Hereinafter, referring to the accompanying drawings, a TV advertisement system using a public hearing cable broadcasting network of the present invention will be described in detail.

The present invention is a system for advertising to viewers using a conventional public wired and wired broadcasting network.

First, a configuration of a conventional public wired / wireless broadcasting network will be briefly described with reference to FIG. 1. The public wired and wired broadcasting network transmits a transmission system 10 for transmitting a plurality of broadcast sources through a transmission facility 106 and a video signal (including audio signals) transmitted from the transmission system 10. It consists of a transmission system 20 including an amplifier and a subscriber system 30 for displaying a signal transmitted through the transmission system 20 on a television using a splitter, a terminal device 302, or the like. do.

The broadcasting source in the public wired and wired broadcasting network is produced and transmitted by the studio 104, which is equipped with its own, or the satellite transmitting / receiving unit 101, the VHF / UHF receiving unit 102, and the PP optical communication unit 103. And receives an external broadcast source from the communication unit 105 using the RS232C port and transmits it through the transmission facility 106.

The transmitted video signal is amplified by a relay amplifier which is a transmission facility 201 through a cable (not shown) constituting the transmission system 20 and transmitted to the subscriber system 30.

The subscriber system 30 distributes the video signal transmitted through the cable by using the distributor 301, and the distributed signal is processed by the terminal unit 302 (HTU: Home Terminal Unit) and then the television 303. It is output through the viewer can watch the television. The terminal device 302 will be described later.

2A shows a schematic diagram of a bidirectional cable system, and FIG. 2B shows a schematic diagram of a data communication system.

Broadcast programs provided from the program provider (PP) are transmitted to the integrated cable broadcasting station (SO) through the line provided by the network provider (Network Provider). Such program providers may be broadcasters such as domestic OCN, YTN, foreign NHK, BBC, etc., and comprehensive cable broadcasting stations (SO) may be, for example, domestic Gangnam cable TV and East Seoul cable TV. The SOs provide broadcast programs to the subscriber's television. Each SO is assigned a unique channel. The cable broadcasting station S0 provides the television broadcast to the subscriber SUB through the transmission network also provided by the transmission network equipment NP.

2B is a schematic structural diagram of a data communication system for transmitting and receiving program data. As shown, data is received at a terminal device of a terminal subscriber through a modem, and a file including program content is converted from a comprehensive cable broadcasting station S0 and transmitted to a terminal device of a terminal subscriber through an aggregation modem. This configuration is equally applicable to bidirectional cable TVs.

In the above configuration, the SOs have their own studio 104, as shown in FIG. 1, so that they can broadcast their own commercials, but the program providers have no means to produce or broadcast the advertisements. Even though the SOs are capable of outputting commercials on their own channels, it is difficult to advertise on other channels, and there is a problem of paying high advertising fees even when broadcasting the commercials. The structure of the television advertising system of the present invention for solving this problem is shown in FIG.

By means of the apparatus of the present invention, program providers or integrated cable broadcasting stations can be the respective commercial subjects. In other words, the program provider recruits advertisers, generates advertisements as text or subtitle data, and then transmits them to the comprehensive cable broadcasting station (SO) through the transmission network to broadcast the advertisements through the subscriber television 303. In addition, a plurality of SOs may also recruit advertisers and generate advertisement content as text or subtitle data, and then request advertisements from SOCs that are in charge of areas where the advertisements are desired to be broadcast. At this time, the advertisement content may be transmitted from a remote location using a data communication device 108 such as ADSL or LAN. Ad content can be used without any restriction by unifying character or subtitle data format. Such text for advertisement and caption broadcasting data can be generated by the data generator 107 described below.

Comparing FIG. 3 with FIG. 1, it can be seen that new components are added to the transmission system 10 and the subscriber system 30 constituting the conventional public wired and wired broadcasting network.

In other words, the transmission system 10 includes a data generator 107 for text and subtitle broadcasting, and a data communication device 108 for transmitting data between the data generator 107 and an external device. The data generator 107 for text and subtitle broadcasting can be configured using a device such as a PC, for example. Of course, the PC must have a program for writing text or closed caption data. Such a program may include a function to give a special effect to text or subtitle data.

In addition, the data communication device 108 may be connected to a communication device of a program provider (PP) or another comprehensive cable broadcasting station (SO) that wants to broadcast commercials, so that the text communication device 108 may be produced by a program provider (PP) or another comprehensive cable broadcasting station (SO). Advertisements can be received by receiving caption data. The data communication device 108 receives text or subtitle data using TCP / IP, which is an internet data transmission / reception protocol. The received text or caption data has a data format that is essentially the same as the text or caption data generated by the data generator 107. Therefore, it is possible to send to the subscriber system 30 for direct advertising without additional conversion work. In order to receive such data, the data generating device 107 includes a communication program for performing the communication function of the data communication device 108. Such a communication program may use a commonly used WEB-based browser or FTP protocol.

Data generated by the data generator 107 is allocated exclusively by the integrated cable broadcasting station SO, and is transmitted through a channel which is not currently used for broadcasting. Therefore, it does not affect other broadcasting channels. However, in the television 303 of the subscriber system 30, the advertisement is included and outputted even when watching the broadcast of another channel.

In addition, the terminal apparatus 301 of the subscriber system 30, which is a conventionally used conversion apparatus, further includes a sub circuit 304 (SUB circuit) for inserting and outputting advertisement content into a video image screen. The subcircuit 304 is described in detail with reference to FIG. 5.

