Wherein a plurality of displays included in the display group can be combined and spliced into a spliced display wall, the form of the spliced display wall can be seen in fig. 2A, wherein the image resolution of the input signal can be understood as the size of each frame of image in the input signal. In this case, a display described in this embodiment may refer to any display area on the tiled display wall, such as the display area 201 in fig. 2A, which may be tiled by different displays, that is, the display area 201 may be tiled by a part of the display area of each of the two displays. In the embodiments described below, a portion of the input signal may be displayed only on one or more display areas of the tiled display wall. Alternatively, the displays in the display group may be independent, and the displays in the display group may be arranged at different physical positions, as shown in fig. 2B, where fig. 2B shows an arrangement of the displays, where the display 203 is a vertical display and the display 205 is a horizontal display.

The following describes embodiments of methods provided by embodiments of the present application, in conjunction with the above-described system.
Referring to fig. 3, fig. 3 is a schematic flow chart of a signal control method according to an embodiment of the present application. The method is applied to the signal control equipment, wherein the signal control equipment can comprise a control device and a processing device. The method shown in fig. 3 is described by steps executed by the control device and the processing device in the embodiment of the present application. As shown in fig. 3, the method includes at least the following steps.
Step S301, the processing device collects input signals from a signal source and sends the collected image resolution of the input signals to the control device.
In some possible implementations, the processing device may collect an input signal from a signal source, where the input signal may be a video signal or an image signal, and the video signal includes a plurality of frames of image signals. The signal source may transmit one or more frames of image signals in the video signal at a time, and the embodiments of the present application are not limited in particular. The processing device may determine the image resolution of the input signal after receiving the input signal, where the image resolution of the input signal refers to the image size of each frame of image signal in the input signal, and may also be understood as the image resolution of each frame of image signal. The image resolution of each frame of image signal in the input signal may be the same or different. The processing means may be capable of transmitting the determined image resolution of the input signal to the control means, the image resolution of the input signal being a reference for the control means to generate the configuration information.
Meanwhile, the processing device may store the received input signal into a memory configured in the signal control device in a row-by-row or column-by-column manner, where the memory may be a buffer, a memory, a hard disk, or the like, and the embodiment of the present application is not particularly limited herein. The processing means writes the input signals in a row-by-row manner, which can also be understood as writing the input signals in a horizontal manner, in which manner the input signals or parts of the input signals can be displayed for a horizontal display (e.g. the display 205 in fig. 2); the processing means writes the input signals in a column-by-column manner, which may also be understood as writing the input signals in a vertical manner, in which case the input signals or parts of the input signals can be displayed suitable for a vertical display, such as the display 203 in fig. 2. Before that, the processing means can also perform color space format conversion on the input signal so as to facilitate the signal control device to transmit the input signal in the converted format.
In step S302, the control device receives the image resolution of the input signal.
Step S303, the control device receives first configuration information of the peer device for the input signal.
In some possible implementations, the control device may receive an image resolution of an input signal, and the control device may also receive first configuration information of the peer device for the input signal. In the embodiment of the present application, the control device does not specifically limit the receiving order of the information. That is, the execution sequence of step S302 and step S303 is not particularly limited.
Specifically, the first configuration information for the input signal sent by the peer device to the signal control device carries the signal parameter information. The control device can receive the first configuration information through a communication interface configured in the signal control device and the opposite terminal device. The control device may receive the first configuration information sent by the peer device in real time, or may receive the first configuration information sent by the peer device after sending a request for the first configuration information to the peer device, where this embodiment of the present application is not specifically limited.
In step S304, the control device determines second configuration information for the output signal according to the first configuration information and the image resolution of the input signal, and sends the second configuration information to the processing device.
In some possible implementations, the control device may determine second configuration information for the output signal according to the first configuration information and an image resolution of the input signal, and send the configuration information to the processing device. Specifically, the first configuration information may carry a signal identifier of a corresponding input signal to indicate the input signal corresponding to the first configuration information, and the first configuration information may include signal parameter information for determining an output signal.
