Patent ID: 8896612

Claim:
A digital video display system, said digital video display system comprising: a frame buffer, said frame buffer comprising a digital representation of a display screen; a frame buffer data structure defining a first set of slices specific to said frame buffer; a full-motion video window definition, said full-motion video window definition defining an area of said frame buffer wherein a full-motion video is to be displayed using a full-motion video data structure defining a second set of slices specific to a full-motion video buffer, a scale of said second set of slices being different than a scale of said first set of slices, said second set of slices representing said area of said full-motion video wherein said full-motion video is to be displayed; the full-motion video buffer, said full-motion video buffer comprising a representation of a full-motion video; an overlay window locator, said overlay window locator determining sub-areas of said full-motion video window that are obscured by at least one overlay window, said first set of slices representing a portion of said area being obscured by said at least one overlay window; and a display data reading system for a video output system, said display data reading system reading from said frame buffer while scanning said frame buffer at a location not within said full-motion video window definition or when said overlay window locator specifies an overlay window, wherein reading from said frame buffer is based on said frame buffer data structure, else from said full-motion video buffer, wherein reading from said full-motion video buffer is based on said full-motion video data structure.
