Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the advertisement logo output apparatus of the television of the present invention, the advertisement logo stored in the advertisement logo output apparatus of the present invention is displayed on the screen of the television when the television is turned on normally, When the input is detected, the advertisement text displayed by the advertisement logo output device or the output of the advertisement logo is output and the transmitted advertisement is output, thereby increasing the advertisement effect and preventing the overlap of the advertisement. Therefore, when a commercial is entered that does not include ID and data, the advertisement logo and advertisement text are output.

The description of the present invention first describes a process of inserting an ID and data into a commercial transmitted from a broadcasting station, and describes the configuration and operation of an advertising logo output apparatus installed in a television to output advertisement characters or logos. The advantages of packaging an advertising logo output device are described.

The advertisement characters or logos are image data for advertisements having various colors and complicated shapes at predetermined positions on a television screen, and are continuously and sequentially displayed when broadcasting general broadcasts (dramas, shows, entertainment programs, news, etc.) rather than commercials. Display. An example of display of an advertising logo or text is shown in FIG. 6, which will be described later.

In addition, by inserting ID and data into the commercial, the advertisement logo display device of the present invention not only detects the transmission of the commercial, but also collects various viewing-related data to inform advertisers about the viewer's rating, advertising effect, etc. Can be provided.

1 is a block diagram of a signal insertion apparatus for inserting ID and data into an original video signal for commercial use. The ID may be, for example, an identifier for identifying the commercial. This is an identification symbol for recognizing that the broadcast is an advertisement when the corresponding broadcast is input to the advertisement logo output device and stopping the advertisement logo currently output by the advertisement logo output device. In addition, the data may be content about "broadcasting station", "advertiser", "advertisement content" and the like where the commercial is currently broadcasted. Of course, the ID and data can be set to include other contents. In addition, in the present invention, by inserting a specific ID and data in the portion displayed on the screen (after the scan line 21) to prevent overlapping with the commercial broadcast from the conventional broadcasting station or interfere with the broadcast, friction with the advertising company Can be avoided.

As shown in the drawing, the signal insertion device receives a composite video signal, and converts the signal into a color signal (R, G, B), a luminance signal, a vertical synchronization signal, and a horizontal synchronization signal, respectively, and outputs a signal conversion / separator ( 101), a microcontroller 103 having fonts and graphic data therein and outputting IDs and data at predetermined positions in accordance with the timing of the horizontal and vertical synchronization signals output from the signal converter / separator 101; A frame counter 104 for counting the number of frames with reference to the signal output from the microcontroller 103, and a counter data display 105 for displaying the value obtained by counting the count data from the frame counter 104; And a switch 106 for ID and data input for distinguishing between the normal screen and the OSD screen display control screen and for distinguishing each advertisement, and the switch 106 Data display 107 for displaying the input data value and a mixer 102 for synthesizing the color signals R, G, and B output from the microcontroller 103 and the signal converter / separator 101. And a signal converter 108 for converting the signal output from the mixer 102 into a composite video signal including ID and data.

A commercial video tape of a television is produced by an advertising company, and the recorded original is reproduced by a video editor 109 having a playback function to output a composite video signal (composite video signal). The composite video signal is output at the video line out (not shown) according to the playback command. The output state is shown in Fig. 4, and the even field is omitted because it overlaps with the odd field and only the odd field is displayed.

The composite video signal is played in the order as shown in FIG. 4, and line numbers 1 to 20 of the composite video signal are not displayed on the television screen, and this area is a teletext or closed caption serviced by a broadcasting station. It is reserved for broadcast. Therefore, this area is not used. In the present invention, ID and data are inserted using an area displayed on the screen of a television.

In this case, ID and data cannot be inserted directly into the composite video signal. Therefore, the composite video signal is first divided into a red signal, a green signal, a blue signal, a vertical synchronization signal, and a horizontal synchronization signal. The signal is sent to the microcontroller that controls the horizontal sync signal to be output in the form of OSD automatically according to the timing.

