The information of the user's input in the described step 1) is passed through the video information that video camera is taken for character image information or the user that the user imports through handwriting screen.
The quantity of a plurality of play end in the described step 1) is 2～20.
The most rational frame number that calculates in the described step 5) is the relatively current broadcast frame number information of each play end feedback of control end as the synchronization frame concrete grammar, selects a maximum current broadcast frame number of identical number as synchronization frame.
Time threshold in the described step 6) is 0.05～1 second.
A kind of electronic signature signal conditioning package of realizing that different screen is browsed in real time synchronously; It is characterized in that; This device comprises control end, hub, at least two play end, projector, projection screen, camera, handwriting screen, and described control end is connected with play end through hub, and described play end is connected with projector; Described projector is connected with projection screen, and described camera is connected with control end respectively with handwriting screen.
Described control end and play end are PC.
The quantity of described at least two play end is 2～20.
Compared with prior art, the present invention has the following advantages:
1, electronic message leaving (signature) both can free writing on the blackboard as in the past, can show, edit digitized picture, video again, attracted visitor's interest with high-tech;
2, managerial personnel can make regular check on message and Video Document, can know visitor's suggestion thus;
3, flexible configuration, be quick on the draw, characteristics such as interactivity is strong, synchronizing capacity is strong, have splendid extensibility and maintainability, can realize the demonstration that different screen is smooth in real time, thoroughly changed the limitation that tradition is browsed.
