one of circles and ellipses.

For example, the palette configuration condition may include a condition for determining an object corresponding to the geometry as an advertisement area object when the number of colors in the geometry of the object detected through the geometry condition is less than 10. . The limit of the number of colors within the preset number is to prevent the discrimination of the advertisement content displayed on the advertisement area object from being excessively large in the number of colors in the advertisement area object.

The palette configuration condition may include a condition for determining an object corresponding to the geometry as an advertisement area object when an average value of chroma values in the geometry detected through the geometry condition is smaller than a predetermined reference saturation value. can do. The limit of the average value of the saturation value within the reference saturation value is to prevent the color expression power of the advertisement content displayed on the advertisement region object from being subtracted because the color in the advertisement region object is too close to the primary color.

In addition, the palette configuration condition is an advertisement region object when the object corresponding to the geometry is formed when the deviation of the RGB values between the colors in the geometry detected through the geometry condition is within a preset deviation and is made of similar color. It may include a condition to determine. The limiting of the color in the geometric structure to a similar series of colors is for determining advertisement data for improving the discrimination in the color series of the advertisement region object.

Referring to FIG. 1, the content operation server 100 detects an advertisement region object from the video D / B 160 and extracts video content to display advertisement data, and the video. Advertising area object detecting means (115) for reading the video data of the content and detecting an advertising area object corresponding to at least one of the geometrical condition and the palette configuration condition; and a description of the geometric structure of the detected advertising area object. And an object structure reading means 120 for determining a geometry deformation value from the set reference geometry, and reading the geometry deformation value based on any singularity inside / outside the video reproduction area to determine the advertisement area object. The length of the side corresponding to the geometry has a larger value opposite the singularity than the singularity direction or the advertisement Perspective value checking means 125 may be further provided to determine whether the curvature corresponding to the geometry of the area object includes a perspective value having a larger value in the direction opposite to the singularity than the singularity direction.

The content extracting unit 110 detects an advertisement region object among the video contents stored in the video D / B 160 to determine one video content to display advertisement data, and extracts it from the video D / B 160. The advertisement area object detecting unit 115 reads video data of the moving image content and detects an advertisement area object satisfying at least one geometrical condition among the geometrical conditions stored in the detection condition D / B 150.

The advertisement region object detecting unit 115 performs hue / saturation from the m-th video data corresponding to the m-th (1 <= m <= M) video frame among the M (M> 1) video frames included in the video content. A value is extracted and the boundary line of the area divided based on the hue / saturation is identified by reading the extracted hue / saturation value. For example, if the m-th video data is an I-frame composed of RGB (Red, Green, Blue) palettes, the color / saturation value for the video data is calculated through Equation 1, and Y 'is a color. Value, and U and V are chroma values.

<Equation 1>

When the boundary line of the area divided based on the hue / saturation is confirmed, the advertisement area object detecting unit 115 connects the identified boundary line to the geometric structure of the object area divided based on the hue / saturation. Determine.

The geometric structure may include a geometric shape including N sides and vertices when the advertising area object is an N-angle, or a geometric shape including a center point and a radius when the advertising area object is a cause, or the advertising area object. In the case of an ellipse, it means a geometric shape including a center point and a long radius / short radius.

When the identified boundary line is a straight line cut according to an exemplary embodiment of the present invention, the advertisement area object detecting unit 115 extends the cut line in a corresponding straight line direction to form another second boundary line (or second). And the geometry of the object area based on the crossing position.

According to another exemplary embodiment of the present invention, when the identified boundary line is a cut curve, the advertisement region object detecting unit 115 extends the cut curve while maintaining the curvature of the corresponding curve, and thus another second boundary line. (Or an extension line of the second boundary line), and determine the geometry of the object area based on the crossing or tangent position.

According to an exemplary embodiment of the present invention, when the boundary line is extended to determine a geometry, the advertisement region object detecting unit 115 may determine an area inside the extension line maintaining the geometry as an advertisement region object.

For example, when the geometric structure determined by extending the boundary line is a quadrangle consisting of four sides and four vertices, the advertisement region object detecting unit 115 maintains the four sides and four vertices while maintaining the extension line. The rectangular area consisting of the inner area may be determined as the advertisement area object.

When the advertisement area object corresponding to the geometry condition is determined, the advertisement area object detecting unit 115 performs a function of checking whether the color / saturation value in the geometry constituting the advertisement area object satisfies the palette configuration condition. You can do more.

When the color / saturation value in the geometry satisfies the palette configuration condition according to an embodiment of the present invention, the advertisement area object is included when the color / saturation value in the geometry satisfies the palette configuration condition. In contrast, if the color / saturation value in the geometry does not satisfy the palette configuration condition, the geometry may be excluded from the advertisement area object.

