The invention relates to the technical field of video conferences, and discloses a real-time document
collaborative editing and
synchronizing method in a video conference, which is used for solving the problem of insufficient concurrent editing conflict solving mechanism in the traditional method. The method comprises the following steps: firstly, receiving document editing operations submitted by a plurality of participants through a terminal, and establishing an operation sequence; comparing the timestamps with the position information, identifying concurrent operation groups as conflict sets, and arranging the conflict sets according to a
time sequence; types and contents are extracted from the conflict set,
semantic matching is carried out, matching operation is converted into a compatible sequence, and subsequent position offset is adjusted; distributing the compatible sequence to a synchronous buffer area, updating a
server document state, and generating an incremental update
package; a packet is pushed to the online terminal, application changes are buffered locally, and sequence playback is provided for a new participant; the monitoring terminal confirms the
signal, re-deduces the unconfirmed change, and circularly checks the Hash consistency; according to the method, conflict resolution is optimized through
semantic matching and offset adjustment, and efficient synchronization is achieved.
