Systems, methods, means, and media for recording, searching, and outputting display information

A system for recording display information, comprising:

• means for intercepting display-changes describing changes to be made to a state of a display;
• means for sending the display-changes to a client for display;
• means for recording the display-changes;
• and
• means for recording context information describing a state of the display derived from a source independent of the display changes and independent of screen-images.

A method for recording display information, comprising:

• intercepting display-changes describing changes to be made to a state of a display;
• sending the display-changes to a client for display;
• recording the display-changes;
• and
• recording context information describing a state of the display derived from a source independent of the display changes and independent of screen-images.

A system for recording display information, comprising:

• a virtual display that:
• intercepts display-changes describing changes to be made to a state of a display;
• sends the display-changes to a client for display;
• records the display-changes;
• and
• a context recorder that records context information derived from an accessibility mechanism and describing a state of the display

A computer-readable medium containing computer-executable instructions that, when executed by a processor, cause the processor to perform a method for recording display information, the method comprising:

• intercepting display-changes describing changes to be made to a state of a display;
• sending the display-changes to a client for display;
• recording the display-changes;
• and
• recording context information describing a state of the display derived from a source independent of the display changes and independent of screen-images.

A system for recording, searching, and outputting display information, comprising

• a display recorder that receives and stores:
• display-image-state information including a first screen-image of a display at a first time and a second screen-image of the display at a second time that is after the first time;
• display-command information including:
• at least one first command that describes advancing the first screen-image to a third screen-image of the display at a third time that is between the first time and the second time;
• and
• at least one second command that describes advancing the second screen-image to a fourth screen-image of the display at a fourth time that is after the third time;
• and
• a text recorder that receives:
• text information of text displayed at the third time from a text stream derived independently of the display-image-state information and independently of the display-command information;
• and
• text information of text displayed at the fourth time from a text stream derived independently of the display-image-state information and independently of the display-command information.