One implementation manner is that the first configuration information includes coordinate information of one or more reference pixels and indication information based on the pixels, and the coordinate information of the reference pixels is the same as a reference coordinate axis on which the coordinate information of each pixel of the input signal is based. The specific position of one or more reference pixel points in the input signal can be determined through the coordinate information of the one or more reference pixel points. For example, as shown in fig. 4, each pixel point in the input signal establishes coordinate information based on an x-y two-dimensional coordinate axis, assuming that the first pixel point of the input signal is a pixel point P0 representing an upper left corner of the image, and the coordinate information of the pixel point P0 can be defined as (0, 0), the first configuration information may carry the coordinate information of the pixel points P1 to P4, and the specific positions of the pixel points P1 to P4 in the input signal can be respectively determined according to the coordinate information of P1 to P4, and when the specific positions of the pixel points P1 to P4 are determined, the output resolution of the output signal can be determined according to indication information based on the pixel points, for example, as shown in fig. 4, the first configuration information is further used to indicate that the pixel points P1 to P4 are four vertices of the image represented by the output signal, and the shape of the image represented by the output signal is rectangular, the output resolution of the output signal can be determined according to the coordinates of the pixel points P1 to P4 as (y 1-y 0) (x-y-1-x 0) (x-1-1) ) Where (y 1-y 0) represents the number of row pixels and (x 1-x 0) represents the number of column pixels, the output resolution of the output signal may also be understood as the size of the output signal, or as the size of the image represented by the output signal.
Another implementation manner is that the first configuration information includes coordinate information of a reference pixel point, output resolution information of an output signal, and the like. The reference pixel included in the first configuration information may be coordinate information of a starting pixel of the output signal, for example, as shown in fig. 4, a pixel P1 is used as the starting pixel of the output signal, and the first configuration information may only carry coordinate information of a pixel P1; the first configuration information may further include output resolution of the output signal, and the like, for determining the size of the output signal. The position and size of the output signal in the input signal may be determined based on the first configuration information.
Of course, the signal parameter information included in the two types of first configuration information is only exemplary, and the first configuration information may also configure the position, i.e., the size, of the output signal in the input signal in other manners.
Optionally, one first configuration information may be used to configure the positions and sizes of the plurality of output signals, or each of the plurality of first configuration information is used to configure the position and size of one output signal. The control means in the signal control device may receive one or more first configuration information at a time.
In some possible implementations, the control device can generate, by the signal parameter information in the first configuration information and in combination with the image resolution of the input signal, second configuration information that can specifically instruct the processing device to read the start position of the input signal, that is, by the second configuration information, the input signal is read from the start position, and information such as the size of the read input signal. The second configuration information can also be used to indicate a mapping between the output signal and the display, i.e. on which display the output signal is specifically displayed. Optionally, the mapping relationship between the output signal and the display may be determined by the control device according to the display state of the connection signal control device, or may be configured by the first configuration information, which is not specifically limited in this embodiment of the present application.
Step S305, the processing device receives the second configuration information, and determines an output signal in the input signal according to the second configuration information.
And step S306, the processing device transmits the output signal to a display for displaying.
In some possible implementations, after receiving the second configuration information, the processing apparatus may read an output signal from a memory of the signal control device, and may transmit the output signal to a corresponding display for displaying.
Optionally, the control device may further configure a display mode of the output signal and an adjustment parameter corresponding to the display mode. The display mode of the output signal and the adjustment parameter corresponding to the display mode may be determined in real time by the peer device, or may be determined by the control device according to the state of the display, which is not specifically limited in the embodiments of the present application. For example, the first configuration information sent by the peer device carries a display mode and a corresponding adjustment parameter for the output signal, and after the control device aims at the second configuration information of the output signal according to the first configuration information and the image resolution of the input signal, the second configuration information may further include the display mode and the corresponding adjustment parameter in the first configuration information. Or after the processing device transmits the output signal to the corresponding display for display, the control device receives the display mode and the adjustment parameter for the output signal sent by the opposite-end device in real time, the control device can generate configuration information according to the received display mode and adjustment parameter, and the processing device can adjust the display mode of the output signal currently displayed on the display according to the corresponding adjustment parameter according to the configuration information. The display mode can include at least one of zooming, rotating or mirror image turning, and when the display mode is zooming, the corresponding adjusting parameter is the zooming scale; when the display mode is rotation, the corresponding adjustment parameter is a rotation angle and/or a rotation direction; when the display mode is mirror image turning, the corresponding adjusting parameter is turning direction or turning proportion, etc. Of course, the embodiments of the present application may also include other display manners, and are not limited herein.