The microcontroller 103 inputs an ID of 1 byte (8 bits) into the OSD bitmap data memory area (display character RAM, display ROM), and coordinate area (horizontal position register / counter, vertical position register / Input data into the counter, counter write address, and address buffer selector), and specify the desired color in the control register. 4 and 5, ID, data, and color information set as described above are displayed. This indicates that the screen position is line number 21, and the color is set to a signal of green dots (1 bit).

The vertical sync and horizontal sync signals are used to completely match the disassembled scan of the camera and the assembled scan of the receiver to reproduce the same screen as the transmitter in the receiving tube on the receiving side. It is necessary to coincide with the starting point (phase), and the transmitting side adds vertical and horizontal synchronous signals for matching among the color television signals.

Reference numeral 104 denotes a frame counter, in which a frame is a completed image which is sent to a scanning line. The frame is counted according to a signal from the microcontroller 103, and information about the beginning and end of the advertisement is sent to the editor and the operator. It helps to input data by informing.

In addition, the counter data display 105 visually displays the frame value counted by the frame counter 104 on an LCD monitor or other display.

In addition, the keyswitch 106 is to distinguish between the normal screen and the OSD screen display control screen, and to distinguish each advertisement.

The data display 107 is also for displaying the value input through the key switch 106 on an LCD monitor or other display.

The signal designated as described above is input to the signal converter 108 after being synthesized again in the mixer 102. The signal converter 108 converts the input signal into a composite video signal and records it through the VCR. In this way, a modified version containing ID, data, and color information is produced from one commercial source. When the modified version of the advertisement is received on the television with the advertisement logo output apparatus of the present invention, the output of the advertisement text or the advertisement logo output from the advertisement logo output apparatus is stopped and the advertisement of the modified version is output.

FIG. 2A is a block diagram of the advertisement logo output apparatus according to the present invention for receiving the modified advertisement as described above and turning on / off the advertisement text or the advertisement logo. As shown in FIG. The microcontroller 209, the interface unit 211, and the advertisement image data storage unit 210 are configured.

Outputs the advertising logo stored in the storage unit 210, by referring to the extracted ID and data on / off control of the advertising text or the advertising logo, and receiving the ID and data included in each commercial broadcast number of views The interface unit 211 serves as an electrical connection between the OSD of the television and the OSD of the advertisement logo output device. The interface unit 211 includes an R, G, and B interface and a blanking interface, and stores the advertisement image data. The unit 210 stores data about advertisement characters or advertisement logos displayed on a portion of a screen of a television as a memory chip. The advertisement image data storage unit 210 may be configured using a large-scale memory chip that can write data from the outside.

If necessary, by configuring the advertisement image data storage unit 210 as a flash type memory, the micro controller 209 receives the updated advertisement data from an external device (computer or other terminal device) using the serial communication port. The advertisement image data storage unit 210 may be stored. This is very useful when configuring the advertisement logo output apparatus of the present invention in the form of an OSD board package.

Referring to FIG. 2A, the video decoder / scaler 200 receives an A / D converter 201 that receives a composite video signal and converts it into a digital signal, and outputs a signal output from the A / D converter 201.

Referring to the operating state of the components as follows.

When the modified composite video signal is input, the A / D converter 201 modulates it into a digital signal and outputs it. The output digital signal is separated into the signal and the color difference signal by the signal separator 203 in accordance with the timing of the synchronization signal. The separated signal is processed again by the vertical and horizontal counters 206 and 207 into vertical and horizontal digital signals, and color information is converted by the color area information converter 208 and input to the microcontroller 209. As described above, the microprocessor 209 extracts ID and data from the input signals and uses them for control.

Fig. 2B is a block diagram showing the coupling state between the interface unit 211 and the television on-screen display unit (OSD).

As shown in the figure, the OSD inside the conventional television is configured with a buffer circuit TR at the end, and the load resistance RL of the buffer semiconductor element is externally attached and connected so that the resistance is dependent on the required impedance and power amount at the rear end. It is configured to select and use the value. However, in the present invention, the load resistance is connected to the interface unit 211 and moved to the inside of the package (described in detail with reference to FIG. 3) to be installed for on / off control of a television screen. In other words, when the TV screen is not output (blanking signal) in the absence of the load resistance, when the package is inserted, the load resistor RL is combined and the screen is normally output. When the package is extracted, the load resistor RL ) Is not coupled to the television, so no screen is output, so viewing is not possible.

