Multi-image generator that provides segmented images in multivision {Apparatus for generating and providing multivision with multi video}

The present invention relates to a multivision system, and more particularly, to a multivision system capable of displaying a single image by combining a plurality of displays.

Due to the lower prices of displays and the increased visual entertainment of the general public, multivision, which was previously treated only as a work of art, is now universal. As a result, multi-vision can be encountered in public places such as airports, stations, sports stadiums, and the like.

Accordingly, a search for a method for generating a variety of images to be displayed through an increasing multivision is requested.

On the other hand, the multi-vision generates a split-image by dividing the received image, and displays the generated split-image. Since the split-image is generated in the multivision, if the user wants to change the generated split-image, the user must move to the place where the multi-vision is installed, which causes inconvenience to the multi-vision operator.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a multi-image generating apparatus capable of generating a variety of multi-images to be displayed through multi-vision.

In addition, in changing the multi-image to be displayed through the multi-vision, it is not necessary to move to the place where the multi-vision is located, there is an advantage that the management is easy and the management cost is reduced. In addition, it is possible to simplify the configuration of the multi-vision system, there is an advantage that can reduce the system manufacturing cost.

Hereinafter, with reference to the drawings will be described the present invention in more detail.

1 is a diagram illustrating an example of a multi-vision system to which the present invention is applicable. As shown in FIG. 1, a multivision system is constructed of a multi-image generating apparatus 100 and a multivision 200.

The multivision 200 is constructed by arranging / stacking a plurality of displays in a desired shape. In FIG. 1, the multi-vision 200 is illustrated as being implemented with nine displays 200-1 to 200-9 arranged / stacked in three rows by three columns, but this is merely exemplary.

There is no limitation on the number of displays constituting the multivision 200 and the stacking / stacking method. For example, it is also possible to implement multi-vision 200 by arranging / stacking 16 displays in four rows by four columns. On the other hand, the display constituting the multi-vision 200 is not necessarily arranged / stacked in a square, it is a matter of course that the multi-vision 200 can be implemented by arranging / laminated the display in a variety of shapes.

The multi-image generating apparatus 100 is a device for generating a multi-image and transmitting it to the multivision 200. The multi-image refers to a set of images to be displayed on each of the displays 200-1 to 200-9 constituting the multivision 200.

In the multi-vision system illustrated in FIG. 1, the multi-image generated by the multi-image generating apparatus 100 may include 1) an image-1 and 2) to be displayed on the display-1 200-1. Image-2 to be displayed on 200-2), 3) image-3 to be displayed on display-3 (200-3), ..., 9) set of image-9 to be displayed on display-9 (200-9) to be.

The multi-image generating apparatus 100 transmits the images constituting the multi-image to the displays 200-1 to 200-9, respectively. Specifically, the multi-image generating apparatus 100 1) delivers image-1 to the display-1 200-1, 2) delivers image-2 to the display-2 200-2, and 3) Image-3 is delivered to display-3 (200-3), ..., 9) Image-9 is delivered to display-9 (200-9).

2 is a diagram showing another example of a multi-vision system to which the present invention is applicable. The multivision system illustrated in FIG. 2 further includes converters 300-1 to 300-9 in addition to the multi-image generating apparatus 100 and the multivision 200.

The converters 300-1 to 300-9 are apparatuses for converting a standard of an image signal received from the multi-image generating apparatus 100 into another standard. In the multivision system shown in FIG. 2, the cable from which the image is output from the multi-image generating apparatus 100 is a 'UTP cable', whereas the cable from which the image is input to the multivision 200 is a 'HDMI cable'. Since both types are different, converters 300-1 to 300-9 are necessary.

The converters 300-1 to 300-9 convert the video signal received from the multi-image generating apparatus 100 through the UTP cable into the video signal of the HDMI standard, and transmit the video signal to the multivision 200 through the HDMI cable. Done.

Hereinafter, the multi-image generating apparatus 100 illustrated in FIGS. 1 and 2 will be described in detail with reference to FIG. 3. 3 is a block diagram of a multi-image generating apparatus 100 according to an embodiment of the present invention.

As shown in FIG. 3, the multi-image generating apparatus 100 includes an image providing unit 110, a memory 120, a controller 130, a switching unit 140, and connection slots 150-1 to 150-. 9) and image transmission modules 160-1 to 160-9.

The image provider 110 performs a function of acquiring images from various sources. The image providing unit 110 performing such a function includes an external interface-1 111, an external interface-2112, a storage 113, and a broadcast receiving unit 114.

The external interface-1 111 receives an image from an external device or an external network to obtain an image. The external interface-1 111 transmits the acquired image to the switching unit 140.

The external interface-2112 is also the same as the external interface-1111 in that it receives an image from an external device or an external network and acquires an image. However, the external interface-2112 differs from the external interface-1111 in that the external interface-2112 transfers the acquired image to the controller 130 instead of the switching unit 140.

As will be described later, the controller 130 decodes the input image and decompresses it. Therefore, the external interface-2 112 which transfers the acquired image to the controller 130 is used to obtain an image that needs decoding. In addition, the external interface-1 111 that directly transfers the acquired image to the switching unit 140 instead of the controller 130 is used to acquire an image that does not require decoding.

The storage unit 113 is a recording medium in which content is stored, and provides the stored content as an image. The image provided by the storage 113 is transmitted to the controller 130.

The broadcast receiving unit 114 provides a broadcast image received through the air or a cable as an image. The image provided by the broadcast receiver 114 is transmitted to the image transmission modules 160-1 through 160-9 mounted in the connection slots 150-1 through 150-9.

The controller 130 decodes an image provided by the external interface-2 112 and an image provided by the storage 113 to generate a decompressed image.

The switching unit 140 transmits an image in which 1) an image received from the external interface-1 111 and 2) an image received from the control unit 130 are mounted in the connection slots 150-1 to 150-9. A switching operation is performed to selectively output the modules 160-1 to 160-9.

The switching operation of the switching unit 140 is controlled by the control unit 130. That is, the image transmitted to the image transmission modules 160-1 to 160-9 among the images input from the switching unit 140 is determined by the controller 130, which will be described later.

The image transmission modules 160-1 to 160-9 are mounted in the connection slots 150-1 to 150-9. Specifically, 1) the image transmission module-1 (160-1) is mounted in the connection slot-1 (150-1), 2) the image transmission module-2 (160-2) in the connection slot-2 (150-2). ), 3) the image transmission module-3 (160-3) is installed in the connection slot-3 (150-3), ..., 9) the image transmission module in the connection slot-9 (150-9). -9 (160-9) is mounted.

The image transmission modules 160-1 to 160-9 extract a partial region from the broadcast image transmitted through the connection slots 150-1 to 150-9 to generate a split-image. The image transmission modules 160-1 to 160-9 transfer the generated split-image to the displays 200-1 to 200-9 constituting the multivision 200, respectively.

Meanwhile, the image transmission modules 160-1 to 160-9 display the images constituting the multivision 200 through the connection slots 150-1 to 150-9. (200-1 to 200-9), respectively.

Hereinafter, the image transmission modules 160-1 to 160-9 will be described in detail with reference to FIG. 4.
