Definitions

  • the present invention relates to a system and method for operating a video wall display system which comprises a plurality of display devices in connection with a control unit that process 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 are driven from multi-monitor video cards, but complex arrangements require special video processors capable to manage large video walls. Software based video wall controllers however use PCs and networking equipment.
  • 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. Cable installation must be carried out during the system setup and in case a need for repair emerges, the operation often requires complete maintenance of the overall installation.
  • Video transmission lines are established by connection of all devices to the central video distributor system. Video transfer is typically effectuated by HDMI or DVI-D connections.
  • Another method uses serial connection between separate image display devices through which transfer of the whole video content to an adjacent image display device is performed. Appropriate divisioning of the video content by individual image display devices is ensured by a processor of each image display device. In the case an error occurs in the cable installation of one of the image display devices, it effects video transfer to the adjacent image display device in the manner that no image can be transmitted further along, from the defected device on along the serial video transmission line of the video wall.
  • EP2328073 discloses a video wall system 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.
  • 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 present invention provides a video wall system and a method for operating the same in the manner that a plurality of image display devices connected to each other can be reorganized to create a new display web in response to interruption of video signal through a video signal transmission line between the image display devices.
  • the present invention further provides interchangeable input and output connectors functioning through a bidirectional or multi-directional switching system determining the transmission direction of the signals between neighboring image display devices within the video wall system.
  • the present invention therefore provides a system and method for operating video wall systems as provided by the characterizing features defined in Claim 1.
  • Primary object of the present invention is hence to provide a system and method for operating a video wall system in which reorganization of active image display devices is possible in response to an error status in an image display device.
  • the present invention proposes a video wall system in which a control station communicating with at least one image display device unidirectionally effectuates video transfer.
  • the control station dynamically determines a certain number of image display devices creating a generally rectangular alternative web of active screen area excluding the dysfunctional image display device.
  • the image display devices in the active screen area then display an accordingly adapted version of the complete image or video content.
  • Input and output connectors of individual image display devices are interchangeably programmable to dynamically change the transmission direction of the video signal between neighboring image display devices so that a reorganized web of active image display devices can be created. If at least one dysfunctioning image display device is spotted in a location other than the uppermost or lowermost row of the matrix-like web of image display devices, the control station additionally simultaneously initiates a second video transmission line in the reverse direction to the first video transmission line.
  • Fig. 1 demonstrates a schematic view of a 3x3 video wall system with input connectors.
  • Fig. 2 demonstrates a schematic view of a 3x3 video wall system with input and output connectors and a serial video transmission line.
  • Fig. 3 demonstrates a schematic view of a 3x3 video wall system with input and output connectors and while an error status in an image display device interrupts the serial video transmission line in the video wall system.
  • Fig. 4 demonstrates a schematic view of a 3x3 video wall system with programmable input and output connectors according to the present invention.
  • Fig. 5 demonstrates a schematic view of a 3x3 video wall system with programmable input and output connectors receiving the video signal in a second direction according to the present invention.
  • Fig. 6 demonstrates a schematic view of a 3x3 video wall system with each image display device having a pair of input and output connectors capable of receiving the video signal bidirectionally according to the present invention.
  • Fig. 7 demonstrates a schematic view of a 3x3 video wall system with each display device having a pair of input and output connectors receiving the video signal in a second direction according to the present invention.
  • Fig. 8 demonstrates a schematic view of a 3x3 video wall system with each display device having a pair of input and output connectors while an error status in an image display device interrupts the video transmission line in the video wall system and upon which the video signal is bidirectionally receivable according to the present invention.
  • Fig. 9a demonstrates a schematic view of a 3x3 video wall system with fully functional image display devices.
  • Fig. 9b demonstrates a schematic view of a 3x3 video wall system with a dysfunctional image display device such that a reorganized web of image display devices is configured to display an image or video content in a complete manner according to the present invention.
  • the present invention proposes a video wall system with a multitude of image display devices, each device comprising at least one input and output connector.
  • a control station in data communication with each image display device of the video wall system controls the operation of the video wall system as delineated below.
  • the control station effectuates transferring of the video content through a video input of the video wall system to a plurality of image display devices, the latter together forming a combined very large screen in the form of a generally rectangular web.
  • Each of the combined image display devices then generates and displays a certain dedicated portion of the video content so that the video content can be displayed on a combined large screen.
  • Each of the image display devices comprises a processor for identification and generation of the dedicated portion of the complete image or video content.
  • the image display devices receive and then transmit the image or video content to a neighboring and generally adjacent target image display device.
  • the video wall system therefore operates according to a method of serial transmission of the image or video content to obtain an overall image in a much larger size that a single display device cannot display, by way of dividing the main image into a plurality of image portions for display on separate image display devices.
  • the image display devices may be connected to each other to establish a video transmission line through respective pairs of input and output connectors.
