The selected broadcast control device and the first broadcast control device 210 receive the screenshot content, and then send the screenshot content (i.e., the first screenshot content, the second screenshot content, and the third screenshot content) to the server 100, and after receiving the screenshot content, the server 100 may display the screenshot content on a terminal management page, for example, to help a user accurately judge the synchronization of the multiple display screens controlled by multiple broadcast control devices.
In summary, the synchronous screenshot system provided in the first embodiment of the present invention receives a screenshot protocol issued by a server through a selected broadcast control device, and then simultaneously sends a screenshot instruction to all or some broadcast control devices in the broadcast control device group based on the screenshot protocol, so as to control all or some broadcast control devices to perform screenshot to obtain screenshot content, and then the selected broadcast control device sends the screenshot content of all or some broadcast control devices to the server, so as to complete synchronous screenshot of all or some broadcast control terminals.
[ second embodiment ]
As shown in fig. 2, a synchronous screenshot method provided in a second embodiment of the present invention is applied to a selected broadcast control device in a target broadcast control device group, where the target broadcast control device group includes the selected broadcast control device and at least one other broadcast control device. The synchronous screenshot method relates to the server 100 and the broadcast control device group 200, and the specific functions of the server 100 and the broadcast control device group 200 are the same as those of the first embodiment, and are not described herein again. The synchronous screenshot method comprises the following steps:
s10, receiving a screenshot protocol issued by a server;
s20, based on the screenshot protocol, simultaneously sending a screenshot instruction to all or part of the broadcast control devices in the broadcast control device group, wherein the screenshot instruction is used for controlling all or part of the broadcast control devices to perform screenshot so as to obtain screenshot content;
s30, acquiring the screenshot content of all or part of the playing control equipment;
and S40, sending the screenshot content to the server.
Specifically, the server 100 may generate a screenshot protocol according to the playback device selected by the user and the screenshot information, where the screenshot protocol may include the screenshot information, and may also include, for example, a playback device identifier of the playback device group, where the playback device identifier is, for example, a unique identifier of each playback device, and specifically may be, for example, an ID number, which is not limited to this, of course. The server 100 sends the generated screenshot protocol to a selected broadcast control device, the selected broadcast control device, for example, the first broadcast control device 210 in the broadcast control device group 200 receives the screenshot protocol, analyzes the screenshot protocol after receiving the screenshot protocol, then confirms that the selected broadcast control device is a main broadcast control device according to the identifier of the broadcast control device in the screenshot protocol, generates a screenshot instruction according to the analyzed screenshot protocol, for example, screenshot information and the identifier of the broadcast control device, specifically, for example, assembles the analyzed screenshot protocol according to a Lora protocol to generate a screenshot instruction, and then sends the screenshot instruction to all or part of the broadcast control devices in the broadcast control device group 200, where all or part of the broadcast control devices are all broadcast control devices in the broadcast control device group 200, and certainly includes the selected broadcast control device, that is the selected broadcast control device sends the screenshot instruction to itself and other broadcast control devices at the same time, for example, the first broadcast control device 210 sends the screenshot command to the first broadcast control device 210, the second broadcast control device 220, and the third broadcast control device 230 at the same time. Of course, the Lora protocol is only an example, and the screenshot instruction may be generated according to an actual requirement and a corresponding protocol, which is not limited in the embodiment of the present invention.
As mentioned above, the screenshot instruction is used to control all or some of the broadcast control devices to perform respective screenshot to obtain screenshot content, and return the screenshot content to the selected broadcast control device, and then the selected broadcast control device forwards the screenshot content to the server 100. Therefore, the problem that the screenshot time is inconsistent due to the fact that the server side directly controls the playing control equipment to conduct screenshot is avoided, the user can conveniently and accurately judge the playing synchronism of the display screens, and the user experience degree is greatly improved.
In a specific implementation manner of this embodiment, the selected broadcast control device may further generate a screenshot result, and then send the screenshot result to the server 100. The screenshot result comprises screenshot success, screenshot failure and screenshot abnormity; the screenshot success is that the selected broadcast control device is online and all or part of the broadcast control devices are successfully screenshot, the screenshot failure is that the selected broadcast control device is online and all or part of the broadcast control devices have screenshot failure, and the screenshot abnormality comprises that the selected broadcast control device is not online and/or all or part of the other broadcast control devices have offline. Therefore, the user can perform corresponding operation according to the screenshot result, and the user experience is improved.
