Figure 3 - flow of remote control method in one embodiment of the invention is the diagram.

The parts in the figure are numbered one by one. the responses are given below. 1, Video wall 2. Imaging device 3. Indicator The video wall (l) consists of two connected or includes more display devices (2). Each display device (2), a control unit for controlling the respective display device (2) contains. Video wall (1), a pointing device, especially in Video wall (l) move within the video wall (1) according to the movements of the displayed and pointing device. It is controlled by a pointer (3) that is moved. User or operator moves the pointing device, and accordingly, on the video wall (1), pointer (3), eg pressing one or more keys on the pointing device or predefined motions with their opening or pointing Device This allows selection or command input via the Pointing Device. It provides a user interface that allows

Multiple display devices (2) forming the video wall (1) in matrix form can be placed. Imaging devices (2) have cascading connection can happen. In this case, the display devices (2) are connected to each other by a serial control connected via line. In this configuration, the pointing device is serial only. in direct communication with the first display device (2) in the control line can happen. sent from the pointing device and in the first display device (2) control signals received by the receiver (eg infrared receiver) (eg. infrared light) along the control line through the first display device (2) transmitted to other display device/devices (2).

In the preferred embodiment of the invention, the video wall (1) uses a selective control mode. is operating. Selective control mode means that a display device (2) stand-alone control, according to at least some of the commands transmitted from the ensures that. In selective control mode, each control unit determines the current position of the beacon (3) within the video wall (1) and According to the current position of the pointer (3), the commands from the pointing device are optional. It controls the relevant display device (2) to respond as For example, when the pointer (3) is on a particular display device (2), the user sends a command to the video wall (1) by pressing a button on the pointing device, subject to the command of the relevant display device (2) and the remaining display devices (2). responds in a different way.

In one embodiment of the invention, this means that the remaining imaging devices (2), i.e. all other points except the pointer (3) on the video wall (1). display devices (2) not responding to at least some of the commands and the display device (2) on which the pointer (3) is performed by responding to commands. To this end, each control When the video wall (l) is in selective control mode, the pointer (3) mark if its location is within the viewing area of said display device (2) by responding to commands from the device and saying the current position of the pointer (3). if the subject is outside the viewing area of the imaging device (2), this a related display device, ignoring at least some of its commands. (2) is checking.

A 3x3 video wall (1) can be taken as an example. Pointer (3) upper left at the display device (2) the user presses a menu key on a pointing device. When pressed, only the display Device (2) in question will display the menu. A device that responds to the command and allows the settings of the device (2) to be controlled. displays the menu (M). Even if they receive the same command from the pointing device, the remaining eight display devices (2), command response by their control units It is operated in such a way that it will not display the menus. (Fig. la). Same pointing device (2) when pointer (3) is in center right display device run the same way, this time the command will be displayed on the middle right display device (2) performed by the remaining eight display devices (2) is counted (Fig. lb).

Selective control allows some or all of the commands received from the pointing device. applicable. In the latter case, each associated with a display device (2) the controller defines the command as part of the selective control. checks that it is not defined and only if this is the case, the pointer (3) provided that said display device (2) is not positioned above it, it controls the relevant display device (2) to ignore the command.

Manufacturer, user or operator of the video wall (1) in selective mode can set specific commands or certain types of commands to be executed.

These commands from the pointing device can be made any time the command is transmitted. All display where the pointer (3) is not in the display area above will be ignored by the devices (2). Commands or command to ignore types, i.e. commands included in selective mode, may also be additionally or alternatively can also be set via an operating mode of the video wall (1).

In one embodiment of the invention, commands executed in selective mode, voice and/or Contains commands for display settings. This way, you can only use the pointer. (3) by bringing it into the viewing area of a desired imaging device (2), audio and/or video settings of the single display device (2) (1) interfering with the settings of other display devices (2) can be adjusted.

The video wall (l) is also in a composite control mode in addition to the selective mode. can be operated. In unified control mode, all the video wall (1) display devices (2) are controlled simultaneously. In other words, all display devices (2) respond to control commands received from the pointing device gives. The video wall (1) responds to a specific command received from the pointing device. switching between selective control mode and unified control mode can do. The user or operator, for example, on the pointing device by opening or pressing an assigned key, or at a predetermined By pressing the key combination, you can activate the selective control mode or can be deactivated.

