Description

A VIDEO WALL SYSTEM DATA TRANSFER METHOD
The present invention relates to a connection system for transferring data in a video wall display system which comprises a plurality of image display devices in connection with a control unit that processes source files to be displayed on a plurality of image display devices.
Image display devices present images on screens thereof, and combination of multi-display devices in order to form a large screen display environment called a video wall is one of the functions achievable through combination and simultaneous operation of a plurality of individual image display devices. The term video wall generally refers to the generation of a combined image from a single video input by means of a plurality of image display devices as a single video wall image. The video wall may typically be arranged in the form of 1x4, 2x2, 3x3, 4x4 or much larger screen formats.
Video walls are basically preferred due to their capability to generate a very large screen whose tile layout can be customized by which a greater screen area and greater pixel density per unit cost can be achieved, which is advantageous due to manufacturing costs of single screens, hence allowing an unusual resolution when combined.
Video walls are conventionally used in large public venues such as stadiums. Video walls can be driven from multi-monitor video cards, but complex arrangements require special video processors capable to manage large video walls. For this reason, generally, software-based video wall controllers use computers and networking equipment.
In video wall applications, each image display device of the system requires individual cable installation for effecting data communication with a central computer.
The video distribution is possible through different methods. One of the methods includes a central video distributor system and each image to be displayed on a single image display device is distributed by the central video distributor system. The image is accordingly divided by the central system. Thus, although independent, the screens can be joined together and can display images as a whole. In said systems composed of a plurality of image display devices, it is advantageous to manage the control from a single point. In structures composed of independent image display devices, the device control is carried out by means of communication with one infrared receiver. However, in said systems composed of a plurality of image display devices, providing an infrared receiver in each device increases costs and the distance between the receiver and transmitter causes inconvenience while the need for controlling the receivers with different devices arises. Moreover, the difficulty of installing and positioning the infrared receiver causes technical service problems.
In the state of the art Patent Document No. EP2328073, a video wall system is disclosed, which includes a plurality of display devices, each of the display devices including a pair of input and output connectors comprising an input connector connected to a first neighboring display device among the plurality of display devices to input an image signal from the first neighboring display device, and an output connector connected to a second neighboring display device to output the input video signal; a signal processor which processes the input video signal; and a display which displays an image based on the processed video signal.
In the state of the art Patent Document No. US 2014119675, a method in a video wall system comprising a plurality of image display devices is disclosed, for providing the data exchange between each image display device and the other image display devices in the system by means of a plurality of connections.
The present invention provides a system and method for providing serial connection between adjacent image display devices of a video wall system such that a plurality of image display devices are in connection with each other through a serial line transferring the video signal to the neighboring image display device.
The video wall system realized in order to attain the aim of the present invention, explicated in the first claim and respective claims thereof comprises a plurality of image display devices connected with a serial transmission line. The display area of the video wall system can be widened as needed by providing data connection between the desired number of image display devices. By processing the command sent to the control units of the image display devices, the desired image content can be viewed. By connecting a plurality of image display devices that are connected to each other via the serial video transmission line that transfers the image or video signal to the neighboring image display device, the same video or image content can be transmitted to a plurality of image display devices. By activating at least one infrared receiver eye in the video wall system by sending an infrared command to the system, the infrared data is delivered to an image display device in the system by means of a cable connection and by means of the infrared input connector of the image display device. The same infrared data is transmitted to the input connector of another image display device by means of the infrared output connector of the image display device to which the data is transmitted, and thus, the infrared data is transferred between the image display devices in the video wall system. Thus, by transmitting infrared data to the entire video wall system using a single infrared receiver eye, cost advantage and ease of control are provided.
In an embodiment of the present invention, the image display devices in the video wall system comprise at least one infrared input connector and at least one infrared output connector. By means of the connection lines formed by the infrared input connector and the infrared output connector on each image display device, the infrared data can be transferred between all the image display devices in the system. Thanks to the connection line, the need for connecting the infrared output connector of the image display device which receives the infrared data last to another image display device is eliminated.
In an embodiment of the present invention, a first image display device defined in the video wall system receives the infrared data from the infrared receiver eye by means of a first infrared input connector provided on the device. Said infrared data is processed and converted to a command in the control unit of the image display device to which the data is transmitted, thus actuating the processing process in the control unit. Moreover, a connection line is provided, that enables the infrared data to be transmitted to a second input connector on a second image display device by means of a first output connector on the first image display device. Thus, the infrared data is enabled to be simultaneously transmitted to the image display devices through the connection line.
In an embodiment of the present invention, direct data transmission between the infrared input connector and the infrared output connector provided on the image display devices in the video wall system is provided. There is data flow between the infrared input connector and the infrared output connector and the control unit of the image display device. When the infrared data received by the infrared input connected is transmitted to the control unit, the infrared data is processed and converted to a command, enabling the image display device to be operated according to said command. A time period elapses for the processing of the infrared data in the control unit. By means of this embodiment, the infrared data is transmitted in parallel so as to directly pass between the infrared input connector and the infrared output connector without being processed in the control unit. The infrared data received from the infrared input connector can be directly transmitted to the infrared output connector with a short circuit on the printed circuit board.  Since the infrared data can be directly transmitted between the image display devices without being processed, data transmission can be realized in a short time without losing time for converting the infrared data to command.
