Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and a method for providing additional information using a line code provided at an edge of a screen,

The present invention relates to a system and method for providing additional information by using a line code provided at an edge of a screen, and more particularly to a system and method for providing additional information by using an edge code Pattern recognition is made clear by configuring the identification code in the form of an image pattern in the form of a line, and the pattern recognition is easy even at a long distance by arranging the line pattern in the "L" type having the direction corresponding to the corner, The present invention provides an additional content information providing system capable of combining a plurality of lines by dividing a line pattern by the presence or absence of a pattern, a length, a thickness, and a type.

Generally, a QR code (Quick Response code) is a matrix-type two-dimensional bar code representing information in a monochrome plaid pattern. In 1994, Toyota's subsidiary, DENSO WAVE, developed a logistics management system. The name is derived from Denso Wave's registered trademark Quick Response. In contrast to the existing vertical bar code, only the numbers could be stored. QR code, however, can store texts so that the amount of information is infinitely increased and connected to the Internet for detailed product information and images And moving images. It is a matrix-like two-dimensional code in which the same number of small square points are arranged side by side and vertically so that it can be recognized in any direction at 360 ° and more information can be recorded. Such a QR code is used for displaying information such as advertisements or signboards.

In recent years, there has been a tendency to display a QR code on a screen in the form of computer graphics (CG) on a TV broadcast program as well as a printed matter, or to expose a QR code using DTV data broadcasting technology.

However, when the above-described QR code is provided to the screen, the QR code provided at the center of the screen interferes with the reference image. The QR code occupies a space with a predetermined volume even if it is disposed at one corner of the screen, and thus the view of the viewer is opposed.

In particular, the QR code itself is small, so even if the distance is short, recognition may fail.

The smart device 140 may be a mobile terminal such as a smart phone, a mobile phone, an iPhone, a notebook computer, or the like, as long as it can have various communication functions such as communication via a network and short-range wireless communication. Here, it is assumed that the smart device 140 is equipped with a scanner or a camera module 142.

The smart device 140 includes a camera module 142 for scanning an identification code on the screen M in accordance with a control signal of a control unit to be described later and an identification code interpretation APP together with a basic program for controlling the overall operation of the smart device A memory module 144, a control module 146 for driving the identification code analysis APP or directly communicating with the content server 120 to convert the identification code 102 into content information, A display module 148 for displaying or telling, and a communication module 150.

Therefore, the additional content information is a combination of letters, numbers, symbols, or pictures that the user can directly recognize. Or voice combination. The additional contents information may include various information related to the artist, the PD, the actor, the props, etc. in the case of the drama.

Here, the identification code analysis APP includes a corner detector P1 for detecting the corner area of the screen M, a pattern image of the identification code 102 in the corner area, and a pattern image in the obtained identification code 102 An image processing unit P4 for generating supplementary content information from the pattern image using the stored code data, a data storage unit P3 for storing the code data corresponding to the pattern image, . Here, the code data is a code for converting the pattern image into the code information 102.

The edge detection unit P1 detects the edge of the screen M and extracts only the pattern image in the detected edge area. If the edge area is inclined as a preliminary operation, , And even when the screen size is different, it is also possible to perform a function of resizing it to the same size environment.

The content server 120 includes a supplementary information production section 122 for generating supplementary content information, a supplementary information library section 124 for storing supplementary content information, and supplementary information transmission section 120 for transmitting the supplementary content information to the broadcasting server 110 (Not shown).

The broadcast server 110 broadcasts the content information and the identification code 102 in association with each other in order to convert the additional content information into the identification code 102. [ To this end, it includes an identification code DB 112, an additional content information DB 114, and an encoding unit 116 for converting the additional content information into an identification code.

 Here, the broadcast server 110 has no restrictions such as an over-the-air broadcast server and an Internet broadcast server. That is, the broadcasting is not limited to the airwave broadcasting, but includes all broadcasting relayed to computers, smart devices, other wireless communication networks, the Internet, and other wired communication networks.

Although the broadcast server 110 and the content server 120 are independently described in the embodiment of the present invention, the present invention is not limited to this, and the additional content information may be generated by one server and simultaneously encoded with the identification code .

As described above, according to the system 100 for providing the additional information using the line code provided at the corner of the screen of the present invention, the smart device 140 equipped with the camera module 142 can identify It is possible to service various supplementary contents information related to broadcasting by using the code analysis APP.

The present invention can directly decode the additional content information through the code data stored in the smart device 140. The additional information library unit 124 performs network communication with the content server 120, Lt; / RTI >

In the present invention, the identification code includes a pattern image. Here, the pattern image can be designed in the form of a line code that can be arranged in the four corner areas of the screen M. [

≪ Basic Embodiment >

Referring to Fig. 5, the line code is designed as a directional "L" character type located at the four corners of the screen M so that the screen M is not disturbed by the pattern image.

