Embodiment 1

[0032] Figure 2a It is a flow chart of a handwriting synchronization method provided by Embodiment 1 of the present invention. The handwriting synchronization method provided in this embodiment can be executed by a handwriting synchronization device, and the handwriting synchronization device can be realized by means of software and / or hardware, and integrated into the second device. The second device may be a smart device such as a smart tablet, a smart phone, and a video conferencing device.

[0033] refer to Figure 2a , the method specifically includes:

[0034] S110. When the first frame is displayed on the synchronization device, display the second frame on the second device.

[0035] Wherein, the synchronization device is connected to the second device through a network. When the synchronization device receives the user's operation, it can synchronously send the operation information to the second device, so that the second device and the synchronization device exe...

Embodiment 2

[0074] Figure 3a It is a flowchart of a handwriting synchronization method provided by Embodiment 2 of the present invention. In this embodiment, on the basis of the above embodiments, the step of creating the second mark of the second track is further described. refer to Figure 3a , the method provided in this embodiment specifically includes:

[0075] S210. When the first frame is displayed on the synchronization device, display the second frame on the second device.

[0076] S220. Acquire operation information of the synchronization device on the first screen.

[0077] S230. Execute the operation information on the second screen, and update the second screen according to the execution result.

[0078] S240. If there is an unmarked second track in the updated second screen, acquire a set of coordinates of the second track.

[0079] Specifically, the coordinates of each track point in the second track are acquired. Wherein, the coordinates are the coordinates of the t...

Embodiment 3

[0111] Figure 4 It is a schematic structural diagram of a handwriting synchronization device provided by Embodiment 3 of the present invention. refer to Figure 4 The handwriting synchronization device provided in this embodiment specifically includes: a display module 401 , an acquisition module 402 , an execution module 403 and a logo creation module 404 .

Abstract

The invention discloses a handwriting synchronization method, apparatus and system, and relates to the technical field of communications. The method comprises the steps of displaying a second image on a synchronization device when a first image is displayed on the synchronization device, wherein the first image is the same as the second image; obtaining operation information of the synchronization device for the first image; executing the operation information on the second image, and updating the second image according to an executive result; and if a second track without an identifier exists in the updated second image, creating the second identifier of the second track according to a method for generating an identifier on the synchronization device, thereby enabling the second identifier to be the same as a first identifier created for a corresponding first track in the updated first image by the synchronization device. By adopting the method, the technical problem that relatively high communication network bandwidth is required when track IDs are synchronized between synchronized devices can be solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a handwriting synchronization method, device and system. Background technique [0002] After synchronization, multiple remote devices can simultaneously perform synchronous operations such as displaying images, writing tracks, and erasing tracks. The specific process is that when the first device is operated by the user, it sends synchronization operation information to the other synchronized second devices, and the second device can perform the same operation as the first device according to the synchronization operation information, so as to ensure The screen is the same as that displayed by the first device. [0003] In order to better manage the tracks in the screen, an identity (identity or identification, ID) is usually created for each track after the synchronization operation is completed. When creating an identity, usually the first device creates an ID for the n...