This can turn on / off the output of the television by detachably fixing it to the television. Referring to FIG. 3, the video decoder / scaler 200, the microcontroller 209, the advertisement image data storage unit 210, the power supply unit 213, the interface unit 211, and the EEP-ROM 212 are provided. It can be seen that consists of. Since the video decoder / scaler 200, the microcontroller 209, the advertisement image data storage 210, and the interface 211 are the same in FIG. 2, detailed description thereof will be omitted. The power supply unit 213 is configured to be connected to the power source of the television and to receive power therefrom. Fig. 6 is a front view of the television, in which a groove in which a package in a pack form is inserted and extracted is formed. The electrical coupling state in which the package is inserted is connected as shown in FIG. 3.

On the other hand, the interface unit 211 is connected to the blanking signal and the R, G, B of the television OSD, the composite video signal is connected to the video decoder / scaler 200, the vertical, horizontal synchronization signal of the television OSD is a microcontroller ( 209). In addition, the microcontroller 209 is configured with transmission and reception terminals (RXD, TXD) to be used for data transmission and reception with the outside.

The memory unit 212 using the EEP-ROM is a memory in which data is stored by the microcontroller 209. That is, data stored in the EEP-ROM 212, which is a nonvolatile memory device, may be read by the microcontroller 209, and data information may be exchanged with an external device (such as a personal computer or other terminal device) through an external serial communication port. This reads the ID and data included in the modified composite video signal described above with reference to FIG. 2 to store the viewer's number of views, and may be used as judgment data for an audience rating survey or advertisement effect comparison for each advertisement. Of course, it is obvious that other statistical results can be extracted using the counter count.

In the case of applying the advertising package of Figure 3 will be described with reference to Figure 7 the operating state of the advertising logo output apparatus of the present invention. Here, except for inserting and extracting the package, the operation of the advertisement logo output apparatus is the same as that of the state installed inside the television, and thus the description thereof is omitted.

With the television off, power is turned on and the package is inserted into the television. When the package is inserted, TV broadcasting is normally output without a screen output. The user may select a channel and watch a broadcast (news, show, drama, entertainment program, etc.) that he / she wants. At this time, the composite video signal received by the television is received by the advertisement logo output apparatus of the present invention, and it is determined whether the broadcast includes ID and data. If the ID and data are not included, it is not a commercial, so the advertisement logo output device outputs the included advertisement text or advertisement logo to perform advertisement. The package and advertising form are shown in FIG.

If a commercial is input and the ID and data are included in the commercial, the advertisement logo output device stops the currently output advertisement and outputs the commercial on the TV screen so that the normal commercial is output. If the commercial is terminated, the ID and data are not detected again, and the advertisement text or the advertisement logo is output to resume the advertisement.

When the advertisement logo output apparatus of the present invention is manufactured in a package form, there is an advantage that the advertisement contents stored in the advertisement image data storage unit can be easily updated by using an external serial communication port. In addition, there is an advantage that the viewing-related data stored in the EEP-ROM 212 can be easily extracted and used.

In the above description, the ID and the data are inserted into the commercial, but it is apparent that the ID and the data can be inserted into the general broadcast program and used for the survey of the broadcasting rating.

According to the present invention as described above, since the advertising logo is always displayed on a part of the screen when the TV is turned on, the advertising recognition effect is high, and the contents of the advertising logo can be easily replaced, so that various advertisements are frequently provided and transmitted from broadcasting stations. The advertising text and / or the advertising logo may be output without interrupting the commercial broadcast, and collecting viewer-related data on the advertisement transmitted from the broadcasting station may determine the viewer rating and the advertisement effect. In addition, by inserting a specific ID and data in the composite video signal for advertising output from the broadcasting station to provide a signal insertion device that can prevent the overlapping of the advertisement by recognizing the specific commercial in the TV commercial logo output device.
