Description

A REMOTE CONTROL METHOD FOR A MULTIPLE-SCREEN DISPLAY SYSTEM
The present invention relates to a method for controlling a multiple-screen display system formed to enable the source files to be displayed on a plurality of image display devices.
Image display devices display images on the screens thereof and the combination of a plurality of display devices in order to form a large screen display environment, i.e. a multiple-screen, is one of the functions achievable through the simultaneous operation of a plurality of individual image display devices. The term multiple-screen 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 multiple-screen image. The multiple-screens may typically be arranged in the form of 1x4, 2x2, 3x3, 4x4 or much larger screen formats.
The multiple-screens are preferred particularly due to the capability thereof to generate a large screen and to achieve greater pixel density per unit cost by changing the arrangement thereof, providing advantage due to manufacturing costs of single screens, and hence providing an unusual resolution when combined.
The multiple-screens are conventionally used in large public venues such as stadiums. The multiple-screens are required to be controlled together in order to be used as a single large screen display device. The multiple-screens are driven from multi-monitor video cards, but complex arrangements require special video processors capable to manage large multiple-screens. For this reason, generally, software-based multiple-screen controllers use computers and networking equipment.
In multiple-screen 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 distribution system and each image to be displayed on a single image display device is distributed by the central video distribution system. The image is accordingly divided by the central system.
Video transmission lines are established by connecting all the devices to the central video distribution system. Since the transmission lines must be changed manually when a system problem occurs in one of the image display devices or when the settings are needed to be changed, the device and the connections thereof are required to be disconnected and reconfigured.
The control of the central system can be realized remotely by means of various means, but additional procedures must be performed to control individual image display devices in the system. Said procedures are required to be performed by making the connections physically or by connecting the same to another control device.
In the state of the art Patent Document No. US2002116539, a method for remotely controlling a display system comprising a plurality of image display devices is disclosed. By controlling the image display devices remotely by means of the computers that are connected to the image display devices, the desired image settings can be changed.
In the state of the art Utility Model No. CN203225845, the data transfer between the image display devices by means of the input and output terminals in a multiple-screen application comprising a plurality of image display devices is disclosed.
The aim of the present invention is the realization of a method for controlling a multiple-screen display system formed to enable the source files to be displayed on a plurality of image display devices.
The multiple-screen display 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 multiple-screen display system can be widened as needed by providing data connection between the desired number of image display devices. 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 by means of at least one input and output connector, the same video or image content can be transmitted to a plurality of image display devices. The most common solution for controlling the image display devices remotely is to provide communication by means of the remote controller. In this method, by means of an infrared transmitter of the remote control and an infrared receiver of the image display device the data transfer is achieved by means of infrared signals. When the multiple-screen display systems are composed of a plurality of image display devices, using a separate infrared receiver in each device and controlling the devices by means of separate remote controls is not preferred due to high costs and inconvenience. In the present invention, by using a single infrared receiver, data can be transferred between the connected image display devices by means of the infrared input connector and the infrared output connector provided on each image display device. All the image display devices in the multiple-screen display system that are in infrared data communication with each other can be controlled by means of a remote control having an infrared transmitter. Thus, the multiple-screen display system can be remotely controlled without the need for an additional device or connection.
In an embodiment of the present invention, the multiple-screen display system is realized by arranging the image display devices one after the other in a vertical and horizontal plane. The physical position of each image display device on the plane is fixed by means of the hanger apparatuses that hold together the system and the transmission lines providing data transmission between the image display devices. Since the position of an image display device in the system is fixed, said position is used for defining the image display device in the multiple-screen display system. Said position is obtained by creating the address codes that specify the positions of the respective image display devices in the system by means of the control unit. The control unit may be integrated in one or more image display devices in the multiple-screen display system or may be composed of the control units and/or processors of each image display device. When a plurality of image display devices are connected to the control unit, the commands can be transmitted directly to the image display device the specific identity of which in the system is specified by defining the address code of said image display device.
