Description

How to adjust screen position on digital television receiver

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital television receiver (hereinafter referred to as " TV ") receiver, and more particularly, to a method of adjusting the position of a screen displayed on a receiving tube of a digital television receiver.

In general, a digital TV receiver has vertical and horizontal direction keys for adjusting the position of the screen displayed by the receiving tube. When the user wants to adjust the position of the screen, the digital TV receiver can adjust the position of the screen using the vertical or horizontal direction keys. To make it work.

However, in order to adjust the position of the screen displayed on the receiving tube of the digital TV receiver to a desired position by using a vertical or horizontal direction key as described above, a number of key manipulations are required and accurate adjustment is difficult.

As described above, when the user wants to adjust the position of the screen displayed on the receiving tube of the digital TV receiver, the position of the screen displayed on the receiving tube of the digital TV receiver has to be adjusted to a desired position by using the vertical or horizontal direction keys. Because of the multiple key operation and accurate adjustment was also a problem.

Accordingly, an object of the present invention is to provide a method for adjusting the position of a screen displayed on the receiving tube in two dimensions at a time by using a pointing device.

1 is a block diagram of an HDTV receiver to which the present invention is applied;

2 is a flow chart according to an embodiment of the present invention.

The present invention for achieving the above object is to calculate the coordinate values on the screen of the start point and the end point that the pointing device moved in the screen position adjustment mode of the digital TV receiver, the position of the screen displayed on the water pipe of the digital television receiver And display by moving to a position.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Many specific details are set forth in the following description and in the accompanying drawings, in order to provide a more thorough understanding of the present invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

FIG. 1 is a block diagram of a high definition television (HDTV) receiver employing a moving picture expert group (MPEG) standard as an example of a digital TV receiver to which the present invention is applied. Referring to FIG. 1, a tuner 102 inputs a digital TV broadcast signal received through an antenna 100 to tune a channel under control of a microprocessor 124, and selects an IF according to the tune. Outputs Intermediate Frequency) signal. The IF module 104 converts the IF signal output from the tuner 102 into a baseband signal. The channel decoder 106 reproduces the data bit stream by channel decoding the baseband signal output from the IF module 104. The TS (Transport Stream) decoder 108 separates audio data, video data and additional data from the data bit string reproduced by the channel decoder 106. The audio data among the separated data is applied to the audio decoder 110, decoded according to the MPEG standard or the Dolby AC-3 standard, processed by the audio processing unit and the output unit 112, and then the speaker 114 is moved. Is output through voice. The video data is applied to the video decoder 116, decoded according to the MPEG standard, and applied to the OSG (On Screen Graphic) Mixer (118) to be combined with OSG data under the control of the microprocessor 124 to process the video and After processing at the output unit 120 is output on the screen through the water pipe (122). The OSG data is data for the microprocessor 124 to display various types of information on the screen as a graphic or a text.

In addition, a key panel 130 and an IR receiver 134 are connected to the microprocessor 124 which is a control unit of the HDTV receiver through a user interface 128. The microprocessor 124 performs an operation according to a command input from the IR remote controller 132 through the key panel 130 or the IR receiver 134 according to a program stored in the memory unit 126. In addition, the memory unit 126 may include a read only memory (ROM) for storing a program of the microprocessor 124 and a random access memory (RAM) for temporarily storing data according to program execution of the microprocessor 124. Memory) and EEPROM (Electrically Erasable And Programmable ROM) for storing various reference data.

FIG. 2 is a flowchart illustrating a process of two-dimensionally moving a position of a screen displayed on a receiving tube of a digital TV receiver using a pointing device in accordance with an embodiment of the present invention. The operation according to the flowchart of FIG. 2 is programmed in the memory unit 126 to be performed by the microprocessor 124 of FIG. An embodiment of the present invention will now be described in detail with reference to FIGS. 1 and 2.

In general, digital TV receivers are currently displaying a menu corresponding to each function on the screen using an OSD (On Screen Display) so that users can easily understand and use various functions. The user can designate and execute the menu item by moving the cursor on the screen and placing the cursor on the desired menu item. According to an embodiment of the present invention, a screen position adjustment mode for adjusting the position of the screen displayed on the receiving tube of the digital TV receiver is installed as a new option in the menu item.

Referring to the above description, the flow chart of FIG. 2 will now be described again. First, when the user wants to adjust the position of the screen displayed on the HDTV receiver, the menu items are inputted by the menu items. To be displayed on the screen. The cursor is moved to select a newly provided screen position adjustment mode according to an embodiment of the present invention. In this case, the user may use the key panel 130 provided in the HDTV receiver or the IR remote controller 132 in selecting the position adjustment mode. In response, the microprocessor 124 proceeds from step 200 to step 204 of FIG. 2 to display a test pattern screen on the receiving tube of the HDTV receiver. On the contrary, if the screen position adjustment mode is not set in the HDTV receiver in step 200, the microprocessor 124 proceeds to step 202 and subsequently performs a corresponding operation according to a key input from the user. In step 204, the user views the test pattern screen displayed on the receiving tube of the HDTV receiver and moves the pointing device to move the test pattern screen to a desired position on the screen. In the above, the pointing device may be, for example, a “mouse” or the like. The microprocessor 124 then proceeds to step 206 to calculate coordinate values on the screen of the point where the pointing device is moved. Next, the microprocessor 124 moves and displays the test pattern screen to the position on the screen calculated in step 206. Therefore, the user can easily adjust the position of the screen by using the pointing device to the desired position. The microprocessor 124 proceeds to step 210 and checks whether a key indicating completion of position adjustment has been inputted, and terminates execution if a position adjustment completion key is inputted, otherwise the position adjustment completion key is inputted. If not, return to step (208) and perform steps (208) to (210) again.

As described above, the present invention provides an advantage that the user can easily adjust the position of the screen to a desired position by using a pointing device when adjusting the position of the screen displayed on the receiving tube of the digital TV receiver. have.
