Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sequential scan signal automatic output device in a DVD player, comprising: a component output jack connected to a component input jack (Y, Pb, Pr) located on one side of a specific product through a component connection line, and a component output. When the jack and the component input jacks are connected by mutual component connection lines, a level detector detects a high level and provides a sensed high level, and automatically converts into a sequential scan mode according to the detected high level to sequentially scan. It includes a microcomputer for controlling to output a signal. Therefore, there is an effect that can solve the cumbersome problem to be performed while always changing the video settings to the sequential scan mode on the existing main setup menu.

Description

Sequential scan signal automatic output device in DVD player {PROGRESSIVE SCAN SIGNAL AUTOMATIC OUTPUT APPARATUS IN DVD PLAYER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a progressive scan signal automatic output device in a digital versatile disc (DVD) player. In particular, when a component input / output jack is connected by a mutual line, the present invention detects the progressive scan signal. The present invention relates to a device for automatically converting and outputting data.

Typically, the scanning method of a DVD player is divided into an interlacing scan and a progressive scan.

The dual interlaced scan transmits the screen while scanning the odd lines and the next even lines. The sequential scan transmits the screen while scanning the whole screen at once.

Of these methods, DVD players with progressive scan feature will not be able to view the screen unless you change the video setting to progressive scan mode in the main setup menu when the user connects the television to the component output jack of his player. .

Thus, the user has a cumbersome problem of always changing the video setting to the sequential scan mode on the main setup menu when the component input / output jacks are connected by mutual lines.

Accordingly, the present invention has been made to solve the above-described problems, the object is that when the component input / output jacks are connected by a mutual component connection line, it detects this and automatically converts to a sequential scan mode to convert the sequential scan signal The present invention provides a sequential scan signal automatic output device in a DVD player capable of outputting.

In order to achieve the above object, a sequential scan signal automatic output device in a DVD player according to the present invention has a component output connected to a component input jack (Y, Pb, Pr) located on one side of a specific product through a component connection line. When the jacks, component output jacks and component input jacks are connected by mutual component connection lines, a level detector for detecting a high level and providing a sensed high level, and a sequential scan mode automatically according to the detected high level. It characterized in that it comprises a microcomputer for converting and controlling to output a sequential scan signal.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a sequential scan signal automatic output device in a DVD player according to the present invention, and the component connection line of the component input jacks (Y, Pb, Pr) S4 located on one side of the rear surface of the television (S1). When the component output jack 1 and the component output jack 1 and the component input jack S4 which are interconnected through (S3) are connected by the mutual component connecting line S3, at a high level (for example, at 0V). Level sensing unit 2 for sensing the level converted to 5V and providing the detected high level to the microcomputer 3, and automatically converting to the sequential scan mode according to the high level provided from the level sensing unit 2 And a microcomputer 3 for controlling the output of the sequential scan signal.

Based on the above configuration, the operation of the sequential scan signal automatic output device in the DVD player according to an embodiment of the present invention will be described in more detail.

First, referring to FIG. 1, the component input jacks (Y, Pb, Pr) S4 located on one side of the rear surface of the television S1 and the component input jacks S4 located on one side of the DVD player S2 are connected to each other. It is connected by (S3).

Then, the level detector 2 detects a high level (for example, a level converted from 0 V to 5 V) when the component output jack 1 and the component input jack S4 are connected by the mutual component connection line S3. Then, the detected high level is provided to the microcomputer 3.

The microcomputer 3 controls to output a sequential scan signal by automatically converting to a sequential scan mode according to the high level provided from the level sensor 2.

Here, when the DVD player S2 is connected to an output jack other than the component output jack 1, an interlacing scan signal set as the default of the player is output.

As described above, according to the present invention, when the component input / output jacks are connected by mutual component connection lines, the present invention detects them and automatically converts them to the sequential scan mode, thereby converting the video settings on the existing main setup menu to the sequential scan mode. There is an effect that can solve the cumbersome problems that must be performed while always changing.

1 is a block diagram of an apparatus for automatically outputting a sequential scan signal in a DVD player according to the present invention.