A video wall (1) or a video wall (1) described above pointing device that allows to control a video to achieve the purpose of the invention wall system. Pointing device according to different keys pressed on it predefined infrared light patterns, for example, according to the RC-5 protocol. It can be a transmitting remote control. The pointing device is a three-dimensional gyroscope and can be used as an air mouse. displayed on the video wall (l) and the pointer (3), a standard cursor or Video wall (1) in any form that represents a point in the viewing area can be a marker.

The method of remote control of the Video wall (l) in question, the pointing device the commands it generates to each of the display devices (2) on the video wall (l). transmit step (101) and the pointer (3) in question is currently displayed. it includes the step (102) of determining the imaging device (2).

The method also allows any of the remaining display devices (2), i.e. the pointer (3), to be display devices (2), on which they are not positioned at one time, Controlling it to respond selectively to the commands received from the device In one embodiment of the invention, the identified display device (2) is from the pointing device. While being controlled to respond to received commands, the Video wall (1) one or more of the remaining display devices (2) are received from the pointing device. It is controlled to ignore at least some of the commands.

The method has various number and location of imaging devices (2). to make it work smoothly on different video walls (1), layout information during or after setting up a video wall system It can be transmitted (110) to the display devices (2) on the video wall (1). This For this purpose, in an optional first step, the placement of the video wall (l) and the horizontal and vertical The number of display devices (2) in each direction is equal to the number of display devices (2) in each unique identification numbers are transmitted to one and to the display devices (2). is appointed. In this way, each display device (2) Video wall (1) matrix an active area for a pointing device by calculating its relative position within can determine. The active area is within the video wall (1) image of the pointer (3) It defines the area where it can move. The active area is set on each video wall (1). taking into account the resolution information of a display device standard] can be superimposed, in this way, the coordinate data received from the pointing device, processing of the video wall (1) according to its dimensions and the beacon (3) accordingly It is provided to be displayed and moved in this way (120).

On video walls (l) of different layout or size, the pointing device moving a certain amount in the direction of the pointer (3) on the video wall (1) will cause it to travel different distances and move at different speeds. For example, moving the pointing device by a certain amount causes the pointer to become a 1x2 the same amount of movement in the horizontal direction on the video wall (1) and a 2x2 video wall (1) will cause it. However, in response to the same movement of the pointing device vertical movement of pointer (3) in vertical direction in 2x2 layout relative to 1x2 layout will be twice as high (Figure Za and Figure 2b). Similarly, the pointing device moves causing the pointer (3) to move 2 pixels in a 2x2 layout, The same amount of movement of the pointing device makes the pointer (3) 3 pixels in a 3x3 layout will cause it to move (Figure 2b and Figure 2c).

Transmission of location information to imaging devices (2) (110) and above the active pointer (3) through the normalization process as briefly described By defining the area (120), the method in the claims, size and location It can be applied to any video wall structure regardless of

In another optional step of the method in the claims, you can set the video wall (1) to optional It is determined whether it is in control mode (130). In imaging devices (2) the control units located, for example, the signaling of the signals received from the pointing device. Indicates that a selective control mode is enabled on the device. by checking periodically that the selective control mode can determine its status. From each display device (2) pointing device receives the transmitted commands (101). Imaging devices (2) also control the current position of the pointer (3) on the Video wall (1). is following. Each display device (2) is constantly showing that the pointer (3) is present. coordinates of the display device (2) in the display area. checks whether it corresponds (102). specific display device (2) that the video wall (1) is in selective control mode and that the pointer (3) is in the corresponding received from the pointing device when it determines that it is within the viewing area. at least some of the commands are only available for the specific display Device in question. (2) is conducted by (103). On the other hand, when the video wall (l) is determined to be in unified control mode, Commands received from the pointing device are sent by all display devices (2). carried out (140).

Unless otherwise specified, display devices (2), control units and beacon mentioned features of the device, possible additional or It has been designed with alternative steps in mind. Each of these steps and combinations compatible with the main application, video wall (1) remote control envisaged as applications of the method.

Subject of the invention Video wall (1), Video wall system and related remote control from display devices (2) within a video wall (1) using the any desired stand-alone control in an easy and user-friendly way can be achieved. Commands entered from a pointing device such as a remote control at least some of it, only the specific display to which the pointing device is pointing is carried out by the device (2). This way, on a video wall (1) display devices (2) to other display devices (2) on the video wall (1) can be controlled by itself without intervention.
