The present invention relates to a channel setting method of a television. More particularly, the program information (PSIP) broadcasted in another channel is searched through a search word while watching one broadcast program, and the dynamic channel is selected from the found channels. The present invention relates to a channel setting method of a television that allows a user to set a preferred channel according to contents of his / her favorite broadcasting program only while watching a television by setting a map.

Currently, TV broadcasting is receiving various services such as general terrestrial broadcasting, cable broadcasting, and satellite broadcasting in response to the diverse service demands of viewers who are beginning to become familiar with computers and the Internet in the face of the transformation of digitalization. do. Therefore, the viewers are watching broadcasts of current events, sports, life information, education, and entertainment programs.

Therefore, by detecting the synchronization signal of the composite video signal received before using the television and automatically retrieving and storing the receivable channel information, when the channel up / down key of the remote controller is pressed, the channel without the broadcast signal is displayed in the stored order. Only the broadcasting channels stored in the channel memory are displayed on the OSD screen, and the channels are tuned and displayed for viewing the channels.

However, when there are many auto-discovered channels, there is a problem in that, in the case of a channel that is frequently viewed by the user, the broadcast channel may be memorized by directly inputting the channel or pressing the channel up / down key to sequentially search for the auto-discovered channel.

Accordingly, in order to solve such a problem, in Korean Patent Application Laid-Open No. 1999-0032573 (published May 15, 1996), which is filed with the present application, in the "preferred channel designation method of television," Disclosed is a method of separately storing only a preferred broadcast channel so that only the designated preferred channel can be searched through the preferred channel up / down key so that the broadcast of the preferred channel can be viewed.

1 is a block diagram illustrating a television to which a conventional channel preference method is applied.

As shown here, an antenna 1 for receiving broadcast signals transmitted from a plurality of broadcast stations, a tuner unit 2 for tuning a broadcast channel to be watched among a plurality of broadcast signals input from the antenna 1, IF amplification section 3 for amplifying the intermediate frequency of the composite video signal input and tuned from the tuner section 2, and P for separating the video signal and audio signal from the composite video signal input from the IF amplification section 3; P / S separator 4, P / S separator 4 for processing audio signals input from P / S separator 4, and outputting voices to speaker 6 An image processor 7 which demodulates an image signal input from the image signal and performs color tone processing and luminance processing; a CRT driver 9 for displaying the image signal of the image processor 7 on the CRT 10; A synchronization detection unit 16 for detecting a synchronization signal from 7), information on all channels of the television, and an automatic setting channel; A channel memory 14 for storing a channel; a preferred channel storage unit 15 for storing a preferred channel among channel information stored in the channel memory 14 by a preferred channel designation operation of the remote controller 11; and a channel up / down signal. The remote controller 11 and the receiving unit 12 and the channel information stored in the channel memory 14 by the channel up / down signal applied from the receiving unit 12 is provided to the tuner unit 2 It consists of the microcomputer 13 which controls tuning.

Therefore, among the channel information stored in the channel memory 14 by the automatic channel setting method, a synchronization signal is detected from the broadcast signal and automatically stored in the channel memory 14 under the control of the microcomputer 13. do.

Thereafter, when the user ups or downs the channel, the user operates the channel up / down key of the remote controller 11 to designate the preferred channel so that only the broadcasting channels preferred by the user are selected from among the broadcasting channels stored in the channel memory 14. The channel conversion signal is applied to the receiver 12 of the television. Then, the microcomputer 13 receives the channel change signal and controls the channel memory 14 to tune only the broadcast channel automatically set in the channel memory 14 to display the corresponding broadcast signal and simultaneously display the corresponding broadcast signal by the OSD processor 17. Information is applied to the mixer 8 and the channel display of the broadcast channel displayed is displayed on the screen as an OSD screen.

When the channel is continuously changed in this manner and the preferred broadcast channel is displayed, the channel information is stored in the preferred channel storage unit 15 by pressing the storage key provided in the remote controller 11.

When the user wants to watch television while storing the preferred channel information in the separate preferred channel storage unit 15 as described above, the user operates the preferred channel up / down keys, which are not shown in the remote controller 11. Under the control of the microcomputer 13, the channel information stored in the preferred channel storage unit 15 is supplied to the tuner unit 2, and the tuner unit 2 tunes and displays the corresponding channel, thereby converting only the channel that the user prefers. You can watch television.