Optionally, the display effect of the output signal may be further determined, for example, flashing the output signal, changing the color display, adding a filter effect, adding annotations at specific positions, and the like.
Optionally, when the second configuration information is used to configure a plurality of output signals, at least two output signals of the plurality of output signals may be further configured to be synchronously displayed. It should be noted that the correspondence relationship between the plurality of output signals and the display may be that the plurality of output signals correspond to one display, or one output signal corresponds to a plurality of displays, that is, each display displays the output signal, or a plurality of output signals correspond to a plurality of displays, or the like. In order to realize the synchronous display of the output signals, the clock unit in the signal control device can be used for controlling the processing device to synchronously transmit the output signals needing synchronous display, and the configuration information can be sent to the corresponding display to control the corresponding display to realize synchronous display.
It can be seen that with the above implementation, the output signal for display on the display can be determined from the input signals according to the user configuration, i.e. the display portion input signal is implemented. In this way, the requirement that the user observes the signal content required to be observed in time can be met, the display resource can be fully utilized, unnecessary signal content is prevented from being displayed, and the overall power consumption of the display is reduced. The display effect is improved, and the user experience is enhanced.
Referring to fig. 5, fig. 5 is a schematic flowchart illustrating another signal control method according to an embodiment of the present disclosure. As shown in fig. 5, the method includes at least the following steps.
Step S501, a processing device collects input signals from a signal source and sends the collected image resolution of the input signals to a control device.
In step S502, the control device receives the image resolution of the input signal.
Step S503, the processing device collects the display information of the connected displays, wherein the display information comprises the number of the displays and the display resolution of each display, and sends the display information to the control device.
In step S504, the control device receives the display information.
Step S505, the control device receives first configuration information for the input signal sent by the peer device.
In step S506, the control device determines the second configuration information for the output signal according to the first configuration information, the image resolution of the input signal, and the display information.
Step S507, the processing device receives the second configuration information, determines an output signal in the input signal according to the second configuration information, and determines a display corresponding to the output signal and a display position of the output signal on the display.
Step S508, the processing device transmits the output signal to a display for displaying.
In some possible implementations, the processing device may also collect display information of a display connected thereto. In particular, the processing means may be connected to a signal source at an input and to one or more displays at an output. The form of the connected display can be seen in the display form shown in fig. 2. The display information of the display may include the number of displays, wherein the number of displays may refer to the total number of displays connected to the signal control device, or the number of displays currently operating therein. The Display information of the Display may further include Extended Display Identification Data (EDID) information of the Display, and the EDID information of the Display may include information of Display resolution, Display frequency, and the like of the Display. The display resolution of the display refers to the maximum output resolution of the output signal that the display can support. I.e. the maximum size of the image that can be displayed that is supported by the display. Of course, the display information of the display may also include a display identifier corresponding to the display, and the like.
The processing device may send the collected display information of the display to the control device. The control device can determine second configuration information aiming at the output signal according to the image resolution of the input signal, the first configuration information sent by the opposite terminal equipment and the display information of the display. Optionally, the second configuration information may also be used to configure a display position of the output signal on the corresponding display, where this is based on that the determined output resolution of the output signal is smaller than the display resolution of the corresponding display.
Specifically, the control device may determine the output resolution of the output signal and the position of the output signal in the input signal according to the first configuration information and the image resolution of the input signal. If the output resolution of the output signal is smaller than the display resolution of the display, the display position of the output signal in the display can be further confirmed. For example, if the display position of the initial pixel point in the output signal on the display is determined, the display position of the output signal on the display can be determined, and so on. Further, if the output resolution of the output signal is smaller than the display resolution of the corresponding display, the display manner of the output signal may also be adjusted, for example, the output signal is amplified in an amplification scale, and so on. For a display area of the display device where no output signal is displayed, the display effect of the display area may be set, for example, filling a display color (e.g., black, etc.) on the display area, or adding a display effect matching an input signal on the display area, etc. The embodiments of the present application are not particularly limited.
Alternatively, the output signal may be determined based on the image resolution of the input signal, the first configuration information of the peer device, and the display resolution of the display signal, where the determined output resolution of the output signal may be smaller than or equal to the display resolution of the display signal when determined.
