PURPOSE: A method and an apparatus for positioning auxiliary information proximate an auxiliary image in a multi-image display is provided to position auxiliary information, such as closed captioning text characters, that is associated with an auxiliary picture in a multi-image display proximate the auxiliary picture. CONSTITUTION: A viewer, through a remote control, defines a vertical line number(vertical position) and a pixel location(horizontal position) where one corner(e.g., upper left corner) of an PIP(Picture-in-picture) image is to be located. An active region(210) of the PIP image(202), where the PIP video is displayed, has a typical dimension of one third by one third of the size of a main picture(200). A PIP image area(210) (active region) is circumscribed by a border region(204). This border region is approximately 0.25 inches(0.64 cm) wide. In the normal operating mode, e.g., without closed captioning, the border of the PIP image is approximately 0.25 inches wide on all sides of the active image area(210). Upon activation of the closed captioning for the PIP image, a bottom border area(206) is extended to a height of approximately 2 inches (5 cm). The closed caption information is displayed in this 2 inch wide region(referred to as a closed caption window) as two-lines of closed caption text(208). The invention provides a method and apparatus for producing this extended border area(206) and positioning a closed caption information(208) within the extended border area(206) (i.e., position the caption for the PIP image proximate to the PIP active image area(210)). |