In one embodiment of this embodiment, each of the broadcast devices in the broadcast device group 200 has the same system time. Specifically, each of the broadcast control devices in the broadcast control device group 200 (for example, the first broadcast control device 210, the second broadcast control device 220, and the third broadcast control device 230) is provided with, for example, a wireless spread spectrum communication module, for example, a Lora module, through which the first broadcast control device 210, the second broadcast control device 220, and the third broadcast control device 230 are timed, so that each of the broadcast control devices in the broadcast control device group 200 has the same system time. Therefore, the multiple display screens controlled by each broadcast control device in the broadcast control device group 200 can be ensured to play the same content at the same time, so that the multiple screenshot contents obtained during synchronous screenshot are ensured to be the same, and a user can accurately judge the playing synchronism of the multiple display screens.
In a specific implementation manner of this embodiment, each of the broadcast control devices in the broadcast control device group 200 is in the same local area network. Specifically, for example, the first broadcast device 210, the second broadcast device 220, and the third broadcast device 230 may all be in the same local area network and connected through the network. Because the networking complexity in the same local area network is low, the communication delay among the multiple broadcast control devices in the broadcast control device group 200 is small and can be ignored, so that when the selected broadcast control device in the broadcast control device group simultaneously sends a screenshot instruction to all or part of the broadcast control devices, all or part of the broadcast control devices can simultaneously receive the screenshot instruction, and the simultaneity of screenshot of the multiple broadcast control devices is ensured.
In summary, in the synchronous screenshot method provided in this embodiment, a selected broadcast control device receives a screenshot protocol issued by a server, and then simultaneously sends a screenshot instruction to all or some broadcast control devices in the broadcast control device group based on the screenshot protocol, so as to control all or some broadcast control devices to perform screenshot to obtain screenshot content, and then the selected broadcast control device sends the screenshot content of all or some broadcast control devices to the server, so as to complete synchronous screenshot of all or some broadcast control terminals.
[ third embodiment ]

The synchronous screenshot method comprises the following steps:
s100, acquiring a broadcast control device identifier in a target broadcast control device group, and generating a screenshot protocol based on the broadcast control device identifier and screenshot information, wherein the target broadcast control device group comprises a selected broadcast control device and at least one other broadcast control device;
s200, sending the screenshot protocol to the selected broadcast control equipment so that the selected broadcast control equipment controls all or part of the broadcast control equipment in the target broadcast control equipment group to perform screenshot according to the screenshot protocol to obtain screenshot content;
and S300, receiving the screenshot content sent by the selected broadcast control equipment.
Specifically, the user may access the service end 100 to obtain the terminal management page through, for example, browser software installed on a personal computer, the user may manage the broadcast control device group 200 through, for example, the terminal management page, specify, for example, by checking and the like, that the first broadcast control device group 210 in the broadcast control device group 100 is a master broadcast control device, that is, a selected broadcast control device, specify, for example, that other broadcast control devices (the second broadcast control device 220 and the third broadcast control device 230) in the broadcast control device group 100 are slave broadcast control devices, and generate, for example, through a screenshot button on the terminal management page, the service end 100 generates a screenshot protocol in response to the user operation, for example, obtains, according to the above specification of the user, the broadcast control device identifiers of the broadcast control device group, and specifically, for example, the identifiers of the selected broadcast control device and identifiers of all or part of the other broadcast control devices, for example, the identifiers of the selected broadcast control device are specified as the master broadcast control device in the screenshot protocol, all or part of the identifiers of other broadcast control devices are designated as slave broadcast control devices, the server generates a screenshot protocol based on the identifiers of the broadcast control devices and screenshot information, and sends the screenshot protocol to a selected broadcast control device, so that the selected broadcast control device controls all or part of the broadcast control devices in the broadcast control device group 200 to simultaneously screenshot according to the screenshot protocol to obtain screenshot contents of all or part of the broadcast control devices, and forwards the screenshot contents to the server 100. The screenshot protocol may include, for example, a broadcast control device identifier and screenshot information, where the broadcast control device identifier may, for example, indicate that the first broadcast control device 210 is a selected broadcast control device, that is, a master broadcast control device, the second broadcast control device 220 is a slave broadcast control device, and the third broadcast control device 230 is a slave broadcast control device, and the screenshot information is, for example, used to control the broadcast control device to perform screenshot, which is, of course, only an example here, and the embodiments of the present invention are not limited thereto.
