It should be noted that the image management system may include a plurality of image source devices 21, and only one image source device 21 is illustrated in fig. 2. In the image management system, one acquisition end 22 is connected with one image source device 21, one acquisition end 22 establishes a corresponding relationship with a plurality of receiving ends 23, specifically, the acquisition end 22 and the receiving ends 23 establish a corresponding relationship through a processing server 25, and in addition, one receiving end 23 is connected with a display 24.

This application sets up processing server 25 between collector 22 and receiving terminal 23, when controlling image source equipment, has two kinds of modes, firstly carries out direct control to image source equipment 21 through the input device of image source equipment 21, secondly carries out reverse control to image source equipment 21 through receiving terminal 23, when adopting above-mentioned two kinds of modes control image source equipment, and the equipment that corresponds all sends control instruction to processing server 25. When the image source device 21 is currently in the controlled state, the control state identifier stored in the processing server 25 may be an occupied state identifier, and at this time, when the image source device 21 acquires a control instruction sent from the image source device 21 or the receiving end 23, it is prompted that the image source device 21 or the receiving end 23 is currently in the controlled state and cannot perform a control operation. When the image source device 21 is currently in an uncontrolled state, the control state identifier stored in the processing server 25 may be an idle state identifier, and when the image source device 21 acquires a control instruction sent from the image source device 21 or the receiving end 23, the image source device 21 may be controlled according to the received control instruction.

In the display control system provided by the embodiment of the application, the target image is provided through the image source device 21; the acquisition end 22 is connected with the image source equipment 21 and is used for acquiring a target image; a plurality of receiving terminals 23, respectively connected to the collecting terminal 22, for receiving the target image and reversely controlling the image source device 21; a plurality of displays 24 respectively connected to the plurality of receiving terminals 23, for displaying the target images received by the receiving terminals 23; and the processing server 25 is arranged between the acquisition end 22 and the plurality of receiving ends 23, and is configured to acquire a target control instruction, and control the image source device 21 according to a stored control state identifier and the target control instruction, where the target control instruction is a reverse control instruction sent by the receiving end 23 or a control instruction sent by the image source device 21, and the control state identifier is used to indicate whether the image source device 21 is currently in a controlled state, so that the problem that operation conflicts of the image source device are caused by the presence of a plurality of receiving ends capable of performing reverse control on the image source device in an image management system in the related art is solved. When the processing server receives the control instruction, whether the image source equipment is currently in the controlled state is determined according to the control state identifier, so that the image source equipment is controlled, and the effect of avoiding the operation conflict of the image source equipment is achieved.

Fig. 3 is a flowchart of a display control method according to an embodiment of the present application. As shown in fig. 3, the display control system described above is applied, and the method includes the following steps:

step S301, receiving a target reverse control instruction through a processing server in the display control system, where the target reverse control instruction is an instruction sent by a target receiving end in the system, and the target reverse control instruction is used to control an image source device in the system.

Specifically, when a user needs to perform reverse control on the image source device, a reverse control instruction is sent to the processing server through the receiving end, and the processing server performs corresponding judgment and control after receiving the reverse control instruction.

Step S302, based on the control status identifier stored in the processing server, determines whether the image source device is currently in a controlled state or an uncontrolled state.

Specifically, after receiving a reverse control instruction sent by the receiving end, the processing server determines whether the control state identifier is an idle identifier, and if the control state identifier is an idle identifier, the processing server may allow the user to perform reverse control on the image source device through the receiving end. And if the identifier is the occupation identifier, the user is not allowed to reversely control the image source equipment through the receiving end.

Step S303, determining that the image source device is currently in an uncontrolled state under the condition that the control state identifier is the first identifier, and sending the target reverse control instruction to the image source device through the processing server.

It should be noted that the first identifier is an idle identifier, and since the control state identifier represents whether the image source device is currently in a controlled state, and indicates that the image source device is in an uncontrolled state under the condition that the control state identifier is the first identifier, a user can send a reverse control instruction issued by the receiving end to the image source device through the acquisition end, thereby implementing reverse control on the image source device.

In order to avoid the influence on the current control operation, optionally, in the display control method provided in this embodiment of the application, after determining that the image source device is currently in an uncontrolled state and sending a target reverse control instruction to the image source device through the processing server, if the control state identifier is the first identifier, the method further includes: and setting the control state identifier as a second identifier through the processing server, and setting the ID of the target receiving end as an occupied equipment identifier.

