The present invention relates to a channel switching method of a television, and more particularly, when a program is terminated early according to a regular broadcast schedule while watching television, the channel is continuously searched for through the broadcast information or is searched for early termination. The present invention relates to a channel switching method of a television for receiving a channel information and automatically switching to a corresponding channel so that a user can continuously watch a corresponding program relay even if the user does not search for a channel for continuous viewing.

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 synchronizing signal of the composite video signal received before using the television and automatically retrieving the channel information that can be received, the channel map is constructed. 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.

1 is a block diagram showing a general digital television.

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 selected and tuned from the tuner section 2, and P for separating the video signal and the audio signal from the composite video signal input from the IF amplifier 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, and an image processor 7 Synchronization detection unit 16 for detecting a synchronization signal from A channel memory 14 storing a channel map for a channel, a remote controller 11 and a receiver 12 for providing a channel up / down signal, and a channel memory by a channel up / down signal applied from the receiver 12; The microcomputer 13 receives channel information of the channel map stored from (14) and provides it to the tuner unit 2 to control tuning.

Therefore, the synchronization signal of the composite video signal received by the synchronization detection unit 16 for all channels is automatically detected and the channel information that can be received is automatically retrieved to construct and store a channel map in the channel memory 14.

Thereafter, when the user up / downs the channel, the user tunes sequentially according to the channel map stored in the channel memory 14 to display the corresponding broadcast signal, and at the same time, the channel information is applied to the mixer 8 by the OSD processing unit 17 and displayed. The channel display of the broadcasting channel is displayed on the screen as an OSD screen.

In addition, the digitization of the broadcast signal is transmitted by multiplexing and transmitting PSIP (Program and System Information Protocol) information in the vertical retrace period of the TV video signal, or by using a separate channel for character information, image information, product information, Data broadcasting, which is a new media service that provides multimedia information such as information on a broadcast program (also known as an electronic program guide (EPG)), can be implemented.

When watching a program that does not keep the end time, such as sports relay using the television, if the game does not end in accordance with a predetermined broadcast time, sports broadcasts are terminated early for regular broadcasting and regular broadcasts are sent out.

However, if you want to continue watching sports, other channels, such as sports specialty channels, may continue to broadcast until the end of the game, so check the broadcast information of other channels to find the channels that relay the same game. There was an inconvenience to find and switch to that channel.

The present invention was created to solve the above problems, and an object of the present invention is to search for a channel where the program is continuously relayed through broadcast information when the program is terminated early according to a regular broadcasting schedule while watching television. Or channel information according to an early termination of the channel, the user can automatically switch to the corresponding channel even if the user does not search the channel for continuous watching so that the user can continuously watch the program relay.

The present invention for achieving the above object is the step of determining whether the broadcast program being viewed, the step of determining whether the end information is included when the broadcast program is terminated, and if the end information is normal termination or early termination? And determining whether the channel information of the same broadcast program is continuously broadcast in the case of early termination, and searching EPG information when the termination information is not included or the channel information is not included in the termination information. Searching for a channel in which a program is continuously broadcast; and changing to a corresponding channel according to whether to switch to a corresponding channel when a search result broadcasting channel of the channel continues to be broadcast or channel information is included in the end information. Characterized in that made.

In the present invention, the broadcast program is characterized in that the sports relay broadcast.

In the present invention, whether or not to switch the channel is characterized in that notified through the OSD screen.

In the present invention, if the normal termination or the search result broadcast channel does not exist or channel selection is not selected, further comprising the step of maintaining the currently viewed channel.

According to the present invention as described above, when the broadcast is terminated while watching a sports broadcast broadcast, if the end information is included, the end information determines whether the same broadcast program is continuously relayed on other channels and determines whether to include the channel information automatically. If it is changed to or the end information is not included, the EPG information is searched to search for a channel where the same broadcast program is continuously relayed, and then automatically changes to the corresponding channel so that the broadcasted broadcast can be continuously watched.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings, and the same parts as in the prior art use the same reference numerals and names. In addition, the present embodiment is not intended to limit the scope of the present invention, but is presented by way of example only and those skilled in the art will be capable of many modifications within the technical spirit of the present invention.

2 is a flowchart illustrating a channel switching method of a television according to an embodiment of the present invention.

First, while watching a broadcast program by selecting a channel on the television, it is determined whether the broadcast program being viewed has ended (S10).

At this time, the broadcasting program to be watched is a live sports broadcasting program. In case of a broadcasting program whose end time is not accurate according to a game situation, the broadcasting program being watched is terminated in order to terminate the sports broadcasting that was relayed in a regular broadcasting relationship and to send the regular broadcasting. The case is judged.

When the broadcast program being watched is terminated as described above, the EPG information is checked to determine whether the end information is included (S12).

In this case, when the termination information is included, when the program that was broadcasted is terminated normally by determining whether it is early termination or normal termination, that is, when the sporting event is ended normally, the current watching is performed without performing any operation for automatic channel switching. The state is maintained (S14).

However, if the early termination information is included, it is determined whether the channel information continuously broadcasting the same broadcast program as the broadcast program that is currently terminated early is included (S16).

In other words, if the broadcast program that is currently being broadcast by the broadcasting station is terminated early and the same broadcast program is continuously broadcasted by another channel such as a sports professional channel, the channel information is displayed to the viewer by transmitting the broadcast channel through the channel information. It is asked whether to switch to the corresponding channel (S22) (S24).

In this case, if the channel switching is selected, the channel is changed to the corresponding channel so that the same broadcast program can be continuously viewed (S26).

On the other hand, when the broadcast program that was being watched was not terminated information included (S12), or it was terminated early as a result of determining that the end information was included (S14), but the channel information for continuing to relay the same broadcast program is not included (S16). In step S18, the EPG information is searched based on the program title and the information about all the channels.

When searching for the same broadcast program by searching the EPG information, the viewer is asked whether to switch to the corresponding channel searched on the OSD screen (S22) (S24).

In this case, if the channel switching is selected, the channel is changed to the corresponding channel so that the same broadcast program can be continuously viewed (S26).

However, if the same broadcast program is not searched (S20) or if the channel is not desired to be switched even if the search is performed, the current channel is maintained (S24).

As such, when the currently viewed broadcast program is terminated early, the program is searched for whether the same broadcast program is broadcasted through EPG information and channel information so as to be automatically switched to the corresponding channel so that the broadcast program can be continuously watched.

As described above, according to the present invention, if a program is terminated early according to a regular broadcasting schedule while watching television, the user may continue to search for a channel where the corresponding program is continuously relayed through broadcast information or receive channel information according to early termination. Even if the channel is not searched for viewing, the channel is automatically switched to the corresponding channel, so that the user can conveniently watch the program broadcast continuously.
