Embodiment Construction

[0017] The present invention will be further described below in conjunction with the examples, but not as a limitation of the present invention.

[0018] Please combine figure 1 , the whiteboard program involved in this embodiment, the synchronization process between the sending end and the receiving end is as follows:

[0019] 1) The server establishes a subscription for the sending and receiving users sharing the same whiteboard, and generates a subscription ID (ID);

[0020] 2) The server makes the first mirror image for the current whiteboard and starts the timer. When the specified interval time arrives, a new mirror image is made according to the previous mirror image and the synchronization message that occurred within the time interval of the timer. The new mirror image After completion, delete the synchronization message that occurred during the previous mirroring and timer interval, and reset the timer to make mirroring in a loop;

[0021] 3) When the sender logs i...

Abstract

The invention discloses a high concurrence white board remote real-time synchronization method, including the step that a server end establishes subscription for a sending end and a receiving end, and establishes an image for a current white board. The image content is updated regularly by a timer, the sending end returns the latest image and subscription identification when logging in, and the receiving end returns the latest image, the subscription identification and a synchronous message after the latest image when logging in. The sending end generates the synchronous message and sending the synchronous message together with the subscription identification to a server when operating the white board, the server stores the synchronous message and sends the synchronous message to the receiving end according to the subscription identification, and the receiving end analyzes the synchronous message to complete operation. The high concurrence white board remote real-time synchronization method is extremely low in time delay, capable of adding the receiving end at any time by subscription, and furthermore, the generated image can be used for quickly restoring the white board state.

Description

technical field [0001] The invention relates to a data method, in particular to a method for remote real-time synchronization of large concurrent whiteboards. Background technique [0002] A whiteboard is a white electronic writing board shared by teachers and students on the computer. There are generally two methods for synchronizing whiteboard data. One is to send the data directly from the sender to the receiver, and the other is to forward it through the server. The former method has limitations on the number of receivers and cannot support synchronization under large concurrency. The latter is generally relatively simple, and the server only provides forwarding services, which is easy to cause loss. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a large concurrent whiteboard remote real-time synchronization method to solve the problem of large concurrent whiteboard data synchronizatio...
