Broadcast information printout of TV

The present invention relates to a broadcast information printout apparatus for a television, and more particularly, by receiving transmission data including broadcast information related to a broadcast program currently reproduced from transmission data superimposed on a television broadcast signal on a television. The present invention relates to a broadcast information printout apparatus of a television, which enables to print out the received broadcast information.

Currently, in a general television, a predetermined broadcasting channel is selected from among a plurality of broadcasting channels transmitted from a plurality of television broadcasting stations, so that it can be reproduced through a CRT and a speaker through video / audio processing. Receiving and playing broadcast programs having various broadcast contents assigned to time zones, various information can be acquired.

In addition, such a television receives a CRT picture in the form of a character or an image by receiving digital decoding data, i.e., teletext data, superimposed between predetermined syringes within a vertical blanking period of a television broadcast signal transmitted through each broadcasting channel band. A teletext information reception function that allows reproduction on an image is adopted.

Meanwhile, according to the teletext information that can be received through the teletext information reception function, for example, news, sports, business, weather forecast, stocks, shopping, science, travel, etc., when the broadcast RF signal is transmitted according to each allocated broadcast channel. After converting and editing various service information such as information into the form of a character or figure, and converting the service information edited into the form of a character or figure into the form of a digital signal, 4H during the 10H to 21H period in the vertical blanking period of the broadcast signal. The multiplex transmission is superimposed within the period, so that it can be provided as additional information in addition to the information according to the main broadcast program of television broadcasting.

In addition, in recent televisions, while watching a predetermined broadcast program, a broadcast screen or the like that temporarily matches a viewer's taste is temporarily selected and converted into print information, thereby printing the paper in color through a color printer connected to the television. A screen print function is provided to enable a printout to the screen. In this screen print function, a predetermined still image captured by a viewer's operation and stored in a memory means is converted into a printable data format and transmitted to a color printer. By doing so, it is possible to print out the desired screen.

By the way, in such a television, the printing output for the print paper is made possible by capturing the capture of the image of the broadcasting program for the predetermined television broadcast which is currently reproduced. In order to find additional product information, such as product specifications and product prices, the viewer has to obtain a separate product catalog to find out the information. When watching a predetermined television program such as a movie or a movie, even if you want to know the plot or theme of the program in advance, it is inconvenient because it can be understood only through other media such as a newspaper or a magazine.

Accordingly, in order to easily check additional information on a program generated when watching a predetermined broadcast program, a print output function for the additional information is required.

Next, the operation of the present invention made as described above will be described in detail with reference to the accompanying drawings.

First, when a predetermined broadcast channel is tuned through the tuner 4, the intermediate frequency is converted, and then the intermediate frequency amplification process is performed through the image IF unit 6, the image detector 8 transmits the corresponding intermediate channel amplified channel. The composite video signal is separated from the television broadcast signal through a detection operation, and the image amplifier 10 amplifies the detected composite video signal in multiple stages and adjusts the luminance of the luminance signal separated from the composite video signal. Contrast adjustment is performed, while the color signal processing unit 12 detects a burst signal from the signal amplified composite video signal, restores a color subcarrier signal based on the detected burst signal, and performs color demodulation processing. Is generated, the RGB color signal and the luminance signal are synthesized and amplified by the image output unit 14, and an image according to a predetermined broadcast program is displayed on the CRT screen. To be reproduced.

At this time, the sync separator 16 separates the sync signal from the composite video signal from the video amplifier 10, and the data slicer 18 includes a transmission included during the vertical blanking period by the separated sync signal. While the data is extracted through the data slice operation, the data type discriminating unit 34 of the transmission data processing unit 20 provides information on additional broadcast information related to a broadcast program that is reproduced through the current CRT screen from the extracted transmission data. As a result of determining the data type, a discrimination signal is generated.

Then, the data decoder 40 performs a decoding operation by the control program from the control memory 36 operated by the control of the main controller 30 to characterize the broadcast information of the transmission data in which the data type is determined. Character data from (38) are converted to display character data and output.

On the other hand, the main controller 30 recognizes the discrimination signal from the data type discriminating unit 34 and prints out a print output for the additional broadcast information on the broadcast program currently reproduced by the key operation of the function setting unit 28. When there is a desired function setting operation, the control memory 36 is controlled to control the decoding operation of the data decoder 40, and the additional broadcasting is performed based on the print format information data extracted from the transmission data. The control operation is performed such that the display text data for the information has the print format, and the print controller 32 prints the print format information data in the lookup table 46 of the print signal processor 22 through control communication with the main controller 30. Generate data parameters according to the print format according to the

Accordingly, the printer format conversion processing unit 48 of the print signal processing unit 22 converts the format of the display text data according to the additional broadcasting information received through the input buffer 44 from the lookup table 46. The conversion process is performed based on the data parameter of the output buffer 50, and is output through the output buffer 50. The printer output driver 24 is driven by the control of the printer controller 32 to print the format from the print signal processor 22. The print data according to the determined and applied display text data is driven to be printed out on a predetermined print paper through the printer output unit 26.

Therefore, when the broadcast program associated with the additional broadcast information printed through the printer output unit 26 is CF broadcast, for example, as shown in FIG. 4A, information such as product specification and product price for the corresponding product is displayed. If the broadcast program related to the additional broadcast information is, for example, a drummer or a movie program, information such as a plot of the drummer or the movie is printed out as shown in FIG. 4B.

According to the present invention made as described above, additional broadcast information related to a predetermined broadcast program to be reproduced on a television is received through transmission data which is superimposed in the vertical blocking period of the television broadcast signal and transmitted on a predetermined print paper. As the print output is enabled, additional information that cannot be displayed on the screen with respect to the broadcast program currently reproduced on the screen can be quickly and easily printed out and confirmed.
