specific Embodiment 1

[0087] The drawing terminal 1 and the backtracking terminal 3 are set on different terminal devices, wherein the drawing terminal 1 is an APP terminal set on the terminal device A, and the backtracking terminal is a web terminal set on the terminal device B.

[0088] User A performs the drawing operation on the whiteboard through the drawing terminal 1 on the terminal device A. The drawing terminal 1 records each drawing operation of user A and generates a backtracking file, uploads the backtracking file to the server 2 in the form of a file stream, and Generate a backtracking recording file of the complete drawing process, and upload it to server 2 for storage after the backtracking file is uploaded. Server 2 generates a backtracking interface according to the storage location of the backtracking file and backtracking recording, and sends it to the drawing terminal 1.

[0089] User B obtains the backtracking interface through the backtracking terminal 3 on the terminal device ...

specific Embodiment 2

[0091] The drawing terminal 1 and the backtracking terminal 3 are set on different terminal devices, wherein the drawing terminal 1 is an APP terminal set on the terminal device C, and the backtracking terminal is a web terminal set on the terminal device D.

[0092] User C performs the drawing operation on the whiteboard through the drawing terminal 1 on the terminal device C. The drawing terminal 1 records each drawing operation of user C and generates a backtracking file, and uploads the backtracking file to the server 2 in the form of a file stream, and Multiple retrospective recording files are generated along with the retrospective file, and the retrospective recording is uploaded to the server 2 for storage in the form of file stream synchronously with the retrospective file.

[0093] User D obtains the backtracking interface through the backtracking terminal 3 on the terminal device D, and establishes a long connection with the server 2 through the backtracking interfac...

specific Embodiment 3

[0095] The drawing terminal 1 and the backtracking terminal 3 are set on the same terminal device, wherein both the drawing terminal 1 and the backtracking terminal 2 are APP terminals or web terminals set on the terminal device E.

[0096] Multiple users E establish long connections with the server 2 through their respective terminal devices E, and upload their drawing process to the server 2, and the server 2 can automatically synchronize to multiple terminal devices E according to the uploaded backtracking recording and backtracking files. EReproduce the drawing process of the whiteboard in real time according to the obtained backtracking recording and backtracking files, and realize the joint drawing of multiple people.

[0097] Compared with the prior art, the present invention sends the backtracking file and backtracking recording containing the whiteboard drawing data structure content, serial number and time stamp to the server as a file stream for storage, and the back...

Abstract

The invention discloses a backtracking interactive whiteboard system and a backtracking method thereof. The backtracking method comprises the following steps: a server obtains and stores a backtracking file and a backtracking record sent by a drawing end; the backtracking file carries whiteboard drawing data structure content, a serial number and a timestamp, and the backtracking file is uploaded to the server in a file stream form; the server generates a backtracking interface, and the server sends the backtracking interface to the drawing end; and the server obtains a backtracking request of a backtracking end, and sends a backtracking file to the backtracking end, so that the backtracking end reproduces the drawing process of the whiteboard. According to the method and the device, the backtracking file carrying the whiteboard drawing data structure content, the serial number and the timestamp is obtained through the server, and the backtracking file is reproduced at the backtracking end, so that backtracking of the whiteboard drawing process is realized, bandwidth occupation, flow consumption and memory occupation conditions in the interaction process are greatly reduced, and the interaction efficiency is improved. Meanwhile, the definition of the backtracking process is not limited by the video definition, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of meeting electronic information, in particular to a traceable interactive whiteboard system and a traceable method thereof. Background technique [0002] The whiteboard itself is a writing surface for repeated erasing, often used for teaching, meeting discussions, or personal and family notes. With the development of science and technology, the whiteboard is not limited to a white metal flat board with writing function, but has gradually developed into an interactive electronic whiteboard that can communicate with the computer. The interactive electronic can connect the electronic whiteboard to the PC. Use the projector to project the content on the PC to the electronic whiteboard screen. At this time, the electronic whiteboard is equivalent to a particularly large handwriting board, which can realize the functions of writing and drawing, and display or save it on the PC in real time. [0003] With the de...
