Additionally, the described embodiments are intended to be illustrative of some, but not all embodiments of the invention.
FIG. 1 illustrates a flow diagram of a method for controlling a tiled screen according to some embodiments of the present invention.
The method includes steps S1, S2, and S3:
s1, obtaining a display layout formed by display windows of all signal sources on a spliced screen.
The display content of each signal source is output to the spliced screen through the display control system, and the display position, the display window size, the stacking sequence and the like of each signal source on the screen may be different. The display layout in the present application is constituted by these display windows (i.e., the display layout is determined by the aforementioned display-window-related parameters). In some cases, the display windows may be generated by default so as not to overlap each other, and at this time, the display layout includes only display window size and position information.
And S2, analyzing the display layout and generating an operation interface according to the display layout analysis result.
The display layout contains information such as the size, position, etc. of the display window. By analyzing the display layout, the information such as the size and the position of the display window can be determined, and the size and the position of the operation interface to be generated can be determined accordingly according to the information.
For example, an operation interface can be generated to wrap each display window, so that the control position on the operation interface is located at the periphery or upper end of each display window or other blank positions.
The operation interface may include controls, for example, a control for selecting a certain display window, and a control for enlarging, reducing, or moving the display window.
And S3, outputting the operation interface to a splicing screen for a user to operate the operation interface.
In step S2, after the operation interface of step S3 is output to the tiled screen, the operation interface has a predetermined size and a predetermined relative position with respect to each display window. For example, it may be located at the periphery of each display window in the manner mentioned in step S2. According to some embodiments of the present invention, the operation interface may also be semi-transparently suspended above the signal source, or may be in a hidden mode until a user operates the operation interface, for example, a mouse moves to the hidden position.
According to some embodiments of the invention, the method may further comprise the step of: and responding to the operation of the user on the operation interface, and controlling the spliced screen.
The operation may be a user performing a touch operation on a control on the operation interface, or a user performing a keyboard operation and a mouse operation with reference to the operation interface.
When the spliced screen is a touch display screen and touch acts on an operation interface on the spliced screen, the input is converted into a touch action on the operation interface in the interaction end through a series of coordinate conversion. Since such coordinate conversion is well known to those skilled in the art, it will not be described herein.
The touch display screen includes a sensor capable of receiving a touch input and an imaging device capable of displaying an image, and includes, for example, an infrared light curtain type touch display screen, an infrared frame type touch display screen, and a capacitive sensing type touch display screen. For infrared light curtain type touch display screens, for example, those that include a portion that displays imagery (e.g., an LCD display), a portion that participates in capturing touch input (e.g., an infrared light curtain generating device and an infrared camera for generating an infrared light curtain on the screen surface); when a finger touches the surface of the screen, an infrared camera attached to the screen can capture a touch signal of the touch point of the finger, and the signal contains touch position information. In this application, the touch may also be a touch of a light beam to a screen or a touch off the screen.
And controlling the spliced screen, including controlling each display window on the spliced screen and controlling the signal source content in each display window on the spliced screen.
The controls may be user controls on the various source display windows, such as opening, closing, zooming in, zooming out, and moving the display windows. The control may also be a control of a certain signal source content, for example, marking the signal source content through a control on the operation interface. For the control aiming at each signal source, after receiving and judging the operation, the relevant instruction is sent to the corresponding signal source.
According to some embodiments of the present invention, by determining a position of a control or other information of the control, it may be determined whether an operation on an operation interface is an operation performed on each signal source or an operation performed on a display window, and if the operation is performed on the signal source, a related instruction is sent to the corresponding signal source, and if the operation is performed on the display window, the display window is controlled according to the operation instruction. In addition, the operation of the display window or the signal source can be determined through the information carried by the control.
According to some embodiments of the present invention, after the display layout is changed, the changed display layout may be obtained again, and the operation interface may be regenerated according to the display layout to adapt to the changed display layout.
According to some embodiments of the invention, the method further comprises the method steps involved in the following respective system embodiments.

The control center 7 controls the display layout of the signal sources 1 and 2 on the tiled screen 7, including controlling the decoding and displaying components to display a part of the signal sources 1 and 2 on the tiled screen, respectively, so that the signal sources 1 and 2 are finally displayed on the tiled screen in the display layout, as shown in the display content composed of the four small squares in the center of fig. 2.
The interactive terminal 6 is connected with the control center 7, and reads the display layout on the spliced screen in the control center 7, including reading the display position, the size of the display window, the stacking sequence and other information of each signal source on the screen. The interactive terminal 6 analyzes the display layout, and generates an operation interface according to the analysis result of the display layout.
According to some embodiments of the invention, an operation interface can be generated to wrap each display window, and the control positions on the operation interface are located at the periphery of each display window. The operator interface may be located at the dashed box location, as indicated by dashed box 66 in fig. 2.
The operation interface can comprise controls, such as a control for selecting a certain display window, a control for enlarging and reducing a certain display window.

