The present invention is an image character information position that converts the character information by OSD (On Screen Display) displayed on the screen of a television receiver or a monitor to any pixel position desired by the user. It relates to an inverter.

In general, an electrical signal representing image information is referred to as a composite image signal. A color image signal is composed of a luminance signal (Y signal) and a color signal (C signal) superimposed, and the composite image signal is a blanking signal (blanking signal). ) And the synchronizing signal, and in the case of a color image signal, the color burst is added. The synchronization signal is composed of a horizontal synchronizing signal and a vertical synchronizing signal. The retrace clear signal scans the screen horizontally in the horizontal direction and vertically in the vertical direction. The return line of this scanning is called a retrace. When the retracement is not good when it is displayed on the screen, it is called blanking, and the blanking signal of horizontal or vertical scanning is called horizontal retrace signal and vertical retrace signal, respectively. In this way, various additional governments are broadcast by using a video in the resin retrace signal. The most representative one is text broadcasting. In addition, during the 525 lines of vertical retrace period, the character broadcast is performed in the fields of the 14H, 15H, 16H, and 21H lines as an insertion signal. Therefore, the character information by the OSD (On Screen Display) displayed on the screen is fixed to one pixel and cannot be moved to the pixel desired by the user. Therefore, the text information obscures the image, so there was a disadvantage that the desired image could not be seen.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an apparatus for converting an arbitrary pixel into a desired position.

In order to achieve the object of the present invention, by changing the oscillation frequency to a condition that can change the frequency from the outside to move the character position on a certain pixel to determine whether the OSD information and the signal processing whether or not the character on the screen Characterized in that the information can be freely converted, and the configuration according to the accompanying drawings as follows.

1 is a block diagram of the present invention, which is a stage having a condition capable of converting a VCO (Voltage Control Oscillator) arbitrarily from the outside, and is determined by data determined by changing a VCO in a horizontal drive section within a 1H section. A variable oscillator 10 capable of changing the frequency to shift the image character information on the processed OSD (On Screen Display) and a frequency converted by the VCO adjustment of the variable oscillator 10 are processed to A variable oscillation processor 20 for processing a conversion frequency compared to a reference voltage, a video unit 30 for processing a signal passed through an amplification and a filter of a magnetized signal read from a head of a VCR, and a variable frequency Comparing the output of the OSD processing unit 40 and the OSD processing unit 40 to extract the information of the desired position by detecting the comparison level and the comparison with the timer microcomputer unit 70, the output is compared with the external input. A switch unit 50 that determines whether or not, a television / monitor unit 60 that visually shows the output signal, and a timer that exchanges clock and data with each other to determine whether or not signal processing is consistent with OSD information and information. The microcomputer part 70 was comprised.

Referring to the operation of the device for converting the position of the image text information of the present invention to the pixel desired by the user in detail as follows.

Referring to FIG. 1, the variable oscillator 10 has a condition capable of converting the VCO arbitrarily from the outside, and the image on the OSD processed by the predetermined data by changing the VCO in the horizontal driving section within the 1H section. Data can be converted to shift character information. This may vary the frequency with a crystaal oscillator (OSC) connected to the variable oscillator (10). The variable oscillation processing unit 20 processes the converted frequency in comparison with the reference voltage of the OSD due to the VCO adjustment of the variable oscillation unit 10.

The OSD processing unit 40 receives the synchronization signal, the composite synchronization signal, and the oscillation frequency of the variable oscillation unit 10 from the video unit 30, which amplifies the magnetized signal read from the head and processes the filtered signal. The pixel is read at a predetermined information and a variable oscillation frequency, the information is compared with the timer microcomputer unit 70, and the information is drawn at a desired position.

The timer microcom unit 70 exchanges clock and data with each other to determine whether signal processing with OSD information is consistent with information.

The operation relationship between the timer microcomputer 70 and the OSD processor 40 is the same as the flowchart shown in FIG. That is, the timer microcomputer 70 judges the presence or absence of the character information in the image and checks whether the character information is processed at the desired pixel position when the character information is present. If it is determined that the character information is desired to be transferred to another position, the character information is adjusted and adjusted by the variable oscillator 10 at the frequency corresponding to the data pixel of the desired position from the OSD processor 40. Check that the variable-adjusted character information is being processed at the pixel position desired by the user, and end the position conversion.

The switch unit 50 compares the output of the OSD processing unit 40 with an external input to determine whether to output. Therefore, the signal output to the image of a television, a monitor, etc. is visually represented.

The present invention changes the oscillation frequency to an arbitrarily determined OSD character position through the variable oscillation unit 10 and the variable oscillation processing unit 20 to convert the character information displayed on the image into a desired pixel position, and synchronizes the oscillation frequency to match the OSD. The information can be converted to any pixel position of the image to provide an improved convenience to the user.
