Abstract
Methods and apparatus for creating and manipulating a video window on a display associated with a television are disclosed. A set of parameters identifying a source region and a destination location in a source coordinate system are obtained where the source coordinate system includes a source origin at a location of the source coordinate system. A destination origin is set at a location of a destination coordinate system. The source region is then translated to a location within the destination coordinate system equivalent to the destination location in the source coordinate system.