Therefore, each corner has a "━" pattern, no, and a "┃" pattern. Each edge can have 2 bits (2 squared) of information. 4 edges can have 8 bits (2 to 8 squared) of information. Thus, one screen (M) having four corners can represent 255 information basically.

If there is an "L" pattern at the four corners, the pattern becomes "11 11 11 11" and has a value of "255" (at this time, Quot; L "pattern is present in only the first corner, it becomes" 11 00 00 00 ", so that it has a value of "2 ".

As such, there is at least a line pattern at each corner of the screen and there is little chance of failing to recognize the pattern because it is sufficient to recognize only the line pattern.

≪ First Expansion Embodiment >

The identification code of the above line pattern can be further extended.

6, there is a line, and in addition to the absence, a line length, a thickness, a color, a type (for example, solid line / dotted line or straight line / ridge line) Can be more.

For example, the first edge is coded by a combination of (a), (b) and (c), the second edge is coded by the combination of a long line (c) and a short line (d) Is coded by a combination of a solid line () and a dotted line (D), and the fourth edge is coded by a combination of (D) and (D). Other combinations of bold lines and thin lines, and combinations of various color lines can be considered. Here, the length and type of the line, in which the line pattern recognition is relatively easy, and the presence or absence of the icon will be described as an example.

For example, in addition to the presence or absence of a line (with or without a line), the length of the line (long and short lines), the type of line (solid and dashed lines) When included, all 32 bits (32 squared of 2 = up to 4,294,967,296) can be distinguished.

≪ Second Expansion Embodiment >

Although not shown in the figure, if the line pattern of the above-described first extended embodiment is extended to two lines again, content information can be obtained up to 32 bits X 32 bits (32 squares of X 2 and 32 squares of 2). If this information is similar to the IPv6 address, it can also be used as an Internet address.

Referring to FIG. 7, as described above, when the range of the identification code is extended to 32 bits, it is possible to design the identification code for additional content classification as follows.

First, an ID is set for each channel, a program ID of each channel is set, and an ID is set for each program in each program.

For example, the above-mentioned channel ID can be allocated to 8 bits, and a maximum of 255 channels can be distinguished. The program ID can be allocated to 16 bits, and a maximum of 65,536 programs can be distinguished. It can be divided into 255 areas.

Hereinafter, a method of providing additional information using a line code provided at the corner of the screen will be described.

First, the encoding process of additional content information will be described.

The identification code is designed as described above. The channel ID, the program ID, and the broadcast time ID. When receiving the additional content information from the content server, the additional content information is encoded into the identification code.

Next, a decoding process of the additional content information will be described.

As an advance preparation process, the identification code analysis APP is driven.

The identification code interpretation APP is registered in the content server 120 and the viewer can install the identification code interpretation APP without difficulty if the viewer identifies the identification code of the screen or a separate QR code or RFID tag by photographing or scanning with the camera section. Alternatively, when the content server 120 links with a known site such as an app store or a te store, a viewer can search for an identification code interpretation APP in an app store or a web space and directly download the APP. When the APP is downloaded for convenience, the associated icon is placed on the desktop so that it can be activated immediately.

When the identification code interpretation APP is activated, the screen M of the broadcast receiver 130 is photographed using the camera module 142 of the smart device 140. In operation S10,

At this time, the edge detector P1 is activated to detect the four corners of the screen M. (S20)

The screen M is aligned (rotational alignment / size alignment) (S30)

Since the four corners of the screen M have respective unique identification code values, the order must be taken into account. Therefore, even if the screen M is taken at an angle, the screen M can be aligned and clockwise oriented with respect to one edge. Also, since the size of the screen M may be different for each broadcast receiver 130, the direction and size of the rotation must be aligned before extracting the identification code 102.

The identification code 102 is extracted (S40)

When the edge of the screen M is detected and the screen M is aligned, the pattern extracting unit 102 extracts the pattern image of the identification code 102 in the edge area using the image extracting unit P2.

The identification code 102 is analyzed (S50) and converted into additional content information (S60)

The image processing unit P4 analyzes the pattern image using the code data of the data storage unit P3 and generates additional content information in the pattern image.

For example, the pattern image may be analyzed to generate additional content information on the smart device 140 itself if the pattern image has basic information. Or if the pattern image has moving image information, additional content information may be provided from the supplementary information library unit 124 of the content server 120. [

As described above, according to the present invention, the line pattern is arranged in the corner area of the screen so that the line pattern is not in conflict with the reference image and the line pattern is arranged in the "L" It can be seen that the technical idea is to provide a supplementary contents information providing system in which each line pattern is divided into a pattern presence / absence, a length, a thickness, a type, and a combination of icons. Many other modifications will be possible to those skilled in the art, within the scope of the basic technical idea of the present invention.