It should be noted that the second identifier is an occupied identifier, and when it is determined that the control state identifier is the second identifier, the user may be allowed to perform reverse control on the image source device, and in order to avoid being influenced by operations of other users in the operation of the user, the processing server may set the control state identifier as the occupied identifier and store the ID of the receiving end as the occupied device identifier. Therefore, the user can send the reverse control instruction issued by the receiving end to the image source device through the acquisition end, and reverse control over the image source device is achieved.

Step S304, under the condition that the control state identifier is the second identifier, determining that the image source device is currently in the controlled state, and sending a first display instruction to a target receiving end through the processing server, wherein the first display instruction is used for indicating that the image source device is in the controlled state.

It should be noted that, when the control status identifier is the second identifier, it indicates that the image source device is being directly controlled or is being reversely controlled by other receiving terminals, at this time, the user cannot implement the reverse control performed on the image source device through the receiving terminal, and the processing server may send the first display instruction to the receiving terminal to prompt the user that the user cannot perform the reverse control operation on the image source device currently.

In order to enable a user to know the current state of the image source device, optionally, in the display control method provided in the embodiment of the present application, the first display instruction includes an ID of a first prompt image, the first prompt image includes information indicating that the image source device is in a controlled state, and the first prompt image is displayed through a display corresponding to the target receiving end.

It should be noted that the first display instruction may carry an ID of the first prompt image, so that the receiving end displays the preset first prompt image corresponding to the ID on the display, where the first prompt image is used to prompt the user that the reverse control operation cannot be performed on the image source device currently. For example, the first prompt image may include a word "image source device is being operated, please wait, etc" or the like with prompt meaning.

The display control method provided by the embodiment of the application receives a target reverse control instruction through a processing server in a display control system, wherein the target reverse control instruction is an instruction sent by a target receiving end in the system, and the target reverse control instruction is used for controlling image source equipment in the system; judging whether the image source equipment is currently in a controlled state or an uncontrolled state based on the control state identification stored in the processing server; under the condition that the control state identifier is the first identifier, determining that the image source equipment is currently in an uncontrolled state, and sending a target reverse control instruction to the image source equipment through a processing server; under the condition that the control state identifier is the second identifier, the current controlled state of the image source device is determined, and a first display instruction is sent to a target receiving end through the processing server, wherein the first display instruction is used for indicating that the image source device is in the controlled state, so that the problem that operation conflicts of the image source device are caused by the fact that a plurality of receiving ends capable of reversely controlling the image source device exist in an image management system in the related art is solved. When the processing server receives the control instruction, whether the image source equipment is currently in the controlled state is determined according to the control state identifier, so that the image source equipment is controlled, and the effect of avoiding the operation conflict of the image source equipment is achieved.

In order to determine whether to stop controlling the image source device currently, optionally, in the display control method provided in this embodiment of the application, after the processing server sets the control state identifier as the second identifier and sets the ID of the target receiving end as the occupied device identifier, the method further includes: judging whether a processing server receives a reverse control instruction sent by a target receiving end corresponding to an occupied equipment identifier within preset time; and under the condition that a reverse control instruction sent by a target receiving end is not received within the preset time, setting the control state identifier as a first identifier through the processing server, and deleting the occupied equipment identifier.

It should be noted that, in the reverse control, the processing server needs to determine whether the reverse control of the receiving end corresponding to the user through the occupied device identifier is stopped; specifically, the processing server may determine whether a reverse control instruction from a receiving end corresponding to the occupied device identifier is received within a preset time, and if so, may determine that the reverse control is still being continued. If not, the reverse control can be considered to be stopped, the control state identifier can be set as an idle identifier, and the occupied device identifier is cleared, so that other users can reversely control the image source device through other receiving ends or directly control the image source device.

In order to prompt the user in time after the current control operation is finished, optionally, in the display control method provided in this embodiment of the present application, after determining that the image source device is currently in the controlled state and sending the first display instruction to the target receiving end through the processing server under the condition that the control state identifier is the second identifier, the method further includes: judging whether the control state identifier is set from the second identifier to the first identifier according to a preset period; and under the condition that the control state identifier is set to be the first identifier from the second identifier, sending a second display instruction to the target receiving end through the processing server, wherein the second display instruction is used for indicating that the image source device is in an uncontrolled state, the second display instruction comprises an ID (identity) of a second prompt image, the second prompt image comprises information representing that the image source device is in the uncontrolled state, and the second prompt image is displayed through a display corresponding to the target receiving end.

