Abstract

PURPOSE: An image signal selecting apparatus is provided to immediately select one among plural image signals as occasion demands by a one-touch type without scanning plural image modes. CONSTITUTION: A multiple SYNC(SYNChronization) separator(102) receives video signals from plural outside devices and separates vertical SYNC signals from the received video signals. An integrator(104) integrates plural vertical SYNC signals from the multiple SYNC separator and outputs an outside device recognition signal. A control member(106) controls the operation of a video processor(116) for processing video signals from the plural outside devices so that the video signal corresponding to the outside device recognition signal is processed by one touch.

Description

Image signal selector {IMAGE SIGNAL SELECTOR}

The present invention relates to an image signal selection apparatus, and more particularly, to an apparatus for selecting one image signal desired by a user from a plurality of external image signals by one touch method.

As display devices of new peripheral video devices are diversified, researches and developments are being conducted to receive more and more external input terminals. Accordingly, consumers are required to receive and view images of various external devices. In order to select a desired mode among many video modes, inconvenience of inconvenience and time allocation in various office tasks are required. Or there are cases where the device is received due to a lack of understanding by the user.

For example. In the method of rotating Video 1 / Video 2 / Video 3 / Component 1 / Component 2 / PC, the image of Video 1, 2, 3, Component 1, 2 when the consumer connects to the PC and wants to view the monitor. After scanning the mode, you can select the desired PC mode. That is, there is a disadvantage in that it takes a lot of time and effort and a button operation of a main body key or a remote controller until the consumer selects a desired video mode. Another example of the related art is a method of performing an external device mode switching through a low / high port in a microcontroller by performing a contact switch operation using a predetermined voltage when connecting each external device input jack. According to this conventional method, in many cases, consumers in a home may connect a video / DVD / PC / digital set-top box to an image receiver input terminal such as a TV. In this case, if only the DVD is to be powered on to watch component 1 (the other external device is powered off), the same operation as in the case of the first prior art should be performed. Because the jacks of all external devices are connected, other external devices except the DVD are powered off but the jacks are connected. You must scan.

Accordingly, an object of the present invention is to provide an apparatus for selecting one image signal desired by a user in a one-touch manner among a plurality of external image signals.

The present invention to achieve the above object

A multiple sync separator for receiving video signals from a plurality of external devices and separating vertical sync signals from the received video signals;

An integrator which integrates the plurality of vertical synchronization signals from the multiple synchronization separator and outputs an external device recognition signal; And

And a controller for controlling an operation of a video processor for processing video signals from a plurality of external devices to process the video signal corresponding to the external device recognition signal from the integrator with one touch. Provide an optional device.

Hereinafter, an image signal selection device according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a video signal selection device according to a preferred embodiment of the present invention.

The video signal selection device includes a multiple sync separator 102, an integrator 104, and a controller 106. The multiple sync separator 102 receives video signals from a plurality of external devices and separates vertical sync signals from the received video signals.

The integrator 104 integrates the plurality of vertical sync signals from the multiple sync separator 102 and outputs an external device recognition signal. The controller 106 controls the operation of the video processor 116 to process video signals from a plurality of external devices in order to process the video signal corresponding to the external device recognition signal from the integrator 104 with one touch. do.

Hereinafter, the operation of the video signal selection device according to an embodiment of the present invention.

Images of only the third external device 108 are displayed among the complex external input devices, that is, the first external device 108, the second external device 110, the third external device 112, and the fourth external device 114. To see, the Y image signal of the third external device 108 is input to the multiple synchronization separator 102 so that the separated vertical synchronization signal is provided to the integrator 104. The integrator 104 integrates the vertical synchronization signal and inputs it to a designated port of the controller 106 to recognize an image signal of the external device. Thereafter, when the user switches to the external device video mode using the remote controller, the user immediately switches to the third external device 112. The controller 106 switches to the third external device 112 and simultaneously controls the video processor 116 to process the image of the third external device 112 and display the same through the display unit 118. If you want to select another external device to watch, there is an advantage that you can immediately watch in the desired screen mode with a single key operation by switching to the above method.

As described above, when the image selection device according to the present invention is applied to an image display device such as a TV, the user may select the desired image mode immediately without having to scan the image modes of a plurality of stages, and the complexity may vary. Users can reduce the confusion and inconvenience of peripheral devices.

While the invention has been shown and described with respect to certain preferred embodiments thereof, the invention is not limited to the embodiments described above, but in the field to which the invention pertains without departing from the spirit of the invention as claimed in the claims. Any person with ordinary knowledge will be able to make various modifications.