However, even if the user stores only the channels that the user prefers in the preferred channel storage unit 15 and manipulates the preferred channel up / down keys while converting and watching only the preferred channel, the currently broadcasted program always has his or her favorite broadcast program. Not only that, but also other favorite channels that are not stored in the favorite channel storage 15 may be broadcast their favorite program.

That is, in the case of the preferred channel, the channel map is composed based on the channel, but since the desired program is not always broadcasted in the corresponding channel, when the desired program is broadcasted in another channel, the channel is switched to the channel where the program is broadcasted. Done.

In this case, in order to switch to the corresponding broadcast channel, the user must move up and down by operating the up / down keys several times, or must remember and switch the corresponding channel number, or store the currently broadcast channel in the preferred channel.

If the newly broadcast channel is designated as the favorite channel, the channel map must be newly modified while watching TV, and the modified channel map is fixed and is stored continuously unless it is changed again. There is a problem that the number of.

The present invention was created to solve the above problems, and an object of the present invention is to search for program information (PSIP) that is broadcasted on another channel through a search word while watching one broadcast program, and to select a selected channel from the found channels. The present invention provides a method of setting a channel of a television so that a preference channel can be set according to contents of a user's favorite broadcasting program which is only temporary while watching a television by setting a dynamic channel map.

The present invention for realizing the above object comprises the steps of determining the presence or absence of stored search terms for constructing a dynamic channel map, and entering or saving a new search term in accordance with the presence or absence of the stored search term is determined by Determining a search term, setting a search option according to the determined search term, searching for broadcast program information on another channel according to the set search option, displaying a search result, and displaying a dynamic channel according to the displayed search result. Comprising a step of constructing the map or re-search.

In the present invention, the search option is characterized by including the search interval, the number of times, the degree of matching.

In the present invention, the broadcast program information is characterized in that the event information table (EIT) information and extended text table (ETT) information among the Program and System Information Protocol (PSIP) information.

In the present invention, the dynamic channel map is deleted when the television is powered off.

The present invention thus achieved does not affect the preference channels that are already set up, and searches for program information broadcasted in other channels by entering a search word to set a dynamic channel map to be applied only while watching the current television. By setting the dynamic channel map to the selected channel through, you can conveniently switch channels during the current viewing and delete them when you turn off and restart the television.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. In addition, this embodiment is not intended to limit the scope of the present invention, but is presented by way of example only.

2 is a flowchart illustrating a channel setting method of a television according to the present invention.

As shown here, first, when a viewer wants to set a dynamic channel map while watching television, a dynamic channel map setting process is started by selecting a corresponding menu.

When the dynamic channel map setting process is started as described above, it is determined whether there is a search word stored in order to construct the dynamic channel map (S10).

In this case, if there is a stored search word, the search word is newly input and stored according to the response of whether to use the stored search word again or change (S14) (S12).

However, if there is no stored search word, a new search word for setting a dynamic channel map is input and stored (S12).

After inputting and storing the search word to be searched, a search option is set (S16). That is, the number of times for matching and repetitive search with the search word input from the event information table (EIT) information and the extended text table (ETT) information among PSIP (Program and System Information Protocol) information that is input while changing a channel. And search options such as a search interval when repeating the search.

After setting the search option, a channel matching the input search word is searched through the broadcast program information input while substantially changing the channel (S18).

At this time, since the user is currently watching a broadcast, when a plurality of tuners are installed, the user can search for broadcast program information broadcasted on another channel while watching the current channel.

If no channel is found as a result of the channel search, a banner such as “No channel found” is displayed on the OSD screen (S24). If there is a channel found, the searched channel is displayed as shown in FIG. The name, start time, end time and the like of the broadcast program information is displayed (S22).

Accordingly, the user configures the dynamic channel map by selecting the channel set in the dynamic channel map while viewing the searched result (S26).

However, if the re-search is to be returned to the step of determining the presence or absence of the stored search terms (S10) is to set the new search terms and search options while performing a re-search to configure the desired channel as a dynamic channel map (S30). .

The dynamic channel map set up as described above is stored and operated until the TV is turned off, so that the channel can be set based on the broadcast program to be watched while watching the current television, and it is easy to switch to the channel.

If the television is turned off, the dynamic channel map is also deleted so that it can be set and used by new viewers.

As described above, the present invention searches for program information (PSIP) broadcasted in another channel through a search word while watching a broadcast program, and sets a dynamic channel map to selected channels from the searched channels while watching television. By setting the preferred channel according to the contents of the broadcast program which is preferred by the user, the user can easily search for his / her favorite program and easily switch to the corresponding channel.