In an embodiment of the present invention, the codes that are entered by means of the remote control are used to control the multiple-screen display system. The system is controlled by converting said codes to the commands by means of the algorithms defined in the control unit. When the commands received by means of the infrared receiver are transmitted to the control unit, all the image display devices process the same command and the system is controlled. By associating the codes transmitted to the control unit with the identifier address codes of the image display devices, the infrared signal to be sent by the remote control is enabled to be transmitted only to the image display device indicated in the address code. In order to achieve this transmission between the image display devices with no data transfer between the control units thereof, the infrared signal is transmitted to the respective device through the infrared connection lines. Thus, the infrared command received by the respective image display device is enabled to be also processed by the control unit of said image display device. The control unit can be provided as a central unit that is integrated in the multiple-screen display system and that is connected to all of the image display devices for controlling the operation of the image display devices and control units provided in each image display device for independently controlling the image display devices or can be provided as separate units in each image display device for controlling only the respective image display device. The control unit of the image display device that corresponds to the address code in the command entered is activated. The image display device with the control unit being activated is controlled by means of the remote control independently of other image display devices and thus, the settings of the desired screen can be changed. When the image settings of one of the image display devices differ from others or when the image display devices in the system malfunction, software updates or image setting changes can be performed on the malfunctioned image display device.
In an embodiment of the present invention, the address codes that define the positions of the image display devices are composed of number combinations. The code input to the control unit that has data connection to the infrared receiver is performed in two steps. In the first step of entering the code numerically by means of the remote control, the single image display device control is activated by defining a code to enable the remote control to be switched from controlling the multiple-screen display system to controlling a single image display device. Said code may be a different combination from the frequently used combinations such as the number of the channel that is desired to be watched. For example, a three digit code can be created for exiting the control of the entire system. After activating the single device control mode of the remote control, in the second step of code entering, the address code of the image display device to be controlled is entered. Since the address code can be defined in relation to the physical address of the image display device in the system, the address code can be created with consecutive numbers that are defined from left to right. Considering the number of image display devices generally used in the multiple-screen display systems, the address codes can be created as two or three digit numeric codes. Thus, by entering a five or six digit code, the switch from controlling the entire system to controlling the desired image display device can be easily made.
In an embodiment of the present invention, when the mode of controlling a single image display device is active in the multiple-screen display system, entering a predefined output code by means of the remote control deactivates the single image display device control mode and activates the mode of controlling the entire multiple-screen display system by means of the remote control. Thus, when the setting process in the individual image display devices are completed, the entire system can be controlled.
In another embodiment of the present invention, the multiple-screen display system comprises the image display devices each comprising a processor for the identification and generation of the particular screen portion of the received overall image or video content. The processor enables the commands received by the control unit to be executed. When the image display devices of the multiple-screen display system fail or when the image display devices are required to be operated so as to display different parts of video content of the total display area, the image display devices that can be controlled independently of each other are activated remotely and the process is enabled to transmit the image data only to the relevant image display devices.
By means of the present invention, the multiple-screen display systems that can be controlled by means of infrared data transfer can be controlled remotely in a more efficient manner. Furthermore, a multiple-screen display system that also enables the individual image display devices in the system to be controlled without the need for a different device connection is realized.
The multiple-screen display system realized in order to attain the aim of the present invention is illustrated in the attached figure, where:

The multiple-screen display system (1) comprises a plurality of image display devices (2) with a serial transmission line therebetween, wherein said image display devices (2) are connected to each other by means of the serial transmission line that transmits an image or video signal to the adjacent image display device (2) by means of at least one input connector and an output connector; an infrared input connector (3) for inputting infrared data and an infrared output connector (4) for outputting infrared data that are arranged in each image display device (2); a control unit (5) that controls the operation of the image display device (2), and an infrared receiver (6) with data connection to at least one image display device (2), enabling the commands to be transmitted to the control unit (5). By means of a remote control (K) that has an infrared transmitter and that sends commands to the control unit (5) by communicating with the infrared receiver (6), all the image display devices (2) connected to the system are enabled to be controlled remotely by means of the data connection along an infrared connection line (H) created between the consecutive image display devices (2) through the infrared input connector (3) and the infrared output connector (4) of each image display device (2). The command entered by means of the controls defined in the remote control (K) is transmitted to the infrared receiver (6) that communicates with the infrared transmitter of the remote control (K). The infrared receiver (6) enables the infrared signals to be transmitted to the image display devices (2) via the infrared connection line (H). When the command sent is aimed to be sent to a specific image display device (2) in the multiple-screen display system (1), the command selected on the remote control (K) is enabled to be sent to the respective image display device (2) through the infrared connection line (H) (Figure 1). Thus, the need for activating and controlling the image display device (2) separately by realizing cable connection with the image display device (2) or by means of an external computer is eliminated.
