ABSTRACT:
A computer display system and method for displaying a sequence of video images in a portion of a graphic display. The video images are provided to the system along with a first set commands that define the size of the images relative to the display as well as their position for insertion into the display. A command modifier, internal to the display system modifies the first set of video image size/position commands to produce a second set of commands. These modifications are performed by the command modifier in response to signals such as from user-generated commands. The second set of video image size/position commands are then forwarded, respectively to a scaling unit and a image insertion unit. The scaling unit scales the video image signals based on the size commands contained in the second set of commands. The insertion unit inserts the scaled video image sequence into the graphics display based on the second set of commands.