As mentioned above, the server 100 receives the screenshot content sent by the selected broadcast control device, and may display the screenshot content on a terminal management page of a personal computer, for example, to help a user accurately determine the synchronization of the multiple display screens controlled by multiple broadcast control devices.
Referring to fig. 4, the method for synchronously capturing a screenshot further includes the steps of:
s400, receiving a screenshot result fed back by the selected broadcast control equipment;
s500, generating corresponding prompt information according to the screenshot result;
s600, displaying the prompt information;
specifically, the first broadcast control device 210 selects a broadcast control device to generate a screenshot result, and feeds the screenshot result back to the server 100, and the server 100 receives the screenshot result, then generates corresponding prompt information according to the screenshot result, and displays the prompt information through the web client. The screenshot result comprises screenshot success, screenshot failure and screenshot abnormity; the screenshot success is that the selected broadcast control device is online and all or part of the broadcast control devices are successfully screenshot, the screenshot failure is that the selected broadcast control device is online and all or part of the broadcast control devices have screenshot failure, and the screenshot abnormality comprises that the selected broadcast control device is not online and/or all or part of the other broadcast control devices have offline. For example, when the main playback device selected by the user, for example, the first playback device 100, is not online, the user is prompted that the main playback device is not online and cannot perform synchronous screenshot normally, and it is recommended to perform synchronous screenshot after replacing the online main playback device; when a slave broadcast control device in the broadcast control device group 200, for example, the second broadcast control device 220, is not on-line, prompting that the corresponding broadcast control device (i.e., the second broadcast control device 220) is not on-line; when the screenshot fails in an abnormal condition, displaying the screenshot condition of the corresponding broadcast control equipment; of course, the above are all illustrations, and the embodiments of the present invention are not limited thereto. Therefore, the screenshot condition of the broadcast control equipment can be fed back to the user, and the user experience is improved.
In one embodiment of this embodiment, each of the broadcast devices in the broadcast device group 200 has the same system time. Specifically, each of the broadcast control devices in the broadcast control device group 200 (for example, the first broadcast control device 210, the second broadcast control device 220, and the third broadcast control device 230) is provided with, for example, a wireless spread spectrum communication module, for example, an Lora module, through which the first broadcast control device 210, the second broadcast control device 220, and the third broadcast control device 230 are paired, so that each of the broadcast control devices in the broadcast control device group 200 has the same system time. Therefore, the multiple display screens controlled by each broadcast control device in the broadcast control device group 200 can be ensured to play the same content at the same time, so that the multiple screenshot contents obtained during synchronous screenshot are ensured to be the same, and a user can accurately judge the playing synchronism of the multiple display screens.
In a specific implementation manner of this embodiment, each of the broadcast control devices in the broadcast control device group 200 is in the same local area network. Specifically, for example, the first broadcast device 210, the second broadcast device 220, and the third broadcast device 230 may all be in the same local area network and connected through the network. Because the networking complexity in the same local area network is low, the communication delay among the multiple broadcast control devices in the broadcast control device group 200 is small and can be ignored, and thus when the selected broadcast control device in the broadcast control device group simultaneously sends a screenshot instruction to all or part of the broadcast control devices, all or part of the broadcast control devices can be ensured to simultaneously receive the screenshot instruction, so that the screenshot simultaneity of the multiple broadcast control devices is ensured.
In summary, in the synchronous screenshot method provided in the third embodiment of the present invention, a selected broadcast control device receives a screenshot protocol issued by a server, and then simultaneously sends a screenshot instruction to all or part of broadcast control devices in the broadcast control device group based on the screenshot protocol, so as to control all or part of the broadcast control devices to perform screenshot to obtain screenshot content, and then the selected broadcast control device sends the screenshot content of all or part of the broadcast control devices to the server, so as to complete synchronous screenshot of all or part of the broadcast control terminals.
