Collaborative white board synchronous display method and device

Abstract

The application provides a collaborative white board synchronous display method and device. The method comprises the steps of: receiving a first operation data packet sent by a client, wherein the first operation data packet at least comprises operation information of operations carried out on a local collaborative white board in a network anomaly time period by the client; according to the firstoperation data packet, updating a locally stored synchronous data packet; according to the updated synchronous data packet, determining a second operation data packet, wherein the second operation data packet at least comprises operation information of operates carried out on the local collaborative white board in the client network anomaly time period by other clients; and sending the second operation data packet to the client, so that the client operates the local collaborative white board according to the second operation data packet. Application of the method can achieve an effect that after the client is offline and accesses the network again, the local collaborative white board of the client can still keep synchronous display with collaborative white boards of other clients, i.e., implement synchronous display among the collaborative white boards on different clients.

Description

technical field [0001] The present application relates to the technical field of touch screens, in particular to a method and device for synchronously displaying a collaborative whiteboard. Background technique [0002] The collaborative whiteboard can be remotely operated by multiple clients at the same time, such as writing, erasing and other operations. Specifically, when the client operates the collaborative whiteboard on the local end, the client will operate information, such as operation actions, coordinate sets, brushes, etc. Information such as color is sent to the server in real time, and the server then sends these operation information to other clients in real time, and other clients can update the content displayed on the collaborative whiteboard of the local terminal according to these operation information, so as to realize multiple clients. Synchronized displays between collaborative whiteboards. [0003] However, in practical applications, it is inevitable ...

AI Technical Summary

Problems solved by technology

[0003] However, in practical applications, it is inevitable that the client will be disconnected from the network. Then, after the client is disconnected from the network, the client cannot send its own operation information for the collaborative whiteboard to the server. It cannot receive the operation information of other clients on the collaborative whiteboard, and even if the client reconnects to the network, the operation information cannot be recovered, so that the content displayed on the collaborative whiteboard of the client is different from that of other clients. The content displayed on the collaborative whiteboard is not consistent, that is, the existing technology cannot effectively realize the synchronous display between the collaborative whiteboards on multiple clients, resulting in poor user experience