The sub-circuit 304 receives the character or subtitle data transmitted from the data generator 107 of the transmission system 10, and tunes and converts the received data by the terminal apparatus 302 to output the television video signal. It is included in and output to the television 303. At this time, the position of the character or subtitle data is also set. Character or subtitle data is normally displayed at the bottom of the screen, and the screen processing for such positioning is performed by the sub circuit 304.

4 is a block diagram showing a schematic configuration of a terminal apparatus 302 used in the related art. The cable input signal is removed by the high frequency component while passing through the intermediate frequency detector 502 after the specific broadcast station is tuned by the tuner 501. This signal contains both a video signal and an audio signal. The video signal is output as a video signal in a normal state after the scramble is removed through the decryption decoding unit 505.

On the other hand, the audio signal is output by the voice multiple processing unit 503, the voice output (R, L) and also modulated by the modulator 504 and then output as an RF signal. The control operation of the terminal device 302 is performed by the microprocessor 507, and the control program is embedded in the ROM 508. In addition, the remote control unit 509 is connected to the microprocessor 507 to perform a command when a remote control signal is input. The operation status is visually displayed through the front display 510 at the time of performing each function.

5, the following circuit is further added as the subcircuit 304 to the terminal apparatus 302 having the above-described configuration.

The sub-circuit 304 includes a tuner 514 having a fixed channel for tuning a specific frequency band signal among the signals transmitted through the transmission system 20, and a character included in the signal output from the tuner 514. A decoder and scaler 513 for separating video and caption data, notifying a data input state, and processing a video signal to secure space on a television screen for displaying advertisement text or subtitles, and the decoder and scaler 513. Graphic processing and control unit 512 to be notified of the input of subtitle data from the user, to rearrange and store the data according to the received command, to control the text display state, and to convert the character or subtitle data into a graphic image for display on a television screen. And the advertisement data converted by the graphic processing and control unit 512, and the graphic processing and control unit 5 The real time clock for notifying the graphic processing and the control unit 512 by dividing the memory unit 511 in which the control program of FIG. 12) is stored and the reference time for displaying an advertisement screen on a television screen by monthly / day of the week / hours. The timer unit 515 further includes an advertisement or subtitle data to be selectively displayed in real time or at a desired time on a predetermined position of the television screen.

The operational state of the subcircuit 304 having the above configuration will be described in time series as follows.

First, it is assumed that the viewer is watching a specific broadcast through the television 303. This is performed using the conventional terminal device 302 shown in Fig. 4, so that an image is normally output to the television 303.

In this state, when the character or subtitle data is transmitted from the data generation device 107 of the transmission system 10 through the dedicated channel of the comprehensive cable broadcasting station SO, the terminal device 302 of the subscriber system 30 is embedded. The tuner 514 receives text or caption data. The received character or subtitle data is decoded by the decoder and the built-in decoder of the scaler 513. After decoding, input of character or subtitle data is input to the graphic processing and control unit 512. The graphic processing and control unit 512 outputs a control command for including the character or subtitle data on the screen output through the television 303.

According to the control command, the video signal output from the decryption decoding unit 505 is input to the decoder and the scaler 513, where space is secured so that text or subtitle data can be synthesized into the video signal. In other words, the scaler of the decoder and scaler 513 processes the video signal to reduce and reposition the lower part of the screen over a predetermined interval so as not to obscure the screen of the cable, and to form a text including advertisement contents in an empty space or Set the position for displaying caption data.

The video signal set as described above is combined with text or subtitle data by the graphic processing and control unit 512 and output as a video signal. On the other hand, the text or caption data is stored in advance by graphic processing. The storage of the processed data is stored in the flash memory unit 511.

The flash memory unit 511 stores processed character or subtitle data, graphic processed video signal data, and / or a control program.

In the above description, the text or caption data transmitted to the video signal is synthesized and output in real time. However, the advertisement content according to the present invention may be displayed separately by a specific time, for example, by month / day / time. All of the display time data is included in the transmitted character or subtitle data, and the time display control data is also stored after reading. The real time clock / timer 515 stores the time display control data read as described above, and outputs a control signal to the graphic processing and control unit 512 to output the advertisement screen at the corresponding time. When the advertisement screen output control signal is input, the graphic processing and control unit 512 synthesizes the text or caption data stored in the flash memory unit 511 with the video signal and outputs the RF signal.

Since the video signal processed by the graphic processing and control unit 512 is a signal without scramble, the video signal is output as a video (video) signal as in the prior art, and is also output as an RF signal by the modulator 504. Embodiments of the screen output as described above are shown in FIG. 6. As shown, when comparing the before and after state of the advertisement screen, it can be seen that a character or a caption indicating a specific advertisement content is further displayed at the bottom of the screen.

Although the above description of the present invention has been described in the case of being applied to a public hearing cable network, it is apparent that the present invention can be equally applied to a satellite broadcasting network or a two-way cable TV network using a set-top box. In other words, the set-top box or the converter may further include means for reading text or caption data and inserting and displaying them on the screen of a television as in the present invention, thereby effectively performing an advertisement.

According to the present invention as described above, it is possible to easily change the advertising content that is changed from time to time, and also the advertising content can be immediately output or output in a desired time zone in real time to increase the advertising effect, and also one cable channel With the advantage that it is possible to perform an advertisement using text or subtitle data for the entire channel.

In addition, since it is possible to receive advertising text or subtitle data using TCP / IP from program providers or other comprehensive cable broadcasting stations (SO), it is possible to advertise regardless of time and place.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the invention, and such variations or modifications will belong to the appended claims. .
