Synchronous screenshot method, device and system and server

Abstract

The embodiment of the invention provides a synchronous screenshot method, device and system and a synchronous screenshot server. The synchronous screenshot method is applied to a selected broadcast control device of a target broadcast control device group, and the target broadcast control device group comprises the selected broadcast control device and at least one other broadcast control device. The synchronous screenshot method comprises the following steps: receiving a screenshot protocol issued by a server; based on the screenshot protocol, simultaneously sending a screenshot instruction to all or part of the broadcast control equipment in the broadcast control equipment group, wherein the screenshot instruction is used for controlling all or part of the broadcast control equipment to perform screenshot so as to obtain screenshot content; obtaining the screenshot content of all or part of the broadcast control equipment; and sending the screenshot content to the server. According to the embodiment, the problem that the screenshot time is inconsistent due to the fact that the server side directly controls the playing control equipment to carry out screenshot is avoided, a user can accurately judge the playing synchronism of a plurality of display screens, and the user experience degree is greatly improved.

Description

technical field [0001] The invention relates to the technical field of multimedia broadcast control, in particular to a method for synchronizing screenshots, a device for synchronizing screenshots, a server for synchronizing screenshots, and a system for synchronizing screenshots. Background technique [0002] In the LED display industry, there are generally application scenarios where multiple displays in an area need to play the same program content at the same time. Users are usually concerned about whether the multiple displays play the same content at the same time. Yes, but the cost of monitoring or manual inspection by installing cameras near the display is relatively high. In the prior art, a user can control a broadcast control terminal (play control device) of multiple display screens through a cloud platform (such as a server) to perform a real-time screenshot operation, and judge whether the playback of multiple display screens is synchronized by viewing the scre...

[0002] In the LED display industry, there are generally application scenarios where multiple display screens in an area need to play the same program content at the same time, and users are usually more concerned about whether the content played by the multiple display screens at the same time is the same Yes, but the cost of monitoring by installing cameras near the display screen or manual inspection is relatively high

In the prior art, the user can control the broadcast control terminal (broadcast control device) of multiple display screens through the cloud platform (such as the server) to perform real-time screenshot operations, and judge whether the playback of multiple display screens is synchronized by checking the screenshots from the cloud platform , but because the network environment of each broadcast control terminal is inconsistent, when sending a screenshot command to multiple broadcast control terminals through the cloud platform, the screenshot operation of each broadcast control terminal may not be carried out simultaneously due to network transmission delays and other issues. It will lead to the problem of inconsistency in screenshot time, so that it is impossible to accurately judge the synchronization of multiple display screens