For example, the number of colors in the geometry among the advertisement area objects determined based on the geometry condition is within a preset number, or the average value of the saturation values in the geometry is within the preset reference saturation value, or the geometry Only the geometry in which the deviation of the RGB values between the colors within the predetermined range is maintained as the advertisement area object, and the geometry not otherwise may be excluded from the advertisement area object.

According to another exemplary embodiment of the present invention, when the pallet condition is not provided in the detection condition D / B 150, the advertisement area object detecting means 115 determines that the advertisement area object satisfies the pallet condition. In this case, the advertisement area object may be detected using only geometrical conditions.

When an advertisement region object corresponding to at least one of the geometry structure and the palette construction condition is detected from the video data of the video content, the object structure reading means 120 determines the geometry of the advertisement region object and the preset reference geometry. The structure is compared to determine a geometry deformation value that determines how the geometry of the advertisement area object is deformed based on the reference geometry.

Here, the reference geometry is a regular N-square, the length of the sides of N (N> = 3) and the vertex reference angle is the same, at least one of the angles of the angle of the N-angle, the right angle N-angle, the center point and the radius It may include a geometry of any one of a circle having a symmetrical curvature in the left / right or up / down direction, an ellipse having a central point and a long radius and a short radius, and having a symmetrical curvature in the left / right or up / down direction.

When the geometry of the advertisement area object is an N-square consisting of sides (N> = 3) and vertices of the advertisement area object, the geometry deformation value is the length of the side compared to the length and slope of the N sides constituting the reference geometry. It may include one or more deformation value and the slope deformation value of the side, or may include one or more distance direction value and a distance value of the vertex compared to the N vertices constituting the reference geometry.

Alternatively, when the geometry of the advertisement area object is a circle consisting of a center point and a radius or an ellipse consisting of a center point and a long radius and a short radius, the geometry deformation value includes a symmetry ratio value for left / right or up / down curvature. can do.

For example, when the geometry of the advertisement area object is a trapezoid consisting of four sides and four vertices, the object structure reading means 120 uses the quadrilateral or quadrangle rectangle as the reference geometry. A geometry that determines whether the length of the four sides of the trapezoid is reduced or increased based on the four sides constituting the quadrilateral or the right quadrangle, and which slope is smaller or larger at the right angle slope. The deformation value can be determined.

Alternatively, when the geometric structure of the advertisement area object is a trapezoid consisting of four sides and four vertices, the object structure reading means 120 uses the regular quadrangle or the quadrilateral rectangle as the reference geometric structure. Based on the position of the four vertices constituting the rectangular or rectangular quadrilateral, the geometric deformation value for determining how far the four vertices constituting the trapezoid are separated in which direction may be determined.

Alternatively, when the geometry of the advertisement area object is an egg shape, the object structure reading means 120 uses an ellipse including a center point and a long radius / short radius as the reference geometry to form the left / right or the top of the egg shape. The geometric deformation value may be determined to determine which curvature of the lower / lower curvature is smaller or larger based on the symmetrical left / right or upper / lower curvature of the ellipse.

According to the exemplary embodiment of the present invention, if the video content is obtained by photographing an object in a 3D space, an object included in the video data of the video content is naturally displayed with perspective. Therefore, as the geometry of the advertisement region object detected from the video data of the video content is closer to the singularity based on any singularity inside / outside the video playback region, the smaller the object becomes, the blurry and the farther from the singularity As the size of the object becomes larger, a sharpening perspective will be applied, and the geometry deformation value may include a deformation of the geometry by the perspective.

According to an embodiment of the present invention, when the geometry of the advertisement region object is N-shaped, the perspective value checking means 125 may be configured based on any singularity inside or outside the video reproduction region that plays the video content. The geometric deformation value may be read to determine whether the length of the side of the geometric structure constituting the advertisement area object includes a perspective value that is shorter as it approaches the singularity direction and larger as it moves away from the singularity direction. Here, the perspective value may include a side length ratio value with respect to a length of a side close to the singularity direction and a side of a side opposite to the singularity.

For example, if the geometry of the advertisement area object has a short length of the side close to the singularity direction and a length of a side opposite to the singularity is relatively longer than the singularity direction, the trapezoidal geometry has a perspective value. It can be confirmed to include.

According to another exemplary embodiment of the present invention, when the geometric structure of the advertisement area object is a circle or an ellipse, the perspective value checking means 125 may refer to any singularity inside or outside the video playing area for playing the video content. By reading the geometric deformation value, it is possible to determine whether the curvature of the geometric structure constituting the advertisement region object includes a perspective value that decreases closer to the singularity direction and larger toward the singularity direction. Here, the perspective value may include a curvature ratio value for a curvature of a curve close to the singularity direction and a curvature of a curve in a direction opposite to the singularity.