Specifically, the processing server periodically judges whether the control state identifier is converted from the occupied identifier to the idle identifier; and when the control state identifier is changed from the occupied identifier to the idle identifier, sending a second display instruction to the receiving end, wherein the second display instruction carries the ID of a second prompt image, so that the receiving end displays the preset second prompt image corresponding to the ID on the display, and the second prompt image is used for prompting a user that reverse control operation can be performed on the image source device currently.

For example, the second prompt image may include a word "image source device is already in an idle state, please operate" or the like with prompt meaning. After the user sees the second prompt image on the display connected with the receiving end, the user can send a reverse control instruction to the image source equipment through the receiving end.

Optionally, in the display control method provided in this embodiment of the present application, the method further includes: judging whether a processing server receives a control state notification message sent by an image source device, wherein the control state notification message is triggered by an operation event of an input device of the image source device, and the operation event is used for controlling the image source device; and under the condition that the processing server receives the control state notification message, setting the control state identifier as a second identifier and setting the occupied equipment identifier as the ID of the image source equipment.

Specifically, the operation event of the input device of the image source device may be a keyboard and mouse event, and after receiving the keyboard and mouse event, the image source device sends a control state notification message to the processing server, where the control state carried in the control state notification message is occupied, so that the processing server modifies the control state identifier stored in the processing server, thereby avoiding an operation conflict.

Further, after receiving the control state notification message sent by the image source device, the processing server sets the control state identifier as an occupation identifier, that is, a second identifier, according to the control state carried in the control state notification message, and sets the occupation device identifier as the ID of the image source device. Therefore, the method and the device are convenient for determining the current state of the image source device according to the control state identifier, and if the image source device is being operated, the corresponding operator can be determined according to the occupied device identifier.

In order to avoid a conflict between direct control and a current operation of the image source device, optionally, in the display control method provided in this embodiment of the application, when the processing server receives the control state notification message, the method further includes setting the control state identifier as the second identifier, and before setting the occupied device identifier as the ID of the image source device: and judging whether the control state identifier is a first identifier or not, and under the condition that the control state identifier is the first identifier, executing the steps of setting the control state identifier as a second identifier and setting the occupied equipment identifier as the ID of the image source equipment.

It should be noted that, in the above embodiment, the image source device sends the control status notification message to the processing server each time after receiving the keyboard and mouse event, that is, whether the image source device is currently controlled in the reverse direction or not, the forward control of the image source device is preferentially considered.

In this embodiment, after the image source device receives the keyboard and mouse event and the control state saved by the processing server itself is idle, a control state notification message is sent to the processing server, the control state carried by the control state notification message is occupied, after the image source device receives the keyboard and mouse event, the state of the control state saved by the image source device itself is modified to be occupied, that is, when the image source device is not currently in the controlled state, direct control is accepted.

In order to determine whether the direct operation of the image source device by the user is stopped, optionally, in the display control method provided in this embodiment of the present application, the method further includes: judging whether a processing server receives a control state notification message sent by an image source device corresponding to an occupied device identifier within preset time; and under the condition that the control state notification message sent by the image source equipment corresponding to the occupied equipment identifier is not received within the preset time, setting the control state identifier as a first identifier through the processing server, and deleting the occupied equipment identifier.

It should be noted that the processing server needs to determine whether the direct operation of the image source device by the user is stopped, specifically, the processing server may determine whether the image source device is still directly operated by the user within a preset time, and if so, the processing server may determine that the direct operation is still continued, and may repeatedly execute the step, so as to detect that the user stops the operation in time. If not, the direct operation can be considered to be stopped, the control state identifier can be set to be idle, and the occupied equipment identifier is cleared, so that a user can perform reverse control on the image source equipment through the receiving end.

Fig. 4 is a flowchart of another display control method according to an embodiment of the present application. As shown in fig. 4, with the above display control system, the method includes the following steps:

step S401, receiving a target control instruction through a processing server in the display control system, where the target control instruction is used to control an image source device in the system, the target control instruction is an instruction sent by the target device, and the target device is the image source device or a target receiving end in the system.

Specifically, when a user needs to perform reverse control on the image source device, a reverse control instruction is sent to the processing server through the receiving end, and the processing server receives the reverse control instruction and performs corresponding judgment and control. In addition, when the user needs to directly control the image source device, the user also sends a control instruction to the processing server, and the processing server receives the control instruction and performs corresponding judgment and control.

Step S402, based on the control status identifier stored in the processing server, determines whether the image source device is currently in a controlled state or an uncontrolled state.

