BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an advertisement display device, and more particularly, to a display device for advertisements or subtitles that enables continuous output of an image such as an advertisement or a text without covering a video screen on a portion of a television screen.

In general, advertising is an information activity invested by companies, individuals, and organizations in order to inform the world of goods, services, ideas, beliefs, policies, etc. to achieve their desired purpose.

Such advertising is carried out through the media, and the advertising media is classified into newspapers, magazines, outdoor installations, transportation (for example, buses), theaters, radios, televisions, and the like.

Among them, TV commercials are targeted to a large number of viewers, so the advertising effect is the best. Good advertisements impress viewers and help them sell products for a long time.

However, in order to advertise through TV, it has to be costly because it requires a request from a public broadcasting station or a cable broadcasting station. Moreover, since the advertisement must be newly produced in order to export the advertisement with new contents, the amount of money invested in the advertisement has been increasing exponentially.

As a result, advertisers are demanding a new way of advertising that enables them to advertise at a low cost with high concentration of viewers on television. The on-screen display (OSD) function of television is used as a niche for advertising. Used advertising is being developed. As one kind of advertisement, a television that displays a specific advertisement logo or text for a predetermined time at the moment of switching between channels is developed and marketed. The advertising effect is achieved by drastically discounting the selling price of commercially available televisions and encouraging them to watch advertisements.

However, the television outputs an advertisement for a predetermined time during the channel and channel switching, at this time, there is a problem covering a part of the video screen of the television.

Because of this, there was a serious problem of not watching TV properly.

In particular, there is a problem that the viewer does not sufficiently recognize the advertisement because the advertising time is short.

Accordingly, the present invention has been proposed to solve the above-mentioned problems according to the prior art, and an object of the present invention is to allow a portion of a television screen to continuously output images such as advertisements or texts without covering the video screen. The present invention provides a display device for an advertisement or a subtitle.

And a video D / A converter 70 for reading a video signal stored in the FIFO video buffer memory 60 and overlaying the graphic data or picture data with the advertisement or subtitle data to convert to a television screen. do.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of a display device for advertisements or subtitles according to the present invention will be described.

1 is a block diagram of a display device of an advertisement or a caption according to the present invention.

As shown in Fig. 1, a television advertisement apparatus according to the present invention comprises: a NAND or NOR type flash memory 10 containing advertisement or subtitle data; A microcontroller 20 having a graphics processor to control the entire system of the advertisement device and to control a NAND or NOR type flash memory 10 containing video overlay generation, advertisement or subtitle data; A cable television tuner (CATV Tuner) 30 for tuning an analog broadcast signal received from an external cable or a TV antenna and outputting the tuned analog broadcast signal; In addition to receiving an analog audio / video signal from an external terminal, an analog broadcast signal output from the cable television tuner 30 is received, and the received analog video signal is converted into a digital video signal. Scaled video signal, sync signal (horizontal-sync, vertical-sync) and other signals (horizontal, vertical-scaler, clock, field) according to the control of horizontal and vertical down / up scaler to change the digital video signal A video A / D converter 40 for outputting a); Receives and stores the synchronization signal output from the video A / D conversion unit 40 and various other signals, and receives the synchronization signal and various remaining signals output from the video D / A conversion unit 70 to be described later. A video buffer memory control logic unit 50 for timing generation of writing or reading data from the FIFO video buffer memory 60 to be described later; A FIFO video buffer memory 60 for receiving and temporarily storing the scaler converted video signal output from the video A / D converter 40 and outputting the stored video signal; And a video D / A converter 70 for reading a video signal stored in the FIFO video buffer memory 60 and overlaying the graphic data or picture data with the advertisement or subtitle data to convert to a television screen. do.

Referring to the operation of the display device of the advertisement or subtitle according to the present invention configured as described above are as follows.

First, the advertisement or subtitle data is stored in the NAND or NOR type flash memory 10 of the display device of the advertisement or subtitle prior to the operation of the present invention.

When storage of advertisement or subtitle data is completed in the NAND or NOR type flash memory 10, the cable TV tuner 30 includes an analog broadcast signal received from an external cable or a TV antenna. Tune and output the tuned analog broadcast signal.

The video A / D converter 40 receives an analog audio / video signal from an external terminal, receives an analog broadcast signal output from the cable television tuner 30, and receives the received analog video signal. Convert to a digital video signal. In addition, the video A / D converter 40 includes a horizontal and vertical down / up scaler for changing a screen size, and the horizontal and vertical down / up scaler is a control signal preset to the microcontroller 20. According to the present invention, the screen size is adjusted accordingly, and the converted digital video signals (video signals, synchronization signals (horizontal-synchronous, vertical-synchronized) and various remaining signals (horizontal, vertical-scaler, clock, field)) are output.

For example, when the video screen is reduced to the Y-axis during the operation of the horizontal and vertical down / up scalers (ie, the process of vertical down-scaling is performed). As shown in FIG. 2, the screen is cut out at equal intervals or corresponding intervals. Thus, blanking (vertical down-scaled portion) to be commercially generated occurs at the bottom of the screen.

The video buffer memory control logic unit 50 receives the synchronization signal output from the video A / D conversion unit 40 and various other signals, and the synchronization signal output from the video D / A conversion unit 70 to be described later. Various remaining signals are received and stored, and the timing of writing or reading data is generated in the FIFO video buffer memory 60 which will be described later.

The FIFO video buffer memory 60 receives and temporarily stores the scaler converted video signal output from the video A / D converter 40 according to a timing of writing or reading data of the video buffer memory control logic unit 50.

The video D / A converter 70 receives the advertisement or subtitle data stored in the NAND or NOR type flash memory 10 according to the control signal of the microcontroller 20, and the scaler stored in the FIFO video buffer memory 60. The converted video signal is read, and the graphic data or picture data is overlaid with the advertisement or subtitle data, converted into a final television screen, and then output to the television. In addition, the video D / A converter 70 feeds a synchronization signal (horizontal-synchronous, vertical-synchronous) and various remaining signals (clock, field) to the video buffer memory control logic unit 50.

Thus, as shown in FIG. 3, the television screen displays an advertisement screen overlaid on a video vertical down-scaled image.

As described above, according to the present invention, since the size of the television screen can be changed, the advertisement or subtitle can be displayed at any time without covering the background screen.

As a result, the present invention can be advertised to viewers for a long time to produce and send a new advertisement at a low cost, and also helps to sell the product.