  • the connectors may typically be in the form of high definition multimedia interface (HDMI) or DVI-D type connectors.
  • HDMI high definition multimedia interface
  • DVI-D DVI-D type connectors.
  • the input and output connectors provide cable connections allowing serial connection of multiple display devices through the video transmission line.
  • the control station of the video wall system is typically a computer system with video stream processing capabilities.
  • the control station transfers the source images to a first image display device to be transmitted from the first image display device to one of the immediately neighboring display devices through the input and output connectors on the video transmission line.
  • two neighboring image display devices can be placed vertically, horizontally or otherwise with respect to each other so that a generally rectangular shape large screen is obtainable.
  • Each image display device within the video wall system is configured to display a certain dedicated portion of the image or video content and accordingly divides the image or video content so as to generate a specially adapted portion thereof corresponding to the specific screen area of the overall combined screen size depending on the number of image display devices on the vertical and horizontal axes.
  • each image display device dynamically processes the received image or video content to identify its particular screen portion of the combined screen and transfer the overall image or video content to an adjacent target image display device.
  • the overall image transferred to the targeted image display device is then processed again by the latter to identify its particular screen portion.
  • the method of operation of the video wall system with a certain number of image display devices involves receiving of the video signal by a first display device and displaying of a particular portion thereof as a processed video signal while at the same time transferring of the complete video signal to a neighboring second image display device.
  • the video signal is then delivered by the second display device to a third display device and subsequent transfer of the image or video content through the video transmission line continues until a final image display device receives the video content and generates its particular screen portion.
  • the present invention ensures that the video transmission line being interrupted by a dysfunctional unit effects the operation of the video wall system in a minimized amount.
  • the video signal transfer to the neighboring target image display devices along the video transmission line will be affected resulting with the visualization of only a certain portion of the overall image. In other words, no image can be displayed on subsequent image display devices starting from the defected device as demonstrated Fig. 3.
  • the control station which has at least two video signal transmission connections with a first and second non-neighboring image display devices at both ends of the video transmission line of the video wall system simultaneously additionally initiates, if necessary, video signal transmission through a second video transmission line in the reverse direction so that image display devices subsequent to the defected image display device on the first video transmission line can receive the video signal through the second video transmission line.
  • the control station dynamically initiates video transmission in an altered second signal input direction in addition to the original video transmission line depending on the circumstances.
  • each input and output connector can be interchangeably used such that an input connector can also be used as an output connector (Fig. 4 or 5).
  • the interchangeably usable input and output connectors can be programmed as input or output connectors by the respective image display devices upon a directional switching signal from the control station. Interchangeable reprogramming of the input and output connectors allows bidirectional image transfer between the image display devices. In other words, in the event that an error status for a certain image display device is observed by the control station, the source image is delivered to the final image display device in a first video transmission line and a second video transmission line in which the latter image display device is the first device is simultaneously created.
  • the control station of the present invention reorganizes a new web format based on the position of the defected image display device so as to generate a transformed version of the complete image or video content.
  • a new web of image display devices forming a generally rectangular screen area is automatically configured by the control station and the respective information is communicated to all functioning image display devices.
  • the reorganized image or video area is configured to create an area as large as possible to display the full image or video content.
  • the control station may create a web format in the manner that the length and width ratio of the video wall web is changed or remains unchanged.
  • a videowall system having a 3x3 web with a defected image display device may be provided with a new web configuration of display devices having a 3x2 web of functional image display devices so as to obtain the largest possible screen area.
  • the system may alternatively offer a 2x2 web screen area in the case the length and width ratio of the video wall web is kept constant.
  • the control station transfers the source image or video content simultaneously to a first and second image display device according to the new web arrangement so that each and every image display device obtains the full image or video content and identifies its particular screen portion of the combined screen according to the reorganized web.
  • the image display devices may become inactive due to the reorganization. Such functional but inactive image display devices may optionally present alone the full image or video content with a corresponding resolution (Fig 9b). It is also to be noted that the control station may not initiate the second video transmission line if the defected image display device is located on an uppermost or lowermost row of the web or matrix, in which case a single unidirectional video transmission line is sufficient for effecting creation of the largest possible image or video display area.
  • the present invention ensures that the video transmission line being interrupted by a dysfunctional unit effects the operation of the video wall system in a minimized amount.
  • the control station according to the present invention which may have two video signal transmission connections with a first and second image display device of the video wall system may initiate video signal transmission optionally simultaneously through a second video transmission line so that image display devices following the defected image display device along the first video transmission line can receive the video signal via the second video transmission line.
  • the image display devices involved in the reorganized active web of image display devices are communicated such information through the data communication links between the control station and each image display device. Functioning but inactive devices in the reorganized web can optionally display alone the complete image or video content.
  • the control station may dynamically initiate video transmission in an altered second signal input direction in addition to the original video transmission line and determines those image display devices configured to create a new web of active screen area.