According to some embodiments of the present invention, the operation interface (including operation interface distribution information, the same below) is output to the control center by the interactive end, and the control center divides the operation interface into the parts and sends the parts to the corresponding decoding and displaying components for displaying on the spliced screen. According to some embodiments of the present invention, the control center may determine, according to the distribution information of the operation interface on the mosaic screen and the correspondence between each decoding and displaying component and the sub-screen, the decoding and displaying component corresponding to each part constituting the operation interface, and divide the operation interface into the parts, and send the parts to the corresponding decoding and displaying components for displaying on the mosaic screen.
According to some embodiments of the present invention, the interactive terminal determines, according to the distribution information of the operation interface on the mosaic screen and the correspondence between each decoding and displaying component and the sub-screen, the decoding and displaying component corresponding to each part constituting the operation interface, and divides the operation interface into the parts, and sends the parts to the corresponding decoding and displaying components for displaying on the mosaic screen.
According to some embodiments of the present invention, the operation interface may be sent to a corresponding decoding display component in the form of operation interface generation data, and the decoding display component fuses the operation interface generation data with the signal source content and displays the fused signal on the spliced screen.
When the user performs input operation, including touch control (for example, the spliced screen 7 is a touch display screen), when the keyboard and the mouse operate controls on the operation interface, the interaction terminal receives the operation input, and performs corresponding response or controls the spliced screen.
Taking the touch input as an example, when the touch is applied to the operation interface on the spliced screen, the input is converted into a touch action on the operation interface in the interaction terminal through a series of coordinate conversions. Since such coordinate conversion is well known to those skilled in the art, it will not be described herein.
The touch display screen includes a sensor capable of receiving a touch input and an imaging device capable of displaying an image, and includes, for example, an infrared light curtain type touch display screen, an infrared frame type touch display screen, and a capacitive sensing type touch display screen. For infrared light curtain type touch display screens, for example, those that include a portion that displays imagery (e.g., an LCD display), a portion that participates in capturing touch input (e.g., an infrared light curtain generating device and an infrared camera for generating an infrared light curtain on the screen surface); when a finger touches the surface of the screen, an infrared camera attached to the screen can capture a touch signal of the touch point of the finger, and the signal contains touch position information. In this application, the touch may also be a touch of a light beam to a screen or a touch off the screen.
In the present application, it is right that the tiled screen is controlled, including the control of each display window on the tiled screen and the control of the signal source within each display window on the tiled screen.
The operation may be an operation performed by the user on each signal source display window, for example, opening, closing, enlarging, reducing, and moving the display window. And when the interaction end judges that the operation is directed at the display window, the corresponding operation instruction is sent to the control center, and the control center correspondingly controls the display window (or the display layout) to change.
The operation may also be an operation on the content of a certain signal source, for example, editing a word document in the signal source. And when the interaction end judges that the operation aims at each signal source, the interaction end sends the corresponding operation instruction to the corresponding signal source.
By determining the position of the control and the like, whether the operation on the operation interface is the operation performed on each signal source or the display window can be judged, if the operation is performed on the signal source, the relevant instruction is sent to the corresponding signal source, and if the operation is performed on the display window, the display window is controlled according to the operation instruction. In addition, the operation can be determined to be directed to the display window or the signal source through the information carried by the control.
According to some embodiments of the present invention, after the display layout is changed, the changed display layout is obtained in real time, and the operation interface is regenerated according to the display layout to adapt to a new display layout.
According to some embodiments of the present invention, the interactive terminal may pre-store the corresponding relationship between the sub-screens and the decoding and displaying components, for example, the sub-screens 61-64 correspond to the decoding and displaying components 111-444, respectively. The interactive terminal can also store decoding and displaying component information in advance, wherein the decoding and displaying component information comprises the decoding and displaying component address and the port number. The interactive terminal can determine the operation interface needs to be divided or coded into several parts correspondingly according to the stored information and the display layout, and the decoding and displaying component to which each part is sent. The corresponding relation and/or the address information can also be pre-stored in the control center according to the needs, or the interactive end sends the corresponding relation and/or the address to the control center according to the needs.
Moreover, as will be apparent to those skilled in the art after reading this context, the implementation details of the method embodiments described above with respect to fig. 1 are also applicable to the embodiment of fig. 2, and will not be described herein again.

The mosaic controller 8 controls the display layout of the signal sources 1 and 2 on the mosaic screen 7.
The interactive terminal 6 is connected with the splicing controller 8, and reads the display layout on the splicing screen in the splicing controller 8, including the display position of each signal source on the screen, the size of the display window, the stacking sequence and other information. And the interactive terminal 6 analyzes the display layout and generates an operation interface according to the analysis result of the display layout.
For example, an operation interface can be generated to wrap each display window, and the control positions on the operation interface are located at the periphery of each display window. The operator interface may be located at the dashed box location, as indicated by dashed box 66 in fig. 3.

When the user performs input operation, including touch control (for example, the spliced screen 7 is a touch display screen), when the keyboard and the mouse operate controls on the operation interface, the interaction terminal receives the touch input and performs corresponding response or controls the spliced screen.
Taking the touch input as an example, when the touch is applied to the operation interface on the spliced screen, the input is converted into a touch action on the operation interface in the interaction terminal through a series of coordinate conversions. Since such coordinate conversion is well known to those skilled in the art, it will not be described herein.
The operation may be an operation performed by the user on each signal source display window, for example, opening, closing, enlarging, reducing, and moving the display window. And when the interaction end judges that the operation aims at the display window, the corresponding operation instruction is sent to the splicing controller, and the splicing controller correspondingly controls the change of the display window.
The operation may also be an operation on the content of a certain signal source, for example, editing a word document in the signal source. And when the interaction end judges that the operation aims at each signal source, the interaction end sends the corresponding operation instruction to the corresponding signal source.
In the present application, it is right that the tiled screen is controlled, including the control of each display window on the tiled screen and the control of the signal source within each display window on the tiled screen.
By determining the position of the control and the like, whether the operation on the operation interface is the operation performed on each signal source or the display window can be judged, if the operation is performed on the signal source, the relevant instruction is sent to the corresponding signal source, and if the operation is performed on the display window, the display window is controlled according to the operation instruction. In addition, the operation of the display window or the signal source can be determined through the information carried by the control.
According to some embodiments of the present invention, after the display layout is changed, the interactive terminal obtains the changed display layout in real time, and regenerates the operation interface according to the display layout so as to adapt to the new display layout.
The mosaic controller 8 may also be other types of display control systems. For example, the display control system may also include a mosaic matrix.