In another embodiment of the present invention, a method for operating a video wall system comprising a certain number of image display devices is realized, comprising the steps of transmitting the relevant command to the control unit by means of an infrared input connector on a first image display device by cable after receiving an infrared signal by an infrared receiver eye, transmitting the same signal to a second image display device adjacent to the first image display device through an infrared output connector, transmitting the infrared data received by the second infrared input connector of the second image display device to a third image display device adjacent to the second image display device by means of the second output connector, and successively transmitting the infrared signal, that is transmitted to a last image display device by means of the connection line composed of infrared input connectors and infrared output connectors, along a connection ending with the transmitting of the infrared data to the control unit of the last image display device. Thus, by using a single infrared receiver eye, a video wall system is realized, wherein the production costs are decreased and the simultaneous control efficiency from a single point is increased.
By means of the present invention, a video wall system is realized, wherein the command transmission efficiency between the image display devices is improved and cost advantage is provided.

The video wall system (1) operates according to a method of serial transmission of the video content to obtain an overall image in a much larger size that a single display device (2) cannot display by way of dividing the main image into a plurality of image portions for display on separate image display devices (2). The image display devices (2) may be connected to each other to establish a video transmission line through respective pairs of input and output connectors. Each image display device (2) within the video wall system (1) is defined to display a certain dedicated portion of the video content and accordingly divides the video content so as to generate a specially adapted portion of the video content corresponding to the specific screen area of the overall combined screen size depending on the number of image display devices (2) on the vertical and horizontal axes. Each image display device (2) comprises a control unit (3) that controls the operation thereof and that is in data communication with the other image display devices (2). The video wall system (1) comprises an infrared receiver eye (4) that is in data connection with at least one image display device (2) and that can transmit data to the control unit (3). Infrared data transmission between the image display devices (2) can be realized by means of a connection line (7) that can transmit the command received from a single image display device (2) with infrared data transmission by means of an infrared input connector (5) and an infrared output connector (6) that work so as to form a physical serial data transmission line to the infrared input connector (5) of another image display device (2) with data connection, the connection line (7) further providing the data transfer by transmitting the data received by the infrared input connector (5) through the infrared output connector (6) to the infrared input connector (5) of another image display device (2). Thus, by using a single infrared receiver eye (4), a video wall system (1) is realized, wherein infrared data transmission is improved and cost and assembly advantage is provided.
In an embodiment of the present invention, the video wall system (1) comprises the image display devices (2), each having at least one infrared input connector (5) and at least one infrared output connector (6). Thus, the infrared data received by an image display device (2) by means of the infrared input connector (5) can be transferred to another image display device (2) by means of the infrared output connector (6) on the former image display device (2).
In an embodiment of the present invention, the video wall system (1) comprises the connection line (7) that enables the data received by a first infrared input connector (105) provided on a first image display device (102) in the system (1) to be transmitted to the infrared input connector (205) on a second image display device (202) by means of a first infrared output connector (106) provided on the first image display device (102). Thus, infrared data transmission can be simultaneously realized between successive image display devices (2) (Figure 3).
In an embodiment of the present invention, the video wall system (1) comprises the control unit (3) that provides direct data transmission between the infrared input connector (5) and the infrared output connector (6) provided on an image display device (2). The infrared data transmitted to the infrared input connector (5) can be transferred in two ways. The infrared data received is transmitted to the control unit (3) and processed so as to be converted to a command, thus enabling the image display device (2) to carry out the relevant function. The same infrared data can be directly transmitted from the infrared input connector (5) to the infrared output connector (6) without being processed. Thus, the time period required for infrared data transmission is shortened, and infrared data can be shared with all the image display devices (2).
In another embodiment of the present invention, a method for operating a video wall system (1) comprising a certain number of image display devices (102, 202, 302 ...) is realized, comprising the steps of (a) transmitting the relevant command to the control unit (3) by means of an input connector (105) on a first image display device (102) by cable after receiving an infrared signal by an infrared receiver eye (4), transmitting the same signal to a second image display device (202) adjacent to the first image display device (102) through an output connector (106), transmitting the infrared data received by the second input connector (205) of the second image display device (202) to a third image display device (302) adjacent to the second image display device (202) by means of the second output connector (206), and successively transmitting the infrared signal, that is transmitted to a last image display device (N02) by means of the connection line (7) composed of infrared input connectors (305) and infrared output connectors (306), along a connection ending with the transmitting of the infrared data to the control unit (3) of the last image display device (N02). In the video wall system (1), generally a plurality of image display devices (2) are successively arranged so as to form a square or a rectangle. If the number of total image display devices (2) in the video wall system (1) is defined as N, the last image display device connected to the connection line (7) is the Nth device. As an example to said arrangements, when a 3x3 arrangement is planned, the video wall system (1) comprises a total of 9 image display devices (2). In this case N=9, and the last image display device (902) in the video wall system (1) is the 9th device. The infrared output connector (906) of the last image display device (902) in the example is not connected to any image display device (2). Thus, by means of a single infrared receiver eye (4), a video wall system (1) is realized, wherein a desired number of image display devices (2) are connected to each other so as to receive infrared data, thus improving the control efficiency and decreasing costs.
By means of the present invention, a video wall system (1) is realized, wherein the infrared data transmission efficiency between the image display devices (2) is improved and production advantage is provided by using a single infrared receiver eye (4).
