In this concept, a master copy of the presenter's presentation panel environment is stored onto the server, and used to achieve slide presentation synchronization between the presenter and the listeners.
VPB is a master copy of the presenter's presentation panel environment, stored onto the server and used to achieve slide presentation synchronization between the presenter and the listeners.
VPB is a data structure that defines several objects that represents the presentation panel of the presenter.
The presenter, having the right to control the presentation display panel, is the source of VPB data, wherein every slide event in its presentation display panel, a new VPB data is sent to the server.
Presentation display panel serves as the graphical screen of the slide presentation.
The presentation control panel is equipped with slide control buttons (first slide, next slide, previous slide, and last slide) that enables slide changing by the presenter, which is synchronized on the listeners' presentation display panel.
VPB data is updated by the presenter by sending the information in its presentation panel every time there is a user slide event, such as mouse click, mouse drag or button press.
When the presenter moves the default cursor and clicks at a certain position on the presentation display panel, a heavy red crosshair cursor appears, and will also be displayed on the listeners' presentation display panel.
Listener of the same content retrieves the VPB data by polling the server, and thus be able to replicate in their presentation panel similar to what is in the presenter's presentation panel.
Slide-based synchronization technology refers to mirroring of the presentation panel among the meeting participants, i.e., what the presenter see on his display panel will also be replicated on the listeners' display panel.