Specifically, after receiving the target control instruction, the processing server determines whether the control state identifier is an idle identifier, and if the control state identifier is an idle identifier, the processing server may allow the user to perform reverse control on the image source device through the receiving end, or directly control the image source device through the input device of the image source device, and if the control state identifier is an occupied identifier, the processing server may not allow the image source device to perform reverse control or direct control.

Step S403, determining that the image source device is currently in an uncontrolled state under the condition that the control state identifier is the first identifier, and controlling the image source device through the target control instruction.

It should be noted that the first identifier is an idle identifier, and since the control state identifier represents whether the image source device is currently in a controlled state, and indicates that the image source device is in an uncontrolled state under the condition that the control state identifier is the first identifier, a user can send a reverse control instruction issued by the receiving end to the image source device through the acquisition end, so as to implement reverse control on the image source device, and the user can also directly control the image source device through the input device.

In order to determine whether to stop controlling the image source device currently, optionally, in the display control method provided in this embodiment of the application, in a case that the control state identifier is the first identifier, it is determined that the image source device is currently in an uncontrolled state, and after the image source device is controlled by the target control instruction, the method further includes: judging whether the processing server receives a control instruction sent by the target equipment within preset time; and under the condition that the control instruction sent by the target equipment is not received within the preset time, setting the control state identifier as a first identifier through the processing server.

It should be noted that, in the process of controlling the image source device, the processing server needs to determine whether the user stops controlling the image source device by using the device corresponding to the device identifier; specifically, the processing server may determine whether a control instruction from the device corresponding to the occupied device identifier is received within a preset time, and if so, may determine that the current control is still continuing, and if not, may determine that the current control has stopped, may set the control state identifier as an idle identifier, and clears the occupied device identifier, so that other users may perform reverse control on the image source device through other receiving terminals or directly control the image source device.

Step S404, determining that the image source device is currently in the controlled state under the condition that the control state identifier is the second identifier, and sending a first display instruction to the target device through the processing server, where the first display instruction is used to indicate that the image source device is in the controlled state.

It should be noted that, when the control status identifier is the second identifier, it indicates that the image source device is being reversely controlled or directly controlled by other receiving terminals, at this time, the user cannot implement the reverse control performed on the image source device through the receiving terminal, and the processing server may send the first display instruction to the receiving terminal to prompt the user that the user cannot currently perform the reverse control operation on the image source device.

In order to prompt the user in time after the current control operation is finished, optionally, in the display control method provided in this embodiment of the present application, in a case that the control state identifier is the second identifier, it is determined that the image source device is currently in the controlled state, and after the processing server sends the first display instruction to the target device, the method further includes: judging whether the control state identifier is set from the second identifier to the first identifier according to a preset period; and under the condition that the control state identifier is set from the second identifier to the first identifier, sending a second display instruction to the target device through the processing server, wherein the second display instruction is used for indicating that the image source device is in an uncontrolled state.

Specifically, the processing server periodically judges whether the control state identifier is changed from occupied to idle; and when the control state identifier is changed from occupied to idle, sending a second display instruction to the receiving end or the image source equipment, wherein the second display instruction carries the ID of a second prompt image, so that the receiving end or the image source equipment displays the preset second prompt image corresponding to the ID on the display, and the second prompt image is used for prompting a user that the image source equipment can be controlled and operated currently.

The display control method provided by the embodiment of the application receives a target control instruction through a processing server in a display control system, wherein the target control instruction is used for controlling image source equipment in the system, the target control instruction is an instruction sent by the target equipment, and the target equipment is the image source equipment or a target receiving end in the system; judging whether the image source equipment is currently in a controlled state or an uncontrolled state based on the control state identification stored in the processing server; under the condition that the control state identifier is the first identifier, determining that the image source equipment is currently in an uncontrolled state, and controlling the image source equipment through a target control instruction; under the condition that the control state identifier is the second identifier, determining that the image source device is currently in the controlled state, and sending a first display instruction to the target device through the processing server, wherein the first display instruction is used for indicating that the image source device is in the controlled state, so that the problem that operation conflicts of the image source device are caused by the fact that a plurality of receiving ends capable of reversely controlling the image source device exist in an image management system in the related art is solved. When the processing server receives the control instruction, whether the image source equipment is currently in the controlled state is determined according to the control state identifier, so that the image source equipment is controlled, and the effect of avoiding the operation conflict of the image source equipment is achieved.

It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than presented herein.
