Method and system for synchronization of simultaneous displays of related data sources

An apparatus for synchronization the presentation of data on a digital computer display, comprising:

• one or more digital computers, each capable of executing one or more tasks,
• a plurality of window-controlling tasks, each of said window-controlling tasks controlling at least one display window, each window-controlling task being executed on one of said one or more digital computers,
• a synchronization control task being executed on one of said one or more digital computers, and
• means for communications between said synchronization control task and said plurality of window-controlling tasks;
• wherein one said display window controlled by one said window-controlling task displays first information from a first source, and another said display window controlled by another window-controlling task displays second information from a second source;
• wherein said first information and said second information have sections, and at least one section of said second information corresponds to a section of said first information;
• wherein one of said plurality of window-controlling tasks sends a message to said synchronization control task over said means for communications indicating a change in viewing position to a new section of said first information;
• wherein said synchronization control task sends a message to said another of said plurality of window-controlling tasks over said means for communications requesting a change in viewing position to a section of said second information corresponding to said new section of said first information;
• and
• wherein said another window-controlling task displays said corresponding section of said second information on at least one display window.

A process capable of being executed on a digital computer for synchronizing the presentation of information from a first source and a different second source on a digital computer display, each of the information being presented having sections and at least one section of the information from said second source corresponding to a section of the information from said first source, comprising:

• a first window-controlling task recognizing a change in viewing position in a first display window to a new section,
• said first window-controlling task sending a first message to a synchronization control task indicating said change in viewing position in said first display window,
• said synchronization control task sending a second message to a second window-controlling task in response to said first message received by said synchronization control task, and
• said second window-controlling task positioning at least one display window associated with said second window-controlling task to a section corresponding to said new section.
