Description

Method for searching broadcasting program

The present invention relates to a program control method of a video device for receiving a broadcast for data broadcasting, and more particularly, to a broadcast program search method for searching for information of a broadcast program only with specific information.

A data broadcasting system that is implemented in Korea is called a K-broadcasting system, and a K-broadcasting program broadcasts data encoded by a broadcasting station so that a user can easily use information about a broadcast program according to a scheduled recording or a broadcast time. Broadcast information having data loaded on and transmitted to the network.

In general, each broadcasting station transmits only broadcast program information transmitted from its own broadcasting station on the broadcasting signal of the corresponding channel.

Accordingly, if the K key is immediately turned on in order to use the broadcast program information while the broadcast signal is being viewed by the broadcast signal receiving side, only the bar K program of the received channel is displayed on the screen as shown in FIG.

In the conventional broadcast program search method, when the user does not know the broadcast date, time, and broadcast channel of the broadcast program that the user wants to select, the time is increased when the broadcast program is searched because the broadcast program must be checked by using the cursor keys. Not only a lot of use but also had a cumbersome operational problem.

SUMMARY OF THE INVENTION The present invention has been made in an effort to provide a broadcast program search method for searching for broadcast program information related to a key word by using a specific key word in order to solve the above problem.

1 is a flowchart of a broadcast program searching method according to the present invention.

2 is a block diagram of a video recording / reproducing apparatus to which the present invention of FIG. 1 is applied.

3 illustrates a display state of a screen in each configuration process of FIG. 1.

Figure 4 shows a bar program display screen according to the prior art.

In accordance with another aspect of the present invention, a broadcast program search method includes: a command determination process of determining whether a broadcast program search command is input, and inputting a keyword of a broadcast program to be searched when the broadcast program search command is input; A key word input process, a search process for searching for a broadcast program having the input key word in a memory, and a program display process for displaying the searched broadcast program on a screen are included.

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

1 is a flowchart of a method for searching a broadcast program according to the present invention, in which a data storage process 110 for storing received shipment program data, a first determination process 120 for determining whether a program search command is input, and a keyword are shown in FIG. A dialog box display process 130 for displaying a margin that can be input, a keyword input process 140 for inputting a keyword, a second determination process 150 for determining whether a predetermined time has elapsed, and an input keyword A program search process 160 for searching and a program display process 170 for displaying the searched program are provided.

2 is a block diagram of an apparatus to which the present invention is applied, a tuner 210 for outputting a broadcast signal tuned to a frequency of a broadcast channel selected from broadcast signals of respective broadcast stations, and a demodulator 220 for demodulating an input video signal. ), A data slicer 230 for extracting only broadcast program data among the demodulated video signals, a decoder 240 for decoding the extracted broadcast program data, a memory 250 for storing the decoded broadcast program data, After searching for data, the control unit 260 assigns an address and controls to read the data, a character generator 270 for generating a character corresponding to the read data, the demodulated video signal and the read broadcast program information. And a mixer unit 280 for synthesizing the character signals.

The configuration of FIG. 2 is similar to that of a conventional KBPS system receiving apparatus, but the operation of the controller to which the method according to the present invention is applied has a configuration different from that of the conventional technique as described below.

The present invention will be described in detail with reference to FIG. 2 with reference to FIG. 1.

The data storing process 110 is a process of storing data regarding broadcast program information, which is included in a demodulated image, in the memory 250.

The first determination process 120 is a process of determining whether a program search command for searching for a broadcast program is input. That is, the controller 260 determines whether a user inputs a predetermined program search key (not shown) installed separately from the outside of the video device.

The dialog box display process 130 is a process of preparing and displaying a place where a keyword can be input on the screen when a program search command is input. That is, if a program search key is input while watching a screen as shown in FIG. 3A, a process of displaying a dialog box for inputting a key word at the bottom of the screen as shown in FIG.

The keyword input process 140 is a process of inputting a keyword of a program to be searched by a user. In this case, when the user knows the entire program name to be searched, the entire program name is input as shown in (g) of FIG. When a keyword is entered, it displays the entered word in a dialog box on the screen.

The second determination process 150 is a process of determining whether another key word is not input until a predetermined time elapses after the key word is input.

The program search process 160 may store a broadcast program including the input key word when the key word is not input for a predetermined time after the second determination result key word is input or when a predetermined execution command is input. ) To search for and read. While the program search is being executed, a message indicating that the screen is being searched on the screen is displayed in the dialog box as shown in FIG.

The program display process 170 is a process of displaying the found broadcast program on the screen. That is, the program information including the key word read out from the memory 250 is displayed on the screen by the image information generated through the character generator 270 in the configuration as shown in FIG. The item for displaying the searched program includes at least the broadcast program name, broadcast station name, date, and time.

If the number of found broadcast programs is less than or equal to a predetermined setting value, as shown in FIG.

However, if a program including a keyword is not stored in the memory, a message indicating that no program is found is displayed on the screen as shown in FIG.

Through the above process, it is possible to easily search for the information of the program to find in the device receiving the data broadcast signal.

As described above, according to the present invention, by searching for a broadcast program by a keyword, there is an effect that the broadcast program can be easily and quickly searched even when the broadcast program information is not accurately known.
