Program information about the channel to be changed when the channel change key signal is input After reading from the memory and outputting, the microcomputer outputs program information only when the current time is not the commercial time by checking the current time of the timer, and the program information provided from the microcomputer OSD (on screen display) And an OSD processing unit for processing and outputting the screen, and a screen for displaying OSD-processed program information provided from the OSD processing unit.

According to another preferred embodiment of the present invention for achieving the above object, in the broadcast program information display method in the TV, (a) processing the KBPS signal from the broadcast signals of each channel received to store the broadcast program information And (b) determining whether a channel change key signal for channel change is input, and (c) if the channel change key signal is input in the step (b) of the channel changed by the channel change key signal. Reading program information; and (d) determining whether the current time is a commercial time, and if not the commercial time, OSD processing the program information read in the step (c) and displaying the program information on a screen. .

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

1 is a block diagram illustrating an apparatus for displaying a program information of a television according to an exemplary embodiment of the present invention, in which an antenna 10 for receiving a broadcast signal and a broadcast of a predetermined channel among the broadcast signals received by the antenna 10 are shown. Through a tuner unit 20 for tuning a signal, a KBPS signal processor 30 for detecting and processing a KBPS signal from broadcast signals tuned and provided by the tuner unit 20, and a KBPS signal processor 30. A video / audio signal processor 40 for processing video and audio signals provided, a key input unit 50 for providing a key signal for channel change, a timer 60 for counting a current time, and a KBPS signal The program information of the KBPS signal provided from the processor 30 is read and stored in the memory 80, and the program information for the channel to be changed when the channel change key signal is input from the key input unit 500 is stored in the memory 80. After reading from the timer, the current time of the timer is checked, and if the current time is not the commercial time, the microcomputer 70 outputs program information and the program information provided from the microcomputer 70 is processed by OSD (on screen display) output. And an OSD processing unit 90 and a screen 100 for displaying OSD processed program information provided from the OSD processing unit 90.

In order to implement the present invention, in the early stage of watching television, after detecting a KBPS signal included in a blanking section of a broadcast signal provided through each channel, program information must be read and stored in the memory 80.

That is, when the television is turned on, the microcomputer 70 generates a control signal to the tuner unit 20 to tune broadcast signals of all channels for a predetermined time so that program information among the KBPS signals provided from the KBPS signal processor 30 is provided. Is detected and stored in the memory 70.

Thereafter, when a channel selection key signal or a channel change key signal is input through the key input unit 50, the microcomputer 70 reads program information corresponding to the changed channel from the memory 80. At the same time, the microcomputer 70 checks the current time of the timer 60 to determine whether the current time is the commercial time. At this time, if the current time is the commercial time, the microcomputer 70 does not output the program information read out from the memory 80, and if it is not the commercial time, the program information is input to the OSD processing unit 90 for a predetermined time. Output for 1 to 2 minutes.

Then, the OSD processing unit 90 processes the program information provided from the microcomputer 70 and provides the screen 100, and the screen 100 displays it so that the viewer can display the information of the program of the channel, for example. To recognize program titles and broadcast times.

On the other hand, the microcomputer 70 may detect the advertising broadcast time from the broadcast times of each program of the program information read from the memory 80. In other words, the predetermined time between the broadcast time and the broadcast time of each program is recognized as the commercial broadcast time. For example, if news is broadcast at 7 o'clock and drama is broadcast at 8 o'clock (which can be seen through program information detected from the KBPS signal), a predetermined time, e. Recognizing that it is time, the microcomputer 70 does not output the program information during this time, so that program information is not displayed during the commercial time.

The broadcast signal tuned to the channel changed by the channel change key signal is provided to the video / audio signal processor 40 through the KBPS signal processor 30. The video / audio signal processor 40 receives the antenna 10 and is tuned by the tuner 20, and then processes the broadcast signal provided through the KBPS signal processor 90 into a video and audio signal so that the audio signal is a speaker (not shown). And the video signal is provided to the OSD processing unit 90. In this case, the OSD processing unit 90 OSD-processes the program information to the video signal for a predetermined time while the program information is provided from the microcomputer 70, and outputs the video signal to the screen when the program information is not provided. .

2 is a flowchart of a method for displaying broadcast program information in a television according to a preferred embodiment of the present invention.

Steps S10 and S20 detect and process program information of programs broadcast through respective channels from broadcast signals of all channels received, and classify and store the program information for each channel.

Thereafter, in step S30, it is determined whether a channel change key signal for channel change is input. If the channel change key signal is input in step S30, the flow advances to step S40; otherwise, the flow goes to step S70. Proceed and maintain the current state.

On the other hand, when the channel change key signal is input in step S30 and proceeds to step S40, in step S40, the program information corresponding to the changed channel among the program information of each channel stored in step S20 is stored. Read out and proceed to step S50.

Then, in step S50, it is determined whether the current time is the commercial time. If the current time is not the commercial time in step S50, the process proceeds to step S60 and the program information read in step S40 is read for a predetermined time. If the current time is the commercial time, the process proceeds to step S70 where the current state is known and progressed without displaying the program information read in step S40. On the other hand, after step S60 and step S70, the flow is returned.

Accordingly, the present invention has an effect of allowing a user to recognize program information of programs broadcast through a channel to be watched, that is, a title and a broadcast period of each program in watching a television.

While the invention has been shown and described with reference to certain preferred embodiments, those skilled in the art will recognize that various modifications and changes can occur without departing from the spirit and scope of the invention as set forth in the claims below.
