The present invention relates to a sub-screen position control apparatus of a multi-screen television, and more particularly, when the OSD is displayed while the sub-screen is being viewed, the display position of the sub-screen is detected from the current position. The present invention relates to a method for automatically shifting a sub-screen position during an OSD display of a multi-screen television to be automatically shifted to another position.

Televisions that reproduce video signals and audio signals of broadcast programs transmitted from a plurality of broadcasting stations have been developed from a one-channel reproduction method using a tuner, and two tuner types are adopted by the first and second tuners. The broadcast signal of the channel tuned by this is displayed on the main screen.

On the other hand, the broadcast signal of the channel tuned by the second tuner is displayed on the sub-screen, so that multi-screen processing is possible. Based on this, the two-tuner television can display a single screen or a screen by the multi-screen. Simultaneous viewing of multiple channels is possible (hereinafter, this function is simply referred to as picture-in picture).

As described above, the PIP television can facilitate simultaneous viewing or channel search through a plurality of multi-screens, and also provides text guidance, volume of various operations and settings by OSD (on-screen display) display. Simultaneous scanning of characters and figures is possible, such as the state of being provided with a lot of convenience.

However, according to the prior art idea, the main screen of the PIP television as described above is often displayed by overlapping various information in the OSD, so that the PIP screen and the OSD are overlapped to mutually identify each other. It is often the case to make it difficult.

Since the OSD is displayed in the color of the Loyu, when it is matched with the color of the PIP screen, there is a problem that it becomes more difficult to identify.

Accordingly, the present invention has been made to solve the problems associated with the prior art as described above.

According to the present invention, when the OSD is displayed while the PIP broadcast is turned on, the PIP screen is automatically moved to a position that does not overlap each other so that the viewer distinguishes the PIP screen and the OSD and accurately recognizes the OS. It is an object of the present invention to provide a method for moving a sub-screen position during display of an OSD of a multi-screen television.

As described above, the sub-screen position shifting device in the OSD display of the multi-screen television, which is achieved to achieve the object of the present invention, includes an OSD display position of the television which is capable of multi-screen display by a plurality of tuners. When the PIP display position is matched and matched, the controller including the microcomputer which moves the PIP screen and moves the PIP screen to its original position after the OSD disappears generates an output for moving the PIP screen position. As a result, when the image multiple processing is performed, the position shift of the PIP screen is automatically accompanied when the OSD and the PIP screen overlap.

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

In a method comprising a plurality of tuners and displaying a broadcast signal received by the tuner on a main screen and a sub-screen, and superposing an OSD display on the main screen,

The PIP screen is moved when detecting the display of the OSD, and when the position of the PIP screen coincides with the position of the OSD during the display of the OSD by using the caster for detecting whether the PIP screen overlaps with the OSD0. When the OSD disappears, the sub-screen position is automatically shifted during the OSD display of the multi-screen television which includes moving the PIP screen to its original position.

The effects of the present invention having the technical spirit as described above will be described in more detail below.

First, the block diagram of FIG. 1 will be described.

The first and second tuners 10 and 20 receive broadcast signals transmitted by a plurality of broadcast stations under the control of the control unit 33, and receive the broadcast signals to display the first tuner and the PIP screen for the main screen. Act as a second tuner for playback.

The broadcast signals received through the first and second tuners 10 and 20 are separately processed into audio and video signals.

11 represents a voice IF module for detecting and frequency converting and amplifying a voice signal included in the broadcast signals of the main channel and the sub channel selected by the tuners 10 and 20, 12 denotes a TSGHWMD width portion, and 13 denotes a voice. The audio signal processed by the IF module 11 (that is, the audio signal of the main channel) is reproduced by the control term reproducing process of the control unit 12 (e.g., volume control and switching process of the audio signal when switching between the main channel and the sub channel). And the like, and 14 denotes a sound signal processing unit 13, which is amplified with a constant amplification to the sound signal processed by the sound signal processing unit 13, and applied to a speaker device (not shown or reproduced by a Remophone in the case of PIP) as an audio output device. An audio output unit provided as an audio signal Aout is shown.

These voice processing paths are composed of equal numbers of two channel tuners, respectively.

In FIG. 1, reference numerals 21, 22, 23, and 24 denote video signals or external video signals included in a broadcast signal tuned in a channel tuned by the first or second tuner 10 or 20. And an IF module denoted by 21 to IF convert the video signal included in the broadcast signal of the channel tuned by the first and second tuners 10 and 20, and convert the image amplification unit 22 into an IF module. Through this signal is amplified.

In addition, the image multiple processing unit 23 denotes the main screen and the sub picture under the image multiple mode (PIP function) inputted by the PIP selection button of the control signal input unit 40 with respect to the image signal provided from the image IF module 21.