For example, when the geometry of the advertisement area object has a small curvature of the curve close to the singularity direction and the curvature of the curve opposite the singularity is relatively larger than the singularity direction, the egg-shaped geometry is It can be identified as including a perspective value.

Referring to FIG. 1, the content operation server 100 includes advertisement data checking means 130 for checking advertisement data to be displayed on the advertisement region object.

The advertisement data checking unit 130 may first determine advertisement data to be displayed on the advertisement region object based on a category comparison between the video content and the advertisement data and a keyword comparison.

If there is more than one advertisement data determined based on the category comparison or the keyword comparison, the advertisement data checking unit 130 may determine the geometric structure condition of the advertisement display condition and the advertisement region corresponding to the first determined advertisement data. By comparing the geometric structure conditions of the object, the advertisement data matching the geometry may be determined as advertisement data to be displayed first in the advertisement region object.

For example, if the geometry of the first determined first advertisement data is a rectangle and the geometry of the second advertisement data is an ellipse, and the geometry of the advertisement region object is elliptical, the advertisement data to be displayed first on the advertisement region object May be first determined as the second advertisement data.

Alternatively, the advertisement data checking unit 130 compares the palette configuration condition of the advertisement display condition corresponding to the first determined advertisement data with the palette configuration condition of the advertisement area object to display the advertisement data matching the palette configuration. This may be determined as advertisement data to be displayed first in the region object.

For example, when the palette configuration of the first determined first advertisement data is red and white, and the palette configuration of the second advertisement data is blue and green, and the color in the geometry of the advertisement area object is light blue, the advertisement area The advertisement data to be displayed first on the object may be first determined as first advertisement data having a complementary color relationship with the color in the geometry.

Referring to FIG. 1, the content operation server 100 reads the geometric transformation value and calculates a coordinate conversion equation for displaying advertisement data of a rectangular area on the advertisement area object. And ad content generating means 140 for generating ad content to be displayed on the ad area object by transforming the rectangular area of the ad data according to the coordinate conversion equation, and displaying the ad content on the ad area object. Ad content display means 145 is provided.

The geometric deformation value determined by the object structure reading means 120 includes coordinate values on a two-dimensional coordinate system that deforms the shape of the advertisement area object while maintaining the geometric structure, but by the perspective value checking means 125. The identified perspective value includes a depth value (eg, a coordinate value in the z-axis direction orthogonal to the xy axis of the two-dimensional coordinate system) that converts the two-dimensional coordinate system into the three-dimensional coordinate system. Accordingly, the conversion calculating means 135 converts the reference geometry into a geometry to which the perspective value is applied while maintaining the shape of the geometry corresponding to the geometry deformation using the geometry deformation value and the perspective value. Calculate the coordinate conversion equation. Here, the coordinate conversion equation may be expressed as Equation 2.

<Equation 2>

On the other hand, when the video content is a video shot in a limited space such as a studio, or when the advertising area object is located in the horizontal direction in front of the camera lens, the perspective value may not exist in the geometry of the advertising area object. Even if a perspective value exists, the magnitude of the value may be a small value within an error range.

Alternatively, when a special lens such as a wide-angle lens is attached to the apparatus for capturing the video content, distortion occurs in the video data of the video content, and the geometry of the advertisement region object also causes distortion.

When there is a perspective value, a small value within an error range, or a distortion occurs as described above, the conversion calculating means 135 excludes the perspective value and deforms the geometry. The coordinate conversion equation on the two-dimensional coordinate system can be calculated using the value.

The advertisement content generating unit 140 is a coordinate value before the coordinate conversion of the coordinate value on the two-dimensional coordinate system for the four sides (or vertices) constituting the rectangular area of the advertisement data identified by the advertisement data checking means 130 In addition, the coordinate conversion equation is applied to the coordinate value before the coordinate change to generate the advertisement content having the perspective value applied to the rectangular area of the advertisement data (= smaller as the closer to the special point and larger as the farther point).

When the advertisement data includes an advertisement region and a transparent region, the advertisement content generating unit 140 may set the color / saturation value of the boundary region between the advertisement region and the transparent region to the color / saturation value of the advertisement region and the advertisement. The advertisement content may be generated by determining an intermediate value of the hue / saturation values of the palette configuration corresponding to the area object.

According to an embodiment of the present invention, the process of detecting the advertisement region object from the video data of the video content, calculating the coordinate conversion equation for the advertisement region object and generating the advertisement contents to be displayed on the advertisement region object may be performed. M video data included in the content is repeatedly performed, and the advertisement content is generated in the form of advertisement image content for each video data, or in the form of advertisement video content to be displayed and played on i (i> 1) video data. Can be.
