Example Embodiment

[0086] Specific Example 1

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

[0088] The user A performs a whiteboard's drawing operation through the drawing end 1 on the terminal device A, and the end 1 records each of the plot operations of the user A and generates a backtrack file, and upload the backtrack file to the server 2. Generating a complete drawing process backtracking file, uploaded to the server 2 after the backchain file is uploaded, the server 2 generates a backtracking interface according to the retractable file and the retranstrum recording, and sent to the drawing end 1.

[0089] The user b acquires the backtracking interface through the tracery end 3 on the terminal device B, and establishes a short connection with the server 2, obtains the backtracking record, and generates a progress ...

[0090] Specific Example 2

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

[0092] The user c performs a whiteboard's drawing operation through the drawing end 1 on the terminal device C, and the end 1 records each plot operation of the user C and generates a backtrack file, and upload the backtrack file to the server 2, and The recording of multiple backtrooting files is generated with the backtracks, and the recording is uploaded to the server 2 in the way with the backtrack file. The server 2 generates a backtracking interface according to the retractable file and the storage position of the recording, and is sent to the drawing end 1.

[0093] The user D acquires the backtracking interface through the tracers 3 on the terminal device D, and establishes a long connection with the server 2 through...

Example Embodiment

[0094] Specific Example 3

[0095] The drawing end 1 and the backtracking end 3 are disposed on the same terminal device, where the drawing end 1 and the tracetable end 2 are both an APP end or web end on the terminal device E.

[0096] The plurality of user E establishes a long connection by the respective terminal device E and the server 2, and the plotting process is uploaded to the server 2, and the server 2 can automatically synchronize to multiple terminal equipment E according to the uploaded backtracking recording and backtrack file. E Restarting the drawing of the whiteboard based on the acquired recording and backtrip file, realizing the common drawing of many people.

[0097] Compared with the prior art, the present invention is sent to the server with a file stream to the server, and is stored by the file stream, and is stored, and the backtrack is transmitted to the server by retrofitting the data structure content, the serial number, and the timestamp of the timestam...

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...
