Fig. 2 is a schematic structural diagram of an alternative image display system according to an embodiment of the present invention, and as shown in fig. 2, the image display system includes a plurality of image source devices 104 (image source devices 104a to 104d in fig. 2), a plurality of acquirer devices 102 (acquirer device 102a to 102d in fig. 2), an image processing server 100, a plurality of receiver devices 106 (receiver devices 106a to 106d in fig. 2), and a plurality of displays 108 (displays 108a to 108d in fig. 2).
As an optional embodiment, the image source device runs a function module, where the function module may be a function application, and the function application may be installed in the image source device in advance, and is used to create an expansion screen and display an interface image of an application to be launched on the expansion screen.
The processing flow of an optional image display system provided in the embodiment of the present application may be, but is not limited to, as follows: the image processing server receives a delivery instruction issued by the user, where the delivery instruction carries the ID1 of the image source device, the ID2 of the display, and the ID3 (i.e., the first identifier ID) of the application program specified by the user for delivery. Optionally, the user may issue a delivery instruction to the image processing server through the image management system, where the image management system may operate on the image processing server or on another server; the launch command carries the ID1 of the image source device, the ID2 of the display, and the ID3 of the application the user specifies to launch.
As an optional embodiment, the launch instruction further carries a second identifier of the image source device and a third identifier of the display, and the image processing server is further configured to determine an acquisition end device corresponding to the image processing server according to the second identifier, determine a receiving end device corresponding to the display according to the third identifier, and establish a corresponding relationship between the acquisition end device and the receiving end device.
For example, the user desires to project an interface image of a certain player (ID3 ═ 011) that is running in the image source device 1(ID1 ═ 001) onto the display 1(ID2 ═ 001); the user issues a dispensing command with ID 1-001, ID 2-001, and ID 3-011. Optionally, the image processing server obtains the ID1 and the ID2 from the launching instruction 1, and establishes a correspondence between the collector device corresponding to the ID1 and the receiver device corresponding to the ID 2.
It should be noted that one image source device may correspond to multiple acquisition end devices, and the multiple acquisition devices may respectively acquire interface image data of multiple application programs in the image source device, and further send the interface image data to the corresponding receiving end devices, and each receiving end device displays the interface image on a connected display. Therefore, the interface images of the application programs running on the same image source device can be simultaneously displayed on the plurality of displays, and a user can simultaneously watch the running conditions of the application programs from the same image source device through the plurality of displays.
As an optional embodiment, the image source device is further configured to determine whether the application program to be launched is in an operating state, and if so, determine the interface image data of the application program to be launched according to the first identifier; if not, returning a display instruction to the acquisition terminal equipment; the acquisition terminal device is further configured to acquire pre-stored prompt image data according to the display instruction, and send the prompt image data to the receiving terminal device; the receiving end device is further configured to launch the prompt image data to the display.
As an alternative embodiment, since one image source device is connected to one capturing end and one display is connected to one receiving end, the capturing end device corresponding to ID1 refers to the capturing end device connected to the image source device corresponding to ID1, and the receiving end device corresponding to ID2 refers to the receiving end device connected to the display corresponding to ID 2. The image processing server acquires an ID3 from a release instruction (such as release instruction 1), and sends the release instruction (which may be different from the release instruction issued by the user, such as release instruction 2) to the acquisition terminal device corresponding to the ID1, where the release instruction carries an ID 3; and the acquisition terminal equipment forwards the putting instruction to the connected image source equipment.
For example, the ID carried in the release instruction 1 is 001, the image processing server determines, by querying a preset correspondence table between the ID1 and the image source device, that the image source device corresponding to the ID 001 is the image source device 1, and determines the acquisition end device S1 connected to the image source device 1; then, the image processing server sends the rendering instruction 2 to the acquirer S1, and the acquirer S1 forwards the rendering instruction 2 to the image source device 1.
Optionally, after receiving the release instruction 2, the function module of the image source device 1 determines the application program to be released corresponding to the ID3 carried in the release instruction 2; and judging whether the application program to be launched is running, if so, determining the interface image data of the application program to be launched according to the first identifier, and if not, continuously judging whether the application program is running.
In an optional embodiment, after receiving the launch instruction 2, the functional module first determines, according to the ID3 carried in the launch instruction 2, an application to be launched specified by a user, and determines whether the application to be launched is running, and since only the running application has an interface image and the launch in the display has a practical meaning, when determining that the application to be launched is running, the functional module continues to perform subsequent steps.
If the application program to be released is determined not to be running, whether the application program to be released is running can be continuously judged, and the subsequent steps are not continuously executed until the application program to be released is determined to be running. Of course, in practical applications, a preset time period may be set, the determination may be repeated within the preset time period, and the determination is stopped when the preset time period is exceeded, and the processing flow is ended, where the preset time period may be 10 minutes.
In practical applications, a prompt screen may be set to enable a user to know the operation status of the application program on the image source device on the display.
As an optional embodiment, after determining that the application program is not running, the functional module returns a display instruction 1 to the acquisition end, the display instruction 1 carries an ID of the prompt screen 1, and after receiving the display instruction 1, the acquisition end sends the pre-stored image data of the prompt screen 1 as the acquired image data to the receiving end, where the prompt screen 1 may include a prompt such as "the application program is not running, please wait for a short time".
As another optional embodiment, after the function module determines that the application program is not running and determines that the application program is not running through repeated judgment within a preset time period, the function module may return a display instruction 2 to the acquisition end, where the display instruction 2 carries an ID of the prompt screen 2, and after the acquisition end receives the display instruction 2, the acquisition end sends pre-stored image data of the prompt screen 2 as the acquired image data to the receiving end, where the prompt screen 2 may include a prompt such as "the application program is not running, please reselect".
In an alternative embodiment, after determining that the application to be launched is running, the function module creates an extended screen for the image source device, and sends screen information of the extended screen, which can be distinguished from the main screen, to the acquisition end device, where the screen information may include identification information of the extended screen.
In an alternative embodiment, the computer may be provided with at least one expansion screen in addition to the main screen. The desktop image of the expansion screen is the interface image of the specified application program.
In the above optional embodiment, after receiving the screen information sent by the function module, the acquisition end device determines, according to the screen information, that the screen to be acquired is an extended screen, acquires a desktop image of the extended screen, sends the acquired image data to the receiving end device, and the receiving end device recognizes and decodes the image data and displays the decoded image data on the display.
Even if other users perform other operations on the image source device, the interface image of the application program specified by the user is not displayed on the desktop, or other images besides the interface image of the application program to be launched specified by the user exist on the desktop, that is, the interface image of the application program to be launched specified by the user is not displayed on the desktop in a full screen manner.
It should be noted that the specific structure of the image display system shown in fig. 1 to 2 in the present application is only illustrative, and the image display system in the present application may have more or less structures than the image display system shown in fig. 1 to 2 in specific applications.
