Method and apparatus for displaying a recall mode of a television

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for displaying a recall mode of a television, and more particularly, to a television having a recall mode in which information about a channel being watched on television, etc., is displayed on the CRT as an OSD. The present invention relates to a method and apparatus for displaying a recall mode of a television in which a viewer can only view a desired recall menu in the recall mode by changing the menu.

Recently, when a broadcaster broadcasts a television, information about each program, that is, teletext data, is transmitted to a specific frequency band of the broadcast signal and transmitted through a data decoder that decodes the signal on a television receiver. By detecting information about a broadcast program, it provides rough information on the start and end time of the program or the contents of the program.

Fig. 1 shows a block diagram of an example of the circuit configuration of a general television receiver equipped with the data decoder.

As shown in FIG. 1, a television (TV) receiver includes an antenna 1, a tuner 2, a data decoder 2 ′, an IF amplifier 3, a P / S separation unit 4, and voice detection. 5, an image detector 6, an audio processor 10, an OSD generator 13, an image processor 14, a mixer 15, a remote controller 7, a receiver 8, a controller 9 And a memory 9 ', a voice amplifier 11, a speaker 12, a CRT driver 16, and a CRT 17.

The broadcast signal of the airwave is received by the antenna 1, and the broadcast signal received by the tuner 2 controlled by the control unit 9 is tuned. The IF amplification part 3 generally constitutes a chroma IC to a main IC, and amplifies an intermediate frequency (IF) signal output from the tuner 2, and the P / S separation part 4 includes a surface acoustic wave filter for the intermediate. The frequency IF is divided into an image intermediate frequency PIF and an audio intermediate frequency SIF.

The voice detector 5 detects a voice signal from the voice intermediate frequency (SIF), and the voice processor 10 detects the detected voice signal based on the control signal of the controller 9, and controls the base and treble. Voice processing such as volume, volume, etc. is performed, and the processed voice signal is amplified by the voice amplifier 11 and output to the speaker 12.

The image detector 6 detects an image signal from an image intermediate frequency (PIF), and processes the color, tint, brightness, etc. according to the control signal of the controller 9 using the detected image signal in the image processor 14. R (Red), G (Green), B (Blue) and luminance (Y) signals corresponding to the video signals are output, and the R, G, B and luminance (Y) signals are generated by the OSD in the mixer 15. By mixing and outputting the R ', G', B 'and OSD blanking signals Y' generated from the unit 13, the CRT 17 receives a predetermined value from the OSD generator 13 through the CRT driver 16. The image is displayed together with the OSD pattern data.

The remote controller 7 is equipped with a recall mode key for the viewer to adjust the output volume, change the channel, or set the recall mode, etc., to remotely control the whole other device, and to transmit an infrared signal, and to receive the infrared signal. 8) the entire apparatus is controlled by the controller 9 in accordance with the electrical code signal by converting and outputting the electrical code signal.

On the other hand, the teletext data is decoded by the data decoder 2 'from the composite video signal transmitted by encoding the teletext data according to the start and end time of the program or the contents of the program, and the decoded teletext data. Is stored in the memory 9 'configured of the E ² PROM by the controller 9 at the time of power input, channel change, program change or periodically.

Thereafter, when the power source of the television is inputted or when the channel is changed or when new teletext data is input, the information on the broadcast program is displayed on the CRT 17 by the control unit 9.

2 is a flowchart showing the configuration of a recall mode display method of a conventional television.

In the recall mode of FIG. 2, the preset recall menu is loaded in step S1, and if the preset recall menu is loaded in step S1, the preset recall menu loaded in step S2 is displayed. You will be returned to the menu.

That is, when the viewer sets the recall mode through the recall mode key provided on the remote control or selects the main menu and sets the recall mode of the submenu, the remote controller sends an infrared signal, receives it from the receiver, and converts the signal into an electrical code signal. The controller loads a preset recall menu (for example, channel number, time, etc.) in the memory according to the electrical code signal, and then outputs a signal for displaying the loaded preset recall menu.

The OSD generator outputs the OSD pattern data signals R ', G', B 'and OSD blanking signal Y' so that the recall menu preset by the signal is displayed on the CRT. The recall menu preset on the CRT is displayed along with the image, and the recall mode is completed by the control unit, and the menu is returned to the main menu.

However, in a television having a conventional recall mode configured and performed as described above, a preset recall menu is displayed in the recall mode so that a recall menu, which is information that the viewer does not want, is displayed, or a recall, which is information desired by the viewer. The problem is that the menu is not displayed and cannot be viewed.

Accordingly, the present invention has been made to solve such a problem, and to provide a method and apparatus for displaying a recall mode of a television for changing only the recall menu displayed in the recall mode to view only the recall menu desired by the viewer in the recall mode.