In an embodiment of the present invention, the multiple-screen display system (1) comprises the control unit (5) that creates the address codes, each indicating the positions of the image display devices (2) arranged on the horizontal and vertical axes in the system. The control unit (5) specifies the positions of the image display devices (2) in the multiple-screen display system (1) by assigning an address code. The specified address code is defined specifically for each image display device (2) and thus, the location of the respective image display device (2) in the multiple-screen display system (1) can be specifically determined.
In an embodiment of the present invention, in the multiple-screen display system (1), after the commands entered by means of the controls on the remote control (K) are associated with the address codes, the control unit (5) enables the infrared signal sent by the remote control (K) to be transmitted only to the image display device (2) with the specified address code. In this embodiment, the address codes of all the image display devices (2) in the multiple-screen display system (1) are defined in the control unit (5). By entering said codes, only the desired image display device (2) is controlled. The codes are entered by means of the controls on the remote control (K) with the infrared transmitter and transmitted from the infrared transmitter to the infrared receiver (6). The infrared receiver (6) enables the received command to be transmitted to all image display devices (2) by means of the infrared input-output connections between the image display device (2) with which the infrared receiver (6) is in data connection and the other image display devices (2). The control unit (5) of the image display device (2) that corresponds to the address code in the command entered is activated. The image display device (2) of which the control unit (5) is activated is controlled by means of the remote control (K) independently of other image display devices (2) and thus, the settings of the desired image display device (2) can be changed. Thus, an image display device (2) in the multiple-screen display system (1) is enabled to be controlled by means of the remote control (K) without the need for modifying the physical connections or using an external computer.
In an embodiment of the present invention, the address codes that define positions of the image display devices (2) are composed of number combinations. The code input to the control unit (5) that has data connection to the infrared receiver (6) is performed in two steps. In the first step of entering the code numerically by means of the remote control (K), the single image display device (2) control is activated by defining a code to enable the remote control (K) to be switched from controlling the multiple-screen display system (1) to controlling a single image display device (2). After activating the single device control mode of the remote control (K), the second step of code entering is performed by entering the address code of the image display device (2) to be controlled. Thus, when the need for changing a setting in any one of the image display devices (2) arises, the image display device (2) is enabled to be controlled easily by means of the remote control (K).
In an embodiment of the present invention, in the multiple-screen display system (1), when the mode of controlling an individual image display device (2) in the multiple-screen display system (1) is active, the control unit (5), with the entering of an exit code by means of the remote control (K), activates the control of the entire multiple-screen display system (1) by means of the remote control (K). Thus, when the setting processes in the individual image display devices (2) are completed, the entire multiple-screen display system (1) can be controlled again.
In an embodiment of the present invention, the multiple-screen display system (1) comprises the image display devices (2) each comprising a processor (7) for the identification and generation of the particular screen portion of the received overall image or video content. By enabling the individual image display devices (2) in the multiple-screen display system (1) to be controlled remotely, the video content to be viewed can be viewed on a viewing area with the desired width that is defined by activating the desired number of image display devices (2).
By means of the present invention, the remote control effectiveness of the multiple-screen display systems (1) that can be controlled by means of infrared data transfer is improved and a multiple-screen display system (1) wherein the individual image display devices (2) in the system are enabled to be controlled without the need for the connection of an additional device is realized.
