Description

TV magnetic field correction device and method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to magnetic field correction of an electronic device, and more particularly, to a magnetic field correction device and method for a TV, which automatically rotates a system according to whether a magnetic field is detected so that the device can operate regardless of the influence of the magnetic field.

In general, when the TV system is affected by the magnetic field, the image quality is deteriorated, the sound is abnormal, and the tuning is abnormal. Therefore, the TV system does not provide a satisfactory reception environment.

In order to reduce the influence of the magnetic field, all systems have a magnetic shield function.

However, it is not possible to completely exclude the influence of the type and output of home appliances, so a response system is required.

Hereinafter, a TV system according to the related art will be described with reference to the accompanying drawings.

1 is a schematic configuration diagram of a TV system of the prior art.

A schematic configuration of a TV system of the prior art is first composed of a TV system control unit 3 which controls the entire TV system and outputs a TV broadcast signal on the screen, and a TV body configured to receive a user's selection signal. The external input signal processor 4 for processing, the OSD unit 5 for outputting an OSD (On Screen Display) signal under the control of the TV system controller 3, and the tuning control signal of the TV system controller 3 A tuner unit 1 for selectively outputting a broadcast signal, a TV image processor 2 for receiving and outputting TV image data and OSD data of the tuner unit 1, and outputting the image data to the TV image processor 2 It is largely comprised of the external display part 6 which displays an output signal to the exterior.

The TV system configured as described above is controlled by the TV system control unit 3 which controls the whole of the TV system. When the user inputs a control signal such as TV o / off and channel selection, the user inputs a selection control signal using a remote controller. The external input signal processing unit 4 processes this, and the TV image data selected by the tuner unit 1 and the OSD data of the OSD unit 5 are processed by the TV image processing unit 2 according to the processed signal. Displayed in section 6.

In such a TV system, various services have been attempted using various information including broadcast information transmitted between program signals.

Broadcasting methods using broadcast information data may be classified into a VPS (Video Programmable System) and a PDC (Program Delivery Code).

The VPS transmits broadcast program information data on a 16th line existing on an equalized pulse section that does not appear on the screen among broadcast signals, and receives the VPS signal from a receiver (TV / VCR). It is possible to recognize the information of the broadcast signal being received.

In addition, the PDC is developed and used in Europe, such as Germany, the United Kingdom, Australia, and the difference from the VPS transmits the Teletext information data, and similarly, the teletext data information is loaded on the equalization pulse section. To give.

In the ATS (Auto Tuning System) operation using PDC / VPS data in a TV system, the data is applied to the tuner unit 1 while gradually increasing the value from the lowest value of the tuning data.

The tuner unit 1 receives data from the TV system control unit 3 and tunes the corresponding frequency. The tuner unit 1 transmits a video signal formed at this time to a PDC / VPS decoder through a data transmission line and transmits H-synchronous and AFT data. Is output to the TV system controller 3 to perform a tuning operation.

However, if the influence of the magnetic field generated in the peripheral device in the tuning operation and watching the program according to the tuning, such a function is not made correctly.

Such a conventional TV system has the following problems.

In the conventional TV system, it is difficult to perform an accurate function because the response system for the influence on the magnetic field is not complete.

It is inefficient and inconvenient to the user in terms of device operation because accurate channel classification is not made in tuning operation.

The present invention has been made to solve the problems of the conventional TV system, and according to whether the magnetic field is detected, the system displays the switching direction of the system to the outside or automatically corrects the influence of the magnetic field regardless of the influence of the magnetic field. An object of the present invention is to provide an apparatus and a method for compensating a magnetic field of a television, which enables an apparatus to operate.
