Method to Switch Video Modes During an Online Presentation

Disclosed is a method to allow the switching of video modes within an online presentation.

The Online Presentation Control Language (OPCL) is a programming language designed to create stand-alone online presentations. Online presentations include such items as product demonstrations, tutorials, and other programs in which the computer is used to present information. An information developer, typically a non-programmer, uses the OPCL's commands to specify document structure, displayable text, sounds, animation, and other parts of the presentation.

Most online presentations have groups of related information (the OPCL defines these groups as sections); within these sections are multiple screens of information. The OPCL allows the information developer to break these sections into panels, typically one screen of information.

Previous methods of creating online presentations restricted information developers to one display mode throughout a presentation. This restriction inhibits variety and, if different modes would be optimal for different portions of a presentation, having only one mode prevents the presentation from attaining the level of quality that is desired.

The OPCL allows a person creating an online presentation to change display modes on a panel-to-panel basis. The OPCL program structure follows: Section 1
